Description

Technical Field

[0001] This invention relates to the field of ergonomic support technology, and in particular to a fatigue control method for providing ergonomic flexible support platforms, ergonomic flexible support platforms, and human body support equipment. Background Technology

[0002] When sitting for extended periods, the lower back, buttocks, and thighs, which provide support, experience prolonged pressure, hindering blood circulation in the soft tissues, leading to muscle hypoxia and the accumulation of metabolic waste products. This can easily cause numbness, soreness, stiffness, and other discomfort. As sitting time increases, if not adjusted promptly, microcirculatory damage gradually accumulates, potentially leading to chronic strain and even spinal problems. Currently, a common approach is to use massage devices such as massage chairs or massage machines to provide temporary relief after the user has experienced significant fatigue or discomfort. However, this method only addresses symptoms after they appear, representing a passive "post-treatment" approach. It cannot proactively intervene in the distribution of pressure during the pressure accumulation phase, nor can it prevent the occurrence and development of microcirculatory damage. Furthermore, while static support products (such as ordinary lumbar supports and memory foam cushions) provide initial comfort, their support remains constant, causing continuous pressure on the same area after prolonged use, thus failing to provide preventative benefits. Therefore, the known technologies generally lack the ability to dynamically adjust before user fatigue occurs. There is an urgent need for a preventative support solution that can proactively change the stress point and balance pressure during the support process, so as to truly reduce the health risks caused by prolonged sitting from the source.

The term "based on" means "at least partially based on." The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment," and so on.

[0028] Additionally, terms such as “first,” “second,” etc., may be used in this document for reference purposes only and are not intended to be limiting. For example, unless the context clearly indicates otherwise, the words “first,” “second,” and other such numerical terms relating to structures or elements do not imply order or sequence.

[0029] One embodiment of the present invention provides a fatigue control method applied to an ergonomic flexible support platform. Figure 2 As shown, the flexible support platform 1 includes multiple support areas 10, and the support force of each support area 10 can be adjusted independently.

[0030] The fatigue prevention control method of the present invention includes: executing a fatigue prevention program after the fatigue prevention triggering condition is reached. The fatigue prevention program includes: intermittently adjusting the support force of at least some of the multiple support areas 10 to alternately change the support pressure borne by the corresponding parts of the user, and actively intervening before the user feels fatigue and numbness to prevent the user's soft tissue from numbness and soreness caused by prolonged continuous pressure.

[0031] In one embodiment, such as Figure 3 As shown, each support region 10 is provided with at least one pressure regulating chamber 14. The pressure inside each pressure regulating chamber 14 is adjusted by adjusting the amount of filling material inside the chamber. The filling material inside the pressure regulating chamber 14 includes, but is not limited to, air, inert gas, water, or silicone.

[0032] Preferably, the pressure regulating chamber 14 is an air bladder, and the supporting force provided by the supporting region 10 is changed by adjusting the amount of gas contained in the air bladder.

[0033] In this embodiment, the flexible support platform 1 includes a controller, a pump body, electrically controlled valves, and pipelines. The pump body is connected to multiple pressure regulating chambers 14 via pipelines, and each pipeline is equipped with an electrically controlled valve to achieve independent control of each pressure regulating chamber 14.

[0034] The controller is electrically connected to the pump body and the electrically controlled valve. The controller controls the operation of the pump body and the electrically controlled valve to achieve intermittent adjustment of the support force of at least some of the multiple support areas 10.

[0035] In one embodiment, each support region 10 includes a telescopic support rod and a support panel. The position of the support panel is adjusted by driving the telescopic support rod to extend or retract, thereby enabling intermittent adjustment of the support force of at least some of the support regions 10.

[0036] In one embodiment, such as Figure 1 As shown, the fatigue control method of the present invention includes: Step S10: Check whether the flexible support platform meets the fatigue prevention triggering conditions.

[0037] In one embodiment, the anti-fatigue trigger condition is an anti-fatigue trigger command issued by the user. After the flexible support platform receives the anti-fatigue trigger command, it can determine that the flexible support platform has reached the anti-fatigue trigger condition, and then control the flexible support platform to execute the anti-fatigue program.

[0038] Optionally, users can issue anti-fatigue trigger commands via mobile terminals, which then wirelessly transmit the commands to the flexible support platform.

[0039] Optionally, the flexible support platform is equipped with a control panel, through which users can issue anti-fatigue trigger commands.

[0040] In one embodiment, when it is detected that the user has maintained the same posture for a preset period of time, it is determined that the anti-fatigue trigger condition has been met.

[0041] In this embodiment, the flexible support platform is equipped with a matrix of pressure sensors. The user's current posture can be determined by the status of the pressure sensors at different locations. In this embodiment, the matrix of pressure sensors monitors the user's current posture in real time and records the duration of the current posture.

[0042] Optionally, the preset duration can be a pre-set fixed value, a user-defined duration, or a duration dynamically calculated based on the user's historical data. This invention is not limited to a specific preset duration.

[0043] In one specific embodiment, the flexible support platform is a support device for the seat, and the method for determining the user's current posture is as follows: When the pressure sensor contact in the center of the seat cushion remains closed, and the pressure sensors in the area corresponding to the center of the lower back are also closed, and the dynamic change frequency of the pressure sensors is low, the user's current posture can be determined as "sitting upright". When the pressure sensor contact at the front of the seat cushion remains closed, and the pressure sensors in the area corresponding to the lower lower back are also closed, and the dynamic change frequency of the pressure sensors is low, the user's current posture can be determined as "leaning forward". When the pressure sensor contact at the rear of the seat cushion remains closed, and the pressure sensors in the area corresponding to the upper lower back are also closed, and the dynamic change frequency of the pressure sensors is low, the user's current posture can be determined as "leaning back". When all pressure sensor contacts are open for a certain duration (e.g., 3 seconds), the user's current posture can be determined as "leaning off the seat".

[0044] In one embodiment, if the force distribution on the user remains unchanged for a preset period of time, it is determined that the anti-fatigue trigger condition has been met.

[0045] In this embodiment, the flexible support platform is equipped with multiple pressure sensors to detect the stress on various areas corresponding to different parts of the user's body. When the pressure sensors detect that the stress on these areas has not changed within a preset time period, the fatigue prevention trigger condition is determined to have been met.

[0046] Step S20: After the anti-fatigue triggering condition is met, the anti-fatigue program is executed, and the support force of at least some of the support areas in multiple support areas is intermittently adjusted.

[0047] In one embodiment, step S20 includes: intermittently controlling the support force of some support areas in a preset sequence to decrease, and controlling the support force of the remaining support areas to remain unchanged and / or increase.

[0048] Optionally, the preset order is either from top to bottom or from bottom to top, based on the arrangement of multiple support areas; or the preset order is the order set by the user through the control panel on the mobile terminal or flexible support platform.

[0049] Optionally, intermittent refers to pausing the anti-fatigue program after it has run for a certain period of time, and then resuming the program; or intermittent refers to continuously executing the anti-fatigue program after the anti-fatigue trigger condition is met.

[0050] In this embodiment, the support force of one support region can be reduced at the same time, or the support force of multiple support regions can be reduced simultaneously. When reducing the support force of multiple support regions simultaneously, these multiple support regions can be adjacent support regions or non-adjacent support regions.

[0051] At the same time, the support force of the remaining support areas, excluding the support areas where the support force has decreased, is kept constant; or the support force of the remaining support areas is increased; or the support force of a portion of the remaining support areas remains constant while the support force of another portion of the remaining support areas is increased.

[0052] In one specific embodiment, the fatigue prevention procedure involves intermittently controlling the support force of the Nth support region among multiple support regions to decrease until the first support force reaches a preset duration, and controlling the support force of the remaining support regions to increase to the second support force and / or maintain at the initial support force.

[0053] The second supporting force is greater than the initial supporting force, while the first supporting force is less than the initial supporting force.

[0054] Optionally, the support force of the Nth support region is reduced to the first support force, while the support force of the remaining support regions is maintained at the initial support force. After a preset time is reached, the support force of the Nth support region is increased to the initial support force, and the support force of the (N+1)th support region is reduced to the first support force. The increase and decrease of the support force of the support regions are continuously controlled in a preset order until a preset period is reached.

[0055] Optionally, the support force of the Nth support region is controlled to decrease to the first support force, while the support force of the (N+1)th and / or (N-1)th support regions is controlled to increase to the second support force. The support force of the remaining support regions remains at the initial support force. After a preset time is reached, the support force of the Nth support region is controlled to increase to the initial support force or the second support force, the support force of the (N+1)th support region is controlled to decrease to the first support force, and the support force of the (N+2)th support region is controlled to increase to the second support force or remain at the initial support force. The increase and decrease of the support force of the support regions are continuously controlled according to a preset sequence until a preset period is reached.

[0056] In some embodiments, the flexible support platform is provided with at least one pressure regulating chamber. When the pressure in the pressure regulating chamber is the initial pressure value, the supporting force provided to the support area is the initial supporting force. It should be noted that the initial supporting force of each support area is the same, or the initial supporting force of each support area is different depending on the actual usage requirements.

[0057] When the pressure in the pressure regulating chamber is 30%-50% of the initial pressure, the supporting force provided to the support area is the first supporting force. When the pressure in the pressure regulating chamber is 110%-120% of the initial pressure, the supporting force provided to the support area is the second supporting force.

[0058] In some embodiments, the fatigue prevention control method further includes: receiving user-defined fatigue prevention parameters and executing a fatigue prevention program based on the fatigue prevention parameters. The fatigue prevention parameters include, but are not limited to, at least one of the following: adjustment amount of the support force in the support area, adjustment time of the support force in the support area, holding time of the support force in the support area, and cycle period.

[0059] The cycle period can be set according to time or according to the number of times the support force of the support area is adjusted; however, this invention is not limited to these settings.

[0060] In one embodiment, the fatigue prevention control method further includes: when the user adjusts the support position, controlling to pause the execution of the above-mentioned fatigue prevention program, and resuming the execution of the fatigue prevention program after the support position adjustment is completed.

[0061] In one embodiment, when the user adjusts the support position, the anti-fatigue procedure continues to be executed, and a new anti-fatigue procedure is executed based on the current support position after the support position adjustment is completed.

[0062] In this embodiment, the initial support force of the support area changes when the user adjusts the support position. Therefore, after the support position adjustment is completed, the anti-fatigue procedure is re-executed based on the current support position.

[0063] In one specific implementation, such as Figure 2 and Figure 3 As shown, the flexible support platform 1 includes three support areas 10, each containing an airbag. The three support areas 10 sequentially include a first support area 11, a second support area 12, and a third support area 13, corresponding to the upper waist area, middle waist area, and lower waist area of ​​the human body, respectively.

[0064] In the initial stage (i.e. when the anti-fatigue procedure is performed), the airbags in the first support area 11, the second support area 12 and the third support area 13 are all inflated to 10 mmHg (i.e., the initial pressure value).

[0065] After detecting that the user has maintained the same posture for 45 minutes, an anti-fatigue program is executed.

[0066] Specifically, fatigue prevention procedures include: Step 1: Deflat the airbag in the first support area 11 to 5 mmHg, inflate the airbag in the second support area 12 to 11 mmHg, and maintain the airbag in the third support area 13 at 10 mmHg for 45 seconds.

[0067] Step 2: Inflate the airbag in the first support area 11 to 10 mmHg, maintain the airbag in the second support area 12 at 11 mmHg, and deflate the airbag in the third support area 13 to 5 mmHg for 45 seconds.

[0068] Step 3: Control the airbag in the first support area 11 to maintain 10 mmHg, deflate the airbag in the second support area 12 to 5 mmHg, and inflate the airbag in the third support area 13 to 10 mmHg for 45 seconds.

[0069] Repeat steps 1-3 until the preset time is reached, or the number of times each support area is vented reaches the preset number.

[0070] In this embodiment, each support area 10 is deflated for 45 seconds in turn, so that the soft tissue of the corresponding body part is released while the remaining support areas 10 can still provide effective support, so as to avoid the user feeling a sudden change and being distracted when performing the anti-fatigue program.

[0071] According to an embodiment of the present invention, an ergonomic flexible support platform is provided, such as... Figure 4 The ergonomic flexible support platform 1 shown includes multiple support areas 10 and a control device 20.

[0072] The flexible support platform 1 includes multiple support areas 10, and the support force of each support area 10 can be adjusted independently.

[0073] In one embodiment, each support region 10 is provided with at least one pressure regulating cavity 14. The pressure inside each pressure regulating cavity 14 is adjusted by adjusting the amount of filling material inside the cavity. The filling material inside the pressure regulating cavity 14 includes, but is not limited to, air, inert gas, water, or silicone.

[0074] Preferably, the pressure regulating chamber 14 is an air bladder, and the supporting force provided by the supporting region 10 is changed by adjusting the amount of gas contained in the air bladder.

[0075] In this embodiment, the flexible support platform 1 includes a controller, a pump body, electrically controlled valves, and pipelines. The pump body is connected to multiple pressure regulating chambers 14 via pipelines, and each pipeline is equipped with an electrically controlled valve to achieve independent control of each pressure regulating chamber 14.

[0076] The controller is electrically connected to the pump body and the electrically controlled valve. The controller controls the operation of the pump body and the electrically controlled valve to achieve intermittent adjustment of the support force of at least some of the multiple support areas 10.

[0077] In one embodiment, each support region 10 includes a telescopic support rod and a support panel. The position of the support panel is adjusted by driving the telescopic support rod to extend or retract, thereby enabling intermittent adjustment of the support force of at least some of the support regions 10.

[0078] The control device 20 is configured to execute an anti-fatigue program after the anti-fatigue trigger condition is met. The anti-fatigue program includes: intermittently adjusting the support force of at least some of the multiple support areas 10 to alternately change the support pressure borne by the corresponding parts of the user, and actively intervening before the user feels fatigued and numb, so as to prevent the user's soft tissue from becoming numb and sore due to prolonged continuous pressure.

[0079] In one embodiment, such as Figure 4 As shown, the control device 20 includes a pressure distribution adjustment module 200, configured to detect whether the flexible support platform 1 has reached the anti-fatigue trigger condition; after reaching the anti-fatigue trigger condition, it executes an anti-fatigue program to intermittently adjust the support force of at least some of the support areas 10 among the multiple support areas 10.

[0080] In one embodiment, the anti-fatigue trigger condition is an anti-fatigue trigger command issued by the user. After the flexible support platform 1 receives the anti-fatigue trigger command, it can be determined that the flexible support platform 1 has met the anti-fatigue trigger condition, and then the flexible support platform 1 is controlled to execute the anti-fatigue program.

[0081] Optionally, the user can issue an anti-fatigue trigger command via a mobile terminal, which then sends the anti-fatigue trigger command to the flexible support platform 1 via wireless transmission.

[0082] Optionally, the flexible support platform 1 is equipped with a control panel, through which users can issue anti-fatigue trigger commands.

[0083] In one embodiment, when it is detected that the user has maintained the same posture for a preset period of time, it is determined that the anti-fatigue trigger condition has been met.

[0084] In this embodiment, the flexible support platform 1 is equipped with a matrix of pressure sensors. The user's current posture can be determined by the status of the pressure sensors at different locations. In this embodiment, the matrix of pressure sensors monitors the user's current posture in real time and records the duration of the user's current posture.

[0085] Optionally, the preset duration can be a pre-set fixed value, a user-defined duration, or a duration dynamically calculated based on the user's historical data. This invention is not limited to a specific preset duration.

[0086] In one specific embodiment, the flexible support platform 1 is a flexible support device for the seat, and the method for determining the user's current posture is as follows: When the pressure sensor contact in the center of the seat cushion remains closed, and the pressure sensors in the area corresponding to the center of the lower back are also closed, and the dynamic change frequency of the pressure sensors is low, the user's current posture can be determined as "sitting upright". When the pressure sensor contact at the front of the seat cushion remains closed, and the pressure sensors in the area corresponding to the lower lower back are also closed, and the dynamic change frequency of the pressure sensors is low, the user's current posture can be determined as "leaning forward". When the pressure sensor contact at the rear of the seat cushion remains closed, and the pressure sensors in the area corresponding to the upper lower back are also closed, and the dynamic change frequency of the pressure sensors is low, the user's current posture can be determined as "leaning back". When all pressure sensor contacts are open for a certain duration (e.g., 3 seconds), the user's current posture can be determined as "leaning off the seat".

[0087] In one embodiment, if the force distribution on the user remains unchanged for a preset period of time, it is determined that the anti-fatigue trigger condition has been met.

[0088] In this embodiment, the flexible support platform 1 is equipped with multiple pressure sensors to detect the stress on various areas corresponding to different parts of the user's body. When the pressure sensors detect that the stress on these areas has not changed within a preset time period, the fatigue prevention trigger condition is determined to have been met.

[0089] In one embodiment, the pressure distribution adjustment module 200 is configured to intermittently control the support force of some of the multiple support regions 10 to decrease according to a preset sequence, while controlling the support force of the remaining support regions 10 to remain unchanged and / or increase.

[0090] Optionally, the preset order is either from top to bottom or from bottom to top according to the arrangement of the multiple support areas 10; or the preset order is the order set by the user through the control panel on the mobile terminal or the flexible support platform 1.

[0091] Optionally, intermittent refers to pausing the anti-fatigue program after it has run for a certain period of time, and then resuming the program; or intermittent refers to continuously executing the anti-fatigue program after the anti-fatigue trigger condition is met.

[0092] In this embodiment, the support force of one support region 10 can be reduced at the same time, or the support force of multiple support regions 10 can be reduced simultaneously. When the support force of multiple support regions 10 is reduced simultaneously, the multiple support regions 10 can be adjacent support regions or non-adjacent support regions.

[0093] At the same time, the support force of the remaining support area 10, excluding the support area 10 with reduced support force, is kept unchanged; or the support force of the remaining support area 10 is increased; or the support force of a part of the remaining support area 10 remains unchanged, while the support force of another part of the support area 10 is increased.

[0094] In one specific embodiment, the fatigue prevention procedure is to intermittently control the support force of the Nth support region 10 among multiple support regions 10 to decrease until the first support force reaches a preset duration according to a preset sequence, and control the support force of the remaining support regions 10 to increase to a second support force and / or maintain at the initial support force.

[0095] The second supporting force is greater than the initial supporting force, while the first supporting force is less than the initial supporting force.

[0096] Optionally, the support force of the Nth support region 10 is controlled to decrease to the first support force, while the support force of the remaining support regions 10 is controlled to remain at the initial support force. After a preset time is reached, the support force of the Nth support region 10 is controlled to increase to the initial support force, and the support force of the (N+1)th support region 10 is controlled to decrease to the first support force. The increase and decrease of the support force of the support regions 10 are continuously controlled in a preset order until a preset cycle is reached.

[0097] Optionally, the support force of the Nth support region 10 is controlled to decrease to the first support force, while the support force of the (N+1)th and / or (N-1)th support regions 10 is controlled to increase to the second support force. The support force of the remaining support regions 10 is maintained at the initial support force. After a preset time is reached, the support force of the Nth support region 10 is controlled to increase to the initial support force or the second support force, the support force of the (N+1)th support region 10 is controlled to decrease to the first support force, and the support force of the (N+2)th support region 10 is controlled to increase to the second support force or remain at the initial support force. The increase and decrease of the support force of the support regions 10 are continuously controlled according to a preset sequence until a preset cycle is reached.

[0098] In some embodiments, the flexible support platform 1 is provided with at least one pressure regulating cavity 14. When the pressure value in the pressure regulating cavity 14 is the initial pressure value, the supporting force provided to the support area 10 is the initial supporting force. It should be noted that the initial supporting force of each support area 10 is the same, or the initial supporting force of each support area 10 is different depending on the actual usage requirements.

[0099] When the pressure value inside the pressure regulating chamber 14 is 30%-50% of the initial pressure value, the supporting force provided to the supporting area 10 is the first supporting force. When the pressure value in the pressure regulating chamber 14 is 110%-120% of the initial pressure value, the supporting force provided to the supporting area 10 is the second supporting force.

[0100] In some implementations, such as Figure 4 As shown, the ergonomic flexible support platform also includes a parameter configuration module 202, configured to receive user-defined anti-fatigue parameters and execute an anti-fatigue program based on these parameters. The anti-fatigue parameters include, but are not limited to, at least one of the following: adjustment amount of the support force of the support area 10, adjustment time of the support force of the support area 10, holding time of the support force of the support area 10, and cycle period.

[0101] The cycle period can be set according to time or according to the number of times the support force of the support area 10 is adjusted. This invention is not limited to these limitations.

[0102] In one embodiment, the control device 20 is configured to: when it detects that the user has adjusted the support position, control to pause the execution of the above-mentioned anti-fatigue program, and resume the execution of the anti-fatigue program after the support position adjustment is completed.

[0103] In one embodiment, the control device 20 is configured to: continue executing the anti-fatigue program when it detects that the user has adjusted the support position, and execute a new anti-fatigue program based on the current support position after the support position adjustment is completed.

[0104] In this embodiment, the initial support force of the support area 10 changes when the user adjusts the support position. Therefore, after the support position adjustment is completed, the anti-fatigue procedure is re-executed based on the current support position.

[0105] In one specific implementation, such as Figure 2 and Figure 3 As shown, the flexible support platform 1 includes three support areas 10, each containing an airbag. The three support areas 10 sequentially include a first support area 11, a second support area 12, and a third support area 13, corresponding to the upper waist area, middle waist area, and lower waist area of ​​the human body, respectively.

[0106] In the initial stage (i.e. when the anti-fatigue procedure is being executed), the control device 20 controls the airbags in the first support area 11, the second support area 12 and the third support area 13 to be inflated to 10 mmHg (i.e., the initial pressure value).

[0107] After detecting that the user has maintained the same posture for 45 minutes, the control device 20 executes the anti-fatigue program.

[0108] Specifically, fatigue prevention procedures include: Step 1: Deflat the airbag in the first support area 11 to 5 mmHg, inflate the airbag in the second support area 12 to 11 mmHg, and maintain the airbag in the third support area 13 at 10 mmHg for 45 seconds.

[0109] Step 2: Inflate the airbag in the first support area 11 to 10 mmHg, maintain the airbag in the second support area 12 at 11 mmHg, and deflate the airbag in the third support area 13 to 5 mmHg for 45 seconds.

[0110] Step 3: Control the airbag in the first support area 11 to maintain 10 mmHg, deflate the airbag in the second support area 12 to 5 mmHg, and inflate the airbag in the third support area 13 to 10 mmHg for 45 seconds.

[0111] Repeat steps 1-3 until the preset time is reached, or the preset number of deflations is reached for each support area.

[0112] In this embodiment, each support area 10 is deflated for 45 seconds in turn, so that the soft tissue of the corresponding body part is released while the remaining support areas 10 can still provide effective support, so as to avoid the user feeling a sudden change and being distracted when performing the anti-fatigue program.
