Description

Technical Field

[0001] This invention relates to the field of smart pillow technology, specifically to a method for adaptive height adjustment of an AI-powered head and neck sleeping posture pillow. Background Technology

[0002] Sleep health is an important component of human health. As a core sleep aid, the pillow's height, support, and compatibility with the body's sleeping posture directly affect the physiological curvature of the cervical spine, thus determining sleep quality and cervical spine health. Traditional pillows are mostly of fixed height and made with single filling materials such as cotton, down, or memory foam, providing only a fixed support effect and failing to adapt to the different height needs of the two core sleeping postures: back sleeping and side sleeping.

[0003] When sleeping on your back, the natural curvature of the back of your head and neck requires a lower pillow support height. When sleeping on your side, the support of the shoulders and the fit between the face and neck require a higher pillow support height. A pillow with a fixed height can easily cause the neck to be unsupported when sleeping on your back and the head to tilt when sleeping on your side. Long-term use can easily lead to problems such as cervical strain, frequent turning over in sleep, and a high percentage of light 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 adjust height and pressure sensors to detect changes in sleeping posture. However, they generally lack AI-based sleeping posture recognition logic based on head and neck pressure distribution. They cannot accurately distinguish between supine and side sleeping positions or achieve real-time adaptive height adjustment for each sleeping zone. Furthermore, they lack personalized learning, height memory, and closed-loop analysis and feedback mechanisms for sleep data. Their control logic is simplistic, and their adjustment accuracy and user experience are poor, failing to meet users' needs for a precise, comfortable, and intelligent sleep experience. Summary of the Invention

[0005] The purpose of this invention is to provide an AI pillow with adaptive height adjustment method for head and neck sleeping posture, which aims to improve the problem that existing smart pillows are unable to accurately identify sleeping posture and cannot automatically adjust the support height of different zones according to sleeping posture.

[0006] This invention is implemented as follows: a method for adaptive height adjustment of an AI-powered pillow for head and neck sleeping posture, such as... Figure 7 As shown, it includes the following steps: S100: Collects pressure distribution signals of the human head and neck through an array of sensor strips set inside the pillow; S200. Identify the user's current sleeping position based on the pressure distribution signal, wherein the sleeping position includes sleeping on the back and sleeping on the side; S300: Based on the identified current sleeping posture, inflate or deflate the matrix airbags inside the pillow, and adjust the height of the corresponding section of the pillow to a preset height that matches the sleeping posture.

[0007] Furthermore, the steps for identifying the user's current sleeping position based on the pressure distribution signal specifically include: S210. Acquire the pressure values ​​of multiple collection points in the array sensing strip that correspond to the back of the human head and face, or the back of the human head and ears, or the back of the human head, face and neck. S220. Compare the pressure value with the pre-stored supine pressure distribution template and side-sleeping pressure distribution template in the memory; S230. Determine the current sleeping position based on the comparison results.

[0008] 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.

[0009] 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.

[0010] 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 position and stay for the preset time; S020. Collect the pressure distribution signal under the preset sleeping position, generate a sleeping position pressure distribution template corresponding to the user, and store it in the memory.

[0011] Furthermore, it also includes manual adjustment control: In response to the user's height adjustment command input via mobile terminal or adjustment button, the matrix airbag is 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 matrix airbags to that height.

[0012] Furthermore, the matrix airbags inside the pillow are inflated or deflated, and the height of the corresponding sections of the pillow is adjusted to a preset height that matches the sleeping position. Then, the air valve is closed, and the heat dissipation element inside the pillow is activated to dissipate heat from the heating element inside the pillow.

[0013] Furthermore, it also includes: The system continuously collects pressure distribution signals during the user's sleep, records the user's supine sleeping time, side sleeping time, number of times the user is out of pillow, number of times the user turns over, and total sleep duration, and generates a sleep report based on the recorded data. The sleep reports include daily, weekly, and monthly reports, and include sleep scores, sleep analysis data, and report interpretations.

[0014] Furthermore, the sleep score is calculated based on the total sleep duration, deep sleep duration, and light sleep duration, and may optionally be corrected based on the number of times the person turns over and / or the number of times they wake up.

[0015] Furthermore, it also includes: The sleep report is sent to the user's mobile device via the pillow's wireless communication unit, allowing the user to view it in a mini-program or app.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention relies on the array sensing strip built into the pillow to collect the pressure distribution signal of the human head and neck and identify the corresponding sleeping posture. Then, based on the identification result, it controls the internal matrix airbags to complete the inflation and deflation adjustment, so that each support zone of the pillow can automatically adapt to the appropriate support height according to the supine and side sleeping positions. Its control logic is simple and reliable, and can adaptively fit the support needs of the head, neck and shoulder parts under different sleeping positions, effectively improving sleep comfort.

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.

[0020] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1

[0021] like Figure 1 As shown, this embodiment provides an AI pillow for head and neck posture, including a home textile pillow module. The home textile pillow module is ergonomically divided into sections. A downward-curving concave head area 3 is provided in the middle part along the front-back direction to fit and accommodate the back of the head when sleeping on one's back, so that the pillow as a whole forms a natural curve that conforms to the human head and neck. On the front and back sides of the head area 3, there are upward-curving neck support areas A 4 and B 5 respectively. The height of neck support area A 4 is lower than that of neck support area B 5, and the height difference between neck support area A 4 and neck support area B 5 is 1cm to 10cm, thus forming a high and low double sleeping area. Users can choose to use the high side or the low side according to their own preferences.

[0022] like Figure 2 and Figure 4As shown, the home textile pillow module includes a cover 1 and a filling layer 2. The filling layer 2 is a flexible rebound material layer, selected from one or more of polyurethane foam, memory foam, latex, thermoplastic polyurethane elastomer, gel, bio-based polyurethane, EVA, or silicone. The cover 1 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 2. The cover 1 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 2, with the outer cover covering the outside of the inner cover. Mesh fabric or ventilation holes are provided at corresponding positions on the bottom of the cover 1 to achieve convection heat dissipation.

[0023] like Figure 2 , Figure 4 and Figure 6 As shown, the AI ​​head and neck sleeping posture pillow, in addition to the home textile pillow module, also includes at least one functional inner core 9, a hardware module, a charging and discharging module, and a matrix airbag assembly. The functional inner core 9 is located within the filling layer 2 and is a rigid or semi-rigid shell, situated within a pre-set contoured groove inside the filling layer 2. The functional inner core 9 has an air pipe interface for connecting to the matrix airbags and ventilation holes or a heat-conducting surface for heat dissipation. A positioning and fixing structure 6 is provided between the functional inner core 9 and the contoured groove to limit the relative displacement of the functional inner core 9 within the filling layer 2. The positioning and fixing structure 6 includes a buffer positioning layer surrounding the functional inner core 9, selected from one or more of sponge, foam, silicone, EVA, foamed materials, or air cushions. The control module is located within the functional inner core 9 and includes a PCB board, a main control chip, and a memory mounted on the PCB board. The main control chip is used for data processing, logic judgment, and instruction output, while the memory stores the sleeping posture recognition algorithm, pressure threshold, user height parameters, and sleep data, constituting the intelligent control core of the pillow. The control module also includes a program download component, which comprises a serial-port Wi-Fi programmer. Hardware modules electrically connected to the control module include a sensor unit, a wireless communication unit, an air pump, a battery, a charging / discharging interface, a power management unit, relays, and physical input components. The wireless communication unit, mounted on the PCB board, includes a Bluetooth module and / or a Wi-Fi module for establishing bidirectional communication with mobile terminal devices, supporting control and data transmission via a mini-program or app.

[0024] The control module is fixedly installed in the functional inner chamber 9, including a PCB board and a main control chip, memory, program download component, relays, input interfaces, and output interfaces mounted on the PCB board. The program download component includes a serial WIFI programmer. The main control chip is used for data processing, logic judgment, and instruction output. The memory is used to store sleeping posture recognition algorithms, pressure thresholds, user height parameters, and sleep data, forming the intelligent control core of the pillow. The relays are electrically connected to the control module, and the control module controls the power supply to and from the air pump through the relays.

[0025] An air pump, housed within the functional liner 9, is a silent pump that provides power and regulates air pressure for the matrix airbag assembly. A noise-reducing material layer, selected from one or more of sound-absorbing cotton, sound-absorbing sponge, or silicone sleeves, surrounds the air pump, reducing noise during operation and preventing sleep disturbance. A relay is electrically connected to the control module, which controls the air pump's on / off state via the relay. The hardware module also includes heat dissipation components such as heat sinks, as well as a passive cooling structure. This passive cooling structure includes a thermally conductive medium layer placed between the heat-generating electrical components and the heat dissipation components, with the heat dissipation components thermally connected to the shell of the functional liner 9. The thermally conductive medium layer is selected from one or more of thermally conductive silicone grease, thermally conductive pads, thermally conductive gel, thermally conductive tape, or phase-change thermally conductive materials. The shell of the functional liner 9 features heat dissipation fins or textured surfaces to increase the surface area in areas corresponding to the heat dissipation components. Of course, active cooling components such as cooling fans can also be installed if necessary. By setting the functional inner liner 9, the deformation of the soft filling layer 2 caused by the dispersed components can be avoided, the complexity of the internal wiring can be reduced, the irreversible indentation deformation of the filling layer 2 caused by the hard components under long-term use and turning pressure can be reduced, the poor contact phenomenon caused by the pulling of the wire harness in the soft material can be reduced, and the stability of the product structure, assembly efficiency and long-term reliability can be improved.

[0026] like Figures 2-5As shown, the sensor unit includes an array of sensing strips and a pressure sensor. The array of sensing strips is a flexible pressure sensor, selected from one or more of resistive, capacitive, or piezoelectric pressure sensors. The array of sensing strips is fixed to the filling layer 2 and the wrapping sleeve 1 and / or the wrapping sleeve 1 by stitching, gluing, heat pressing, or Velcro. The array of sensing strips can be a single continuous sensor or multiple independent sensors, with each independent sensor located in a different area, and each area corresponding to one or more sensors. When there are multiple array of sensing strips, they are arranged in a matrix, strip, or radial pattern; the spacing between adjacent array of sensing strips is 5mm to 50mm. The array sensing strip uses a fabric pressure sensor. The array sensing strip is set between the filling layer 2 and the wrapping sleeve 1, and is located at a position corresponding to the back of the head and ears, or the back of the head and face, or the back of the head, face and neck. The array sensing strip is set in at least one of the following areas: A. Neck support area 4, fossa area 3, B. Neck support area 5, and the side sleeping area corresponding to the face. The side sleeping area corresponding to the face spans A. Neck support area 4 and fossa area 3 or B. Neck support area 5 and fossa area 3. It is used to collect pressure distribution signals under different sleeping positions and transmit them to the control module.

[0027] When the flexible pressure sensor is a capacitive pressure sensor, it includes a first electrode layer, a dielectric layer, and a second electrode layer arranged sequentially from top to bottom. The dielectric layer is a flexible dielectric material layer, and its surface is provided with a microstructure array. The array sensing strip can use different types of sensor combinations, selected from combinations of capacitive and resistive sensors, capacitive and piezoelectric sensors, or resistive and piezoelectric sensors. Different types of sensors are arranged alternately or layered.

[0028] When the array sensing strip is a fabric pressure sensor, the fabric pressure sensor includes an array sensing strip, and the array sensing strip is set in the neck support area 4 or the fossa area 3 or the neck support area 5 or the side sleeping area corresponding to the human face. The side sleeping area corresponding to the human face is either across the neck support area 4 and the fossa area 3 or across the neck support area 5 and the fossa area 3.

[0029] When the array sensing strip consists of multiple fabric pressure sensors, such as Figure 2 and Figure 3As shown, the first type of array sensing band includes a first array sensing band 71, a second array sensing band 72, and a third array sensing band 73. The first array sensing band 71 is located in the neck support area 4 (A) corresponding to the human face. The third array sensing band 73 is located in the neck support area 5 (B) corresponding to the human face. The second array sensing band 72 is located in the fossa area 3 (B) corresponding to the back of the head. It is used to collect pressure distribution signals under different sleeping positions.

[0030] like Figure 4 and Figure 5 As shown, the second array sensing band includes a first array sensing band 74, a second array sensing band 75, a third array sensing band 76, a fourth array sensing band 77, and a fifth array sensing band 78. The first array sensing band 74 is positioned in the neck support area 4 (A) corresponding to the human neck; the second array sensing band 75 is positioned in the neck support area 4 (A) corresponding to the human face; the third array sensing band 76 is positioned in the fossa area 3 (B) corresponding to the human back of the head; the fourth array sensing band 77 is positioned in the neck support area 5 (B) corresponding to the human face; and the fifth array sensing band 78 is positioned in the neck support area 5 (B) corresponding to the human neck, thus more comprehensively collecting sleeping posture pressure signals.

[0031] like Figure 2 or Figure 4 As shown, the matrix airbag assembly is disposed in the filling layer 2, including one to five matrix airbags, air tubes, and an air distribution unit. An air pump can be selectively connected to any one or more matrix airbags through the air distribution unit and air tubes. The air distribution unit is electrically connected to the control module. The matrix airbag is a three-layer structure, including a primary airbag, a secondary airbag, and a tertiary airbag stacked sequentially from top to bottom and independent of each other. When there is only one matrix airbag, it extends horizontally through the A neck support area 4, the pit of the head area 3, and the B neck support area 5, and the overall shape of the matrix airbag is adapted to the shape of the home textile pillow module.

[0032] When the matrix airbags are set to 3, a preferred scheme is as follows: Figure 2As shown, the matrix airbag system includes airbag 81, airbag 82, and airbag 83. Airbag 81 is positioned in the neck support area A (4), airbag 82 in the fossa area (3), and airbag 83 in the neck support area B (5). The air tubes are correspondingly designated as air tube 1, air tube 2, and air tube 3, and the air distribution units are correspondingly designated as air valve 1, air valve 2, and air valve 3. Airbag 81 is connected to the air pump via air tube 1, and air valve 1 is installed on air tube 1. Airbag 82 is connected to the air pump via air tube 2, and air valve 2 is installed on air tube 2. Airbag 83 is connected to the air pump via air tube 3, and air valve 3 is installed on air tube 3. Air valves 1, 2, and 3 are all electrically connected to the control module. A pressure sensor is installed on the matrix airbag or the air tube connected to the matrix airbag and is electrically connected to the control module. It is used to collect the internal pressure signal of the matrix airbag and transmit it to the control module, detecting the internal pressure value of the airbag in real time and feeding it back to the control module to ensure accurate and stable altitude adjustment. Each matrix airbag is equipped with an independent pressure sensor, and the control module is configured to independently adjust the pressure of the corresponding matrix airbag based on the feedback value of each pressure sensor.

[0033] When the matrix airbags are set to 5, a preferred scheme is as follows: Figure 4 As shown, the matrix airbag system includes a first airbag 84, a second airbag 85, a third airbag 86, a fourth airbag 87, and a fifth airbag 88. The first airbag 84 is positioned within the A neck support area 4. The second airbag 85 is positioned in the transition zone between the A neck support area 4 and the fossa area 3, spanning both areas. The third airbag 86 is positioned within the fossa area 3. The fourth airbag 87 is positioned in the transition zone between the B neck support area 5 and the fossa area 3, spanning both areas. The fifth airbag 88 is positioned within the B neck support area 5. The trachea are correspondingly configured as a first trachea, a second trachea, a third trachea, a fourth trachea, and a fifth trachea. The airway distribution unit is correspondingly configured as a first air valve, a second air valve, a third air valve, a fourth air valve, and a fifth air valve. The first airbag 84 is connected to the air pump via a first air tube, and a first air valve is installed on the first air tube. The second airbag 85 is connected to the air pump via a second air tube, and a second air valve is installed on the second air tube. The third airbag 86 is connected to the air pump via a third air tube, and a third air valve is installed on the third air tube. The fourth airbag 87 is connected to the air pump via a fourth air tube, and a fourth air valve is installed on the fourth air tube. The fifth airbag 88 is connected to the air pump via a fifth air tube, and a fifth air valve is installed on the fifth air tube. The first, second, third, fourth, and fifth air valves are all electrically connected to the control module. Air pressure sensors are installed on the matrix airbags or the air tubes connected to the matrix airbags and are electrically connected to the control module. They are used to collect the internal air pressure signal of the matrix airbags and transmit it to the control module, thereby detecting the internal air pressure value of the airbags in real time and feeding it back to the control module to ensure accurate and stable altitude adjustment.

[0034] The air distribution unit is selected from at least one or a combination of low-power bistable holding solenoid valves and micro-motor driven rotary valves. The low-power bistable holding solenoid valve only requires pulse current drive during state switching; after switching, it maintains its state using permanent magnet force, requiring no continuous power supply. The control module can achieve parallel operations of inflating, deflating, or pressurizing multiple matrix airbags simultaneously by independently controlling the on / off state of each solenoid valve. When the flow channel switching element is a micro-motor driven rotary valve, the rotary valve includes a common air inlet and multiple selectable air outlets. The common air inlet is connected to the air pump, and the multiple selectable air outlets are connected to the corresponding matrix airbags via air pipes. The micro-motor is electrically connected to the control module, and by controlling the rotation angle of the micro-motor, it selectively connects the common air inlet to any of the selectable air outlets. When the flow channel switching element adopts a combination of rotary valve and solenoid valve, the rotary valve is used to selectively connect the air pump to a main air path, and the solenoid valve is located between the main air path and each matrix airbag for further air distribution. The number of solenoid valves is the same as the number of matrix airbags. The air inlet of each solenoid valve is connected to the air pump, and the air outlet of each solenoid valve is connected to a corresponding matrix airbag via an air pipe. The flow channel switching element is integrated at the air inlet of the matrix airbag or centrally located within a valve module, which is adjacent to the air pump. A noise-reducing material layer is surrounding the flow channel switching element; this material is selected from one or more of sound-absorbing cotton, sound-absorbing sponge, or silicone sleeves.

[0035] The hardware module also includes a power management unit, a battery, and a charging / discharging interface. The power management unit is electrically connected to the battery, control module, and charging / discharging interface to manage the battery's charging and discharging process. The charging / discharging interface is used to connect to an external power source to charge the battery and power various electrical components. The power management unit includes a charging management chip, a voltage conversion circuit, and a power monitoring circuit. The charging management chip controls the battery's charging current and voltage, achieving constant current and constant voltage charging. The voltage conversion circuit converts the battery's output voltage into the operating voltage required by the control module and hardware module. The power monitoring circuit monitors the battery's remaining power, voltage, current, and temperature in real time. The power management unit also includes a protection circuit, selected from one or more of overcharge protection, over-discharge protection, overcurrent protection, short-circuit protection, or over-temperature protection circuits. When an abnormal state is detected, the protection circuit automatically cuts off the charging or discharging circuit. The power management unit is configured to prioritize using the external power source to power the control module and hardware module while simultaneously charging the battery when connected to an external power source via the charging interface. When the battery is not installed or its charge is depleted, the control module and hardware module can still operate directly powered by the external power source.

[0036] The charging and discharging interface in the hardware module is selected from one or more of the following: Type-C interface, Micro-USB interface, Lightning interface, or DC power interface; when the charging interface is a Type-C interface, it supports the PD fast charging protocol or the QC fast charging protocol; the charging and discharging interface is located on the shell surface of the functional inner liner 9, the side of the wrapping sleeve 1, or led out to the outside of the pillow body through an extension line.

[0037] The battery is a rechargeable lithium battery, selected from lithium cobalt oxide batteries, lithium iron phosphate batteries, or ternary lithium batteries; the nominal voltage of the battery is 3.7V, and the capacity is 1000mAh to 5800mAh; the battery is fixedly installed inside the functional inner liner 9 by battery brackets or foam tape, and a buffer isolation layer is provided between the battery and the shell of the functional inner liner 9. The buffer isolation layer is selected from one or more of silicone pads, foam, or air cushions to absorb external impacts and vibrations.

[0038] The hardware module also includes a power indicator element, which is electrically connected to the control module or power management unit. The power indicator element displays the remaining battery power or charging status. The power indicator element is selected from one or more of monochrome or multicolor LED indicators, digital tubes, LCD displays, or electronic paper displays. The control module is configured to: when the battery power is above a first threshold, control the power indicator element to display blue or illuminate all LEDs; when the battery power is between the first and second thresholds, control the power indicator element to display blue or illuminate some LEDs; when the battery power is below the second threshold, control the power indicator element to display red or flash as a warning; and when the battery is charging, control the power indicator element to display blue or flash in a breathing light mode.

[0039] The control module is configured to issue a low battery warning signal and push it to the mobile terminal application via the wireless communication unit when the battery level is detected to be below a first low battery threshold. When the battery level is detected to be below a second low battery threshold, it automatically shuts down unnecessary functional modules, maintaining only basic standby functionality. The power management unit is configured to prioritize using external power to power the control module and hardware modules while simultaneously charging the battery when an external power source is connected via the charging interface. When the battery is not installed or is depleted, the control module and hardware modules can still operate directly powered by an external power source.

[0040] The hardware module also includes at least one physical input element, electrically connected to the control module, providing manual control independent of the mobile terminal application. The physical input element includes a power switch and adjustment buttons. The power switch manually controls the power supply to the entire pillow, while the adjustment buttons are stepless, allowing users to manually control the inflation or deflation of the matrix airbags to fine-tune the height. The control module is configured to save the adjusted height parameters to memory via a wireless communication unit after manual adjustment through the mobile terminal application, with the application interface displaying the current pillow height in real time. When the control module receives height adjustment commands from both automatic and manual adjustment modes simultaneously, it executes them according to a preset priority rule, with adjustments made through the mobile terminal application taking precedence over automatic adjustment.

[0041] The control module is configured to allow manual adjustment via a mobile terminal application, and then save the adjusted height parameters to the memory via a wireless communication unit. The application interface displays the current pillow height in real time. When height adjustment commands are received simultaneously from both automatic and manual adjustment modes, they are executed according to a preset priority rule, which prioritizes adjustments made via the mobile terminal application over those made via automatic adjustment mode.

[0042] This AI-powered head and neck posture pillow is equipped with an intelligent control system. It interacts with applications (mini-programs or apps) on mobile devices (such as smartphones) via a wireless communication unit, forming a complete intelligent height adjustment system. The system includes: a user interaction module, a sleeping posture recognition module, an adaptive adjustment module, a manual fine-tuning module, a parameter memory module, a sleep data analysis module, a personal health data management module, and a product shopping module.

[0043] The system interacts with users through a mobile terminal application, enabling intelligent adjustment, manual adjustment, parameter memory, and data analysis functions.

[0044] The AI-powered head and neck posture pillow offers two adjustment modes: adaptive and manual. Adaptive adjustment mode: The control module uses pressure distribution data collected by the array sensor strips and a sleeping posture recognition algorithm to determine whether the user is sleeping on their back or side. It then calculates the target support height based on a preset support model. The control module adjusts the airbag assembly by inflating and deflating according to the target height, stopping adjustment once the target is reached. When sleeping on their back, the corresponding area height automatically decreases; when sleeping on their side, the corresponding area height automatically increases. The air valve closes once the appropriate height is achieved. Manual adjustment mode: The user inputs target support parameters through the user interaction module of the mobile application. The control module adjusts the airbag assembly according to these parameters. A parameter memory module records the user's settings and automatically recalls them for subsequent use. Users can independently adjust the support height of the back and side sleeping areas. The system stores the user's personalized height parameters in memory, defining it as a "personalized mode." The system can automatically recall this mode for subsequent use, allowing the user to make minor adjustments based on it.

[0045] The AI-powered head and neck posture pillow features user modeling and initialization. Upon first use, the user inputs basic information via a mobile application, including nickname, gender, age, height, weight, BMI, and sleeping posture preferences. The system builds an individual user model based on this information and generates initial support parameters. The application guides the user to learn the correct sleeping posture. Subsequently, the user lies flat on the pillow in the designated position, and the AI-powered head and neck posture pillow automatically learns the user's sleeping posture and adjusts to the system's recommended height. The user can then manually fine-tune the position based on their own comfort to achieve personalized support.

[0046] During use, the system collects the following data: sleeping posture distribution data, support height adjustment data, number of times the user turns over, and data on whether the user is out of bed. Based on the above data, the sleep data analysis module performs statistical analysis on sleep duration, sleep onset time, ratio of deep sleep to light sleep, number of times the user turns over, number of times the user wakes up at night, and whether the user is out of bed, generating sleep quality assessment results, which are then displayed through the user interaction module.

[0047] The user interaction module (mobile application) has the following functions: Device control: Real-time display of the AI ​​pillow's current battery level, network connection status, and binding status; provides adjustment controls for back and side sleeping height; displays dynamic effects of the adjustment status. Sleep report function: The system automatically generates daily, weekly, and monthly sleep reports, presented in chart format. Report content includes: comprehensive sleep score (out of 100), total sleep duration and comparison with historical data, distribution of deep sleep / light sleep / awake / restless sleep time, percentage of back and side sleeping time, number of times turning over, number of nighttime awakenings, and restless sleep records. Users can view and share sleep reports within the application.

[0085] In summary, the AI ​​head and neck posture pillow provided by this invention, through the coordinated setup of a control module, a hardware module including a sensor unit and an air pump, and a matrix airbag assembly, can identify sleeping posture based on the pressure distribution signal collected by the array sensing strip, and automatically control the inflation and deflation of the matrix airbags to adjust the height of the corresponding sections of the pillow. This allows the pillow height to adaptively match the user's supine or side-sleeping position, providing stable and fitting support for the head and neck, and providing a reliable guarantee for improving the user's sleep quality.

[0086] Example 2 This embodiment provides a method for adaptive height adjustment of a head and neck sleeping posture AI pillow, used in the head and neck sleeping posture AI pillow provided in Embodiment 1, such as... Figure 7 and Figure 8 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 module sends a prompt message to the user's mobile terminal applet or APP through the wireless communication unit, guiding the user to maintain the preset sleeping positions of sleeping on their back, left side, and right side in sequence, and stay for a preset time, which is 5 to 30 seconds, so that the user's head and neck naturally fit with the pillow's pit area 3, neck support area A 4, and neck support area B 5.

[0087] S020. The control module collects pressure distribution signals of the user in each preset sleeping position through an array of sensing strips arranged between the cover 1 and the filling layer 2. It extracts the corresponding pressure feature vectors and distribution patterns, and generates personalized supine pressure distribution templates and side-sleeping pressure distribution templates that match the user. At the same time, it collects and generates preset air pressure values ​​for supine and side-sleeping corresponding to the appropriate height. The templates and preset air pressure values ​​are stored together in the memory as the basis for subsequent sleeping position recognition and air pressure adjustment.

[0088] If the user skips the initial learning step, the system compares the pre-set universal supine pressure distribution template with the side-sleeping pressure distribution template stored in memory. These pre-set templates are created by collecting large amounts of data on the pressure distribution of the head and neck in standard supine and side-sleeping positions in healthy adults, specifically in the pituitary region (3), neck support region (A), neck support region (B), and the corresponding facial area in side-sleeping positions. This data is then statistically fitted, feature extracted, and trained using algorithms before being pre-written into memory, making them suitable for general users who have not completed personalized learning.

[0089] S100: The pressure distribution signal of the human head and neck is collected in real time by an array of sensing strips installed inside the pillow. Specifically, the pressure of the back of the head, face or ears and neck area can be collected by the first array sensing strip 71, the second array sensing strip 72, the third array sensing strip 73, or the first array sensing strip 74, the second array sensing strip 75, the third array sensing strip 76, the fourth array sensing strip 77 and the fifth array sensing strip 78, and the collected pressure distribution signal is transmitted to the control module.

[0090] S200: The control module identifies the user's current sleeping position based on the received pressure distribution signal, including sleeping on the back and sleeping on the side.

[0091] Specifically, it includes: S210. The control module acquires the real-time pressure values ​​of multiple collection points in the array sensing strip that correspond to the back of the human head and face, or the back of the human head and ears, or the back of the human head, face and neck, and constructs a real-time pressure feature vector. S220. The real-time pressure feature vector is compared and matched with the user-personalized supine pressure distribution template and 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 and side-sleeping pressure distribution template built into the memory can be directly called for comparison.

[0092] 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.

[0093] S230. Based on the comparison and matching results, determine whether the user is currently in a supine or side-sleeping state.

[0094] S300: The control module retrieves the preset air pressure value corresponding to the current sleeping posture from the memory based on the identified current sleeping posture, and controls the air pump and corresponding air valve to inflate or deflate the matrix airbags inside the pillow, so that the air pressure inside the airbags reaches the preset air pressure that matches the current sleeping posture, so as to maintain the corresponding support height.

[0095] Specifically, the control module pre-stores preset air pressure values ​​for the airbags corresponding to supine and side-lying positions, and these preset air pressure values ​​correspond to the appropriate support height. When a supine sleeping position is detected, the control module controls the second airbag 82 to deflate, reducing the air pressure inside the second airbag 82 to the preset air pressure value corresponding to supine sleeping, thus creating a support height suitable for supine sleeping. When a side-lying position is detected, the control module controls the first airbag 81 or the third airbag 83 to inflate, increasing the air pressure inside the corresponding airbag to the preset air pressure value corresponding to side-lying, thus creating a support height suitable for side-lying. The air pressure sensor detects the airbag air pressure in real time and feeds it back to the control module, realizing closed-loop air pressure regulation, thereby stably maintaining the support height matched to the sleeping position. After the regulation is completed, the control module controls the corresponding air valve to close, keeping the matrix airbags at the target air pressure state and avoiding the energy consumption and noise generated by the continuous operation of the air pump.

[0096] This method also includes manual adjustment control: in response to the height adjustment command input by the user through a mobile terminal applet, APP or adjustment button on the pillow, the control module drives the air pump and corresponding air valve to work, inflating or deflating the matrix airbags to make the airbag pressure reach the target air pressure specified by the user; at the same time, the target air pressure specified by the user is updated to the preset air pressure value corresponding to the sleeping position and stored in the memory.

[0097] Manual adjustment control also includes adaptive optimization of the comparison logic: 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 is introduced, where 0.5 < α < 1. 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 preferentially used as the adjustment target.

[0098] The memory establishes a user preference feature library to record the frequency and value of manual adjustments made by users for different sleeping positions. When it is detected that the height value of manual adjustments made by the user for the same sleeping position for N consecutive times (N is 3-10-) tends to be consistent, the system automatically overwrites the preset height generated during initialization with the manual height, thereby achieving closed-loop optimization of the comparison algorithm.

[0099] The height value tends to be consistent, which means that when the difference between any two adjustment values ​​does not exceed the preset fluctuation threshold (the fluctuation threshold is 0.2cm to 0.5cm), the system automatically covers the preset height generated by the original initialization with the arithmetic mean of the N adjustment values, so as to realize the closed-loop optimization of the sleeping posture recognition and height adjustment algorithm.

[0100] The next time the user uses the pillow, the control module directly calls the preset air pressure value stored in the memory, controls the air pump and air valve to adjust the matrix airbag to the corresponding air pressure, so as to maintain the personalized support height and achieve a personalized experience of "one-time fine adjustment, long-term use".

[0101] After the matrix airbags are inflated or deflated to reach the preset airbag pressure value, the control module controls the corresponding air valve to close and activates the heat dissipation element set inside the filling layer 2 to dissipate heat from the main control chip and other heat-generating components, reduce the operating temperature of the components, and ensure the long-term stable operation of the electronic components inside the pillow.

[0102] This method also includes sleep data monitoring and report generation steps: During the user's sleep, the control module continuously collects pressure distribution signals through the array sensor strip, records data such as 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, and total sleep duration, and generates a sleep report based on the recorded data. Sleep reports include daily, weekly, and monthly reports, and the report content includes a sleep score, sleep analysis data, and report interpretation.

[0103] A 100-point scale is used to comprehensively assess users' sleep quality. The formula for calculating the sleep score is as follows: Sleep score = Deep sleep score + Sleep duration score + Sleep position stability score - Deduction for awakenings and nighttime awakenings Among them, the deep sleep score ranges from 0 to 40 points, the sleep duration score ranges from 0 to 30 points, the sleep posture stability score ranges from 0 to 20 points, and the deduction for waking up at night ranges from 0 to 10 points.

[0104] The scoring rules for each item are as follows: (1) The deep sleep score is determined based on the deep sleep percentage, which is the ratio of deep sleep duration to total sleep duration. When the deep sleep percentage is greater than or equal to 30%, it is scored as 40 points; for every 5% decrease in the deep sleep percentage, 7 points are deducted accordingly, with a minimum score of 0 points.

[0105] (2) The sleep duration score is determined based on the total sleep duration. When the total sleep duration is between 7 and 9 hours, it is scored as 30 points; when the total sleep duration is less than 6 hours or more than 10 hours, it is scored as 10 points; when the total sleep duration is between 6 and 7 hours or between 9 and 10 hours, it is scored according to a linear ratio.

[0106] (3) The score for stable sleeping posture is determined based on the number of times the body turns over. When the number of times the body turns over is less than or equal to 15, it is scored as 20 points; when the number of times the body turns over is between 16 and 25, it is scored as 15 points; when the number of times the body turns over is greater than 25, it is scored as 10 points.

[0107] (4) Deduction for waking up at night is determined based on the number of times you wake up at night. When you wake up 0 times, deduct 0 points; when you wake up 1 to 2 times, deduct 2 points; when you wake up 3 to 4 times, deduct 5 points; when you wake up 5 times or more, deduct 10 points.

[0108] In one specific scenario, when a user's deep sleep percentage is 25%, total sleep duration is 7.5 hours, number of turns is 12, and number of nighttime awakenings is 1, the deep sleep score is 33 points, the sleep duration score is 30 points, the stable sleeping posture score is 20 points, the nighttime awakening deduction is 2 points, and the final sleep score is 81 points.

[0109] In summary, this invention relies on the array sensor belt built into the pillow to collect pressure distribution signals of the human head and neck and identify the corresponding sleeping posture. Then, based on the identification results, it controls the internal matrix airbags to complete the inflation and deflation adjustment, so that each support zone of the pillow can automatically adapt to the appropriate support height according to the back sleeping and side sleeping positions. Its control logic is simple and reliable, and it can adaptively fit the support needs of the head, neck and shoulder parts under different sleeping positions, effectively improving sleep comfort.

[0110] This invention employs an initial learning process to collect pressure distribution signals under different sleeping positions upon first use, generating and storing personalized sleeping position templates. Subsequent uses are based on these templates for sleeping position recognition and height adjustment, ensuring precise matching of support height to the user's head and neck characteristics. Furthermore, this invention features a memory function; preset adjustment templates generated during learning and automatically stored after manual height adjustments by the user can be directly recalled for subsequent uses without repeated settings, achieving a personalized experience of "one-time fine-tuning, long-term applicability."

[0111] 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.
