Description

Technical Field

[0001] This invention relates to the field of smart pillow technology, specifically to an adaptive adjustment method for a head, neck, and body integrated pillow. Background Technology

[0002] Sleep health is an important component of overall health. As a core sleep aid, the pillow's height, support, and compatibility with the body's sleeping posture and spinal curvature directly affect the physiological state of the cervical and lumbar spine, thus determining sleep quality and spinal health. Traditional pillows are mostly of fixed height, unable to adapt to the different height needs of the two core sleeping postures of back and side sleeping, and even less able to provide dynamic support for the lumbar region.

[0003] When sleeping on your back, the cervical spine naturally curves forward, requiring a lower pillow height. Simultaneously, the lumbar region needs adequate support to fill the gap between the lumbar spine and the bed surface. When sleeping on your side, the support of the shoulder width necessitates a higher pillow height, while the lumbar region needs slightly lower support to avoid excessive lumbar support. Using a fixed-height pillow can easily lead to the cervical spine being unsupported and the lumbar region lacking support when sleeping on your back, and the head tilting and the lumbar region being compressed when sleeping on your side. Long-term use of such pillows can easily cause cervical strain, lumbar discomfort, and frequent tossing and turning during sleep.

[0004] To address these issues, some height-adjustable smart pillows have emerged on the market. These typically use an air pump to inflate and deflate air bladders to achieve height adjustment and pressure sensors to detect changes in sleeping posture. However, they generally suffer from the following shortcomings: First, they lack coordinated adjustment for lumbar support, failing to achieve integrated head-neck-lumbar spinal alignment; second, their air pressure control precision is low, lacking a closed-loop feedback mechanism based on multimodal sensing; and third, they lack mechanisms for personalized user learning, height memory, and closed-loop analysis and feedback of sleep data, resulting in simplistic control logic, poor adjustment precision, and a subpar user experience, failing to meet users' needs for a precise, comfortable, and intelligent sleep experience and spinal health protection. Summary of the Invention

[0005] This invention is implemented as follows: an adaptive adjustment method for an integrated head, neck, and body pillow, the integrated head, neck, and body pillow having TPU airbags and a control system, wherein the TPU airbags include a head airbag unit, a neck airbag unit, and a lumbar airbag unit; the adaptive adjustment method includes the following steps: S100: Collect multimodal pressure distribution signals of the human head, neck and waist through a sensor sensing layer set in the occipital region of the body; S200. Identify the user's current sleeping position based on the pressure distribution signal, wherein the sleeping position includes sleeping on the back, sleeping on the left side, and sleeping on the right side; S300: Based on the identified current sleeping posture, inflate or deflate the head airbag unit, neck airbag unit, and lumbar airbag unit of the TPU airbag, and adjust the height of the corresponding sections of the head and body occipital regions to achieve neutral spinal alignment.

[0006] Furthermore, the steps for identifying the user's current sleeping position based on the pressure distribution signal specifically include: S210. Obtain pressure values ​​from multiple collection points in the sensor sensing layer, including the fossa region, the side-sleeping support area, the shoulder and neck support area, and the left, middle, and right lumbar regions, collected by the array pressure sensor. S220. Compare the pressure value with the pre-stored supine sleeping pressure distribution template, left-side sleeping pressure distribution template, and right-side sleeping pressure distribution template in the memory; S230. Determine the current sleeping position based on the comparison results.

[0007] Furthermore, the comparison logic in step S220 includes: Calculate the similarity distance D between the real-time pressure feature vector and the pre-stored template vector; When the user makes a manual adjustment, the system marks the current real-time pressure feature vector as a calibration feature and updates the preset height parameter of the corresponding sleeping position according to the height value of the manual adjustment. A manual intervention weighting factor α (0.5 < α < 1) is introduced. In the next identification and comparison, if the similarity between the real-time signal and the calibration feature reaches the preset threshold, the manually adjusted height parameter will be used as the adjustment target.

[0008] Furthermore, a user preference feature library is established in the memory to record the frequency and value of manual adjustments made by the user for different sleeping positions. When the system detects that the user has manually adjusted the height to be consistent N times for the same sleeping position, the system automatically overwrites the original preset height with the consistent height value, thereby achieving closed-loop optimization of the sleeping position recognition and height adjustment algorithm; N is 3 to 10 times.

[0009] Furthermore, it also includes the following steps: S000, Initial Learning: S010. In response to the user's first use or learning instruction, prompt the user to maintain the preset sleeping positions of supine, left side and right side in sequence and stay for a preset time. S020. Collect the pressure distribution signals of the sensor sensing layer under each preset sleeping position, generate the back sleeping pressure distribution template, left side sleeping pressure distribution template and right side sleeping pressure distribution template corresponding to the user, and store them in the memory.

[0010] Furthermore, the adjustment logic in step S300 specifically includes: When the patient is identified as sleeping on their back, the lumbar airbag unit is inflated to raise the lumbar support height, the head airbag unit is deflated to lower the head pillow height, and the neck airbag unit is adjusted to a preset height that matches the patient's back position to fill the gap in the cervical curve and maintain the natural physiological curvature of the cervical spine. When the user is identified as sleeping on their side, the lumbar airbag unit is deflated to lower the lumbar support height, the head airbag unit is inflated to raise the head pillow height, and the neck airbag unit is adjusted to a preset height that matches the side sleeping position to provide stable neck support.

[0011] Furthermore, step S300 also includes air pressure closed-loop control: By using air pressure sensors installed in the sensor sensing layer, the air pressure value inside each airbag unit is monitored in real time, and the air pressure signal is fed back to the control system. The control system compares the measured air pressure value with the target air pressure value and adjusts the opening degree of the control valve and the working state of the air pump through a closed-loop algorithm until the actual air pressure value reaches the target range.

[0012] Furthermore, it also includes manual adjustment control: In response to the user's height adjustment command via mobile terminal device, the airbag units of the TPU airbag are inflated or deflated to adjust to the height specified by the user. The user-specified height is stored in the memory as the preset height corresponding to the sleeping position; The system retrieves the user-specified height stored in memory and controls the air pump to adjust the airbag unit to that height.

[0013] Furthermore, this also includes preference learning and adaptive model optimization: When a user manually fine-tunes the height of the headrest or body pillow via a mobile terminal device, the control system records the user's adjustment behavior, adjustment range, and corresponding posture environment. When the system detects that the same user is making the same adjustment repeatedly during multiple sleep cycles, it automatically determines that the user's physiological curvature has a specific support requirement, updates the user's corresponding body type-support weight factor, and adds the corresponding height compensation amount in the subsequent automatic adjustment process. Through multiple perception-feedback cycles, the system gradually learns a personalized sleep model for each user.

[0014] Furthermore, it also includes steps for sleep data monitoring and report generation: During the user's sleep, the control system of the head, neck and body integrated pillow collects pressure distribution signals through the array pressure sensors in the sensor sensing layer, and collects micro-motion signals through the piezoelectric sensor strip in the sensor sensing layer. The micro-motion signals include breathing fluctuations, heart rate fluctuations and acceleration impacts when turning over. The control system records the user's supine sleeping time, side sleeping time, number of times the user is out of bed, number of times the user turns over, heart rate, breathing, and total sleep duration based on the collected signals, and generates a sleep report based on the recorded data. The sleep report includes daily, weekly, and monthly reports, and contains sleep scores, sleep analysis data, and report interpretation. The control system sends sleep reports to the user's mobile terminal device via a wireless communication unit, allowing the user to view them in the corresponding control APP or WeChat mini-program.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention relies on the array pressure sensor and piezoelectric sensor belt inside the pillow to collect multimodal pressure distribution signals of the human head, neck and waist and identify the corresponding sleeping posture. Then, according to the identification results, it controls each unit of the internal TPU airbag to complete the inflation and deflation adjustment, so that the head pillow and body pillow can automatically adapt the support height according to the supine and side sleeping positions. It can adaptively fit the support needs of the head, neck, shoulders and waist under different sleeping positions, effectively maintain the neutral position of the spine, and improve sleep quality and spinal health.

[0018] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0019] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1

[0020] This embodiment provides an intelligent adjustable head, neck, and body integrated pillow, such as... Figure 1 As shown, the device includes a body bolster 1 and a headrest 2. The headrest 2 has a downward-curving fossa area 21 in the middle of its front-to-back direction. This fossa area 21 accommodates the back of the head when sleeping on one's back, providing a snug fit that conforms to the head's curve. An upward-curving side-sleeping support area 22 is located in front of the fossa area 21. This area supports the side of the head when the user sleeps on their side, compensating for the height difference between the head and the bed surface caused by shoulder width. A shoulder and neck support area 23 is located in front of the side-sleeping support area 22. This shoulder and neck support area 23 has a trapezoidal structure, with its height gradually decreasing from one end connected to the side-sleeping support area 22 to the other end. It fills the gap between the cervical spine and the pillow surface when sleeping on one's back, maintaining the natural physiological curvature of the cervical spine.

[0021] The headrest 2 has two structural designs. One design uses the same seven-layer composite structure as the body pillow 1. The other design places the headrest 2 at the middle of one end of the body pillow 1. The headrest 2 includes a skin-friendly cover and a filling layer. The filling layer is a flexible, resilient material selected from one or more of polyurethane foam, memory foam, latex, thermoplastic polyurethane elastomer, gel, bio-based polyurethane, EVA, or silicone. The skin-friendly cover includes a detachable outer cover and an inner cover. The outer cover is placed outside the inner cover, and the inner cover is placed outside the filling layer. The skin-friendly cover adopts a double-layer detachable structure, consisting of an outer cover and an inner cover. Both the outer cover and the inner cover have hidden double zippers for easy disassembly and cleaning. The outer cover is washable and made of breathable, environmentally friendly, safe, and skin-friendly fabric. The inner cover uses a fabric with a higher thermal conductivity than the outer cover, providing better heat dissipation. The inner cover is placed directly outside the filling layer, and the outer cover covers the outer side of the inner cover.

[0022] like Figure 2 As shown, the body pillow 1 adopts a seven-layer composite structure, which consists of a skin-friendly fabric layer 3, a touch-sensitive layer 4, a sensor sensing layer 5, a body-sensing layer 6, an airbag execution layer 7, a support layer 8, and a bottom anti-slip layer 9, from top to bottom.

[0023] The skin-friendly fabric layer 3 includes an outer pillowcase and an inner pillowcase. The outer pillowcase is made of high-grammage spandex elastic fabric with four-way stretch properties, allowing it to stretch freely with the shape of the air bladder when it is raised, without generating additional tensile resistance. This ensures that the pressure signal collected by the sensor sensing layer 5 is not interfered with by the fabric tension, guaranteeing the accuracy of sleeping posture recognition. The inner pillowcase is made of bird's-eye mesh fabric, which is lightweight and breathable. Its fibers have grooved cross-sections, which create a capillary effect, quickly guiding and diffusing sweat from the head and neck area away from the skin surface, thus wicking away moisture and keeping the pillow surface dry and comfortable.

[0024] The airbag execution layer 7 is equipped with a TPU airbag 10. The TPU airbag 10 includes a head airbag unit, a neck airbag unit, and a waist airbag unit that can be independently inflated and deflated. The head airbag unit and the neck airbag unit are located in the occipital region 2. Specifically, the head airbag unit is located inside the fossa region 21 and the side sleeping support region 22, and the neck airbag unit is located inside the shoulder and neck support region 23.

[0025] In some exemplary embodiments, the TPU airbag 10 is a one-piece structure, internally divided into multiple independent and sealed chambers by thermoforming. Specifically, these include: a head chamber corresponding to the head airbag unit, a neck chamber corresponding to the neck airbag unit, and a left lumbar chamber, a middle lumbar chamber, and a right lumbar chamber corresponding to the lumbar airbag unit. The left lumbar chamber, the middle lumbar chamber, and the right lumbar chamber are independently sealed and their inflation and deflation can be controlled separately to achieve differentiated support for different lumbar regions.

[0026] In some other exemplary embodiments, the TPU airbag 10 has a split structure, including independent head airbags, neck airbags, and lumbar airbags, each connected to the pneumatic system via independent tubing. The head airbag is located inside the fossa area 21 and side-sleeping support area 22 of the occipital region 2, the neck airbag is located inside the shoulder and neck support area 23, and the lumbar airbag is located below the lumbar region of the body occipital region 1. Each airbag is independently controlled for inflation and deflation, and can be independently adjusted in height according to the user's sleeping posture and body shape, thus achieving a coordinated head, neck, and waist alignment function.

[0027] The tactile layer 4 is a 2cm thick 40D gel or beaded porous breathable memory foam. As the first buffer between the body and the pillow, it provides a soft, enveloping feel. The sensor layer 5 contains an array of pressure sensors, a piezoelectric sensor strip, and air pressure sensors. The array of pressure sensors collects the contact area and instantaneous pressure peaks of the user's head, face, and waist, generating a pressure distribution map. The control system uses this map to identify the user's current sleeping position (back, left, or right). The piezoelectric sensor strip captures weak vibration signals, including breathing fluctuations, heart rate fluctuations, and acceleration impacts during turning over, providing data support for determining the user's sleep depth. Multiple air pressure sensors are installed, each connected to the head, neck, and waist airbag units via independent air passages. These sensors monitor the air pressure inside each airbag unit in real time, feeding the pressure signals back to the control system for independent closed-loop control of each airbag unit. This prevents over-inflation leading to excessive pressure or under-inflation leading to support failure.

[0028] The somatosensory layer 6 is made of high-polymer cold foam. As a transition layer between the sensor sensing layer 5 and the airbag execution layer 7, it utilizes its uniform density distribution and excellent cushioning performance to absorb the localized pressure generated during airbag inflation, ensuring a more even distribution of support force on the human body contact surface when the airbag is inflated, preventing the user from feeling the hard support at the airbag edges. The support layer 8 is a 3cm thick high-elasticity support sponge, providing a stable load-bearing foundation for the entire upper structure. The bottom anti-slip layer 9 is a 3D mesh bottom fabric with silicone particles 11 on its bottom surface. Figure 3 As shown; or it may have Velcro 12, such as Figure 4 As shown; or it may have a zipper structure. This is used to securely connect to the mattress surface and prevent the pillow from shifting horizontally during use. Meanwhile, the anti-slip bottom layer 9, combined with Velcro or zipper structures, facilitates the removal, washing, and airing of the entire pillow.

[0029] In some other exemplary embodiments, the bottom surface of the anti-slip layer 9 is provided with silicone particles 11 and a zipper, or with Velcro 12 and a zipper, or with silicone particles 11 and Velcro 12, or with silicone particles 11, Velcro 12 and a zipper.

[0030] The airbag execution layer 7 also features an elastic bracing structure to prevent uncontrollable horizontal expansion of the TPU airbag 10 during inflation, ensuring stable alignment of the support point with the midline of the human spine and controlling horizontal displacement within ±2mm. The elastic bracing structure is internal to the airbag: it includes several elastic bracing bands positioned inside the TPU airbag 10. The two ends of each band are fixedly connected to the inner walls of the upper and lower sections of the TPU airbag 10 via thermoforming welding, forming vertical constraints. The elastic bracing bands are arranged in a matrix inside the airbag, with a spacing of 20-40mm between adjacent bands. During inflation, the elastic bracing bands limit the maximum separation distance between the upper and lower sections, forcing the airbag to expand primarily in the vertical direction. During deflation, the elastic bracing bands, relying on their own resilience, assist the upper and lower sections in moving closer together, accelerating the expulsion of gas from the airbag and causing it to quickly return to a flattened state.

[0031] In some other exemplary embodiments, the elastic tension bands are arranged in concentric circles inside the airbag.

[0032] In some other exemplary embodiments, the elastic brace structure is an externally mounted airbag: it is an elastic restraint net or elastic restraint band structure that wraps around the outer surface of the TPU airbag 10 to restrict the airbag from the outside.

[0033] like Figure 5 As shown, the present invention also includes a pneumatic system and a control system. The pneumatic system includes an air pump, an on / off control valve, an air pipeline, and a normally open pressure relief safety valve. The array pressure sensor, piezoelectric sensor strip, air pressure sensor, air pump, on / off control valve, and normally open pressure relief safety valve are all electrically connected to the control system.

[0034] The air pump uses a 24V dual-head isolation diaphragm pump to provide inflation power. The air pump is connected to a shock-absorbing support structure and is externally covered with closed-cell sound-absorbing cotton to absorb vibrations and noise generated during operation. The opening and closing control valve is a silent proportional valve, which, in conjunction with the pulse width modulation signal of the control system, achieves linear inflation and deflation control of each airbag unit, avoiding sudden height changes caused by step-like lifting. The air pump is connected to the TPU airbag 10 via air pipes, and each airbag unit's corresponding air pipe is equipped with an independent opening and closing control valve. The inlet of the normally open pressure relief safety valve is connected to the vent of the TPU airbag 10. During normal power-on operation, this safety valve remains closed to ensure normal inflation and pressure maintenance of the airbag; when the system is powered off or the control system issues a pressure relief command, the safety valve automatically opens, allowing the gas inside the airbag to be quickly discharged to the atmosphere, preventing over-inflation damage or safety hazards caused by the inability to depressurize due to power failure.

[0035] The control system includes a control circuit board and an MCU chip and a wireless communication unit mounted on the control circuit board. The MCU chip adopts the ARM Cortex-M4 architecture, and its computing power is sufficient to support the real-time operation of local AI algorithms, including the fusion processing of multimodal sensor signals, attitude recognition, dynamic alignment logic calculation, and the execution of closed-loop control algorithms. The wireless communication unit is electrically connected to the MCU chip and includes a Bluetooth module and / or a WiFi module for establishing bidirectional communication connections with mobile terminal devices such as smartphones and iPads.

[0036] This invention has two adjustment modes: adaptive adjustment mode and manual adjustment mode.

[0037] In adaptive adjustment mode: The MCU chip on the control circuit board uses pressure distribution data collected by the array pressure sensors in sensor perception layer 5 to determine whether the user is sleeping on their back, left side, or right side using a sleeping posture recognition algorithm, completing the "sensing" and "judgment" stages. It then calculates the target support height using a preset support model, completing the "decision" stage. The MCU chip controls the pneumatic system to inflate and deflate each airbag unit of the TPU airbag 10 according to the target height, completing the "execution" stage. Once the target state is reached, the opening and closing control valve closes to stop the adjustment. When sleeping on their back, the head airbag unit height is automatically lowered and the lumbar airbag unit height is raised; when sleeping on their side, the head airbag unit height is automatically raised and the lumbar airbag unit height is automatically lowered.

[0038] In manual adjustment mode: The user inputs the target support parameters through a mobile terminal application. The wireless communication unit receives the parameters and transmits them to the MCU chip. The MCU chip adjusts each airbag unit of the TPU airbag 10 according to the parameters. The MCU chip integrates a parameter memory module to record the height parameters set by the user and automatically recall them in subsequent use. The user can independently adjust the target support height of the head airbag unit and the lumbar airbag unit in supine and side-lying positions. The MCU chip stores the user's personalized height parameters in its memory, defining it as a dedicated mode. In subsequent use, the MCU chip can automatically recall this dedicated mode and allow the user to make minor adjustments through the mobile terminal application. When the user makes manual fine adjustments, the MCU chip captures the adjustment behavior and records it as a "feedback" signal. This signal serves as a key label input to the system for optimizing the user-specific model.

[0039] Upon first use, the user inputs basic information via a mobile application, including nickname, gender, age, height, weight, BMI, and preferred sleeping position. The MCU chip builds an individual user model based on this information and generates initial support parameters. The mobile application guides the user to learn the correct sleeping position, after which the user lies flat in the designated position on the device. The MCU chip automatically learns the user's sleeping position and controls the pneumatic system to adjust the TPU airbag 10 to the system's recommended height. The user can further manually fine-tune the position using the mobile application to achieve personalized support. Through this complete cycle of "perception-judgment-decision-execution-feedback," the MCU chip repeatedly corrects the user's body shape and support weight factors, achieving an "evolutionary" process.

[0040] During use, the MCU chip collects the following data: sleeping posture distribution data, support height adjustment data, number of turns and pillow movement data. The MCU chip integrates a sleep data analysis module, which statistically analyzes sleep duration, sleep onset time, deep sleep / light sleep ratio, number of turns, number of nighttime awakenings, and pillow movement based on the above data. It generates a sleep quality assessment result, which is transmitted to a mobile terminal application for display via a wireless communication unit. With increased use, the MCU chip continuously learns the user's sleep habits and support preferences, automatically adjusting the weight parameters in its customized model to gradually achieve a dynamic evolution that results in a more comfortable and healthier fit.

[0041] The mobile terminal device has a corresponding control APP or WeChat mini program installed, which has the following functions: Firstly, the device control function: displays the device's current battery level, network connection status, and binding status in real time; provides adjustment controls for supine and side-lying heights; and displays the dynamic effects of the adjustment status.

[0042] Secondly, the sleep report function: The MCU chip works with the WeChat mini-program to automatically generate daily, weekly, and monthly sleep reports, presented in chart format. Report content includes: comprehensive sleep score, total sleep duration and comparison with historical data, deep sleep, light sleep, wakefulness, time spent away from the pillow distribution, percentage of time spent sleeping on the back and side, number of times the user turns over, number of times the user wakes up at night, and records of time spent away from the pillow. Users can view and share sleep reports within the WeChat mini-program. The sleep report includes system prompts on the current status of the user's personalized model, as well as a visual display of the "getting closer to the body as you sleep" progress.

[0043] Thirdly, the personal center function: manage user profiles, view device information, and support remote diagnostics and firmware upgrades.

[0044] Fourthly, auxiliary functions: providing online customer service, guidance on learning correct sleeping posture, personalized height suggestions, after-sales service, and access to purchase products.

[0080] In summary, the intelligent adjustable head, neck, and body integrated pillow provided in this embodiment, through the coordinated setup of a seven-layer composite body pillow 1, independently inflatable and deflated TPU airbags 10, a sensor sensing layer 5 including an array pressure sensor, a piezoelectric sensor strip, and a pneumatic sensor, and a pneumatic and control systems, can accurately identify supine, left-side, and right-side sleeping postures based on the multimodal pressure distribution signals collected by the array pressure sensor and the piezoelectric sensor strip. The control system drives the pneumatic system to adjust the inflation and deflation of the head airbag unit, neck airbag unit, and lumbar airbag unit of the TPU airbag 10. This achieves dynamic alignment logic: lowering the head height, raising the lumbar height, and adjusting the neck height when sleeping supine; and raising the head height, lowering the lumbar height, and adjusting the neck height when sleeping on the side. This allows the head pillow 2 and body pillow 1 to adaptively match the support height according to the sleeping posture, helping to maintain the head, neck, and waist in a neutral spinal position and effectively dispersing pressure on the neck and waist. Meanwhile, closed-loop control is achieved through a barometric pressure sensor, adaptive optimization of the exclusive model is achieved through a parameter memory module and preference learning, and sleep data monitoring, sleep report generation, device control and user interaction functions are realized through a wireless communication unit and an APP or WeChat mini program on a mobile terminal device. This forms a complete data closed loop of "perception-judgment-decision-execution-feedback-evolution", gradually realizing the dynamic evolution of "the more you sleep, the better it fits, the healthier you become", providing users with an intelligent, personalized and comfortable sleep experience and spinal health protection. Example 2

[0081] This embodiment provides an adaptive adjustment method for an integrated head, neck, and body pillow, used in the intelligent adjustable integrated head, neck, and body pillow provided in Embodiment 1, such as... Figure 6 and Figure 7 As shown, the specific steps of this method are as follows: S000, Initial Learning: S010. In response to the user's first use or learning instruction, the control system sends a prompt message to the user's mobile terminal device via the wireless communication unit, guiding the user to maintain preset sleeping positions in sequence: supine, left side, and right side, and hold these positions for a preset time. The preset time is 5 to 30 seconds, allowing the user's head, neck, and waist to naturally conform to the head socket area 21, side-sleeping support area 22, shoulder and neck support area 23, and waist area of ​​the body bolster 1.

[0082] S020. The control system uses the array pressure sensors in the sensor perception layer 5 to collect the pressure distribution signals of the user in each preset sleeping position, extracts the corresponding pressure feature vector and distribution pattern, and generates a personalized back sleeping pressure distribution template, left-side sleeping pressure distribution template and right-side sleeping pressure distribution template that match the user. At the same time, it collects and generates preset air pressure values ​​for back sleeping, left-side sleeping and right-side sleeping corresponding to the appropriate height, and stores the above templates and preset air pressure values ​​in the memory as the basis for subsequent sleeping position recognition and air pressure adjustment.

[0083] If the user skips the initialization learning step, the preset universal supine pressure distribution template, left-side sleeping pressure distribution template, and right-side sleeping pressure distribution template in the memory will be used for comparison.

[0084] S100: Multimodal pressure distribution signals of the human head, neck and waist are collected by a sensor sensing layer 5 installed in the occipital region 1.

[0085] Specifically, the array pressure sensor collects the contact area and instantaneous pressure peak of the user's head, face, and waist to generate a pressure distribution map; the piezoelectric sensor captures breathing fluctuations, heart rate fluctuations, and acceleration impact signals during turning over; and each air pressure sensor monitors the air pressure value inside the corresponding airbag unit in real time. All of the above multimodal signals are transmitted to the control system.

[0086] S200: The control system identifies the user's current sleeping position based on the pressure distribution signal. The sleeping positions include sleeping on your back, sleeping on your left side, and sleeping on your right side.

[0087] Specifically, it includes: S210 The control system acquires real-time pressure values ​​from multiple collection points in the sensor perception layer 5, including the fossa region 21, the side-sleeping support region 22, the shoulder and neck support region 23, and the left, middle, and right lumbar regions, and constructs a real-time pressure feature vector.

[0088] S220. The real-time pressure feature vector is compared and matched with the user-personalized supine pressure distribution template, left-side sleeping pressure distribution template and right-side sleeping pressure distribution template generated and stored in the memory after initial learning in step S000. In the case where initial learning is not performed, the general default supine pressure distribution template, left-side sleeping pressure distribution template and right-side sleeping pressure distribution template built into the memory can be directly called for comparison.

[0089] The comparison logic includes calculating the similarity distance D between the real-time pressure feature vector and the pre-stored template vector. When the similarity distance D is less than a preset threshold, it is determined to be a successful match.

[0090] S230. Based on the comparison and matching results, determine whether the user is currently sleeping on their back, left side, or right side.

[0091] S300: The control system inflates or deflates the head airbag unit, neck airbag unit, and waist airbag unit of the TPU airbag 10 according to the current sleeping posture, and adjusts the height of the corresponding sections of the headrest 2 and bodyrest 1 to achieve neutral spinal alignment.

[0092] The adjustment logic specifically includes: When the user is identified as sleeping on their back, the system controls the inflation of the lumbar airbag unit to increase the lumbar support height, controls the deflation of the head airbag unit to lower the head pillow height, and controls the adjustment of the neck airbag unit to a preset height that matches the user's back sleeping position, in order to fill the gap in the cervical curve and maintain the natural physiological curvature of the cervical spine.

[0093] When the user is identified as sleeping on their side, the lumbar airbag unit is deflated to lower the lumbar support height, the head airbag unit is inflated to raise the head pillow height, and the neck airbag unit is adjusted to a preset height that matches the side sleeping position to provide stable neck support.

[0094] During the adjustment process, the control system monitors the air pressure inside each airbag unit in real time through air pressure sensors installed in the sensor sensing layer 5, and feeds the air pressure signal back to the control system. The control system compares the measured air pressure value with the target air pressure value, and adjusts the opening degree of the opening and closing control valve and the working state of the air pump through a closed-loop algorithm until the actual air pressure value reaches the target range. After the adjustment is completed, the control system controls the corresponding opening and closing control valve to close, so that the TPU airbag 10 is maintained at the target air pressure state.

[0095] This method also includes manual adjustment control: In response to the height adjustment command input by the user through a mobile terminal device, the control system inflates or deflates each airbag unit of the TPU airbag 10 to adjust it to the height specified by the user; the height specified by the user is stored in the memory as the preset height corresponding to the sleeping position; the user-specified height stored in the memory is retrieved, and the air pump is controlled to adjust the airbag unit to that height.

[0096] When a user performs manual adjustments, the system marks the current real-time pressure feature vector as a calibration feature and updates the preset height parameter for the corresponding sleeping position based on the manually adjusted height value. A manual intervention weighting factor α (0.5 < α < 1) is introduced. In the next identification and comparison, if the similarity between the real-time signal and the calibration feature reaches a preset threshold, the manually adjusted height parameter is used as the adjustment target.

[0097] A user preference feature library is established in the memory to record the frequency and value of manual adjustments made by users for different sleeping positions. When the system detects that the height value of manual adjustments made by the user for the same sleeping position N times consecutively (N is 3 to 10 times) tends to be consistent, the system automatically overwrites the preset height generated during initialization with the consistent height value, thereby achieving closed-loop optimization of the sleeping position recognition and height adjustment algorithm.

[0098] This method also includes preference learning and adaptive model optimization: When a user manually fine-tunes the height of the headrest 2 or bodyrest 1 via a mobile terminal device, the control system records the user's adjustment behavior, adjustment range, and corresponding postural environment. When the system detects that the same user is continuously making the same adjustment during multiple sleep cycles, it automatically determines that the user's physiological curvature has specific support needs, updates the user's corresponding body type-support weight factor, and adds the corresponding height compensation amount during subsequent automatic adjustments.

[0099] Through multiple perception-feedback cycles, the system gradually learns a personalized sleep model for each user.

[0100] This method also includes steps for sleep data monitoring and report generation: During the user's sleep, the control system collects pressure distribution signals through the array pressure sensors in the sensor sensing layer 5, and collects micro-motion signals through the piezoelectric sensor strip in the sensor sensing layer 5. The micro-motion signals include breathing fluctuations, heart rate fluctuations, and acceleration impacts when turning over.

[0101] The control system records the user's supine sleeping time, side sleeping time, number of times the user leaves the pillow, number of times the user turns over, heart rate, breathing, and total sleep duration based on the collected signals, and generates a sleep report based on the recorded data.

[0102] Sleep reports include daily, weekly, and monthly reports, and include sleep scores, sleep analysis data, and report interpretation.

[0103] The control system sends sleep reports to the user's mobile terminal device via a wireless communication unit, allowing the user to view them in the corresponding control APP or WeChat mini-program.

[0104] In summary, this invention relies on an array of pressure sensors and piezoelectric sensor strips inside the pillow to collect multimodal pressure distribution signals of the human head, neck, and waist and identify the corresponding sleeping posture. Based on the identification results, it controls each unit of the internal TPU airbag to complete the inflation and deflation adjustment, so that the head and body pillow can automatically adapt the support height according to the supine and side sleeping positions. It can adaptively fit the support needs of the head, neck, shoulders, and waist under different sleeping positions, effectively maintain the neutral position of the spine, and improve sleep quality and spinal health.

[0105] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
