[0003] The existing functional pillow core mostly uses fixed partition or single material deformation to provide support, which is difficult to dynamically adapt to the body position change during sleep and the contour and stiffness difference of different users' head and neck. For example, the fixed partition spring pillow cannot provide ideal support when lying on the back and side, and the material such as memory cotton responds slowly and cannot real-time fit the stiffness difference between the skull and soft tissue, affecting the comfort and health support effect.

[0011] Preferably, the substrate and the base support part are in a split structure and are fixed through a connecting structure; or the substrate and the base support part are in an integrated structure, and the substrate constitutes the main body of the base support part.

[0012] In a second aspect, the present application provides a method for forming an adaptive head and neck support surface, characterized by comprising the following steps: providing a pillow core support system as described in the first aspect; contacting the head and neck of a user with the initial plane of the support array; discretizing the macroscopic non-uniform pressure distribution caused by the contour and stiffness differences of the head and neck into micro loads acting on each support unit through the support array; each support unit generates its own independent and differentiated vertical compression deformation in response to the micro load; thereby mapping the macroscopic pressure distribution to the micro height distribution difference of the support array surface, so as to autonomously reconstruct it from the uniform initial plane to the personalized support surface adapted to the three-dimensional contour of the head and neck of the user. Preferred solutions

[0013] Furthermore, the base of the independent support unit can have a circular, polygonal, or irregular shape composed of curves and straight lines, such as a cylindrical tube, rectangular tube, or triangular prism tube structure.

[0014] Furthermore, the shape of the hole structure on the substrate of the integrated support unit is adapted to the cross-sectional shape of the base, for example, a cylindrical hole, a square hole, or a triangular prism hole is adopted.

[0015] Furthermore, the support units are fixed together by a mechanical interlocking structure to form an integral array.

[0016] Furthermore, the mechanical interlocking structure is a structure that achieves connection through physical shape coupling between components.

[0017] Furthermore, the support units are arranged in a dense arrangement.

[0018] Furthermore, the basic support portion is a structure that is rigidly connected to the bottom of the support unit or integrally formed.

[0019] Furthermore, the basic support section is provided with functional auxiliary structures.

[0020] Furthermore, the cross-sectional shape of the substrate extension is a regular or irregular geometric shape that enables a stable engagement function.

[0021] Furthermore, the support unit array is configured to generate significant differences in compression when it bears the weight of a typical adult head and is located at different positions on the head contour due to differences in head contour height and tissue stiffness, thereby effectively forming the three-dimensional support surface.

[0022] Furthermore, the multiple support units are fixed to each other through a connecting structure to form an integral array; the connecting structure is configured to maintain the overall structural stability of the array while allowing each support unit to be compressed independently, and to effectively prevent the array edges from collapsing during use.

[0023] Furthermore, the substrate or basic support portion is connected to the flexible support frame through a mechanical interlocking structure.

[0026] Further, the inner lining profile of the flexible support frame is adapted to the shape of the side surface of the array of support units and closely fits therewith.

[0027] Further, the outer side surface and the top surface of the flexible support frame are made of soft elastic material, which is friendly to human skin and free of harmful volatile substances. Innovative mechanism

[0028] The core innovative mechanism of the present application is that, by using a dense array of support units with identical structures, when the user's head contacts, the curved contact cover on the top of each unit locally disperses and directs the pressure to axial load; by strictly constraining the deformation of each support unit to the vertical direction, it ensures that the load is independently and accurately converted into vertical deformation, thereby directly mapping the macroscopic pressure distribution caused by the difference in head profile and tissue stiffness into the microscopic height difference of the array surface, so that the support plane can automatically reconstruct into a three-dimensional curved surface that matches it.

[0029] The specific working mechanism is as follows, 1. Initial homogeneous state establishment: all support units are at the same height plane, forming a completely unified initial support surface; 2. Multiple pressure sensing and response: the head bone protruding points exert greater pressure on the corresponding position units, triggering significant compression deformation; at the same time, the geometric characteristics of the natural curved surface of the head bone guide the pressure distribution, further optimizing the support form; 3. Self-adaptive curved surface self-forming: the array automatically deforms according to the pressure distribution, forming appropriate depressions at rigid support points and maintaining relative convexity in soft tissue support areas, perfectly fitting the natural contour of the head bone; 4. Dynamic real-time tracking and adjustment: as the sleeping posture changes, the support curved surface is reconstructed in real time, always maintaining the optimal support state that matches the current posture; Beneficial effects

[0030] Compared with the prior art, the present application has the following outstanding advantages, 1. Structural diversification and manufacturing flexibility: provides multiple structural forms and connection methods, adapts to different production processes and cost requirements, and facilitates large-scale production and product differentiation; 2. True full-adaptive support capability: completely abandoning any preset zoning concept, it automatically forms the optimal support curved surface according to the unique head profile and stiffness distribution of the user, achieving truly personalized adaptation; 3. Extremely simplified manufacturing process system: all core support unit structural parameters are completely consistent, and an integrated design scheme is provided, greatly simplifying supply chain management, production process flow and quality control system, significantly reducing large-scale production costs; 4. Fast response dynamic characteristics: the elastic element is based on its physical deformation principle (such as Hooke's law), and its intrinsic response speed is much better than that of traditional slow rebound materials relying on viscoelastic deformation and recovery, which can accurately track the subtle changes of sleep posture in real time; 5. Excellent durability and structural stability: the support unit forms a whole array through mechanical interlocking structure, and the structural connection mode cooperates with the design of the elastic element, effectively disperses the local stress, and significantly improves the overall durability of the system with low performance decay rate; 6. Targeted edge safety protection: through the physical isolation of the flexible support frame and the lateral hard structure of the support array, the edge bruise risk of the micro independent support array is fundamentally eliminated, and the edge safety that the traditional pillow and the whole support core do not have is provided.

[0039] The application will be further described in detail below with reference to the accompanying drawings.

[0040] Firstly, the base support provides a stable installation base and necessary boundary conditions for the core adaptive support array, In its basic form, it can be a plate-like structure with certain rigidity, and to achieve the final function of the pillow core and the user experience, the base support can be designed as follows: 1. Stiffness and cushioning composite structure: rigid or semi-rigid materials (such as engineering plastics) can be used as the core layer to ensure that the deformation of the support unit array mainly occurs within its own vertical stroke, rather than uncontrolled collapse of the base. To improve comfort, a cushioning layer (such as high-density foam) can be added to the lower surface to absorb minor vibrations; 2. Overall support height adjustment and stability: One of the main functions of the base support is to adjust the overall height of the pillow core and ensure its stability. To achieve height adjustment, a set of shims with different thicknesses can be replaced, or inflatable cavities can be provided in the base support to fine-tune its overall thickness by changing the air pressure. This adjustment function allows users to find the most suitable pillow height according to their own height, shoulder width, and sleeping habits (such as sleeping on their back or side), ensuring that the spine is in a natural straight position during sleep; at the same time, the bottom surface of the base support should be designed as a non-slip interface with high friction coefficient, or through its own weight and structural design, effectively inhibiting harmful sliding of the pillow core relative to the bed surface during sleep, providing a stable support experience for users; 3. System function integration: The base support can serve as a system integration platform, with interfaces reserved inside or on the bottom surface for additional modules such as controls and sensors. These additional functions, combined with adaptive support, form a more complete sleep solution, but their implementation relies on the core support structure.

[0041] Secondly, the mechanism of "independent vertical movement" of the support unit is described, The key of the application is to realize the independent vertical movement of each support unit and prevent it from tilting or interfering with each other. The following are several feasible implementation methods, but the protection scope of the application is not limited thereto: 1. Guiding sleeve type (exemplary embodiment): As shown in the drawings, the guiding connection part of the contact cover cooperates with the inner wall of the base with a small gap to form a sliding guiding mechanism. It can be understood that the guiding connection part can also be sleeved outside the base cylinder and cooperates with the outer wall of the base to realize the guiding function. This is a specific and preferred way to realize vertical constraint; 2. External guide rail type: In another embodiment not shown, the guiding function can be realized by setting guide rails or guide grooves on the outer wall of the base and cooperating with the corresponding structures on the base or base plate of the adjacent support unit; 3. Built-in rolling body type: Micro balls or rollers can also be arranged between the contact cover and the base to convert sliding friction into rolling friction to realize smoother guiding; 4. Material self-guiding type: In some designs, the elastic element itself (such as a plate spring or flexible polymer column with a specific structure) or its specific connection with the base and the contact cover can provide sufficient bending stiffness to constrain the movement direction without the need for independent physical guide rails.

[0042] It should be emphasized that no matter which specific structure or combination thereof is adopted, as long as it realizes the core function of "restricting the movement of the support unit in the vertical direction", it falls within the protection scope of the application. The application claimed is the core idea of realizing the independent vertical movement of each support unit through structural design.

[0043] The contact cover is a key component for realizing comfortable contact and force transmission. The top part is a smooth curved surface suitable for the head and neck curvature of the human body, and the lower part is provided with a dedicated guiding connection part.

[0044] The core role of the guiding connection part is to work with other components of the system (elastic element and / or base) to achieve two basic goals: 1. Force transmission and stroke definition: Ensure that the head pressure can be effectively transmitted to the elastic element, and limit the vertical movement range of the contact cover within a reasonable interval; 2. Vertical guiding and stabilization of movement: By adapting to the inner and outer contours of the base (or base plate hole), an effective guiding mechanism is formed to suppress lateral displacement and shaking.

[0045] Further, the connection method between the support units is described: The support units are fixed to each other by a mechanical interlocking structure to form a whole array. The mechanical interlocking structure refers to all ways of connecting through physical shape coupling between components, including but not limited to welding connection, buckle connection, mortise and tenon connection and any combination thereof. The core is that the overall structural stability of the array can be maintained while allowing each support unit to be independently vertically compressed without relying on external connecting parts.

[0046] The size of the support unit is the key to achieving the best adaptive effect, The selection of the center distance of the support unit in the range of 8mm to 15mm is based on the comprehensive trade-off between support effect and manufacturing cost, which can ensure that the support array has sufficient simulation accuracy for complex contours while controlling the manufacturing cost within a reasonable range: 1. When the center distance is less than 8mm, the support point density is too high, which intensifies the deformation interference between adjacent support units, weakens the independence of the units, and affects the accuracy of adaptive curved surface generation; at the same time, the significant increase in the number of units leads to a sharp rise in manufacturing difficulty and cost; 2. When the center distance is greater than 15mm, the support point density is insufficient, which leads to a decrease in the discretization simulation accuracy of the support array for the contour of the head and neck, and cannot form a continuous and smooth adaptive curved surface, which significantly affects the comfort and health support effect.

[0047] The range of the elastic body performance parameters (30% to 60% deformation under a pressure of 30N to 60N) is based on the biomechanical characteristics of the human head and neck: 1. This pressure range covers the typical pressure distribution of the head and neck of most adult users (body weight 50-100 kg) in a static lying position acting on the pillow core support surface; 2. This deformation range ensures that the support unit can produce an absolute compression difference of not less than 15mm when subjected to typical pressure. This height difference range is confirmed by biomechanical research as necessary for effectively fitting the natural physiological curvature of the human head and neck and providing personalized support.

[0048] Finally, the connection structure of the flexible support frame and the support array is described, The flexible support frame is detachably or fixedly connected with the substrate or base support part of the support array through a mechanical interlocking structure; The mechanical interlocking structure includes a first interlocking part provided on the substrate, and a second interlocking part provided on the inner side of the frame and matched with the first interlocking part; In a preferred embodiment, the first interlocking part is an extension horizontally extending from the edge of the base plate, and the second interlocking part is a snap groove provided inside the frame for accommodating the extension. During assembly, the extension is precisely snapped into the groove, thereby achieving a stable connection between the support array and the frame. The extension can be a regular or irregular geometric shape that can achieve the function of stable snapping.

[0049] It is emphasized that the present application does not limit the specific form of the mechanical interlocking structure. The extension and the snap groove are only a preferred way. Any structure that can achieve stable connection between the base plate and the frame through physical shape coupling, such as a set of matching buckles, a sliding groove and a sliding block, etc., falls within the scope of protection of the present application. Embodiment 1: Independent support unit implementation

[0050] As shown in Figures 1-2 , the adaptive pillow of the present application is composed of a closely arranged support array of a plurality of identical independent support units. Each independent support unit includes three core components: 1. Base: provides stable basic support and fixing function, and its cross-sectional shape can be circular, polygonal, etc., such as cylindrical, rectangular or triangular prism structure; 2. Elastic element: provides main elastic restoring force and compression stroke; 3. Contact cover: provides a comfortable interface for contacting the human body, with a convex curved structure on the top and a guide connection part on the bottom.

[0051] First, the support units are fixed to each other by a mechanical interlocking structure to form a whole array. The mechanical interlocking structure is a shape-coupled mechanical interlocking structure, and the support units are arranged in a dense arrangement; Subsequently, the assembled support array is fixed to an independent base plate through the connection structure (such as buckles or adhesives) at the bottom of the base. Here, the base plate and the basic support part are integrated, and the base plate is an independent rigid or semi-rigid bottom plate in this embodiment, which can be made of engineering plastics, composite materials, etc.; Finally, the basic support part integrated with the support array is assembled with the second interlocking part (such as a snap groove) of the flexible support frame through the first interlocking part (such as an extension) at the edge of the basic support part, thereby completing the integration of the whole pillow support system. Embodiment 2: Integrated support unit implementation

[0052] As shown in Figure 3 , the integrated support unit adopts an integrated design of base plate and hole structure. On a base plate with a certain thickness, a hole type that matches the shape of the base is directly machined, such as a cylindrical hole, a square hole or a triangular prism hole, etc., for accommodating the elastic element and the contact cover: In this embodiment, the substrate directly serves as the base support part, and the integrally formed substrate-base support part has sufficient thickness, rigidity and structural integrity to provide a stable foundation for all the support units. The material is preferably an engineering plastic integrally formed by injection molding; This design simplifies the manufacturing process, reduces the number of parts, and reduces assembly costs while maintaining the independent movement function of each support unit; Similarly, the integrated support array (whose substrate is the base support part) is connected and fixed by the first interlocking part of its edge with the second interlocking part of the flexible support frame, forming a complete product. Embodiment 3: Specific parameter scheme for realizing adaptive function

[0053] In a pillow system using a structure and base support part as described in Embodiment 1 or 2, the base of the support unit is a cylindrical structure with an outer diameter of 10 mm. It can be understood that a base outer diameter in the range of 8 mm to 12 mm, or a support unit center distance in the range of 8 mm to 15 mm, can achieve the purpose of the present application; The elastic element is a micro-spiral compression spring with a free height of 25 mm and a stiffness coefficient of 0.42 N / mm. This parameter combination has been verified by biomechanics, so that the spring can have a compression deformation of 40%-50% of its free height when subjected to a pressure of about 40N-50N, thereby ensuring that a significant compression difference can be generated to effectively form a three-dimensional support surface.

Example 5: Performance verification based on deformation trace visualization

[0056] To verify the technical effect of the pillow core support system of the present application, the following intuitive and easy-to-implement test method can be used, which can solidify the instantaneous curved surface shape under compression into observable permanent traces, and is called deformation trace method: 1. On the outer surface of the guide connecting part of all support units contacting the cover, a thin and soft, easily scraped indicating layer (such as water-soluble pigment or marker wax pencil) is uniformly applied in advance, then a standard test head mold is placed on the support array, and after a few seconds, it is removed; 2. Macroscopic morphology observation: After removing the head mold, observe the distribution of the annular scraping traces left on the guide connecting part of all support units contacting the cover of the support array, which directly reproduces the boundary and shape of the instantaneous concave curved surface formed when the head mold is pressed down; the areas with dense traces and large deformation correspond to the protruding support points of the head mold, and the areas with shallow and sparse traces or no traces correspond to the concave parts or non-contact areas of the head mold, which directly proves the existence of the adaptive three-dimensional support surface; 3. Microscopic deformation quantification: Use a vernier caliper to measure the vertical distance from the vertex of each support unit to the lowermost end of the scraping trace on its guide connecting part, which is the actual compression deformation of the unit under the pressure of the head mold; by sampling and measuring the units at different positions in the array, the differential distribution of the deformation can be verified, and it can be confirmed whether it is within the preset range of 30%-60% free height. Example 6: Description of deformation trace test method

[0057] The support array adaptive surface verification method is to verify and measure the ability of the support array to form an adaptive three-dimensional surface under load and the independent deformation of each unit through visual means: 1. Pretreatment: On the area where the head mold is supported, as well as the edge area of this area, the outer surface of the guide connecting part of the support unit is coated with a thin and uniform easily scraped indicating layer; 2. Loading: Place the standard test head mold gently on the center of the treated support array, ensuring stable contact; 3. Unloading and solidifying traces: Remove the test head mold. At this time, the support units that have been in contact and friction with the inner wall of the hole of the base / substrate during compression will leave clear annular scraping traces on the indicating layer. The distribution of these traces permanently records the curved surface shape under compression; 4. Data analysis: a. Qualitative analysis: Observe the entire array, the macroscopic distribution of the traces is the direct proof of the adaptive curved surface formed; b. Quantitative analysis: Using a measuring tool (e.g. vernier caliper), measure the distance from the lowest end of the scratch mark of the designated unit to the vertex of the contact cover, and obtain the compression deformation data of the unit.
