Description

Technical Field

[0001] This invention relates to the field of shoe sole technology, specifically to a shock-absorbing and supportive shoe sole and shoe. Background Technology

[0002] With socio-economic development and the continuous improvement of people's living standards, more and more people are paying attention to health and participating more in sports and fitness in their daily lives. During activities such as running, due to inertia, the sole of the shoe experiences downward pressure from the body's weight and a counter-impact force from the ground (generally equivalent to 3 to 5 times the body weight) at the moment of impact. This impact can easily cause damage to the knee and / or ankle joints. Therefore, shoes are footwear designed to protect the legs and feet from injury, and the cushioning function of shoes is extremely important and necessary.

[0003] Many shoes on the market with cushioning features improve the material or structure of the sole. For example, in terms of sole material, they use foamed thermoplastic polyurethane material with good cushioning effect, and in terms of sole structure, they design air cushions, shock-absorbing columns, and other structures. However, regarding improvements to sole materials, different parts of the sole require different cushioning performance, and soles made of the same material cannot meet these needs. As for improvements to sole structure, there are problems such as an overall stiff structure and low comfort. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned defects or problems in the prior art and to provide a shock-absorbing and supportive sole and shoe, which has the advantages of good shock-absorbing and supportive performance and high wearing comfort.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Technical Solution 1: A cushioning and support sole, comprising: a midsole, which includes two support components; the two support components are respectively located on the inner and outer sides of the sole, and are spaced apart in a left-right direction to form a gap groove; the two opposite sides of the support components in the left-right direction are respectively a first side and a second side; the first side is provided with at least one first groove module arranged in a front-back direction; the first groove module includes two first grooves extending in the front-back direction; the first groove is provided with a connecting wall connecting the two groove walls in a diagonal direction, and the connecting wall is used to separate two notches; the second side is provided with at least one second groove module arranged in a front-back direction; the second groove module includes two grooves extending in the front-back direction and corresponding one-to-one with each of the first grooves. The first groove module has a first staggered portion formed between the ends of two adjacent first grooves; the second groove module has a second staggered portion formed between the ends of two adjacent second grooves; the first staggered portion is recessed towards the second side along the first direction to form a staggered valley, and the second staggered portion forms a staggered ridge that protrudes from the bottom of each second groove along the second direction corresponding to the position of the staggered valley; an upper bottom is fixed above the middle bottom to connect the two support members; a connecting layer is fixed below the middle bottom to connect the two support members, and is elastic in the left and right direction to allow the bottom opening of the spacer groove to open; and a large bottom is fixed below the connecting layer corresponding to the two support members.

[0006] Technical Solution 2 based on Technical Solution 1: The width of the interval groove in the left-right direction first increases and then decreases from front to back, and the maximum value of its groove width is formed in the arch area of ​​the sole.

[0007] Technical Solution 3 based on Technical Solution 1: The spacer groove extends smoothly in a streamlined shape on the projection plane perpendicular to the vertical direction. The part corresponding to the forefoot area of ​​the sole is curved outward, and the part corresponding to the heel area of ​​the sole is curved inward. The part corresponding to the arch area of ​​the sole smoothly connects the part corresponding to the forefoot area and the part corresponding to the heel area.

[0008] Technical Solution 4 based on Technical Solution 1: The first groove module and the second groove module are provided at least corresponding to the forefoot, arch and heel of the shoe sole, and the groove width of the first groove and the second groove located at the forefoot position is smaller than the groove width of the first groove and the second groove located at the arch position and / or the heel position.

[0009] Technical solution five based on technical solution one: The first slot module further includes at least one third slot extending in the vertical direction, wherein one of the third slots extends downward from the first intersecting portion to the bottom surface of the support component; the second slot module further includes at least one fourth slot extending in the vertical direction, wherein one of the fourth slots extends downward from the second intersecting portion to the bottom surface of the support component.

[0010] Technical solution six based on technical solution five: The connecting layer and the bottom are provided with notches corresponding to the third groove extending to the bottom surface of the support component.

[0011] Technical solution seven based on technical solution one: The top of the connecting wall set in the first groove forms a connecting ridge, and the two ends of the connecting ridge are connected to the two side walls of the first groove in a diagonal manner; the connecting wall extends upward from the bottom of the first groove, and its bottom is quadrilateral in shape on the projection plane perpendicular to the left and right direction, and the four vertices of the quadrilateral coincide with the two side walls of the first groove respectively.

[0012] Technical solution eight based on technical solution one: Each side wall of the second groove includes a first wall surface and a second wall surface; both first wall surfaces are formed by extending from the top edge of the second groove to the bottom of the groove; the second wall surface intersects with the first wall surface in the same side groove wall and with the bottom of the second groove to form a first intersection line and a second intersection line; the second intersection lines corresponding to the two second wall surfaces in the second groove coincide.

[0013] Technical solution nine based on technical solution eight: the wall surface of the notch in the first groove facing the groove wall of the first groove is a third wall surface, and the third wall surface is approximately parallel to the second wall surface in the groove wall on the side corresponding to the notch position in the second groove.

[0014] In addition, the present invention also provides technical solution ten: a shoe, which includes an upper and a cushioning support sole based on any one of technical solutions one to nine, wherein the upper is attached to the sole.

[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects: Technical solution one provides a cushioning support sole. The sole has support components on the inner and outer sides of the midsole. The connecting wall in the first groove is designed as a thin-walled structure that is prone to geometric deformation in a specific direction. The notches on both sides provide the necessary deformation space. Therefore, when subjected to initial impact force, the energy is mainly dissipated by driving the connecting wall to undergo preset controllable buckling deformation, rather than by material compression. This makes the component exhibit low stiffness in the early stage of compression, providing the user with a soft initial cushioning stroke. As the external pressure increases, the deformation of the connecting wall reaches its limit or contacts the adjacent structure. Its resistance to deformation increases nonlinearly, entering a high-support mechanical plateau period, preventing failure due to excessive compression. Secondly, the corresponding arrangement of the intersecting valleys of the first intersecting section and the intersecting ridges of the second intersecting section forms a matching concave and convex structure when the component is under pressure. This guides the entire groove module unit to contract and fold inward along a stable and defined path, ensuring that the local buckling behavior dominated by the connecting wall occurs in a controllable state. This avoids the possibility of disordered collapse or lateral shear failure of the structure, allowing the impact energy to be stably absorbed and converted. In addition, by dividing the midsole into two support components, the medial and lateral sides, and forming a spacer groove, the two sides of the sole can respond to the force of the foot relatively independently. When the foot pronates or supinates, the component on the corresponding side first undergoes compressive deformation to dissipate energy. The elastic connecting layer allows the bottom of the spacer groove to open, providing the component with additional lateral deformation space and flexibility. This effectively resists lateral forces and prevents excessive deflection of the sole, reducing the overall weight of the sole while ensuring support performance and balancing the flexibility and stability of the sole.

[0016] In technical solution two, the groove width in the left-right direction adopts a non-uniform design that increases from front to back and then decreases. The groove width reaches its maximum value in the arch area, effectively reducing the volume of solid material in the mid-section of the sole. While reducing the overall weight of the sole, it provides ample deformation and cushioning space for the plantar fascia to stretch and contract during exercise and for the natural settlement of the arch, avoiding discomfort caused by excessive pressure on the arch due to an overly hard midsole. At the same time, it moderately reduces the torsional stiffness of the midfoot, allowing the front and rear ends of the foot to generate necessary relative torsion under complex road conditions. In the forefoot and heel areas, the smaller groove width ensures that these two key contact and push-off areas have a more continuous and compact support structure. This ensures that the support components on the inner and outer sides of the foot can maintain good structural integrity and stability when bearing high impact loads and providing propulsion force, preventing power transmission loss or unstable swaying caused by excessive gaps.

[0017] In technical solution three, the spacer groove extends smoothly in a streamlined shape on the projection plane perpendicular to the vertical direction. The spacer groove protrudes outward in the forefoot area and inward in the heel area, and smoothly connects through the arch area. This conforms to the movement trajectory of the human body during walking or running, where the center of pressure on the sole of the foot lands on the outside of the heel and gradually transitions to the inside of the forefoot. The support components on the inside and outside of the foot can adapt to the natural rotation and weight transfer of the foot during the gait cycle, guiding the user's center of gravity to smoothly transition along the preset optimal path, thereby significantly improving the smoothness and coordination during movement.

[0018] In technical solution four, the groove width affects the stiffness and deformation capacity of the groove. A smaller groove width results in lower stiffness and easier deformation, providing better flexibility and initial cushioning; a larger groove width results in higher stiffness and stronger support. The forefoot is the primary area of ​​force and flexion during movement, requiring high flexibility. A smaller groove width allows for easier deformation of components in the forefoot to adapt to foot flexion movements while providing initial cushioning. The arch is the support area of ​​the foot, requiring strong support to maintain foot shape. A larger groove width increases the stiffness of components in the arch area to reduce arch pressure. The heel is the first part to strike the ground and bears the greatest impact; a larger groove width gives the components in the heel higher stiffness to resist greater impact forces. This zoned groove width design allows the cushioning support components to achieve differentiated mechanical properties along the length of the sole, meeting the different biomechanical needs of the forefoot, arch, and heel.

[0019] In technical solution five, the third and fourth grooves, which extend vertically to the bottom surface of the support component, are respectively provided in the first and second groove modules. The third and fourth grooves further improve the deformation capacity of the first and second groove modules under pressure, and can provide a larger cushioning rebound stroke, thereby further improving the overall cushioning and support performance of the sole.

[0020] In technical solution six, the connecting layer and the outsole are provided with notches corresponding to the third groove extending to the bottom surface of the support component. This avoids the connecting layer and the outsole from restricting the deformation of the third groove, ensuring that the third and fourth grooves can open or close freely when the sole undergoes severe bending deformation, thereby ensuring the normal realization of the shock absorption and support performance of the support component.

[0021] In technical solution seven, the connecting ridge formed at the top of the connecting wall in the first groove and its two ends connected diagonally to the groove wall provide a reinforced force transmission path when the connecting wall buckles under pressure. This allows the pressure on the connecting wall to be quickly transferred to the groove wall of the first groove, promoting uniform deformation of the connecting wall and preventing damage due to excessive local stress. At the same time, the presence of the connecting ridge significantly enhances the structural stability of the connecting wall and improves the durability of the component. Furthermore, the design of the bottom projection of the connecting wall being quadrilateral with its four vertices coinciding with the two side groove walls results in a larger and more regular contact area between the bottom of the connecting wall and the groove wall, achieving balanced force transmission and avoiding stress concentration at the connection point. This reduces the risk of damage to the connection part. Moreover, the quadrilateral shape, as a stable geometric shape, restricts the horizontal displacement and torsional deformation of the connecting wall under stress, ensuring the positional consistency and support stability of the connecting wall within the first groove.

[0022] In technical solution eight, the wall of the second groove is composed of a first wall surface and a second wall surface forming a folded structure. The second intersection lines corresponding to the two second wall surfaces coincide, causing the two second wall surfaces to converge on the same straight line at the bottom of the groove, forming a convergent force-bearing structure. When the component is under pressure, the force borne by the two second wall surfaces can be transmitted along their respective wall surfaces to the coinciding second intersection line, and then from this line to other parts of the bottom of the groove. This concentrated transmission method not only avoids the efficiency reduction caused by the dispersion of force at the bottom of the groove, but more importantly, it ensures that the deformation of the two second wall surfaces is coordinated with each other, that is, both deform synchronously around the same central intersection line. This effectively prevents the instability of the groove wall structure caused by deformation on one side being too fast or too slow, thereby simplifying the internal force system of the second groove and enhancing the overall stability of the structure.

[0023] In technical solution nine, the third wall of the missing groove in the first groove is roughly parallel to the corresponding second wall in the second groove. When the sole is compressed, the force on the third wall is transmitted along its extension direction, which is consistent with the force direction on the second wall. This allows both to bear the component force in the same direction simultaneously, avoiding internal structural conflicts caused by differences in wall direction. The first and second grooves can maintain the same deformation trend when deforming, improving the support capacity in a specific direction, and also making the energy transfer between the first and second grooves smoother.

[0024] Technical solution ten provides a shoe comprising an upper and a sole as described in any of the preceding claims, wherein the upper is attached to the sole. The sole provides cushioning and support, and after the upper is attached, it transmits the cushioning effect of the sole to the foot. Simultaneously, the upper wraps around the foot and works in conjunction with the sole to fix the foot's position, preventing the foot from sliding inside the shoe during exercise and improving wearing stability.

[0032] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0033] Example This invention relates to a shoe, the structure of which is as follows: Figures 10 to 12 It includes, for example Figure 1 The image shows the sole and the upper attached to it. The upper is attached to the sole using conventional shoemaking processes such as bonding, stitching, hot pressing, or one-piece molding to form a complete shoe. The upper is typically made of fabric, leather, synthetic materials, or a combination thereof, and is used to wrap the user's foot. When the upper is attached to the sole, the two work together. The upper is responsible for fixing the foot's position, preventing relative slippage within the shoe during movement, and effectively transferring foot pressure to the sole. The sole provides excellent cushioning, rebound, and dynamic support, thereby improving the wearer's athletic performance and comfort.

[0034] Among them, reference Figure 1 The sole includes a midsole, an upper 600, a connecting layer 710, and an outsole 720. Before describing the structure of the sole, it is necessary to first explain the directional definitions in the specification and claims of this invention. Since the sole is used in a shoe, it corresponds to the outer and inner sides of the human foot and can be defined in a left-right direction. For example, for the left foot, the left side is the outer side and the right side is the inner side. In addition, the sole also defines a front-back direction and a vertical direction. The front-back direction is the length direction of the sole, and the vertical direction is the thickness direction of the sole.

[0035] First, the structure of the shoe sole will be explained in detail.

[0036] The midsole of the shoe sole includes two support components 100, which are located on the inner and outer sides of the sole, respectively, and are spaced apart in the left-right direction to form a gap groove 800; the upper sole 600 is fixed above the midsole to connect the two support components 100; the connecting layer 710 is fixed below the midsole to connect the two support components 100, and is elastic in the left-right direction to allow the bottom opening of the gap groove 800 to open; the outsole 720 is fixed below the connecting layer 710 corresponding to the two support components 100.

[0037] Specifically, first refer to Figure 1The midsole of the shoe sole includes two structurally similar support components 100, the specific structure of which is detailed below. These two support components 100 are independent components and can be made of conventional foam materials, such as ethylene-vinyl acetate copolymer (EVA), thermoplastic polyurethane (TPU), expanded thermoplastic polyurethane (E-TPU), or nylon elastomer (PEBA), which are elastic materials with good cushioning and rebound properties. The two support components 100 are respectively located on the inner and outer sides of the sole. Because they are independent and maintain a distance in the left-right direction, a spacer groove 800 extending in the front-back direction is formed between the two support components 100.

[0038] Reference Figure 1 and Figure 4 A top sole 600 is disposed above the two support components 100. The top sole 600 is typically a sheet-like structure, spanning a spacer groove 800. Its bottom surface is fixedly connected to the top surfaces of the two support components 100 located on the inner and outer sides of the foot through methods such as bonding or heat pressing. The presence of the top sole 600 connects the two originally independent support components 100 into a single unit at the top, not only limiting excessive separation of the support components 100 during movement and ensuring the stability of the sole structure, but also providing a load-bearing platform for the foot (or for attaching to the upper), enabling the even transmission of pressure applied by the body to the support components 100 below. The material of the top sole 600 can be the same as or similar to that of the midsole to make the connection between the top sole 600 and the midsole more secure.

[0039] Reference Figure 1 and Figure 5Below the two support components 100, a connecting layer 710 and an outsole 720 are provided. The connecting layer 710 can be fixed to the lower surface of the support component 100 first, and the outsole 720 can then be fixed to the lower surface of the connecting layer 710. The connecting layer 710 spans across the two support components 100, thereby sealing the bottom of the spacer groove 800. The connecting layer 710 is made of a material that is elastic in the left-right direction (such as elastic rubber, thermoplastic polyurethane elastomer, or elastic fabric). Its fixed position under the midsole not only maintains the integrity of the inner and outer foot support components 100, but more importantly, when the two support components 100 are compressed and undergo lateral displacement, the connecting layer 710 can undergo tensile deformation, allowing the bottom opening of the spacer groove 800 to open accordingly, thereby giving the sole the ability to dynamically adapt to the ground. The outsole 720 is typically made of abrasion-resistant rubber material, and its shape corresponds to the bottom contour of the two support components 100. This provides grip and abrasion protection for the sole while avoiding interference with the elastic deformation of the connecting layer 710 in the spacer groove 800 area. The connecting layer 710 has several through holes 711 in the area corresponding to the spacer groove 800. These through holes 711 reduce the pulling force of the connecting layer 710 on the two support components 100, allowing for better deformation of the two support components 100. They also provide ventilation channels, preventing the spacer groove 800 from being closed and forming a sealed chamber.

[0040] Reference Figure 2 and Figure 3 The width of the spacer groove 800 in the left-right direction increases first and then decreases from front to back, with its maximum width formed in the arch area of ​​the sole. Furthermore, the spacer groove 800 extends smoothly in a streamlined shape on a projection plane perpendicular to the vertical direction. The portion corresponding to the forefoot area of ​​the sole curves outwards, while the portion corresponding to the heel area curves inwards. The portion corresponding to the arch area smoothly connects the portions corresponding to the forefoot and heel areas.

[0041] First, it's necessary to explain the division of the sole's areas. (Refer to...) Figure 2 The sole of the shoe is defined from front to back along the longitudinal direction (i.e., the length direction) as follows: forefoot portion 901, arch portion 902, and heel portion 903. The forefoot portion 901 is located at the front of the sole, corresponding to the forefoot and toes of the human foot, and is the main area for pushing off and bending during movement. The arch portion 902 is located in the middle of the sole, connecting the forefoot and heel, corresponding to the arch of the human foot. The heel portion 903 is located at the rear of the sole, corresponding to the heel of the human foot, and is typically the primary impact area when striking the ground. It should be understood that the above division is only a general division based on the structure of the human foot, and those skilled in the art will understand that this division does not have clear or definite dividing lines on the sole.

[0042] In this embodiment, the two opposing sides of the support member 100 along the left-right direction are designated as the first side 101 and the second side 102. In this embodiment, the first side 101 of the support member 100 located on the outer foot side faces the outer foot side, and the second side 102 faces the inner foot side; conversely, the first side 101 of the support member 100 located on the inner foot side faces the inner foot side, and the second side 102 faces the outer foot side. The shape of the gap groove 800 is determined by the shapes of the second sides 102 of the two support members 100. The gap groove 800, projected onto a plane perpendicular to the vertical direction, presents an S-shaped or wavy streamlined structure extending approximately in the front-back direction. The gap groove 800 protrudes outwards towards the outer foot in the forefoot area and inwards towards the inner foot in the heel area. This conforms to the natural internal rotation and weight transfer of the foot during the gait cycle, guiding the user's center of gravity along a predetermined, smooth path from the heel to the forefoot, avoiding discomfort caused by structural obstruction during movement, and effectively improving the smoothness and stability of the stride.

[0043] The structure of the midsole support component 100 will now be described in further detail.

[0044] Reference Figure 1 and Figure 6 The supporting component 100 has two opposing sides in the left-right direction, namely a first side 101 and a second side 102. The first side 101 has at least one first groove module 200 arranged in the front-back direction. Each first groove module 200 includes two first grooves 210 extending in the front-back direction. A connecting wall 220 connecting the two groove walls diagonally is provided within each first groove 210, and the connecting wall 220 divides the grooves into two notches 221. The second side 102 has at least one second groove module 300 arranged in the front-back direction. The second groove module 300 includes two... A second groove 310 extends along the front-back direction and corresponds one-to-one with each of the first grooves 210; a first interlacing portion 400 is formed between the ends of two adjacent first grooves 210 in the first groove module 200; a second interlacing portion 500 is formed between the ends of two adjacent second grooves 310 in the second groove module 300; the first interlacing portion 400 is recessed towards the second side 102 along the first direction to form an interlacing valley 410, and the second interlacing portion 500 forms an interlacing ridge 510 that protrudes from the bottom of each second groove 310 along the second direction corresponding to the position of the interlacing valley 410.

[0045] The first slot module 200 further includes at least one third slot 230 extending in the vertical direction, wherein the third slot 230 extends downward from the first intersecting portion 400 to the bottom surface of the support member 100; the second slot module 300 further includes at least one fourth slot 320 extending in the vertical direction, wherein the fourth slot 320 extends downward from the second intersecting portion 500 to the bottom surface of the support member 100.

[0046] Furthermore, the top of the connecting wall 220 in the first groove 210 forms a connecting ridge 222, and the two ends of the connecting ridge 222 are diagonally connected to the two side walls of the first groove 210. The connecting wall 220 extends upward from the bottom of the first groove 210, and its bottom is quadrilateral in shape on the projection plane perpendicular to the left and right directions. The four vertices of the quadrilateral coincide with the two side walls of the first groove 210. Also, each side wall of the second groove 310 includes a first wall surface 311 and a second wall surface 312. Both first wall surfaces 311 extend from the top edge of the second groove 310 towards the bottom. The second wall surface 312 intersects with the first wall surface 311 on the same side wall and with the bottom of the second groove 310 to form a first intersection line 313 and a second intersection line 314. The second intersection lines 314 corresponding to the two second wall surfaces 312 in the second groove 310 coincide. Among them, the wall surface of a notch 221 in the first groove 210 facing the groove wall of the first groove 210 is the third wall surface 223, which is approximately parallel to the second wall surface 312 in the side groove wall of the second groove 310 corresponding to the position of the notch 221.

[0047] Specifically, refer to Figure 7 and Figure 8 The two images respectively illustrate the structure of the first side surface 101 and the second side surface 102 of the support component 100 in one embodiment. The first groove module 200 provided on the first side surface 101 includes two first grooves 210 and two third grooves 230, and the second groove module 300 provided on the second side surface 102 includes two second grooves 310 and two fourth grooves 320. In this embodiment, the first grooves 210 and third grooves 230 have similar structures, and the second grooves 310 and fourth grooves 320 have similar structures; therefore, in... Figure 7 and Figure 8 The structure marked in the third slot 230 or the fourth slot 320 also has the same structure in the first slot 210 and the second slot 310.

[0048] The support component 100 includes a body that extends in the front-to-back direction to form a strip, and has a first side 101 and a second side 102 that are opposite to each other in the left-to-right direction. In this embodiment, the cross-section of the body perpendicular to the front-to-back direction is approximately rectangular or an irregularly shaped structure designed according to the foot shape. It can be made of elastic materials such as thermoplastic polyurethane (TPU), nylon elastomer (PEBA), or ethylene-vinyl acetate copolymer (EVA) to provide the necessary shock absorption and rebound performance.

[0049] The first groove module 200 recessed on the first side 101 includes two first grooves 210 and two third grooves 230. The two first grooves 210 extend in the front-to-back direction, and the two third grooves 230 extend in the vertical direction. The extension direction of the two third grooves 230 is not completely vertical, but has a certain angle of inclination with the vertical direction. Thus, the two first grooves 210 and the two third grooves 230 form a structure arranged circumferentially around a groove axis. The groove axis extends in the left-to-right direction. In this embodiment, a connecting wall 220 is provided in both the first groove 210 and the third groove 230. The connecting wall 220 connects to the two side walls of the first groove 210 or the third groove 230 along the focusing direction. Here, "connecting along the focusing direction" means that relative to the extension direction defined by the two side walls of the first groove 210 or the third groove 230, the connecting wall 220 is substantially intersecting the extension direction. Due to this arrangement of the connecting wall 220, the connecting wall 220 cooperates with the corresponding groove wall in the direction perpendicular to the extension direction to form a recessed notch 221. One of the first grooves 210 or one of the third grooves 230 will have two notches 221 set at diagonal positions.

[0050] Reference Figure 7The top of the connecting wall 220 in the first groove 210 and the third groove 230 forms a connecting ridge 222, and the two ends of the connecting ridge 222 are diagonally connected to the two side walls of the first groove 210 or the third groove 230. Specifically, the connecting wall 220 is a tapered structure that is wider at the bottom and narrower at the top, and the connecting ridge 222 is a linear protrusion at the top of the connecting wall 220, the direction of which is consistent with the main body direction of the connecting wall 220. The two ends of the connecting ridge 222 are respectively fixed to the inner surfaces of the two side walls of the first groove 210 or the third groove 230. These two fixing points are diagonally distributed on the cross-section of the first groove 210. The two walls of the connecting wall 220 are also inclined and intersect the corresponding groove wall of the first groove 210 at an inclination, so that the connecting ridge 222 and the two side walls together form a stable triangular support frame. This frame can effectively transmit the tension or pressure between the groove walls and prevent the connecting wall 220 from twisting under stress. The connecting wall 220 extends to the top of the first groove 210 or the third groove 230, and the two ends of the connecting ridge 222 are connected to the top of the first groove 210 or the third groove 230. The connecting wall 220 extends upward from the bottom of the groove, and its top surface is on the same horizontal plane as the top surface of the first groove 210. The two ends of the connecting ridge 222 are not connected to any arbitrary position on the groove wall, but are precisely connected to the edge of the groove top, making the connecting ridge 222 part of the groove top structure. This design allows the load on the groove top area to be directly transferred to the connecting wall 220 through the connecting ridge 222 when under pressure, avoiding local indentation caused by the groove top being subjected to force alone. In this embodiment, the two ends of the connecting ridge 222 are connected to the two diagonally opposite ends of the groove end of the first groove 210. Specifically, the groove end of the first groove 210 or the third groove 230 refers to the two end boundaries of the first groove 210 or the third groove 230 in the extension direction. One end of the connecting ridge 222 connects to the upper front corner (or lower rear corner) of one groove end, and the other end connects to the lower rear corner (or upper front corner) of another groove end. These two ends form the body diagonal of the first groove 210 or the third groove 230 in three-dimensional space. The bottom of the connecting wall 220 is integrally formed with the bottom of the first groove 210 or the third groove 230, and its root is completely fixed to the bottom plane of the groove. The height of the connecting wall 220 can be adjusted according to design requirements, usually 70% to 100% of the depth of the first groove 210 or the third groove 230. When viewed from above and below, the bottom outline of the connecting wall 220 is a quadrilateral. The four sides of this quadrilateral connect to the inner surfaces of the two side walls and two end walls of the first groove 210 or the third groove 230, and the four corner points fall exactly on the intersection lines of the two side walls and the groove ends, thus achieving a complete fit between the bottom of the connecting wall 220 and the inner wall of the groove cavity. The four corner points of the quadrilateral at the bottom of the connecting wall 220 are directly connected to the four corner points of the two ends of the first groove 210 or the third groove 230 (i.e., the four intersection points of the groove ends and the two side groove walls).

[0051] In addition, refer to Figure 7 When the first groove 210 or the third groove 230 is arranged around the groove axis, two adjacent grooves in the first groove 210 or the third groove 230 will meet at their ends to form an angle, and these four angles include two acute angles and two obtuse angles. Specifically, the two adjacent grooves forming the acute angle region (one along the first direction and one along the third direction) are... Figure 7 As shown, in the acute-angled regions located at the upper front and lower rear corners, the connecting ridge 222 of each groove extends and is fixed to the solid material at the junction, with one end of the groove closest to the acute-angled region. In this way, the two connecting ridges 222 converge at the junction, jointly reinforcing this structurally weak area and preventing it from cracking under pressure. For the third groove 230, which extends obliquely in the vertical direction, the connecting ridge 222 inside is not arranged along the extension direction of the third groove 230, but rather along the vertical direction. This means that the connecting ridge 222 is a vertical reinforcing rib, whose main function is to resist lateral loads from the vertical direction and enhance the stability of the third groove 230 in the height direction.

[0052] It should be noted that, in one embodiment, the third groove 230 may be provided at the upper and lower parts respectively, or preferably at the lower part, and the third groove 230 is open at the groove end in the vertical direction so that the third groove 230 can be connected to the bottom surface of the support member 100.

[0053] A first staggered portion 400 is also provided in the first slot module 200, which is formed as an staggered valley 410. Specifically, the staggered valley 410 is a recessed groove, with its two ends fixed to the bottom of the two first slots 210 respectively. These two fixing points are not arbitrarily chosen, but are each located at a diagonal corner of the bottom of their respective slots. For example, one end connects to the lower rear corner of the bottom of the front first slot 210, and the other end connects to the upper front corner of the bottom of the rear first slot 210. The extension direction of the staggered valley 410 is similar to the extension direction of the connecting ridge 222 of the connecting wall 220 in the two first slots 210. Here, "same extension direction" means that, relative to the cross-section perpendicular to the front-rear direction, the extension direction of the staggered valley 410 and the extension direction of the connecting ridge 222 both slope towards the same side. For example... Figure 7 The extension direction of the intersecting valley 410 is from the lower front corner to the upper rear corner, and the extension direction of the connecting ridge 222 in the two first grooves 210 is also from the lower front corner to the upper rear corner of the first groove 210.

[0054] The first interlacing portion 400 extends from the interlacing valley 410 along the left-right direction toward the tops of the two first grooves 210, forming two opposing first interlacing sidewalls 420. The tops of the first interlacing sidewalls 420 connect to the two diagonally opposite ends of the tops of the two first grooves 210 and are located on both sides of the interlacing valley 410 in a projection plane perpendicular to the second direction. The first interlacing portion 400 is a U-shaped or V-shaped recessed structure formed by the interlacing valley 410 and the two sidewalls. The two first interlacing sidewalls 420 extend upward (along the second direction) from the two side edges of the interlacing valley 410, and their tops are respectively fixed to the diagonally opposite ends of the tops of the two first grooves 210. In the projection plane perpendicular to the left-right direction, these two sidewalls are located on the front and rear sides of the interlacing valley 410, forming a symmetrical support structure that guides and constrains the overall deformation of the first interlacing portion 400.

[0055] Reference Figure 8 A second groove module 300 is recessed on a second side 102 opposite to the first side 101. This second groove module 300 includes two second grooves 310 and two fourth grooves 320. The two second grooves 310 extend in the front-to-back direction, and the two fourth grooves 320 extend in the vertical direction. The extension direction of the two fourth grooves 320 is not completely vertical, but rather at a certain angle to the vertical direction. Thus, the two second grooves 310 and the two fourth grooves 320 form a structure arranged circumferentially around the groove axis, and their positions correspond one-to-one with the first groove 210 and the third groove 230 of the first side 101.

[0056] In this embodiment, the second groove 310 and the fourth groove 320 are constructed as inwardly recessed groove-shaped structures. Each side of the groove wall is not a single plane, but a folded structure composed of a first wall surface 311 and a second wall surface 312. Both first wall surfaces 311 are formed by extending from the top edge of the second groove 310 or the fourth groove 320 to the bottom of the groove, and the two together define the extension direction of the second groove 310 or the fourth groove 320. The second wall surface 312 intersects with the first wall surface 311 in the same side groove wall and with the bottom of the second groove 310 or the fourth groove 320 to form a first intersection line 313 and a second intersection line 314.

[0057] Reference Figure 8The ends of the first intersection line 313 in the second groove 310 and the fourth groove 320 are respectively connected to the top and bottom of the groove wall. Specifically, the first intersection line 313 is the turning line between the first wall surface 311 and the second wall surface 312, with its upper end located at the edge of the groove top and its lower end located on the bottom plane, running through the entire height of the groove wall. Furthermore, the ends of the first intersection line 313 are respectively connected to the two diagonally opposite ends of the groove top and bottom of the groove wall. For a single side of the groove wall of a second groove 310 or a fourth groove 320, the upper end of its first intersection line 313 is connected to a front upper corner (or rear lower corner) of the groove top, and the lower end is connected to the rear lower corner (or front upper corner) of the groove bottom. This diagonal connection makes the first intersection line 313 the body diagonal of the groove wall, which can most effectively guide the groove wall to buckle along the diagonal direction.

[0058] In the second groove 310 or the fourth groove 320, the second intersection lines 314 corresponding to the two second walls 312 coincide. This means that the second intersection lines 314 formed by the intersection of the second walls 312 on the left and right sides of the second groove 310 or the fourth groove 320 with the bottom of the groove are not two independent lines, but coincide as a single straight line located at the center of the bottom of the groove. This coincident second intersection line 314 is the central ridge line of the bottom of the groove, and the second walls 312 on both sides are inclined inward with this line as the axis, so that the bottom of the groove presents a V-shaped pointed bottom or a converging structure. The ends of the second intersection line 314 in the second groove 310 or the fourth groove 320 are respectively connected to the two diagonally opposite endpoints of the bottom of the groove. For example, for the second groove 310 extending in the front-back direction, one end of the coincident second intersection line 314 is connected to the upper front corner of the bottom of the groove, and the other end is connected to the lower rear corner, which geometrically echoes the inclined trend of the aforementioned first intersection line 313.

[0059] In addition, refer to Figure 8 When the second groove 310 or the fourth groove 320 is arranged around the groove axis, two adjacent grooves in the second groove 310 or the fourth groove 320 also intersect at the ends to form angles, including two acute angles and two obtuse angles. Specifically, in the two adjacent grooves forming the acute angle region (one along the first direction and one along the third direction), the first intersection line 313 of each groove extends close to one end of the acute angle region and connects to the edge of the solid material at this junction. In this way, the folded structure within the adjacent grooves forms a continuous stress transfer path at the junction, ensuring the coordination of deformation. For the fourth groove 320, which extends obliquely in the vertical direction, its internal first intersection line 313 extends in the vertical direction. This means that the fold line mainly serves as a vertical guide line, guiding the groove wall of the fourth groove 320 to fold inward in an orderly manner when subjected to vertical compression.

[0060] It should be noted that in one embodiment, the fourth groove 320 can also be provided at the upper and lower parts respectively, or preferably at the lower part. The fourth groove 320 is open at the groove end in the vertical direction so that the fourth groove 320 can be connected to the bottom surface of the support member 100, thereby cutting off the continuous solid below the second intersecting part 500 and releasing the deformation degree of freedom.

[0061] A second staggered portion 500 is also provided in the second slot module 300, which is formed as a staggered ridge 510. Specifically, the staggered ridge 510 is a raised ridge line, with its two ends fixed to the tops of the two second slots 310 respectively. These two fixing points are also diagonally opposite corners of their respective slot tops; for example, one end is at the upper front corner of the top of the rear second slot 310, and the other end is at the lower rear corner of the top of the front second slot 310, ensuring that the positioning of the staggered ridge 510 is consistent with the diagonal direction of the entire structure. The extension direction of the staggered ridge 510 is similar to the extension direction of the second intersection line 314 (the center line of the slot bottom) in the two second slots 310. Here, "same extension direction" means that, relative to the cross-section perpendicular to the front-rear direction, the extension direction of the staggered ridge 510 and the extension direction of the second intersection line 314 both incline towards the same side. For example... Figure 8 The extension direction of the intersecting ridge 510 is from the upper rear corner to the lower front corner, and the extension direction of the second intersection line 314 in the two second grooves 310 is also from the upper rear corner to the lower front corner of the second groove 310.

[0062] The second staggered portion 500 extends from the staggered ridge 510 toward the bottom of each of the second grooves 310, forming two opposing second staggered sidewalls 520. The bottom ends of the second staggered sidewalls 520 are connected to the two diagonally opposite endpoints of the bottom of the two second grooves 310 and are located on both sides of the staggered ridge 510 in a projection plane perpendicular to the left and right direction. The second staggered portion 500 is an inverted U-shaped or inverted V-shaped protrusion structure formed by the staggered ridge 510 and the two sidewalls. The two second staggered sidewalls 520 extend downward (along the left and right direction) from the two side edges of the staggered ridge 510, and their bottom ends are respectively fixed to the diagonally opposite endpoints of the bottom of the two second grooves 310. In the projection plane perpendicular to the left and right direction, these two sidewalls are located on the front and rear sides of the staggered ridge 510, forming symmetrical support, jointly resisting external loads and guiding the overall deformation of the second staggered portion 500.

[0063] In this embodiment, when the support component 100 is applied to the sole, the first groove module 200 and the second groove module 300 are positioned at least corresponding to the forefoot, arch, and heel of the sole. The width of the first groove 210 and the second groove 310 located at the forefoot position is smaller than the width of the first groove 210 and the second groove 310 located at the arch and / or heel positions. Specifically, the opening distance of the first groove 210 or the second groove 310 perpendicular to the extension direction is the groove width. The groove width determines the closing stroke of the groove module under pressure and the deformation degree of freedom of the internal connecting wall 220. For the forefoot portion 901, the groove width of the first groove 210 and the second groove 310 is set to a smaller value, for example, 2.0 mm to 4.0 mm. Since the forefoot is the main area for pushing off the ground during movement, a smaller groove width allows the groove walls of the support component 100 in this area to contact each other more quickly or reach a structural locking state when under pressure, thereby reducing ineffective deformation stroke and enabling the forefoot to quickly generate a solid supporting reaction force, improving propulsion efficiency during push-off. For the heel area 903 and the arch area 902, the widths of the first groove 210 and the second groove 310 are set to larger values, such as 5.0 mm to 8.0 mm. The heel is usually the primary impact area when the foot strikes the ground during exercise, and it bears the greatest instantaneous impact force. A larger groove width provides more physical space (i.e., a larger cushioning stroke) for the buckling deformation of the connecting wall 220 and the inward collapse of the groove wall, allowing the support component 100 to undergo deeper compressive deformation in this area, thereby maximizing the duration of impact force and absorbing impact energy, providing the user with a soft and comfortable cushioning experience. For the arch area, a larger groove width helps to appropriately reduce the torsional stiffness of the midsole, avoiding discomfort caused by an overly stiff arch structure, and allowing the arch to undergo natural physiological sinking and rebound during the load-bearing cycle.

[0064] Furthermore, referring to Figure 1 The connecting layer 710 and the outsole 720 are provided with notches 730 corresponding to the third groove 230 extending to the bottom surface of the support member 100. Specifically, the notches 730 are positioned to correspond one-to-one with and communicate with the bottom opening of the third groove 230. By correspondingly providing the notches 730, the binding of the connecting layer 710 and the outsole 720 on the deformation area of ​​the third groove 230 is eliminated, so that when the sole is bent under force, the solid parts on both sides of the third groove 230 can move closer to each other or separate without obstruction, thereby ensuring that the preset mechanical performance of the support member 100 is fully utilized, and also significantly improving the overall bending flexibility of the sole.

[0065] It should be noted that, for other embodiments, the structure of the first side 101 and the second side 102 in the support member 100 described above can be adjusted. For example, the width of the first groove 210 and the second groove 310 can be increased, and the width of the third groove 230 and the fourth groove 320 can be decreased. Alternatively, only the lower third groove 230 can be provided on the first side 101, or only the lower fourth groove 320 can be provided on the second side 102.

[0066] Reference Figures 10 to 12 This illustrates a simulation of a shoe sole employing the aforementioned cushioning components. Figures 10 to 12 As can be seen, after the heel section 903 of the sole contacts the ground, the cushioning support unit 100 in the heel area is the first to undergo compression and flexion deformation, beginning to absorb and dissipate the initial impact energy. At this time, the stress is mainly concentrated in the contact area. As the body's center of gravity shifts forward, the stress area gradually transitions from the heel to the middle of the foot, and more cushioning units are activated and participate in coordinated deformation, smoothly distributing the impact force over a wider range. When the entire foot is under pressure, the deformation of most cushioning units approaches their geometric limits, and the overall structural stiffness is significantly improved, forming a stable, highly supportive platform that effectively resists peak pressure. Thus, a dynamic mechanical performance transformation from initial flexible cushioning to later rigid support is achieved throughout the gait cycle.

[0067] Reference Figures 13 to 15 The figures provided in this manual show a pair of proportions. It is clear that in the sole without the aforementioned cushioning components, the material strain caused by impact (red area in the figure) is highly concentrated at a single point of force, shifting from the heel to the forefoot with the gait cycle. This strain concentration indicates that energy is not effectively dispersed, easily leading to excessive local material compression, thereby reducing cushioning durability and comfort. It may also result in insufficient stability due to the lack of structured support.

[0068] By comparing the two sets of simulation images, we can draw the following conclusions. Figures 13 to 15 The conventional shoe sole shown exhibits a single, passive material compression pattern, resulting in a contradiction between its two core performance aspects: cushioning and support. However... Figures 10 to 12 The shoe sole shown, which incorporates the cushioning component of this invention, achieves a dynamic and phased mechanical response through geometric design: at the moment of impact, it disperses stress through structural deformation to achieve cushioning; when support is needed, it can provide stable platform support through the resistance between structures, thereby resolving the contradiction between cushioning and support and significantly improving the overall performance of the shoe sole.

[0069] This invention relates to a cushioning support sole, in which support components 100 are respectively provided on the inner and outer sides of the midsole. The connecting wall 220 in the first groove 210 is designed as a thin-walled structure that is prone to geometric deformation in a specific direction. The notches 221 on both sides provide the necessary deformation space. Therefore, when subjected to initial impact force, the energy is mainly dissipated by driving the connecting wall 220 to undergo preset controllable buckling deformation, rather than by material compression. This makes the component exhibit low stiffness in the early stage of compression, providing the user with a soft initial cushioning stroke. As the external pressure increases, the deformation of the connecting wall 220 reaches its limit or contacts the adjacent structure. Its resistance to deformation increases nonlinearly, entering a high-support mechanical plateau period, preventing failure due to excessive compression. Secondly, the corresponding arrangement of the intersecting valleys 410 of the first intersecting portion 400 and the intersecting ridges 510 of the second intersecting portion 500 forms a matching concave and convex structure when the component is compressed. This guides the entire groove module unit to contract and fold inward along a stable and defined path, ensuring that the local buckling behavior dominated by the connecting wall 220 occurs in a controllable state, avoiding the possibility of disordered collapse or lateral shear failure of the structure, and allowing the impact energy to be stably absorbed and converted. In addition, by dividing the midsole into two support components 100 on the inner and outer sides and forming a spacer groove 800, the two sides of the sole can respond to the force of the foot relatively independently. When the foot pronates or supinates, the component on the corresponding side first undergoes compression deformation to dissipate energy. The elastic connecting layer 710 allows the bottom of the spacer groove 800 to open, providing the component with additional lateral deformation space and flexibility, thereby effectively resisting lateral forces and preventing excessive deflection of the sole. While ensuring support performance, it reduces the overall weight of the sole and balances the flexibility and stability of the sole.

Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
