Description

Technical Field

[0001] This invention relates to the field of pillow design and manufacturing technology, and in particular to a zoned adjustable health-customized pillow and its design method. Background Technology

[0002] In the pillow industry, existing traditional memory foam pillows and ordinary air-cushion pillows have significant shortcomings. Firstly, they lack personalized customization; most are standardized production models that cannot be tailored to individual user shoulder and neck dimensions and cervical curvature. This misalignment of support points with the body's physiological structure can easily lead to cervical fatigue with prolonged use. Secondly, their zoned support function is weak. Most are single-layer air-cushion pillows or only have a few zones, making it difficult to independently adjust for side sleeping, pillow height, or back head support. When changing positions (such as from back to side sleeping), the differentiated support needs of the shoulders and neck cannot be met, resulting in a sharp drop in support effectiveness. Thirdly, their structural stability is poor. Some multi-air-cushion pillows lack effective separation, allowing air to easily flow between air cells. Adjusting one air cell can affect other areas; furthermore, the air cells lack stability and are prone to shifting during use, disrupting the support layout. Fourthly, comfort and support are difficult to balance. Hard pillows are uncomfortable, while soft pillows offer insufficient support; traditional memory foam pillows have a fixed shape and cannot be adjusted, and ordinary air-cushion pillows lack cushioning, leading to a feeling of pressure with prolonged use. Summary of the Invention

[0003] Therefore, it is necessary to provide a zoned adjustable health-customized pillow and its design method to solve at least one of the above-mentioned technical problems.

[0004] To achieve the above objectives, a zoned adjustable health-customized pillow includes nine independent airbag units, a flexible partition, independent inflation / deflation channels, and memory foam composite fabric. The nine airbag units are connected by the flexible partition to form an independent structure with no gas flow. Each airbag unit is equipped with an independent inflation / deflation channel for connecting to an external inflation / deflation device. The airbag units can be nearly rectangular, trapezoidal, arc-shaped, or wave-shaped. The arc-shaped airbag units adapt to the curve of the human neck. The nine airbag units are distributed according to the head, neck, and shoulders, respectively corresponding to side sleeping support, high / low pillow support, and back head support. The memory foam composite fabric covers the outside of the airbag units and forms a curved pillow shape that conforms to the physiological curvature of the cervical spine.

[0005] This invention also provides a design method for a zone-adjustable health-customized pillow, used in the aforementioned zone-adjustable health-customized pillow, the method comprising the following steps: Step S1: Collect human shoulder and neck dimensions and cervical curvature using a body composition analyzer to generate personalized physiological data; Step S2: Determine the filling cavity volume and spatial layout of the nine zones of the airbag unit based on personalized physiological data. By processing flexible partitions and setting the position and size of the nine zones, nine independent chambers without gas crossflow are formed. Step S3: Adapt the airbag unit according to the functional requirements of side sleeping support, high and low pillow support and back head support of the independent chamber, and set an independent inflation and deflation channel for each airbag unit. Design a connection interface with the external inflation and deflation device at the end of the independent inflation and deflation channel. Step S4: Embed the nine independent airbag units into the corresponding independent chambers, fix the flexible partition to the edge of the airbag unit by suturing or bonding, and connect the independent inflation and deflation channels to the inflation port of the airbag unit to form an overall support structure. Step S5: Cut the memory foam composite fabric according to the outer contour of the overall support structure, cover the outside of the support structure, and use a hot-pressing molding process to shape the memory foam composite fabric to conform to the physiological curvature of the cervical spine, forming a curved pillow.

[0006] The beneficial effects of this invention are: 1. Based on personalized shoulder and neck dimensions and cervical curvature data collected by the body composition analyzer, the system precisely divides the space into nine zones and adapts them to the airbag units. Each airbag corresponds to different parts of the head, neck, and shoulders (side sleeping zone, high and low pillow zone, and back head support zone). At the same time, the independent inflation and deflation channels support manual / electric devices or mobile apps for adjustment. The height of each zone can be flexibly adjusted according to different sleeping positions such as supine and side sleeping. This not only adapts to the physiological differences of different people, but also achieves "one posture, one adjustment" scenario-based support.

[0007] Second, the airbag unit adopts differentiated structures such as arc (fitting the curve of the neck), trapezoid, and wave shape to closely fit the physiological contour of the head and neck; the outer memory foam composite fabric is heat-pressed to form a curved shape, which has both a soft touch and slow rebound characteristics; this design provides targeted support through airbags to maintain the physiological curvature of the cervical spine, and buffers pressure through memory foam to avoid the oppressive feeling of traditional pillows, greatly improving the comfort of use.

[0008] Third, the flexible partitions divide the nine airbag units into independent chambers without gas crossflow, forming a stable overall structure with stitching / adhesion processes to prevent airbag displacement; each airbag is equipped with an independent inflation / deflation channel, so adjusting a single airbag does not interfere with other areas, and the operation logic is clear; the interface design facilitates the connection of external devices, and users can adjust the air volume through simple operations such as buttons and knobs, balancing structural stability and ease of use.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0013] To achieve the above objectives, please refer to Figures 1 to 4 It includes nine independent airbag units, flexible partitions, independent inflation / deflation channels, and memory foam composite fabric. The nine airbag units are connected by flexible partitions to form an independent structure with no gas flow. Each airbag unit is equipped with an independent inflation / deflation channel for connecting to external inflation / deflation devices. The airbag units have a near-rectangular flat structure, trapezoidal structure, arc structure, or wave-shaped structure. Among them, the arc structure airbag unit adapts to the curve of the human neck. The nine airbag units are distributed according to the human head, neck, and shoulders, and correspond to side sleeping support, high and low pillow support, and back head support, respectively. The memory foam composite fabric covers the outside of the airbag units and forms a curved pillow shape that conforms to the physiological curvature of the cervical spine.

[0014] This invention also provides a design method for a zone-adjustable health-customized pillow, used in the aforementioned zone-adjustable health-customized pillow, the method comprising the following steps: Step S1: Collect human shoulder and neck dimensions and cervical curvature using a body composition analyzer to generate personalized physiological data; Of particular importance is that step S1 includes the following steps: Using the sole of the foot as the vertical reference plane, positioning reference frames are set up in front of and to the side of the human body. The longitudinal markings on the reference frames are aligned with the midline of the human spine, and the transverse markings are aligned with the horizontal height of the acromion. By using a contact measuring device that moves along the longitudinal gradation line, and fitting against the side of the shoulder and neck from the acromion point towards the spinous process of the cervical vertebrae, the distance between the endpoints of the measuring device's movement trajectory is recorded to obtain the lateral dimensions of the shoulder and neck. Simultaneously, through the non-contact detection component below the horizontal marking, detection signals are emitted at equal intervals along the longitudinal direction of the cervical spine from the spinous process of the seventh cervical vertebra to the spinous process of the second cervical vertebra. The coordinate feedback after the signal reflection is captured to form discrete sampling points of the cervical curvature. Using the spinous process of the seventh cervical vertebra and the acromion points on both sides as fixed anchor points, the lateral dimension data is bound to the coordinates of discrete sampling points to fit and form a three-dimensional physiological contour of the shoulder and neck, generating personalized physiological data.

[0015] In this embodiment, the foot-contacting surface is used as the vertical reference plane. An aluminum alloy positioning reference frame with a height of 2.2m and a width of 1.5m is set in front of and to the side of the human body. The frame surface is engraved with longitudinal and transverse markings with a spacing of 1mm. The longitudinal markings are aligned with the midline of the spine by a cross laser locator at the top. The transverse markings are adjusted to match the acromion level by a height sensor with an accuracy of 0.02mm to complete the calibration.

[0016] It should be noted that a linear displacement sensor with an accuracy of 0.01 mm is used as a contact measuring element. The sensor moves along the longitudinal marking at a speed of 5 mm / s, so that the probe is in contact with the side of the shoulder and neck from the acromion point (coordinate A1) to the spinous process point of the cervical vertebra (coordinate A2). The built-in recorder records the distance between the endpoints at a sampling frequency of 100 Hz, and obtains the lateral dimension of the shoulder and neck (recorded as 132.5 mm).

[0017] In another embodiment, an infrared ranging sensor (non-contact detection component) with an operating wavelength of 850nm and a measurement range of 0.1m-2m is simultaneously activated below the horizontal marking. It transmits detection signals at 2mm intervals and a frequency of 50Hz along the longitudinal direction of the cervical spine from the spinous process of the seventh cervical vertebra (coordinate B1) to the spinous process of the second cervical vertebra (coordinate B2), and captures the reflected coordinate feedback to form a dataset of 30 discrete sampling points.

[0018] It should be noted that, using the spinous process of the seventh cervical vertebra (coordinate B1) and the left and right acromion points (coordinates A1 left and A1 right) as fixed anchor points, the lateral dimensions of the left and right shoulders and neck (A1 left - A2 left = 131.8 mm, A1 right - A2 right = 133.2 mm) and the coordinates of 30 discrete sampling points are input into the three-dimensional coordinate fitting system. The least squares method is used for fitting (error ≤ 0.05 mm) to form a three-dimensional physiological contour of the shoulders and neck containing the coordinates of 20 key points of the shoulders and neck and the equation of the cervical curvature curve (Z = 0.002Y² + 0.15Y + 1200, unit mm). This contour data set is the personalized physiological data.

[0019] Optionally, generating personalized physiological data in step S1 includes: Locate the apex of the cervical lordosis and the transition point between the neck and shoulder in the cervical curvature contour, and symmetrically offset to both sides with the line connecting the two points as the axis to form the cervical support boundary line. Project the shoulder width dimension along the inclined direction of the neck support boundary line, so that the projected length of the shoulder width corresponds to the length of the neck support boundary line, which serves as the proportional reference for the spatial layout of the nine-zone filling cavity.

[0020] In this embodiment, all specific numerical parameters (such as coordinates, dimensions, angles, density, etc.) are exemplary settings. In actual operation, adjustments need to be made based on the actual physiological characteristics of the object being measured, the actual accuracy specifications of the equipment used, and the specific design standards of the product. The following is a description of the specific technical operation: A 3D contour scanner with an accuracy of 0.02 mm and a sampling density of 5 points / mm² was used to perform a secondary scan of the 3D physiological contour of the neck and shoulder (including the coordinates of 20 key points in the neck and shoulder, and the equation of the cervical curvature curve Z=0.002Y²+0.15Y+1200, in mm). The corresponding coordinate analysis software was used to extract the cervical lordosis vertex (coordinates P1: X=350mm, Y=350mm, Z=1592.5mm) and the neck-shoulder transition point (coordinates P2: X=350mm, Y=325mm) on the cervical curvature curve. Z=1486.25mm), the software automatically generates a line connecting P1 and P2 (axis L1, slope (1592.5-1486.25) / (350-325)=4.25), and symmetrically offsets it by 30mm to each side along a direction perpendicular to L1, forming the left neck support boundary line L2 (starting point P3: X=328mm, Y=325mm, Z=1486.25mm, ending point P4: X=328mm, Y=350mm, Z=1592.5mm) and the right neck support boundary line L3. (Starting point P5: X=372mm, Y=325mm, Z=1486.25mm, Ending point P6: X=372mm, Y=350mm, Z=1592.5mm); Using a contact measuring instrument with an accuracy of 0.01mm, the straight-line distance between the left and right acromion points (A1 left: X=300mm, Y=120mm, Z=1500mm; A1 right: X=400mm, Y=120mm, Z=1500mm) was measured, resulting in a shoulder width of 420mm. The shoulder width was then calculated using a projection calculation tool. The width dimension is projected along the inclined direction of the neck support boundary line L2 (at an angle of 35° with the horizontal direction). The projected length is calculated to be 344.7 mm according to the projection length formula (shoulder width dimension × cos35°). At the same time, the length of the neck support boundary line L2 (the straight-line distance between P3 and P4, calculated as 109.1 mm by coordinates) is measured, so that the shoulder width projection length (344.7 mm) and the neck support boundary line length (109.1 mm) form a 3.16:1 correspondence. This correspondence serves as the proportional benchmark for the spatial layout of the nine-zone filling cavity.

[0021] Preferably, step S2: determine the filling cavity volume and spatial layout of the nine zones of the airbag unit based on personalized physiological data, and form nine independent chambers without gas flow by processing flexible partitions and setting the position and size of the nine zones. Optionally, in step S2, by processing a flexible partition and setting the dimensions of nine partition positions, nine independent chambers without gas crossflow are formed, specifically as follows: The edge of the partition of the side-sleeping support chamber is made into a wave shape, and the direction of the wave is consistent with the shoulder contour when the human body is sleeping on its side. A strip-shaped reinforcing strip is set in the middle of the partition of the high and low pillow support chamber corresponding to the high and low pillow support. The strip-shaped reinforcing strip is arranged along the direction of the cervical curvature and forms a T-shaped structure with the main body of the partition. When the nine independent airbag units are separated to form independent chambers, the connection between the independent chamber partition and the outer frame is treated with a stepped interlocking process, wherein the interlocking depth is consistent with the thickness of the partition.

[0022] In this embodiment, based on personalized physiological data (including the three-dimensional contour of the neck and shoulders, the curvature curve of the cervical spine, and the projection ratio of the shoulder width), the three-dimensional cavity design software is launched. After the data file is imported into the system, the nine zones are divided according to the logic of "side sleeping support corresponds to the lateral area of ​​the neck and shoulders, high and low pillow support corresponds to the area directly below the cervical spine, and back head support corresponds to the area in contact with the back of the head". Then, based on the support force requirements of each area, the cavity boundary coordinates are input through the software's volume calculation function to obtain the volume value of each cavity and determine the spatial layout and volume parameters of the nine-zone filling cavities.

[0023] In another embodiment, a 0.8mm thick polyurethane elastic film is selected as the flexible partition material. The partition boundary dimension data output by the three-dimensional cavity design software is imported into a CNC laser cutting machine. The cutting accuracy is set to ±0.1mm, the cutting speed to 50mm / s, and the laser power to 80W. The polyurethane elastic film is then cut to obtain the partition blank. The pillow outer frame (ABS resin material, 3mm thick) is placed on the positioning fixture. According to the partition position coordinates set by the software (the distance between the partition and the inner side of the outer frame is 5mm, and the distance between adjacent partitions is distributed according to the cavity size), the partition blank is laid flat in the corresponding position inside the outer frame and fixed with positioning clamps.

[0024] It should be noted that for the edge of the partition blank corresponding to the side-sleeping support chamber, a CNC die-cutting machine is used and the wavy die-cutting head is replaced. First, the human side-sleeping shoulder contour scan image is imported into the die-cutting machine control system, the wave wavelength is set to 30mm and the wave height to 8mm, and the die-cutting machine is started to process along the edge of the partition to ensure that the wave direction is consistent with the shoulder contour direction when the human is sleeping on his side.

[0025] It should be noted that a nylon braided strip with a thickness of 1.2mm, a width of 15mm, and a length of 90mm is used as a strip reinforcement. This strip is placed in the middle of the partition blank corresponding to the high and low pillow support chamber. The hot melt welding machine is started. First, the placement direction of the reinforcement strip is adjusted according to the cervical curvature curve data so that it extends along the cervical curvature. Then, the welding temperature is set to 180℃, the welding pressure to 0.3MPa, and the welding time to 10s. The equipment is started to weld the reinforcement strip to the partition blank to form a T-shaped structure (the vertical side of the T-shape is the reinforcement strip, the horizontal side is the corresponding area of ​​the partition blank, and the center of the T-shaped structure is aligned with the center of the high and low pillow support chamber).

[0026] In another embodiment, the machined partition and outer frame are transferred to the CNC milling machine table. The milling parameters are set according to the partition thickness of 0.8mm (milling accuracy ±0.05mm, feed speed 30mm / min). Three stepped grooves (each groove width 5mm, groove depth 0.8mm) are machined on the inner side of the outer frame. Then, the connecting edge of the partition is punched with a punch press to process stepped protrusions that match the stepped grooves of the outer frame. Finally, the stepped protrusions of the partition are embedded into the stepped grooves of the outer frame and transferred to an ultrasonic welding machine. The welding frequency is set to 20kHz, the welding pressure to 0.2MPa, and the welding time to 8s. The equipment is started to complete the fixing of the partition and the outer frame, forming nine independent chambers without gas crossflow.

[0027] Preferably, step S3: adapt the airbag unit according to the functional requirements of side sleeping support, high and low pillow support and back head support of the independent chamber, and set an independent inflation and deflation channel for each airbag unit, and design a connection interface with the external inflation and deflation device at the end of the independent inflation and deflation channel. Optionally, in step S3, the airbag unit is adapted according to the functional requirements of independent chamber side-sleeping support, high / low pillow support, and back-of-the-head support. Specifically, the airbag unit adapted for side-sleeping support is as follows: Based on the shoulder width and shoulder and neck tilt angle in the side-lying position from the personalized physiological data, three tilt constraint lines are marked on the airbag deployment plane, where the angle between the constraint line and the side of the airbag is equal to the shoulder and neck tilt angle. The elastic restraint band is fixed along the restraint line, and the two ends of the restraint band are respectively connected to the corresponding anchor points on the upper and lower edges of the airbag unit. The anchor point spacing is set according to one-third of the shoulder width. When inflated, the elastic restraint band stretches along a preset angle as the airbag unit expands, guiding the airbag unit to form an inclined support surface that dynamically conforms to the contour of the neck and shoulders when sleeping on the side. The inclination angle of the support surface remains in a preset proportional relationship with the inclination angle of the neck and shoulders as the inflation volume changes.

[0028] The shoulder width, angle, size, and process parameters involved in this embodiment are all exemplary settings. The specific values ​​need to be flexibly adjusted according to actual personalized physiological data, material properties, and equipment specifications. The following is a description of the specific technical operation: Take the shoulder width (example value 420mm) and the shoulder and neck tilt angle when lying on your side (example value 25°) recorded in the personalized physiological data. Lay the cut side-lying support airbag blank (nylon elastic fabric, example size 120mm long × 80mm wide) flat on the CNC positioning workbench. Mark 3 tilt constraint lines on the airbag deployment plane using the coordinate positioning ruler (accuracy ±0.05mm) on the workbench. The first constraint line is 10mm away from the left edge of the airbag blank (example value), the second line is located at the horizontal center of the blank, and the third line is 10mm away from the right edge (example value). The three constraint lines are parallel and the spacing is 35mm (example value). The angle between each constraint line and the side of the airbag blank is set to 25° (consistent with the example value of the shoulder and neck tilt angle).

[0029] Select a spandex elastic restraint band with an example width of 10mm and an example thickness of 0.5mm. Use a hot-press molding process (example temperature 160℃, example pressure 0.3MPa, example time 8s) to process circular anchor points (example diameter 5mm, material is polyurethane wear-resistant block) on the upper and lower edges of the airbag blank. The anchor point spacing is set to 140mm according to one-third of the shoulder width (420mm÷3, this is the calculation result based on the example shoulder width). The anchor points on the upper and lower edges correspond one-to-one. Then, attach the elastic restraint band along the marked inclined restraint line. Use an ultrasonic welding device (example frequency 20kHz, example welding pressure 0.2MPa, example welding time 5s) to weld and fix the two ends of the restraint band to the corresponding anchor points on the upper and lower edges, respectively, to ensure that the restraint band and the restraint line are completely aligned.

[0030] The airbag with the restraint straps was inflated using a CNC air pump (indicative inflation flow rate 500 mL / min, pressure adjustment accuracy ±0.01 MPa). The inflation pressure was gradually increased from the example value of 0.1 MPa to the example value of 0.3 MPa. During the process, the restraint straps stretched along a preset 25° angle as the airbag expanded, guiding the airbag to form an inclined support surface. The tilt angle of the support surface was monitored in real time using an angle measuring instrument (accuracy ±0.1°) to ensure that for every 0.1 MPa increase in inflation pressure (this is the example pressure adjustment interval), the tilt angle of the support surface increased by 5° (this is the example angle change value), always maintaining a preset ratio of 1:5 with the shoulder and neck tilt angle (25°) (this ratio is the example relationship).

[0031] Optionally, in step S3, the airbag unit is adapted according to the functional requirements of independent chamber side sleeping support, high and low pillow support, and back head support. The specific airbag unit adapted for high and low pillow support is as follows: Based on the corresponding positions of the upper, middle, and lower cervical vertebrae in the personalized physiological data of the cervical physiological curvature, the inner cavity of the airbag unit is divided into three longitudinal adjustment sections, and a diaphragm with a one-way flow hole is set between each adjustment section. The inflation channel is designed with a bifurcated structure. The main channel connects to the middle adjustment section, and the two branch channels connect to the upper and lower adjustment sections respectively. The flow cross section of the branch channel is half that of the main channel. When inflating, the middle adjustment section is first inflated to 60% of the preset height, and then the upper and lower adjustment sections are inflated simultaneously through the branch channels, so that the height of the three sections changes in a coordinated ratio of 1:1.2:1 for the upper, middle and lower sections, forming a stepped support that conforms to the natural curvature of the cervical spine.

[0032] In this embodiment, the dimensions, process parameters, etc. are all exemplary settings, and should be flexibly adjusted according to actual data. The following is a description of the specific technical operation.

[0033] Take a blank of the high and low pillow support airbag (nylon elastic fabric, example length 100mm × width 70mm × height 50mm). Using a coordinate positioning instrument (accuracy ±0.05mm), mark two transverse dividing lines in the airbag cavity according to the positions of the upper, middle and lower cervical vertebrae (the first line is 20mm from the top, and the second line is 20mm from the first line), dividing it into three longitudinal adjustment sections. Cut a 0.3mm thick polyurethane film as a diaphragm (diameter 70mm), and machine a 1.5mm one-way flow hole in the center (flow direction is upward and downward adjustment section). Fix the diaphragm to the dividing line and seal it by hot melt welding (example temperature 170℃, pressure 0.25MPa, time 12s).

[0034] It should be noted that a 4mm inner diameter PVC hose is used to make the inflation channel. The three-way connector is designed as a branch structure. The main channel (30mm long) is welded to the inflation port of the middle adjustment section (4mm in diameter). The two branch channels (25mm long, 2mm inner diameter, with a flow cross-section of 1 / 2 of the main channel) are welded to the upper and lower adjustment section inflation ports (2mm in diameter), respectively. After welding, the airtightness is tested with an airtightness tester (example test pressure 0.3MPa, pressure holding for 30s).

[0035] It should be noted that a CNC air pump (example pressure 0.05-0.5MPa) is connected to the main inlet of the branch channel. First, the middle adjustment section is inflated at 0.1MPa and 200mL / min. When the laser rangefinder detects that the height of the middle section reaches 60% (12mm) of the preset value (20mm), the flow rate is switched to 100mL / min, and the gas is diverted to the branch channel to inflate the upper and lower sections simultaneously. Inflation is stopped when the heights of the three sections are equal to 1:1.2:1 (example: upper 16.67mm, middle 20mm, lower 16.67mm).

[0036] Optionally, in step S3, the airbag unit is adapted according to the functional requirements of independent chamber side sleeping support, high and low pillow support, and back head support. Specifically, the airbag unit adapted for back head support is as follows: Based on the elliptical fitting data of the posterior brain contour in the personalized physiological data, an arc-shaped guide strip parallel to the major axis of the ellipse is set on the inner side of the airbag unit, and the spacing between the guide strips is one-quarter of the minor axis of the ellipse. One end of the guide strip is fixed to the center of the top of the airbag, and the other end extends radially to both sides to the edge of the airbag. The extension length decreases proportionally as the distance from the center increases. During inflation, the gas flows along the gaps between the guide strips. Under the constraint of the guide strips, the main support area matching the major axis of the ellipse is first formed in the middle of the airbag unit. As the inflation volume increases, the secondary support areas that fit the temporal region are naturally formed on both sides of the airbag unit, maintaining the pressure ratio of the main and secondary support areas at 3:1.

[0037] The ellipse fitting data, guide strip dimensions, process, and inflation parameters involved in this embodiment are all exemplary settings. Specific adjustments need to be made flexibly based on the actual posterior head contour data and material properties. The following is a description of the specific technical operations: In one embodiment, using the ellipse fitting data of the posterior head contour from personalized physiological data (example major axis 120mm, minor axis 80mm), the pre-cut posterior head support airbag blank (nylon elastic fabric, example dimensions 130mm long × 90mm wide) is laid flat on a CNC coordinate positioning worktable. The worktable's built-in coordinate positioning instrument (accuracy ±0.05mm) marks the guide strip installation baseline on the inside of the airbag. Polyurethane elastic guide strips, 5mm wide and 0.8mm thick, are selected, and the spacing between the guide strips is set according to one-quarter of the minor axis of the ellipse (80mm ÷ 4 = 20mm), resulting in a total of 5 guide strips. One end of the guide strip is fixed to the center of the top of the airbag (corresponding to the center coordinates of the ellipse) by hot melt welding (example temperature 165℃, pressure 0.2MPa, welding time 8s). The other end extends radially to both sides to the edge of the airbag. The central guide strip extends for 60mm (consistent with half of the major axis of the ellipse), and the extension lengths of the adjacent guide strips on both sides decrease by 10mm respectively (50mm and 40mm). The extension length decreases by 10mm per increment as the distance from the center increases. After welding, the fixing strength of the guide strip is verified by a tensile tester (example test force 50N, holding time 10s).

[0038] In another embodiment, a CNC inflation pump with pressure monitoring function (example inflation flow rate 200 mL / min, pressure adjustment accuracy ±0.01 MPa) is used. The inflation interface is connected to the airbag inflation port (4 mm in diameter, located at the center of the bottom of the airbag). The inflation pressure is set to gradually increase from 0.08 MPa to 0.2 MPa. During inflation, the gas flows along the 20 mm gap between the guide strips. The pressure is monitored in real time by pressure sensors (accuracy ±0.005 MPa, 3 in total, 1 located in the middle of the airbag corresponding to the major axis of the ellipse, and 2 located on both sides corresponding to the temporal region) arranged on the outside of the airbag. Under the constraint of the guide strips, the middle of the airbag first forms a main support area that matches the major axis of the ellipse (120 mm). As the inflation volume increases, the two sides naturally form a secondary support area that fits the temporal region. When the inflation pressure reaches 0.2 MPa, the pressure of the main support area stabilizes at 0.18 MPa and the pressure of the secondary support area stabilizes at 0.06 MPa, maintaining a pressure ratio of 3:1 between the main and secondary support areas.

[0039] Optionally, in step S3, when setting an independent inflation / deflation channel for each airbag unit, the three-dimensional path of the channel is planned according to the position coordinates of the nine zones of the airbag unit: The side-sleeping support airbag has an L-shaped channel along the outer edge of the cavity, the high and low pillow support airbag has a straight channel along the tangent of the cervical spine curvature, and the back of the head support airbag has a channel that extends obliquely downward from the center of the cavity. The connection points between the channel and the airbag are all located on the vertical line of the geometric center of each airbag. The channel is equipped with a sleeve that matches the thickness of the flexible partition where it passes through the partition. The outer wall of the sleeve and the partition are integrally formed by molding.

[0040] In this embodiment, the airbag position coordinates, channel dimensions, and process parameters are all exemplary settings. Specific adjustments need to be made based on the actual layout and material specifications of the nine zones. The following is a detailed description of the technical operations: In one embodiment, the geometric center coordinates of the nine-zone airbag unit are read using a coordinate positioning instrument (accuracy ±0.05mm): left side-sleeping support airbag: X1=280mm, Y1=220mm, Z1=1520mm; X2=280mm, Y2=300mm, Z2=1520mm; right side-sleeping support airbag: X3=420mm, Y3=220mm, Z3=1520mm; X4=420mm, Y4=300mm, Z4=1520mm; high and low pillows. Support airbags: X5=350mm, Y5=250mm, Z5=1530mm; X6=350mm, Y6=300mm, Z6=1530mm; X7=350mm, Y7=350mm, Z7=1530mm; Back-of-the-head support airbags: X8=350mm, Y8=400mm, Z8=1515mm; X9=350mm, Y9=450mm, Z9=1515mm). Based on the above coordinates, the direction of each channel is determined using three-dimensional path planning software.

[0041] It should be noted that an independent inflation / deflation channel is made of a 4mm inner diameter and 1mm wall thickness polyvinyl chloride (PVC) flexible tube. The channel of the side-sleeping support airbag is L-shaped along the outer edge of the corresponding chamber (5mm from the outer wall of the chamber), with a horizontal section length of 25mm (along the Y-axis) and a vertical section length of 20mm (along the negative Z-axis), and a curvature radius of 8mm at the corner. The channel of the high-low pillow support airbag is arranged in a straight line along the tangent of the cervical curvature (calculated based on the cervical curvature curve Z=0.002Y²+0.15Y+1200mm, with the tangent making an angle of 30° with the horizontal direction), with a channel length of 30mm, and both ends extending to the airbag and the external interface respectively. The channel of the back-of-the-head support airbag extends obliquely downward from the center of the chamber (coordinates X8 / X9, Y8 / Y9, Z8 / Z9), with an inclination angle of 45° (with an angle with the negative Z-axis), and a length of 35mm.

[0042] In another embodiment, the connection points between the channel and each airbag are located on the vertical line of the geometric center of the corresponding airbag (along the Z-axis direction), and the connection points are 8mm away from the bottom of the airbag. Where the channel passes through the flexible partition (thickness 0.8mm), a polyurethane sleeve (inner diameter 5mm, outer diameter 6.6mm, length 0.8mm, matching the thickness of the partition) is installed. After the sleeve is put on the outside of the channel, a molding process (temperature 180℃, pressure 0.3MPa, time 15s) is used to integrally form the outer wall of the sleeve with the flexible partition, ensuring that there is no gap between the partition and the sleeve.

[0043] Optionally, the connection interface for connecting to an external inflation / deflation device designed at the end of the independent inflation / deflation channel in step S3 includes: The end face of the airbag unit interface for side sleeping support is set with a boss height corresponding to the shoulder width data; the inner wall of the airbag unit interface for high and low pillow support is set with a spiral guide corresponding to the cervical curvature; and the outer periphery of the airbag unit interface for back head support is set with the number of teeth corresponding to the minor axis of the back head contour ellipse. The corresponding position of the plug of the external inflation / deflation device is provided with matching grooves, spiral grooves and teeth, and the sealing structure inside the interface of the external inflation / deflation device is designed in conjunction with the maximum inflation pressure of the airbag unit.

[0044] The parameters in this embodiment are exemplary settings and need to be adjusted according to individualized physiological data. The following is a description of the specific technical operations: Made of ABS resin, nine connection interfaces (corresponding one-to-one with the airbag unit) are machined on a CNC lathe (accuracy ±0.05mm). The end face of the side-sleeping support airbag interface is machined with a circular boss 8.4mm high and 5mm in diameter, based on the shoulder width example of 420mm (each 100mm corresponds to a 2mm boss height). The inner wall of the high-low pillow support airbag interface is machined with a single-line spiral pattern with a lead of 10mm, a helix angle of 30°, and a depth of 0.5mm, based on the tangential direction corresponding to the cervical curvature, using a thread milling cutter (cutting edge accuracy ±0.01mm). The outer periphery of the back-of-the-head support airbag interface is machined with eight rectangular teeth, each 2mm high and with a tooth pitch of 4.71mm, based on the back-of-the-head ellipse minor axis example of 80mm (each 10mm corresponds to one tooth), using a gear hobbing machine (accuracy grade 6). The external inflation / deflation device plugs (ABS material) are CNC-machined with matching structures: the side-sleeping plug has an 8.4mm deep groove, the high / low headrest plug has a 10mm lead spiral groove, and the back-of-the-head plug has 8 toothed grooves, with the gap controlled between 0.01-0.02mm. A Shore 60-degree silicone sealing ring is installed inside the interface. The compression is set to 1.2mm (30% deformation rate) based on the maximum inflation example value of 0.3MPa for the airbag. After installation, an airtightness tester (0.4MPa, pressure holding for 30s) is used, and the allowable leakage is ≤0.01MPa / min.

[0045] Preferably, in step S4: nine independent airbag units are embedded into corresponding independent chambers, and the flexible partition is fixed to the edge of the airbag unit by stitching or bonding, and the independent inflation and deflation channels are connected to the inflation port of the airbag unit to form an overall support structure. Of particular importance is that, in step S4, connecting the independent inflation / deflation channel to the airbag unit inflation port specifically involves: An annular groove is machined inside the air inlet, and retractable elastic claws are set at the end of the channel. There are 3 claws, which are evenly distributed along the circumference of the channel. During docking, insert the end of the channel into the inflation port, press the claw to retract it, and release the claw after it is in place. The claw will spring into the slot to secure it. The contact surface between the claw and the slot is tilted inward.

[0046] The dimensions and process parameters in this embodiment are exemplary settings and need to be adjusted according to the specifications of the airbag and chamber. The following is a description of the specific technical operations: In one embodiment, nine independent airbag units (two left-side sleeping support airbags, two right-side sleeping support airbags, three high-low pillow support airbags, and two posterior head support airbags) are embedded into corresponding independent chambers. Calibration is performed using a coordinate positioning ruler (accuracy ±0.05mm) to ensure that the geometric center of each airbag unit coincides with the geometric center of the chamber (corresponding coordinates: left-side sleeping airbag X=280mm / Y=220mm, X=280mm / Y=300mm; right-side sleeping airbag X=420mm / Y=220mm, X=420mm / Y=300mm; high-low pillow airbag X=350mm / Y=250mm, X=350mm / Y=300mm, X=350mm / Y=350mm; posterior head airbag X=350mm / Y=400mm, X=350mm / Y=450mm). In another embodiment, a hot-melt bonding process (temperature 170℃, pressure 0.25MPa, time 10s) is used to fix the flexible partition (thickness 0.8mm) to the edge of the airbag unit, with a bonding width of 5mm, ensuring that the partition and the edge of the airbag fit together without gaps. An annular groove (groove width 2mm, groove depth 1.5mm, distance from the end face of the inflation port) is machined on the inner side of the inflation port (diameter 6mm, located at the center of the bottom of the airbag) of each airbag unit using a CNC lathe (machining accuracy ±0.03mm). At the end of the independent inflation / deflation channel (inner diameter 4mm, outer diameter 6mm), three retractable elastic claws (each claw 3mm long, 1mm thick, evenly distributed at 120° along the circumference of the channel) are made of nitrile rubber. The claws and the end of the channel are integrally formed by injection molding, with the contact surface of the claws (the surface that fits with the groove) inclined inward at 15°.

[0047] During docking, align the end of the channel (outer diameter 6mm) with the airbag inflation port (inner diameter 6mm) and insert it to a depth of 5mm (until the claw reaches the slot position). Use a special tool (pressure 0.1MPa) to press the claw to make it radially retract to a diameter of 5mm. After it is in place, remove the tool. The claw will spring into the annular slot (claw extension 1.5mm, matching the slot depth) under its own elasticity to achieve fixation. Finally, verify the docking strength through a tensile tester (test force 50N, pressure holding 10s) to ensure that there is no detachment and to form an overall support structure.

[0048] Preferably, in step S5: the memory foam composite fabric is cut according to the outer contour of the overall support structure and covered on the outside of the support structure. The memory foam composite fabric is then processed using a hot-pressing molding process to make the memory foam composite fabric conform to the physiological curvature of the cervical spine to form a curved pillow.

[0049] Optionally, when using the hot-pressing shaping process to process the memory foam composite fabric in step S5, a detachable shaping frame that matches the cervical spine physiological curvature in the personalized physiological data is placed between the memory foam composite fabric and the overall support structure. The shaping frame has ventilation holes, and the opening position of the ventilation holes avoids the protruding area of ​​the overall support structure. During hot pressing, the shaping frame and the memory foam composite fabric are subjected to force simultaneously. After shaping is completed, the pressure is released first, and then the shaping frame is pulled out from between the memory foam composite fabric and the overall support structure along the pre-set disassembly seam.

[0050] In this embodiment, a 3D contour scanner (scanning accuracy ±0.1mm, sampling density 10 points / mm²) is used to collect the outer contour data of the overall support structure (length 450mm × width 300mm × height 120mm, including the raised area of ​​the high and low pillow support chamber). The data is then imported into a CNC cutting machine (cutting accuracy ±0.5mm, cutting speed 30mm / s). A 20mm thick memory foam composite fabric (40-count cotton on the surface and polyurethane memory foam on the bottom, density 40kg / m³) is selected, and the fabric blank is cut according to the outer contour dimensions (leaving a 5mm seam allowance).

[0051] In another embodiment, a detachable, moldable frame is fabricated that matches the physiological curvature of the cervical spine (based on the curve equation Z=0.002Y²+0.15Y+1200mm). The frame is made of ABS resin (2mm thick) and is processed according to the curvature using a CNC bending machine (bending accuracy ±0.1°). Ventilation holes (3mm diameter, 15mm spacing) are made on the frame using a CNC drilling machine (drilling accuracy ±0.1mm). The hole positions avoid the protruding area of ​​the high and low pillow support chamber of the overall support structure (corresponding coordinates X=350mm / Y=250-350mm / Z=1530mm).

[0052] In another embodiment, a pre-cut memory foam composite fabric is placed over the outside of the overall support structure. A pre-processed, detachable, moldable frame is placed between the inside of the fabric and the support structure, ensuring that the curvature of the frame perfectly matches the physiological curvature of the cervical spine. The assembly is placed in a CNC hot press molding machine (hot pressing accuracy ±0.1mm), and the hot pressing parameters are set as follows: temperature 80℃, pressure 0.2MPa, and holding time 150s. During the hot pressing process, the frame and the memory foam composite fabric are subjected to force synchronously. After molding, the pressure is first controlled to release to 0MPa, and after the temperature drops to room temperature (25℃), the frame is pulled out from between the fabric and the support structure using special tweezers along the pre-set disassembly seam (5mm wide, located at the edge of the frame corresponding to the seam allowance of the fabric), ultimately forming a curved pillow that conforms to the physiological curvature of the cervical spine.

[0053] Please see Figure 2This diagram illustrates the nine-zone dimensions of a custom pillow, arranged in a three-row, three-column layout. Each zone is labeled with its specific dimensions (unit: cm). These zone dimensions are directly related to the spatial layout of the pillow's nine-zone filling cavity. Different sizes accommodate different support functions: the central 6.2cm zone corresponds to the high-low pillow support area in the middle of the cervical spine; the surrounding 9.1cm, 9.3cm, and other zones provide transitional support for the neck and shoulders when sleeping on one's side; the larger bottom zones, such as 15.9cm and 16.3cm, correspond to the main support area for the shoulders when sleeping on one's side; and the 11.3cm, 10.9cm, and 11.5cm zones provide auxiliary support for the back of the head or when sleeping on one's side. These dimensions are determined based on personalized physiological data and are key parameters for achieving zoned airbag adaptation, fabric shaping, and ultimately, a custom pillow that conforms to the physiological curvature of the human neck and shoulders.

[0054] Please see Figure 3 This is a schematic diagram of the nine-zone airbag structure of a custom pillow, arranged in a three-row, three-column layout. The nine zones are distinguished by different colors and labeled ①-⑨. Zones ①, ②, ③, ⑦, ⑧, and ⑨ are for side sleeping, providing lateral support for the neck and shoulders; zones ④ and ⑥ are for adjustable pillow height to accommodate the upper and lower parts of the cervical spine; and zone ⑤ is for back-of-the-head support, conforming to the contours of the back of the head. Each zone corresponds to an independent airbag, equipped with an independent inflation / deflation channel and air pressure control device (the air volume can be adjusted via a manual air pump, electric control unit, or mobile app). Each airbag can adopt a flat structure such as near-rectangular, trapezoidal, or arc-shaped (e.g., airbag ④ can be designed as an arc shape to fit the neck) according to the support area. After inflation, it can change height to meet the different head, neck, and shoulder height requirements of various preset sleeping positions, such as back sleeping and side sleeping, achieving customized support that matches posture.

Thus, all variations falling within the meaning and scope of the equivalents of the application are intended to be included within the invention.
