Description

Technical Field

[0002] With the digital transformation of office work, the average working person spends 6-8 hours a day sitting, and maintaining a fixed posture for a long time has become a core cause of muscle health problems. When sitting for long periods, the muscles of the waist, back, and buttocks bear a continuous static load, slowing down blood circulation. Initially, this manifests as muscle stiffness and soreness, and in the long term, it may lead to lumbar muscle strain, cervical spine degeneration, and there is also a potential risk of deep vein thrombosis. Especially when sitting for long periods and lacking activity, the blood in the lower limb veins stagnates, significantly increasing the probability of thrombosis.

[0003] As a core piece of equipment used by working professionals, the design of office chairs directly impacts the health benefits of prolonged sitting. While some mainstream office chairs currently offer basic massage functions, they suffer from a key flaw: massage can only be activated manually in fixed modes, failing to recognize the user's posture and duration of sitting. This results in a disconnect between massage timing and the body's fatigue level: either the massage activates before muscle fatigue sets in, causing interference, or it intervenes only after fatigue has developed, hindering preventative health management. Furthermore, existing massage functions often involve full-body vibration or broad-area pressure, lacking precise intervention for key areas of muscle stiffness and failing to consider the need for deep vein thrombosis prevention, thus failing to fundamentally address the health risks associated with prolonged sitting.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the embodiments of the present invention, they are protected by patent law.

Obviously, the described embodiments are only some embodiments of the embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the embodiments of the present invention.

[0025] In embodiments of the present invention, the words "exemplarily" or "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in embodiments of the present invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0026] The embodiments of the present invention can alleviate the continuous tension of the lumbar muscles by finely adjusting the backrest angle. The alternating inflation and deflation mode of the lumbar and calf airbag components can relieve back muscle stiffness and promote blood circulation in the lower limbs. The following is a detailed description in conjunction with the accompanying drawings.

[0027] Example 1

[0028] Please see Figure 1 As shown, Figure 1 This is a flowchart illustrating the sedentary fatigue intervention method disclosed in this invention. The execution entity of this invention includes software and hardware structures. The hardware structure mainly includes a controller, which can receive pressure signals sent by sensors, as well as backrest tilt angles, etc. The software mainly consists of control logic, such as setting preset parameters, comparing the collected parameters with the preset parameters, determining whether to activate the sedentary intervention mechanism, and the working mode of the sedentary intervention mechanism, etc. Please refer to... Figure 1 As shown, it may include the following steps: S110: In response to the activation of the sedentary intervention mechanism, receive the user's stress distribution data.

[0029] The sedentary intervention mechanism is activated under two conditions: the user is sitting in the seat and the mechanism is in a pending state, thus avoiding energy waste. There are various ways to detect whether the user is sitting in the seat. For example, a camera or infrared sensor can be installed on the seat. In a preferred embodiment of the present invention, a pressure sensor can be installed on the seat surface (cushion). When the pressure signal collected by the pressure sensor is greater than a preset pressure value, it is determined that there is someone in the seat. At the same time, the pressure sensor on the seat surface can also be used to collect the user's pressure distribution data.

[0030] The sedentary intervention mechanism can be put into a ready-to-trigger state by changing the working state of the controller. For example, the sedentary intervention mechanism can be put into a ready-to-trigger state by pressing a button or using voice control, or the controller can be in a standby state. When the system detects that the user is sitting in the seat, the sedentary intervention mechanism changes its state to a ready-to-trigger state.

[0031] The user's pressure distribution data is received through pressure sensors. To avoid misjudgment, in a preferred embodiment of the present invention, pressure sensor arrays are used on the backrest and seat surface respectively to collect the user's pressure distribution data, and then the variance is used to calculate the sitting posture stability coefficient.

[0032] For example, a pressure sensor array can be constructed by installing nine pressure sensors arranged in a 3x3 grid on both the backrest and the seat surface. The pressure sensors have a sensitivity of 0.01 kPa and a measurement range of 0-5 kPa. Data is collected in parallel at a sampling frequency of 10 Hz. When the controller receives the pressure distribution data, it preprocesses the data, including but not limited to: using a threshold method to remove abnormal data such as sensor malfunctions (e.g., pressure values ​​suddenly exceeding the 0-5 kPa range) and users temporarily getting up (pressure suddenly dropping to 0), to avoid misjudgment.

[0033] To prevent users from leaning forward while working and thus failing to collect pressure distribution data from the backrest, this embodiment of the invention also includes an adaptive adjustment mechanism for the backrest position to ensure that the backrest remains in contact with the corresponding parts of the human body. The adaptive adjustment structure for the backrest can adopt the technical means of Chinese invention patent application number 202411115488.2.

[0034] S120. Determine the sitting stability coefficient based on the pressure distribution data.

[0035] In a preferred embodiment of the present invention, by quantifying the postural stability coefficient as one of the criteria for judging a sedentary state, it is possible to effectively distinguish whether the user is in a stable sitting posture while focused on work or in a normal active state. This avoids the mechanical nature and misjudgment of traditional timed reminders, ensuring that intervention is only initiated when necessary, and laying the foundation for subsequent efficient and low-interference intervention.

[0036] The sitting posture stability coefficient can be determined by comparing the initial pressure distribution (preset pressure distribution data or measured pressure baseline data) with the pressure distribution data. Specifically, the sitting posture stability coefficient is quantified as the ratio of the variance of the pressure distribution over a continuous first preset time period (e.g., 10 seconds) to the variance of the initial pressure distribution.

[0037] Where K is the sitting posture stability coefficient. For the detection data of the i-th pressure sensor, This is the average value of the detection data from all pressure sensors. This refers to the preset pressure data or pressure reference data for the i-th pressure sensor. The average value of the preset pressure data or pressure reference data of all pressure sensors, where n is the total number of pressure sensors, 1≤i≤n.

[0038] When using preset pressure distribution data, the preset pressure data of the i-th pressure sensor and the average preset pressure data of all pressure sensors can be obtained through multiple trials by multiple users. This invention preferably uses pressure reference data to adapt to different users' body types and sitting postures. When using pressure reference data, after the sedentary intervention mechanism is activated, a reminder mechanism can remind the user to maintain their habitual office sitting posture and sit quietly for a second preset time. During this time, data collected from each pressure sensor is received, and the average value of the data collected from the i-th pressure sensor is used as the pressure reference data for the i-th pressure sensor.

[0039] S130. When the sitting posture stability coefficient is greater than or equal to the preset coefficient and the duration reaches the first preset time, it is determined to be a prolonged sitting state, and the prolonged sitting state is intervened by adjusting the backrest angle of the seat and / or the airbag pressure.

[0040] The determination of a prolonged sitting state is based on the following: when the sitting stability coefficient is greater than or equal to a preset coefficient, such as 0.8, the timing starts. When the timing reaches the first preset time, such as 45 minutes, it is determined to be a prolonged sitting state. If the user gets up during the timing period (pressure value ≤ 0.1 kPa for more than 2 seconds) or actively adjusts the posture (K < 0.8 for more than 5 seconds), the timing is reset and the timing starts again when the user's K ≥ 0.8.

[0041] In other embodiments, an angle sensor (such as an IMU) can be used to detect the backrest tilt angle. The change in the backrest tilt angle can help determine the prolonged sitting state. For example, if there is a large change in the backrest tilt angle during the timing period, and the duration of the changed tilt angle reaches more than 5 seconds, it is determined that the user has actively adjusted his sitting posture and the timing is reset.

[0042] In an office setting, to avoid interfering with other people, a gentle intervention approach is necessary. Specifically, one or more of the following methods can be used to achieve this: 1. Fatigue warning: A low-interference warning method is adopted, which activates a miniature buzzer to emit a low-volume warning sound for 1 second (≤30dB), and at the same time the seat's built-in vibration motor vibrates for 1 second to avoid disturbing nearby office workers; 2. Micro-adjustment program: The control adjustment mechanism (e.g., motor) drives the backrest angle to slowly and finely adjust from the initial value to the preset angle (e.g., within ±3° range) at the same angle change amount (e.g., 0.5° / s). The adjustment time is the third preset time (e.g., 10-20 seconds). By slightly changing the angle of force on the spine, it relieves the continuous tension of the lumbar muscles. The noise of the entire adjustment process is ≤25dB, which will not affect the user's work concentration or other office workers in the surrounding area. 3. Local airbag pulse intervention: Install an airbag assembly under the lumbar support or backrest corresponding to the user's waist, and install an airbag assembly on the front of the chair corresponding to the user's lower leg. By alternating the inflation and deflation of the two airbag assemblies, back muscle stiffness can be relieved and lower limb blood circulation can be promoted (preventing deep vein thrombosis). The airbag assembly includes an airbag and a pressure valve. The controller controls the inflation and deflation of the airbag by controlling the pressure valve. The inflation pressure is preferably controlled at 0.3-0.5 kPa (gentle pressure, no pressure sensation), with an inflation interval of 3 seconds and a single intervention lasting 5 minutes.

[0043] During the intervention, pressure and posture data are monitored in real time. If the user's pressure distribution data is less than the first preset pressure (e.g., 0.1 kPa, indicating that the user is getting up) and the duration is greater than the sixth preset time (e.g., 2 seconds), or / and the sitting stability coefficient is less than the preset coefficient (indicating that the user is adjusting their sitting posture) and the duration is greater than the seventh preset time (e.g., 5 seconds), the intervention is immediately paused and the sedentary duration timer is reset.

[0044] In other embodiments, the system can also automatically store the duration of each sedentary session, the intervention start time, and user posture feedback data (such as whether the posture was adjusted during the intervention) to form a user sedentary health log, which can provide data support for subsequent optimization of intervention parameters (such as adjusting the sedentary time threshold and sedentary stability threshold, and airbag pressure for different users).

[0045] Example 2

[0046] Please refer to Figure 2 As shown, a sedentary fatigue intervention system includes: a controller 210, an airbag assembly 220, an adjustment mechanism 230, a pressure sensor 240, and a mode storage unit 250. The airbag assembly 220 may include an airbag 221 and a pressure valve 2211 adapted to the airbag.

[0047] Pressure sensor 240 and controller 210 are connected via wired (I) 2 The controller 210 connects via USB (such as USB, C, etc.) or wireless (Bluetooth, WIFI, etc.), with a data transmission latency of ≤100ms. The controller 210 has a built-in microprocessor that communicates with the pattern storage unit 250. It can read the parameters of the intervention plan stored in the pattern storage unit 250, and can also write user-modified intervention plan parameters into the pattern storage unit 250.

[0048] The controller 210 receives pressure signals collected by the pressure sensor 240 (seat surface pressure sensor), and activates the prolonged sitting intervention mechanism based on the pressure signals and the trigger state of the mechanism. This involves receiving pressure distribution data of the user collected by the pressure sensor array 240 (including a backrest pressure sensor composed of multiple pressure sensors installed on the backrest and a seat surface pressure sensor array composed of multiple pressure sensors installed on the seat surface); and determining a posture stability coefficient based on the pressure distribution data. When the posture stability coefficient is greater than or equal to a preset coefficient and the duration reaches a first preset time, the system determines the state as prolonged sitting. The controller then adjusts the backrest tilt angle and / or the airbag pressure via the adjustment mechanism and the airbag assembly, thereby intervening in the prolonged sitting state.

[0049] Adjusting the backrest tilt angle of the seat through the adjustment mechanism includes: the controller driving the backrest tilt angle from the initial value to the preset angle by the same amount of angular change through the adjustment mechanism, the adjustment time being a third preset time, the preset angle including a positive preset angle and a negative preset angle.

[0050] The airbag assembly includes an airbag and a pressure valve. The airbag pressure is adjusted by the airbag assembly, including: the controller controls the airbags at the front of the seat to start an alternating inflation and deflation mode through the pressure valve to massage the user's waist and calves. The inflation pressure is controlled within a preset pressure range, the inflation interval is a fourth preset time, and the intervention duration is a fifth preset time.

[0051] This invention also provides a seat, which can be an office chair, a car seat, etc. The seat includes the above-mentioned sedentary fatigue intervention system and other necessary structures. The other necessary structures can adopt existing conventional technologies, which will not be described in detail here.
