Description
PRIORITY CLAIM
[0001]The present application claims the benefit of U.S. Provisional Application 63/738,283, filed Dec. 23, 2024. U.S. Provisional Application 63/738,283 is incorporated herein by reference in its entirety.
FIELD
[0002]The present disclosure relates generally to a temperature-controlled work surface system and temperature-controlled seat in which the temperature of the work surface system, the temperature-controlled seat, or the area surrounding the temperature-controlled work surface system or temperature-controlled seat can be regulated.
BACKGROUND
[0003]The temperature of a workspace can be controlled using various approaches that can be based on factors including the size of the workspace, the number of people in the workspace, or the spatial configuration of the workspace. In some instances, workspaces may include individual office spaces that are connected to a heating and cooling system that provides a uniform climate for offices and does not allow for individual control of the temperature in each office. In other instances, a workplace can comprise an open floorplan in which there are no individual offices or partitions between individuals, thereby limiting the ability to control the climate for different portions of the workspace.
[0004]Under circumstances in which the climate in an individual workspace can be controlled, the location of windows, doors, and heating or cooling ducts can increase the complexity involved in providing a comfortable workspace climate. Further, adjusting the temperature in a large entire area can result in changes in the humidity such that some individuals may find their immediate area to be too moist or too dry for comfort. Additionally, different portions of an individual's body may require different temperatures to be comfortable. For example, an individual's feet may require more heat than their back and another individual may feel more comfortable when the temperature of their upper legs is cooler than the temperature of their feet. As such, regulating the temperature in a workplace can present a challenge.
SUMMARY
[0005]Aspects and advantages of embodiments of the present disclosure will be set forth in part in the following description, or can be learned from the description, or can be learned through practice of the embodiments.
[0006]One example aspect of the present disclosure is directed to a temperature-controlled work surface and seat system that can comprise a temperature-controlled work surface and a temperature-controlled seat. A temperature-controlled work surface system can comprise a base. A surface member comprising an upper surface and a lower surface can be mounted to the base. The temperature-controlled work surface system can comprise a housing mounted to the lower surface of the surface member. The temperature-controlled work surface system can comprise one or more conduits disposed within the housing. The one or more conduits comprise one or more inlets and one or more outlets. The temperature-controlled work surface system can comprise a temperature regulation device mounted to the one or more inlets of the one or more conduits and configured to modify a temperature of air. The temperature-controlled work surface system can comprise a fluid flow generator mounted to the temperature regulation device. The fluid flow generator is configured to draw air into the fluid flow generator and direct a flow of the air into the temperature regulation device and through the one or more inlets to the one or more outlets of the one or more conduits. The temperature-controlled work surface system can comprise a controller coupled to the surface member and configured to control the temperature regulation device or the fluid flow generator.
[0007]A temperature-controlled seat can comprise a base member comprising one or more base member conduits disposed within the base member and configured to convey fluid through the one or more base member conduits. The temperature-controlled seat can comprise a backrest member coupled to the base member. The backrest member comprises one or more backrest member conduits that are disposed within the backrest member and configured to convey the fluid through the one or more backrest member conduits. The temperature-controlled seat can comprise a fluid flow generator coupled to the one or more base member conduits and the one or more backrest member conduits. The fluid flow generator is configured to direct the fluid through the one or more base member conduits or the one or more backrest member conduits. The temperature-controlled seat can comprise a temperature regulation device coupled to the fluid flow generator and configured to modify a temperature of the fluid directed through the one or more base member conduits or the one or more backrest member conduits. The temperature-controlled seat can comprise a controller coupled to the base member and configured to control the fluid flow generator or the temperature regulation device.
[0008]These and other features, aspects, and advantages of various embodiments of the present disclosure will become better understood with reference to the following description and appended claims. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate example embodiments of the present disclosure and, together with the description, serve to explain the related principles.

DETAILED DESCRIPTION
[0024]Reference now will be made in detail to embodiments, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the embodiments, not limitation of the present disclosure. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments without departing from the scope or spirit of the present disclosure. For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that aspects of the present disclosure cover such modifications and variations.
[0025]As used herein, the terms “first,” “second,” and “third” may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components. The terms “includes” and “including” are intended to be inclusive in a manner similar to the term “comprising.” Similarly, the term “or” is generally intended to be inclusive (i.e., “A or B” is intended to mean “A or B or both”).
[0026]Approximating language, as used herein throughout the specification and claims, is applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term or terms, such as “about,” “approximately,” and “substantially,” are not to be limited to the precise value specified. In at least some instances, the approximating language may correspond to the precision of an instrument for measuring the value. For example, the approximating language may refer to being within a ten percent (10%) margin.
[0027]In general, the present disclosure is directed to a temperature-controlled work surface and seat system that may comprise a temperature-controlled work surface system that regulates the temperature in proximity to the user of the work surface and a temperature-controlled seat that regulates the temperature of the seat in which a user is seated. The temperature-controlled work surface system is configured to heat or cool one or multiple parts of a user's body. The temperature-controlled seat may provide targeted heating to different parts of the user's body and can be configured as either a detachable device or as a unified temperature-controlled chair that incorporates the temperature-controlled seat. As described herein, the temperature-controlled work surface system is a lightweight and energy efficient technology that is configured to regulate the temperature in an area (e.g., an area within 2.0 meters of the work surface) surrounding the work surface. Given that individuals in shared workspaces may have different temperature preferences, the temperature-controlled work surface system can provide an individualized temperature zone for a person in a workspace. Further, the temperature-controlled workspace is configured to provide heating and cooling in standing or sitting positions (e.g., for standing desks or regular desks). By providing distinct, user-adjustable airflow paths through various conduits, the temperature-controlled work surface system can adapt to the dynamic nature of modern workspaces, accommodating users who frequently transition between sitting and standing postures.
[0028]The temperature-controlled seat can be portable in addition to being lightweight. The temperature-controlled seat provides targeted heating via a fluid circulation system that circulates fluid through conduits. The temperature-controlled seat may also be powered by a battery that can supply a long duration charge while allowing the temperature-controlled seat to retain its portability without being tethered to a wall plug. Further, the temperature-controlled seat is ergonomically configured to be supportive without being too hard. Further, the temperature-controlled seat is soft and supportive as well as being covered in carefully selected fabrics that enhance user comfort. The temperature-controlled work surface system and the temperature-controlled seat provide more efficient heating and cooling by having lower power requirements and regulating the temperature in a small area instead of a large area that may not have many people in it.
[0029]With reference to the figures, a temperature-controlled work surface system 100 will be described in accordance with example aspects of the present subject matter. As discussed in greater detail below, temperature-controlled work surface system 100 may include features for regulating the temperature in a workspace. The temperature-controlled work surface system 100 may define a vertical direction V, a lateral direction L, and a transverse direction T. The vertical direction V, the lateral direction L, and the transverse direction T may be mutually perpendicular and form an orthogonal direction system.

[0032]While
[0033]The housing 120 can act as the structural enclosure for the temperature-controlled work surface system 100, protecting the internal mechanisms and improving the safety of operation. The housing 120 can be constructed from one or more materials comprising Nylon (e.g., Nylon 12), aluminum, or other heat-resistant polymers that can provide durability while remaining lightweight.
[0034]The housing 120 can be configured to be low-profile, to increase legroom, and reduce physical interference with a user seated or standing at the surface member 110. One or more conduits 130 can be disposed within the housing 120. The conduits 130 can define airflow paths through the temperature-controlled work surface system 100, guiding air from an intake point to target zones around a user. The conduits 130 can be configured so that heating and cooling can be performed effectively. Further, the conduits 130 can comprise a split-flow configuration in which upper conduits and lower conduits can be directed at different body parts of a user (e.g., the user's chest and legs). Further, the structure of the conduits 130 can comprise a variety of materials including various plastics, silicone, flexible polymer, aluminum, and/or steel.
[0035]As depicted in the internal configuration of the housing 120 in
[0036]The temperature regulation device 140 can be mounted to the one or more inlets 136 of the conduits 130 and is the core component for modifying the temperature of the air. The temperature regulation device 140 can comprise a ceramic heating element (e.g., a Positive Temperature Coefficient (PTC) thermistor). This type of heating element can provide safety benefits, as it self-regulates its temperature to prevent overheating, and allows for rapid heating times. The temperature regulation device 140 can be configured to modulate its output power (e.g., switching between 50 watts, 100 watts, and 150 watts) to provide varying levels of thermal intensity based on user preference. When the temperature-controlled work surface system 100 is active in a heating mode, the air propelled by the fluid flow generator 150 can pass over or through the temperature regulation device 140, absorbing thermal energy before entering the conduits 130.
[0037]The conduits 130 can be configured to distribute air through one or more outlets 138. The conduit system can comprise one or more upper conduits 132 and/or one or more lower conduits 134. This separation allows for a split-flow configuration, where the upper conduits 132 may direct air in a forward direction (substantially parallel to the lower surface 114) to target the user's torso or hands, while the lower conduits 134 direct air downward (for example, at an angle up to 75 degrees relative to the lower surface 114) to target the user's legs and feet. This targeted distribution can result in a more comfortable thermal balance, particularly when the user is in a standing position where the distance between the device and the lower limbs is greater. The internal geometry of the conduits 130, which can be substantially toroid or serpentine in shape, can maintain air pressure and velocity, such that the airflow reaches the user with sufficient force to be effective but without creating uncomfortable drafts.
[0038]Control over these various functions can be managed by a controller 160, which is coupled to the surface member 110 or integrated into the housing 120 in a position accessible to the user. The controller 160 can comprise the control interface 161 and/or the control interface 162 which provide a user interface for the temperature-controlled work surface system 100. The controller 160 may comprise various interfaces including rotary knobs, distinct buttons, or a touch interface that allows the user to select between heating and cooling modes, adjust the intensity of the fluid flow generator 150, and regulate the output of the temperature regulation device 140. For example, the control interface 161 can be used to modify a temperature of the air heated or cooled by the temperature regulation device 140. Further, the control interface 162 can be used to regulate the direction of air that is outputted by from the conduits 132, 134. For example, the control interface 162 can be used to direct air from the conduits towards a user's torso, a user's feet, or a user's torso and feet. Furthermore, the controller 160 may interface with a diverter control device 170 within the housing 120. The diverter control device 170 allows the user to mechanically and/or electronically manipulate the airflow ratio between the upper conduits 132 and lower conduits 134, enabling a transition from 100% forward flow, to a 50/50 split, to 100% downward flow. The controller 160 may also include visual indicators, such as light emitting diodes (LEDs), to display the current mode (e.g., red for heat and/or blue for cooling) and operational status. Through the cooperative operation of the housing 120, conduits 130, temperature regulation device 140, fluid flow generator 150, and controller 160, the temperature-controlled work surface system 100 can provide an efficient, localized climate solution.
[0039]
[0040]The inlets 136 can be positioned to draw ambient air from the environment with less resistance. In some embodiments, the inlets 136 can comprise a grilled or perforated interface to prevent the ingress of foreign objects while maximizing air intake volume. The air drawn through the inlets 136 can be acted upon by the fluid flow generator 150 located within the housing 120. While the internal components are shielded, the positioning of the fluid flow generator 150 can be centrally or rearwardly disposed to improve the center of gravity and reduce vibration transfer to the surface member 110. In some embodiments, the fluid flow generator 150, may comprise a direct current (DC) tangential fan, and can be configured to drive air at velocities ranging from 0.20 meters per second to 0.35 meters per second, creating a gentle yet effective breeze that facilitates convective or evaporative cooling without generating distracting noise, maintaining acoustic levels below 19 decibels during operation.
[0041]The outlets 138 can be arranged to discharge conditioned air in at least two distinct vectors. A first set of outlets, corresponding to the upper conduits 132 can be oriented to direct air substantially parallel to the lower surface 114, projecting the air forward toward the user's torso. A second set of outlets, corresponding to the lower conduits 134, can be oriented to direct air downwardly.
[0042]
[0043]The mounting interface of the housing 120 is also visible in
[0044]Furthermore,
[0045]
[0046]
[0047]The lower conduit 134 can be disposed beneath the upper conduit 132 and can be geometrically configured to direct a second stream of conditioned air in a downward trajectory. As depicted in the side profile of
[0048]The interaction between the upper conduit 132 and the lower conduit 134 is managed by the diverter control device 170, the external interface of which is represented by the controller 160. In the view of
[0049]Furthermore, the side view highlights the power management integration. The controller 160 can comprise a battery pack (e.g., a rechargeable battery pack comprising a lithium-ion array, a lithium iron phosphate battery, a nickel metal hydride battery, or a silicone battery) that can provide energy for the temperature regulation device 140 and/or the fluid flow generator 150.
[0050]Furthermore,
[0051]
[0052]The rear outlet 191 may function as an intake manifold or an auxiliary exhaust. In embodiments utilizing a tangential fan or crossflow blower as the fluid flow generator, the rear outlet 191 can be positioned to draw ambient air into the housing 120 with less resistance. The placement of the rear outlet 191 can be configured to avoid occlusion by the user's knees or the work surface structure itself. Air drawn through the rear outlet 191 can be regulated (e.g., heated by the PTC thermistor elements or accelerated for cooling) before being moved into the split conduit system. The configuration of the rear outlet 191 may include a mesh or grille structure to prevent the ingress of debris while maximizing the volumetric intake required to sustain the preferred airflow rates.
[0053]In this rearward orientation, the rear outlet 191 is visible. The rear outlet 191 can function as a primary air intake for the temperature-controlled work surface system 100. The rear outlet 191 is configured with a larger surface area to reduce static pressure drop as air is drawn into the housing 120. The rear outlet 191 may comprise a series of louvers, a mesh grille, or a perforated panel integrated directly into the sidewall or rear wall of the housing 120. For example, the rear outlet 191 may feature a honeycomb lattice structure that maximizes airflow permeability while preventing the ingress of larger objects, such as cables or office supplies that might be present under a work surface. The positioning of the rear outlet 191 can allow the rear outlet 191 to draw from the cooler, ambient air mass located beneath the work surface, rather than recirculating the pre-conditioned air that has just been expelled toward the user from the front outlets.

[0060]The one or more inlets 136 are disposed at the proximal end of the conduit assembly 130. As illustrated, the inlet 136 defines a receiving aperture configured to couple directly with the downstream side of the temperature regulation device. The geometry of the inlet 136 can be configured to receive the volumetric output of the fluid flow generator without creating back-pressure that could stall the fan blades or cause overheating of the heating elements. For example, the cross-sectional area of the inlet 136 can be matched to the discharge area of a tangential fan to result in a seamless transition of air. The internal surface of the inlet 136 is preferably smooth and devoid of sharp angles to prevent the formation of turbulent eddies that generate acoustic noise. In operation, as air carrying thermal energy (e.g., heated to 45 degrees Celsius) enters the inlet 136, it is immediately channeled into the distribution manifold formed by the junction of the upper and lower conduits.
[0061]Extending distally from the inlet 136 is the one or more upper conduits 132.
[0062]Diverging from the upper conduit 132 is the one or more lower conduits 134. As shown in the side profile of
[0063]The distal ends of the conduits can terminate in the one or more outlets 138.

[0067]
[0068]The base 190 represents the structural framework of the work surface. In the embodiment depicted in
[0069]Mounted to the top of the base 190 is the surface member 110. The surface member 110 is the primary user interface for the workspace, defining the horizontal plane upon which work is conducted. As shown in
[0070]The lower surface 114 of the surface member 110 can be used as a mounting interface for the housing 120. In the perspective view of
[0071]
[0072]The outlets of the housing 120 (described in previous figures) face outward from under the front edge of the surface member 110, directed into the open space where a user would be situated. The base 190 provides the stability so that vibrations from the fluid flow generator within the housing 120 are dampened and not transmitted to the upper surface 112, thereby preventing disruptions to sensitive tasks such as writing or precision mouse movements. The rigid connection between the base 190 and the surface member 110, combined with the lightweight construction of the housing 120 (e.g., approximately 2.5 kilograms), can result in the center of gravity of the work surface remaining centered, preventing any tipping hazard even when the work surface is extended to its maximum height. Thus,
[0073]With reference to the figures, a temperature-controlled seat 200 will be described in accordance with example aspects of the present subject matter. As discussed in greater detail below, temperature-controlled seat 200 may include features for regulating the temperature in a workspace. The temperature-controlled seat 200 may define a vertical direction V, a lateral direction L, and a transverse direction T. The vertical direction V, the lateral direction L, and the transverse direction T may be mutually perpendicular and form an orthogonal direction system.
[0074]With reference to
[0075]
[0076]As shown in
[0077]Disposed within the base member 210 are one or more base member conduits 232. Further, disposed within the backrest member 220 are one or more backrest member conduits 234. These conduits 232, 234 form a closed-loop network configured to convey a thermal transfer fluid, such as water, glycol, or a specialized non-toxic thermal fluid, throughout the system. Further, the structure of the conduits 232, 234 can comprise a variety of materials including various plastics, silicone, flexible polymer, aluminum, and/or steel.
[0078]The arrangement of the conduits 232, 234 as depicted in
[0079]The one or more base member conduits 232 within the base member 210 can be configured to target specific anatomical zones. For example, the tubing pattern may be denser in the anterior region of the base member 210 to target the distal thighs, where femoral artery blood flow can effectively distribute absorbed heat to the rest of the body. In some embodiments, the conduits 232, 234 can be configured using flexible, tangle-resistant materials (e.g., medical-grade silicone tubing) with diameters and spacing that may improve thermal uniformity. The spacing between adjacent portions of the conduits may vary, for example, ranging from approximately 0.8 mm in high-intensity zones to 24.5 mm in peripheral zones, allowing for a granular gradient of thermal output.
[0080]The one or more backrest member conduits 234 within the backrest member 220 exhibit a distinct geometric configuration compared to the base member. As illustrated in
[0081]In some embodiments, the junction 202 can connect the base member 210 and the backrest member 220. The junction can be configured to route a continuous fluid path between the base member conduits 232 and the backrest member conduits 234 without restricting movement. The junction 202 may comprise a reinforced fabric section or a flexible polymer bellows that protects the tubing as it transitions between the horizontal plane of the seat and the vertical plane of the backrest. This flexibility can cause the flow of fluid to remain uninterrupted when a user alters the angle between the base member 210 and the backrest member 220 by reclining in the seat.
[0082]Although the active pumping and heating mechanisms can be housed in a separate enclosure (to be described in later figures),
[0083]The layout shown in
[0084]
[0085]The central base region 272 can be disposed along the longitudinal centerline of the base member 210, extending from the rear of the cushion toward the front. This region corresponds to the area of the seat that supports the user's thighs and the path of the femoral arteries. In the embodiment shown in
[0086]Flanking the central base region 272 are the intermediate base regions 274 and 275. Specifically, a first intermediate base region 274 is disposed on a left side of the central base region 272, and a second intermediate base region 275 is disposed on a right side. These regions generally correspond to the areas supporting the user's hips and outer buttocks. The physiological mapping utilized in the configuration of
[0087]Extending laterally outward from the intermediate base regions are the peripheral base regions 276 and 277. A first peripheral base region 276 defines the left lateral edge of the active thermal area, while a second peripheral base region 277 defines the right lateral edge. These zones provide structural support for the user's legs and hips but are less significant for active thermal regulation. In some embodiments, the conduit path may extend into these peripheral regions for edge-to-edge thermal consistency, but the fluid routing can be configured such that the fluid reaching these zones has already passed through the central and intermediate regions. Therefore, the fluid temperature in the peripheral base regions 276, 277 is naturally moderated (e.g., slightly cooler in heating mode or slightly warmer in cooling mode) due to the heat transfer that has already occurred upstream. This gradient approach prevents the user from feeling a sharp thermal contrast at the edges of the seat.
[0088]
[0089]The dashed lines in
[0090]Furthermore, the physical construction of the base member 210 in these zones may vary to support the tubing. The foam density in the central base region 272 can be selected to be slightly softer (e.g., closer to 36 kg/m3) to allow the tubing to conform closer to the user's body for maximum conduction, while the foam in the peripheral base regions 276, 277 might be higher density (e.g., closer to 42 kg/m3) to provide structural bolstering that prevents the tubing from collapsing under the weight of the user's legs.
[0091]
[0092]The fluid circuit within the backrest member 220 initiates and terminates at the central region 282, which can comprise a connection portion located at the bottom center of the backrest member 220. The connection portion of the central region 282 can be configured as a hydraulic interface between the backrest member 220 and the junction 202 (shown in
[0093]Extending vertically is the central backrest region 282. The central backrest region can be configured to align with a user's spinal column. As depicted in
[0094]Flanking the upper portion of the central backrest region 282 are the upper backrest regions 287 and 288. These regions are positioned to align with the user's scapula and the Teres Major and Teres Minor muscles. The routing of the conduits 234 in the upper backrest regions 287, 288 is specifically configured to deflect below the deltoids. This configuration choice can accommodate a user's expected posture. For example, when a user is typing or working at a work surface, they may roll their shoulders forward, which can reduce contact between the deltoids and the backrest. Therefore, routing fluid to the far outer edges of the upper backrest would be thermally inefficient. Instead, the conduits 234 in regions 287 and 288 concentrate thermal transfer on the Teres muscle groups where contact is maintained, which may result in efficient conductive heating or cooling. The tubing density in these regions can be moderate, balancing comfort with thermal intensity.
[0095]Below the upper backrest regions are the intermediate backrest regions 285 and 286, located on the right and left sides of the backrest member 220, respectively. These regions correspond to the area surrounding the user's kidneys. The kidneys are a region of high thermal transfer efficiency due to their role in filtering blood and their proximity to the body's core. The conduits 234 within the intermediate backrest regions 285, 286 form a contracted pattern, which can increase the linear density of the tubing to increase the surface area in contact with the user's mid-back region. Targeting the kidney area is particularly effective for raising the user's core body temperature in cold environments. For example, a user entering a cold office from the outdoors will feel a rapid restoration of thermal comfort as the warm fluid circulates through the intermediate backrest regions 285, 286, radiating warmth into the retroperitoneal space.
[0096]Continuing downward, the conduits 234 extend into the lower backrest regions 283 and 284. The spacing of the conduits 234 in the lower backrest regions 283, 284 can be configured to prevent a user from feeling the texture of the tubing through the padding. For example, the tubing spacing can be widened to approximately 24.5 mm in these high-contact zones to result in a smooth tactile experience while still providing a “heat belt” effect that soothes lower back tension.
[0097]Further, the lower boundary region 289 defines the bottom edge of the active thermal area, situated just above the central backrest region 282. This region can be below the lumbar support curve and has less contact with the user. Consequently, the conduits 234 in the lower boundary region 289 are primarily functional routing paths rather than active heat transfer zones. They serve to return the fluid from the peripheral loops of regions 283, 284, 285, and 286 back to the return manifold in the central backrest region 282.
[0098]The integrated configuration of the backrest member 220 shown in
[0099]
[0100]The base member 210 can be disposed horizontally along the seat pan of the chair base 290, while the backrest member 220 extends vertically along the chair's back support. To maintain the ergonomic integrity of the underlying chair, the base member 210 and backrest member 220 can be configured to have a specific thickness, for example, between 1.0 centimeters and 6.0 centimeters, utilizing high-density foam (e.g., 36 kg/m3 to 42 kg/m3). This thickness is sufficient to encapsulate the internal fluid conduits described in previous figures without creating bulk that would push the user too far forward on the seat or distort the lumbar support curve. For example, the side profile shows how the backrest member 220 maintains contact with the chair's back structure, which can cause the thermal transfer zones to align correctly with the user's spinal and lumbar regions without introducing uncomfortable gaps.
[0101]Suspended beneath the seat pan of the chair base 290 is the controller 260. The controller 260 can be configured to be the operational hub of the temperature-controlled seat 200, housing the heavier and bulkier components such as the fluid flow generator 250 (e.g., a pump that can circulate fluid through the conduits 232, 234), the fluid reservoir, the temperature regulation device 240 (e.g., a thermoelectric device such as a Peltier module, or a resistive heater), and the power source (battery). The fluid flow generator 250 can comprise one or more motors that can be configured to circulate, transport, and/or convey fluid through the conduits 232, 234. The fluid flow generator 250 can be electrically powered and can comprise a battery that can be used as a power source for the fluid flow generator 250. By centralizing these components in the controller 260 underneath the seat, the system keeps the user-contact surfaces (members 210, 220) soft, pliable, and free of hard mechanical parts.
[0102]The control interface 261 can be used to regulate the temperature of the fluid in the conduits 232, 234. For example, the control interface 261 can comprise a nob, dials, and/or buttons that can be used to modify the temperature of the fluid in the conduits 232, 234.
[0103]The controller 260 can have dimensions that fit within the footprint of chair mechanisms. In the side view of
[0104]An umbilical or bundled conduit connector extends from the output ports of the controller 260 to the input manifolds of the base member 210 and backrest member 220. This connection is configured with sufficient slack and flexibility to accommodate the articulation of the chair. For example, if the user leans back, causing the angle between the seat and backrest to open, the connecting tubing flexes without tangling or disconnecting. The fluid flow generator located within the controller 260 can drive the fluid up against gravity into the backrest member 220 and circulates it through the base member 210.
[0105]The internal configuration of the controller 260, can be configured to facilitate active thermal management. The enclosure may include intake and exhaust outlets on its lateral or posterior faces to allow for airflow across an internal heat exchanger or radiator. In cooling modes, where the system utilizes passive cooling by circulating ambient-temperature fluid, the heat absorbed from the user's body is transported to the controller 260. Here, a fan within the enclosure draws ambient air in (e.g., from the relatively cooler air mass near the floor) and passes it over the radiator to dissipate the heat before the fluid is recirculated to the cushions. The positioning shown in
[0106]Furthermore, the side view highlights the power management integration. The controller 260 can comprise a rechargeable battery pack (e.g., a lithium-ion array, a lithium iron phosphate battery, or a silicone battery) that can provide energy for the pump and heating elements. The location of the battery within the controller 260 can allow for easy access for charging or for swapping battery units. This wireless capability, enabled by the on-board power source allows the chair to remain mobile on its casters without being tethered to a wall outlet by a power cord.
[0107]The junction between the base member 210 and the backrest member 220 can act as a flexible hinge. In the side view, this junction conforms to the vertex of the chair. The materials chosen for the cover and the internal tubing (e.g., medical-grade silicone) allow the system to bend at this point repeatedly without fatigue. The side elevation confirms that the installation of the temperature-controlled seat 200 transforms the chair base 290 into a climate control station, delivering conductive heating or cooling to the user's entire posterior chain while maintaining the mechanical functionality and aesthetic silhouette of the original furniture.
[0108]
[0109]As depicted in
[0110]Although
[0111]The cover can be configured with a plurality of attachment points or straps. The straps can comprise webbing (e.g., cotton or nylon webbing) and may feature adjustable buckles or hook-and-loop fasteners. For example, a first set of straps may extend laterally from the backrest member 220 to wrap around the back of an office chair, while a second set of straps may extend from the base member 210 to secure underneath the seat pan. These attachment mechanisms are configured such that the temperature-controlled seat 200 moves in unison with the chair's own mechanics, including when the user reclines or adjusts the seat depth. Additionally, the cover may include a zipper or closure mechanism, which can be located on the rear or underside of the unit (not visible in the top plan view but integral to the cover assembly). This zipper allows for the insertion and removal of the internal foam and tubing assembly. This modularity can facilitate maintenance. For example, if the cover becomes soiled, the internal electronics and fluidics can be removed, allowing the fabric cover to be dry-cleaned or replaced without discarding the entire system.
[0112]
[0113]Further, the top plan view of
[0114]
[0115]The foundation of the assembly is the chair base 290, which provides stability and mobility for the system. In the embodiment depicted, the chair base 290 is a five-star pedestal equipped with casters, allowing the temperature-controlled seat 200 to be mobile within the workspace. The chair base 290 supports a central column, which can comprise a pneumatic height adjustment cylinder. This structural arrangement can be configured to function independently of the chair's position. For example, if the chair base 290 is rolled to a different part of the office or the height is adjusted, the thermal regulation components can move together with the user.
[0116]Supported by the central column is the chair seat structure 294. The chair seat structure 294 defines the horizontal platform upon which the base member 210 rests. In this perspective view, the base member 210 is shown conforming to the contours of the chair seat structure 294, covering the area where a user's buttocks and thighs would be positioned. The base member 210 can be secured to the chair seat structure 294 via a mounting interface, which may include a system of adjustable straps, tensioning buckles, or a non-slip friction layer on the underside of the base member 210. For example, the base member 210 may feature lateral straps that wrap around the underside of the chair seat structure 294, to prevent the cushion from sliding forward when the user sits down or shifts weight. The material of the base member 210, as visible in
[0117]Extending vertically from the rear of the chair seat structure 294 is the chair backrest 296. The chair backrest 296 provides the rigid or semi-rigid support frame for the backrest member 220. As illustrated, the backrest member 220 is mounted against the anterior face of the chair backrest 296, positioned to align with the user's lumbar and thoracic regions. The backrest member 220 is physically coupled to the base member 210 at the junction point (the vertex of the seat), creating a continuous thermal mat that hinges to match the recline angle of the chair backrest 296. The attachment of the backrest member 220 to the chair backrest 296 may also be achieved via strapping or an elasticized sleeve that fits over the top of the chair backrest 296. This configuration can cause the thermal zones (e.g., spinal and kidney heating zones) to remain correctly positioned relative to the user's anatomy even as the chair backrest 296 flexes and/or tilts.
[0118]The controller 260, can function as the central command and power unit for the temperature-controlled seat 200. The controller 260 can be connected to the base member 210 and backrest member 220 via a junction (e.g., bundled umbilical or fluid harnesses). This harness transports the thermal fluid from the reservoir and pump within the controller 260, up into the serpentine conduits of the cushions, and back again for recirculation. The placement of the controller 260 directly beneath the chair seat structure 294 reduces the length of tubing required, thereby reducing thermal loss in the transfer lines and improving the overall efficiency of the system. Additionally, the controller 260 can house a power source (e.g., lithium-ion battery array). This on-board power solution can improve mobility because the power source travels with the chair, the user is not tethered to a wall outlet by a power cord, allowing for 360-degree rotation and free movement across the floor on the chair base 290.
[0119]The controller 260 can also comprise an interface for thermal management logic. It may include external outlets or a fan exhaust port to facilitate the dissipation of heat when the system is operating in a cooling mode (where the fluid absorbs body heat and rejects it at the controller level) or to cool the internal electronics during high-intensity heating modes. The mounting of the controller 260 to the chair seat structure 294 is configured to be robust, utilizing mounting points or brackets that can withstand the vibrations of the pump and the dynamic forces of the chair moving. In some embodiments, the controller 260 includes a user-accessible control interface 261 and/or charging port on its side, allowing the user to easily recharge the system or make manual adjustments to the thermal settings if a remote interface is not being used. For example, the control interface 261 can be used to change the temperature of the base member 210 and/or the backrest member 220.
[0120]The temperature-controlled seat 200 can transform a passive chair into an active climate control device. For example, when a user sits on the base member 210, presence sensors located within the cushion (and wired to the controller 260) can detect the user sitting on the base member 210. The controller 260 can then activate the fluid flow generator to circulate fluid through the conduits in the base member 210 and backrest member 220. The heat can be transferred conductively to the user's body through the wool-blend cover of the members, while the mechanical noise of the pump is dampened by the mass of the controller 260 and its location under the seat. This configuration can provide a personalized thermal envelope that addresses the specific comfort needs of the user without altering the fundamental ergonomics or mechanical function of the office chair. In some embodiments, the temperature-controlled seat 200 can be fully integrated into a chair, sofa, divan, stool, armchair, loveseat, recliner, bench, seating apparatus, and/or other body support structure. For example, the temperature-controlled seat system 100 can be built into an office chair or a recliner.

[0122]Encapsulating the base foam 295 is the base cover 293. The base cover 293 is the exterior textile interface shown in
[0123]Extending upward from the rear of the base assembly is the backrest foam 299. Similar to the base component, the backrest foam 299 can provide the structural substrate for the vertical portion of the temperature-controlled seat 200. As illustrated in

[0163]In some examples, the controller can be configured, based on an input, to cause the temperature regulation device to modify a temperature of the fluid to a range of 1 degree Celsius to 2 degrees Celsius above the ambient temperature.
[0164]The disclosed technology provides a wide variety of technical effects and benefits. In particular, the temperature-controlled work surface system provides a personalized microclimate solution that enables localized thermal regulation directly at the user's workspace. A primary technical benefit is derived from the split-flow conduit configuration disposed within the housing, which creates distinct upper and lower airflow paths. The upper conduits can be configured to direct air substantially parallel to the lower surface of the work member, effectively targeting the user's torso. Simultaneously, the lower conduits are oriented at an angle that directs air downward toward the user's legs and feet. This dual-vector architecture provides effective thermal coverage regardless of whether the user is seated or using a standing desk, as the downward trajectory bridges the increased vertical distance to the lower limbs in a standing position.
[0165]The temperature-controlled work surface system enables precise user customization through a diverter control device, which allows the modulation of airflow ratios between 100% forward flow, 100% downward flow, or a blended mix, adapting to specific comfort needs. Internally, the conduits utilize toroid and/or serpentine geometries to maintain air pressure and velocity, which allows the air flow to reach the user with sufficient force for convective heating or cooling without generating distracting acoustic noise. The integration of Positive Temperature Coefficient (PTC) thermistors offers self-regulating safety benefits and rapid heating, while the airflow generated by the fluid flow generator actively cools internal electronics before expelling the conditioned air, thereby enhancing overall energy efficiency. Additionally, the system draws air from a rear intake to utilize cooler ambient air from beneath the work surface, preventing the recirculation of treated air and directing intake noise away from the user.
[0166]The temperature-controlled seat utilizes a fluid circulation system to deliver targeted conductive heat transfer, which is highly efficient for regulating body temperature. The disclosed technology utilizes a fluid medium with high specific heat capacity to create a stable thermal reservoir. This fluid results in rapid, uniform heat distribution, eliminating hot spots and accelerating the user's perception of a comfortable temperature (e.g., a target temperature of 43 degrees Celsius). The system features a sophisticated zonal mapping of conduits based on human physiology, enhancing thermal effectiveness. In the base member, conduits are arranged with high density (e.g., 0.6 mm to 1.0 mm spacing) in the central region to target femoral arteries, facilitating rapid systemic warming via blood circulation. Similarly, the backrest member features vertical conduit runs aligned with the spine and dense looping patterns near the kidneys to maximize heat transfer to core areas with high vascularity. In contrast, intermediate and peripheral regions utilize wider conduit spacing to provide a diffuse thermal gradient, which can prevent the formation of uncomfortable “hot spots” or localized perspiration.
[0167]The temperature-controlled seat offers versatile operation, including a passive cooling mode where the fluid flow generator circulates ambient-temperature fluid to absorb body heat and transport it to a controller for dissipation. The integration of a flexible junction between the base and backrest members means that the fluid path remains continuous and is not constricted during chair articulation, such as when a user reclines. The use of high-density foam (e.g., 36 kg/m3 to 42 kg/m3) creates a suspension matrix that prevents conduit collapse under user weight while masking the tactile presence of the conduits and providing improved ergonomic support. The temperature-controlled seat can include presence sensors that automatically deactivate thermal functions when the seat is unoccupied, significantly improving energy conservation. Furthermore, the integration of a battery power source within the under-seat controller allows the chair to remain fully mobile on its casters, obviating the need for tethered power cords.
