Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In order to shorten the customization period of the personalized insole, so that the retail end store can perform insole customization service, the embodiment of the application provides an insole which can shorten the customization period of the personalized insole, as shown in fig. 1, the insole 10 comprises a supporting layer 101 adjacent to a sole, the supporting layer 101 is provided with a first arch part 1011 and a first heel part 1012, and the first arch part 1011 and the first heel part 1012 are connected; and the constituent material of the support layer 101 includes a thermoplastic shape memory material. The structure of the support layer 101 is shown from the side in fig. 2, and the first arch part 1011 of the support layer 101 is provided as an arc-shaped protrusion, which is ergonomic and in a movement pattern, and can be more fitted to the arch of the wearer, so that the wearer can get a more comfortable and stable arch support.

In one embodiment, support layer 101 is made up of a first arch member 1011 and a first heel member 1012, with first arch member 1011 and first heel member 1012 being integrally formed. It will be appreciated that the support layer 101 now includes only a first arch component 1011 and a first heel component 1012, as shown in fig. 1 and 2.

In another embodiment, the support layer 101 also has a ball component (not shown), and the ball component, the first arch component 1011 and the first heel component 1012 of the support layer 101 are integrally formed. It will be appreciated that the shape of support layer 101 is now a full plantar shape and, in order to allow insole 10 to more closely conform to the arch of the wearer's foot so that the wearer may receive a more comfortable and stable arch support, the thickness of first arch part 1011 and first heel part 1012 of support layer 101 is greater than the thickness of the forefoot portion of support layer 101 so that the forefoot and hindfoot regions of insole 10 have a height drop that meets ergonomic and motion pattern requirements.

Because the supporting layer 101 included in the insole 10 is made of the low-temperature thermoplastic shape memory material, the supporting layer 101 can be softened at a lower heating temperature, a wearer only needs to step on the insole 10 for shaping, the supporting layer 101 conforming to the shape of the arch of the wearer can be obtained after the insole 10 is cooled, and the personalized insole conforming to the support of the arch of the wearer can be quickly obtained. The shoe pad 10 is customized individually, so that the time for customizing the shoe pad is greatly shortened, and the shoe pad customizing service in retail terminal shops can be performed quickly.

And, based on the characteristic that the material of the support layer 101 can be shaped at a low temperature, when the insole obtained through the above customization process does not conform to the arch shape of the wearer, the insole can be heated and softened again to perform the above customization process (shaping process). Or when the part of the insole obtained through the customization process does not conform to the arch state of the wearer, the part of the insole can be heated and softened for reshaping. Or, the insole obtained through the customization process is in accordance with the arch state of the wearer when walking, but is not in accordance with the arch state of the wearer when performing other sports (for example, a scene with more knees such as basketball), at this time, the insole can be heated and softened again, when shaping, the wearer can adjust the foot to the arch state corresponding to a certain sports scene, for example, the wearer can keep bending when stepping on the insole (at this time, the arch state of the wearer's foot is different from the arch state during walking), and the insole which is in accordance with the arch state in the sports scene can be obtained after the insole is cooled, so that the insole which is suitable for a certain sports scene can be considered to be obtained. Based on the supporting layer 101 which can be molded at low temperature, the insole can be molded repeatedly for many times, and can be molded according to the arch support requirements of various sports scenes of a wearer, so that the matching degree and diversity of the usage scenes of the insole are improved on the basis of shortening the customizing time of the insole.

In one embodiment, the thermoplastic temperature range of the low temperature thermoplastic shape memory material used to make the support layer 101 is 40 ℃ to 60 ℃. That is, the support layer 101 can be softened at a temperature ranging from 40 ℃ to 60 ℃, and a wearer can shape the support layer 101 by applying force to the feet after the support layer 101 is softened. The thermoplastic temperature range of 40-60 c is a lower temperature and safer temperature range, and the time for heating the heating device for softening the supporting layer 101 to the temperature range is shorter, so that the insole customization process is shortened, and the waiting time of consumers is reduced. If the thermoplastic temperature range is too high, the foot is easily scalded and uncomfortable, therefore, the thermoplastic temperature range of 40-60 ℃ is a safe temperature range, and when the foot of the wearer is applied on the heated and softened support layer 101 for shaping, the foot is not scalded and uncomfortable.

In actual wearing, if the stiffness of the support layer 101 is too great (stiff in texture), discomfort to the wearer's foot may result, while at the same time, the risk of athletic injury to the wearer's foot may increase. If the stiffness of support layer 101 is too low (softer), support layer 101 may not provide a stable support to the wearer's foot and may not provide the wearer with the benefit of exerting force on the foot during movement, which may affect the movement. Therefore, the supporting layer 101 may have a relatively suitable stiffness, which can improve the comfort of the foot of the wearer and simultaneously give the foot of the wearer stable support, thereby reducing the risk of athletic injuries to the foot of the wearer. Thus, in one embodiment, the shore a hardness of the material of the support layer 101 is in the range of 90-100. When the hardness of the support layer 101 is in the range of 90-100, the support layer 101 may improve the comfort of the wearer's foot, give the wearer's foot stable support and reduce the risk of athletic injury to the wearer's foot. Preferably, the support layer 101 has a shore a hardness of 95.

In one embodiment, the low temperature thermoplastic shape memory material from which support layer 101 is made comprises at least one of polycaprolactone, thermoplastic polyurethane, and is distributed in at least one of first arch member 1011 and first heel member 1012. That is, the low temperature thermoplastic shape memory material described above can be synthesized from at least one of polycaprolactone, thermoplastic polyurethane, and then utilized to fabricate at least one of first arch member 1011 and first heel member 1012 in support layer 101. Of course, in addition to polycaprolactone and thermoplastic polyurethane, other materials can be added to the low temperature thermoplastic shape memory material to improve other properties of the support layer 101, such as adding a suitable amount of ethylene-octene copolymer to improve the elasticity of the support layer 101 to facilitate the exertion of force on the foot of the wearer. In addition, other substances can be added to the low-temperature thermoplastic shape memory material according to the actual requirements of the specific foot, which is not described herein. On the other hand, the polycaprolactone and the thermoplastic polyurethane for preparing the low-temperature thermoplastic shape memory material are also used for orthopedic external fixation, orthopedic braces and the like, so that the low-temperature thermoplastic shape memory material has the characteristics of safety and no toxicity while having good molding effect and shape memory function after being heated and softened at low temperature.

To further improve the fit of insole 10 to the foot of the wearer and reduce foot slip between the foot and insole 10 during athletic activities, in one embodiment, insole 10 further comprises a conforming layer 102, the conforming layer 102 having a forefoot component, a second arch component, and a second heel component, the second arch component being connected to the forefoot component and the second heel component, respectively, a first arch component 1011 of the support layer 101 being disposed at a location corresponding to the second arch component of the conforming layer 102, and a first heel component 1012 of the support layer 101 being disposed at a location corresponding to the second heel component of the conforming layer 102; and the composition material of the conforming layer 102 includes a pressure-sensitive shape memory material. Because the fit layer 102 made of the pressure-sensitive shape memory material is introduced into the insole 10, when a force is applied to the insole 10 by the foot of a wearer, the fit layer 102 in the insole 10 can be plastically deformed (sunken), so that the fit layer 102 can be more fit to the foot of the wearer, and better comfort is provided; on the other hand, the stress area of the foot of the wearer and the insole is enlarged due to the plastic deformation, the pressure distribution of the foot of the wearer to the insole is dispersed, and the comfort level of the foot is further improved.

In practical applications, the fitting layer 102 made of the pressure-sensitive shape memory material may have different compressive yield stress points, that is, under the same foot pressure, different positions of the fitting layer 102 may have different degrees of plastic deformation (sagging at different depths), so as to meet the fitting requirements of the foot and the insole under different individuals, different sports scenes and sports strength. For example, in a walking sports scene, the first metatarsophalangeal joint and the heel area of the foot exert more force, the arch part exerts less force, the first metatarsophalangeal joint and the heel area of the corresponding attaching layer 102 can generate larger plastic deformation (deeper sinking), and the arch area can generate smaller plastic deformation (shallower sinking), so that the larger plastic deformation of the first metatarsophalangeal joint and the heel area of the attaching layer 102 can improve the attaching performance of the insole and the foot during walking, reduce the foot sliding between the foot and the insole during walking and provide power for walking, and meanwhile, the smaller plastic deformation of the arch area of the attaching layer 102 also plays a part of arch support. When the laminating layer 102 is made of a pressure-sensitive shape memory material, the pressure-sensitive shape memory materials with different yield stresses may be arranged at different positions of the laminating layer 102, that is, the pressure-sensitive shape memory materials with different yield stresses may be spliced to form the laminating layer 102, or may be integrally formed when the laminating layer 102 is made, and meanwhile, different regions of the laminating layer 102 may have different yield stresses; for example, when the lamination layer 102 is integrally formed, by setting the structure of the pressure sensitive shape memory material to have different cell morphologies in different regions, different yield stresses can be given to different regions of the lamination layer 102 (when the cell morphology in the structure of the pressure sensitive shape memory material is dense and uniform in size, the yield stress is larger, and when the cell wall in the structure of the pressure sensitive shape memory material is thinner and the size distribution is wider, the yield stress is smaller). For example, when the attaching layer 102 is manufactured by integral molding, the pore walls in the pressure-sensitive shape memory material structures arranged at the positions corresponding to the first metatarsophalangeal joint and the heel region of the attaching layer 102 are thin, the size distribution is wide, and the pores in the pressure-sensitive shape memory material structures arranged at the positions corresponding to the arch region of the attaching layer 102 are compact and uniform in size, so that the yield stress of the first metatarsophalangeal joint and the heel region of the attaching layer 102 is small, the yield stress of the arch region of the attaching layer 102 is large, when the shoe is in a walking state, the first metatarsophalangeal joint and the heel region of the attaching layer 102 can be subjected to large plastic deformation (deep sinking), the arch region can be subjected to small plastic deformation (shallow sinking), and further, under a walking motion scene, the fitting performance between the insole and the foot during walking is improved, and the foot sliding between the foot and the insole during walking is reduced, provides power for walking and simultaneously provides a supporting effect for the arch of foot. It should be understood that, in the walking scenario, the first metatarsophalangeal joint and the heel region of the attaching layer 102 may undergo a large plastic deformation (deep sinking), and the arch region may undergo a small plastic deformation (shallow sinking) only as an example, and according to different wearers, sports scenarios and sports strengths, the corresponding insole may be selected according to the sports habits, characteristics, sports scenarios and strengths thereof so as to cause the corresponding plastic deformation (the plastic deformation according to the sports habits, characteristics, sports scenarios and strengths) of the insole, which is not limited herein.

By introducing the attaching layer 102 made of the pressure sensitive shape memory material and having different yield stress points into the insole 10, the attaching of the foot of the wearer to the insole 10 under different sports scenes and sports strength can be realized, meanwhile, the stress area of the foot of the wearer and the insole is enlarged due to the plastic deformation of the attaching layer 102, the pressure of the foot of the wearer to the insole is dispersed, the fatigue of a certain stress point of the foot when the wearer stands for a long time is relieved, the lever arm of a forefoot during walking and sports is increased, the rolling efficiency of metatarsophalangeal joints is increased, and power is provided for walking and sports.

In one embodiment, the pressure sensitive shape memory material of the adhesive layer 102 is a polyurethane foam. As can be seen from the foregoing, when the adhesive layer 102 is made of a pressure-sensitive shape memory material, the pressure-sensitive shape memory materials with different yield stresses may be disposed at different positions of the adhesive layer 102, that is, the pressure-sensitive shape memory materials with different yield stresses may be spliced to form the adhesive layer 102, or the adhesive layer 102 may be integrally formed, and different areas of the adhesive layer 102 may have different yield stresses. The polyurethane foam material is a porous material, and when the attachment layer 102 is manufactured, the polyurethane foam material with a smaller porosity is arranged in an area where the attachment layer 102 requires a larger yield stress, and the polyurethane foam material with a larger porosity is arranged in an area where the attachment layer 102 requires a smaller yield stress, so that the cell structure in the polyurethane foam material in the area where the attachment layer 102 requires a larger yield stress is more compact and uniform, the cell walls in the polyurethane foam material in the area where the attachment layer 102 requires a smaller yield stress are thinner, and the cell diameter distribution is wider, so that corresponding smaller plastic deformation (shallower sagging) and larger plastic deformation (deeper sagging) are realized.

In practical situations, if the yield stress of the fitting layer 102 is too large, the wearer hardly generates plastic deformation when the insole applies force to the foot, so that the insole cannot meet the action of fitting the foot and dispersing the pressure; if the yield stress of the conforming layer 102 is too low, the insole is easily plastically deformed by the wearer when the insole applies a force to the foot, which is not conducive to providing power for the wearer to move. Therefore, the fit layer 102 in the insole needs to have a relatively suitable yield stress. In one embodiment, the conforming layer 102 has a yield stress in the range of 80-250KPa, it is understood that different regions of the conforming layer 102 can have different yield stresses within the yield stress range, for example, the arch region of the conforming layer 102 has a yield stress of 150KPa and the heel region of the conforming layer 102 has a yield stress of 100 KPa.

When the pressure-sensitive shape memory material for manufacturing the attaching layer 102 is a polyurethane foam material, the density of the pressure-sensitive shape memory material may be in a range of 0.10 to 0.20g/cm³Controlling the density of the pressure sensitive shape memory material within the density range may improve the comfort of the wearer's foot.

Likewise, if the conforming layer 102 is too stiff (stiff in texture) during wear, it may cause discomfort to the wearer's foot, and may also increase the risk of athletic injury to the wearer's foot. If the stiffness of conforming layer 102 is too low (softer texture), conforming layer 102 may not provide support to the arch of the wearer's foot and may not provide adequate control of foot force and stability during movement of the wearer, which may affect the movement. Therefore, the conforming layer 102 can have a suitable hardness, and in one embodiment, the pressure-sensitive shape memory material of the conforming layer 102 has a shore C hardness of 30-40. When the shore C hardness of the pressure-sensitive shape memory material of the fitting layer 102 is 30-40, the fitting layer 102 can improve the comfort of the foot of the wearer, provide arch support for the wearer, provide motion power, and reduce the risk of motion damage to the foot of the wearer.

In order to further improve the comfort of the insole and reduce the athletic injuries of the wearer during the use of the insole, the insole 10 further comprises an elastic layer 103, wherein the elastic layer 103 is arranged between the supporting layer 101 and the fitting layer 102, and the shape of the elastic layer 103 is matched with that of the fitting layer 102. The elastic layer 103 is introduced into the insole 10, which can provide enough resilience for a wearer during exercise, improve the support and stability of the insole during exercise, reduce sports injury and fatigue during exercise, and improve foot feeling and wearing comfort.

In one embodiment, the constituent material of the elastic layer 103 includes at least one of the following materials: polyurethane, ethylene-octene copolymer, ethylene-octene block copolymer, ethylene-vinyl acetate copolymer, styrene-butadiene block copolymer, hydrogenated styrene-butadiene block copolymer, nylon elastomer, polyester elastomer, brominated butyl rubber, butadiene rubber, silicone rubber, ethylene propylene diene monomer, wherein the polyurethane comprises cast polyurethane and/or thermoplastic polyurethane. Preferably, the composition material of the elastic layer 103 includes at least one of the following materials: polyurethane, ethylene-octene copolymer, ethylene-octene block copolymer, ethylene-vinyl acetate copolymer, hydrogenated styrene-butadiene block copolymer, nylon elastomer, polyester elastomer, wherein the polyurethane comprises cast polyurethane and/or thermoplastic polyurethane.

In one embodiment, the elastic layer 103 is made of a blend of ethylene-octene copolymer, ethylene-octene block copolymer, ethylene-vinyl acetate copolymer, hydrogenated styrene-butadiene block copolymer, and has a density of 0.10 to 0.18g/cm³The Shore C hardness is 30-40, and the impact resilience is 55-60%. Blends of ethylene-octene copolymers, ethylene-octene block copolymers, ethylene-vinyl acetate copolymers, hydrogenated styrene-butadiene block copolymersThe elastic layer 103 made, having the density ranges, the hardness ranges, and the resilience ranges, can provide sufficient resilience for the foot of the wearer, improve the support and stability of the insole during motion, reduce athletic injuries and fatigue during motion, and improve foot feel and wearer comfort.

To reduce impact forces from the ground during the landing phase of the athletic routine, first heel member 1012 of support layer 101 has an opening 1013; insole 10 further comprises shock absorbing mass 104, said shock absorbing mass 104 being inserted into opening 1013 and interfacing with first heel member 1012 of support layer 101. By introducing the shock-absorbing block 104 at the bottom of the insole 10, shock-absorbing effect can be provided when a wearer falls on the ground during movement, impact force of the ground to the wearer's foot and knee can be reduced, and movement injury can be reduced.

In one embodiment, the material from which the cushion block 104 is made comprises a foamed material comprising at least one of the following: polyurethane, ethylene-vinyl acetate copolymer, styrene-butadiene block copolymer, hydrogenated styrene-butadiene block copolymer, nylon elastomer, polyester elastomer, brominated butyl rubber, butadiene rubber, silicone rubber. Preferably, the foamed material comprises at least one of the following materials: polyurethane, ethylene-vinyl acetate copolymer, hydrogenated styrene-butadiene block copolymer, nylon elastomer, polyester elastomer, silicone rubber, wherein the polyurethane comprises cast polyurethane and/or thermoplastic polyurethane. More preferably, the foamed material comprises at least one of the following materials: polyurethane, ethylene-vinyl acetate copolymer, hydrogenated styrene-butadiene block copolymer, nylon elastomer, polyester elastomer, silicone rubber, wherein the polyurethane comprises cast polyurethane and/or thermoplastic polyurethane.

In one embodiment, the damper block 104 is made of polyurethane and has a density of 0.15 to 0.22g/cm³The Shore C hardness is 30-40, and the Peak acceleration (Peak G) is 8-10. The damper mass 104 made of polyurethane having the density range, the hardness range, and the peak acceleration range may be reduced in the falling stage of the motion processThe impact force from the ground is reduced, the impact force of the ground to the feet, ankles and knees of a wearer in the exercise process is reduced, and further the exercise injury is reduced.

In order to provide the bacteriostatic and deodorant effects, the insole 10 further comprises a surface layer 105, wherein the surface layer 105 is arranged on the surface of the attaching layer 102, and the shape of the surface layer 105 is matched with that of the attaching layer 102. The constituent material of the surface layer 105 includes at least one of the following materials: the surface layer 105 is made of polyamide fiber, spandex, terylene, polypropylene fiber, vinylon, acrylic fiber, polyvinyl chloride fiber, spandex, chitin fiber, coconut fiber, hemp and cotton, or at least one of the materials is used as a matrix, and phase change substances are added to prepare the phase change fiber with the functions of heat storage, temperature reduction and heat release regulation, and the phase change fiber is used as a component material of the surface layer 105. In one embodiment, the surface layer 105 is made of coconut fiber and terylene by blending in a ratio of 1:1, so that a good bacteriostatic, deodorant and breathable effect can be achieved.

The insole 10 having the support layer 101, the adhesive layer 102, the elastic layer 103, the shock absorbing block 104 and the surface layer 105 is shown in fig. 1, 2, 3, 4 and 5. Fig. 1 shows the stacking sequence of the support layer 101, the adhesive layer 102, the elastic layer 103, the shock-absorbing block 104 and the surface layer 105 in the insole 10. Fig. 2 is a side view of insole 10 having a support layer 101, a conforming layer 102, an elastic layer 103, a shock absorbing block 104, and a surface layer 105. Because the conventional insole is of a flat layer structure, the left side and the right side are not blocked, when a wearer moves or decelerates rapidly, the insole and the sole can move, and the foot, the ankle and the knee of the wearer are damaged. Accordingly, each layer of insole 10 of the present application has lateral edges 106, as shown in FIG. 5 (FIG. 5 is a cross-sectional view of insole 10 taken along section line A-A' of FIG. 4), which increase the contact friction area between the insole and the shoe while wrapping around the foot of the wearer, thereby preventing the insole and the sole from shifting and better distributing the pressure during the exercise. The arch and heel areas of conforming layer 102 and surface layer 105 are not visible in the schematic side view of insole 10 of fig. 2 due to the presence of side edge 106, it being understood that both conforming layer 102 and surface layer 105 have an arch and heel area. While fig. 3 also shows a top view of insole 10 having support layer 101, conforming layer 102, elastic layer 103, shock absorbing mass 104 and surface layer 105, fig. 4 shows a bottom view of insole 10 having support layer 101, conforming layer 102, elastic layer 103, shock absorbing mass 104 and surface layer 105.

Based on the insole provided by the application, the application also provides an insole customizing method:

putting the insole provided by the application into a heating device for heating;

placing the heated insole in a model conforming to the shape of the wearer's foot sole;

and the foot of the wearer steps on the heated insole to shape the insole to obtain the customized insole which conforms to the foot of the wearer.

With different scenes of standing, walking and running, the arch form of the foot is not completely the same, and when the insole is not matched with the arch form, power cannot be provided for sports, sports injury may be caused, and meanwhile, discomfort is caused. Therefore, insoles corresponding to the shapes of the arches of the feet are needed to be customized for different individuals or different sports scenes. In general, during customization, the arch form of the wearer needs to be evaluated to obtain arch data of the wearer, and the evaluation of the arch form requires the wearer to perform walking or running on a pressure plate of more than 6 meters. The customization method is long in time, and used equipment is not suitable for terminal retail stores with limited areas.

According to the personalized insole customizing method of the insole, the insole can be softened only by placing the insole in a heating device and heating to 40-60 ℃ for about one minute. The insole is heated, and a wearer can step on the device for forming the sole model by feet to obtain the sole model of the wearer, the device for forming the sole model can be an air bag, and the surface pressure and the shape of the air bag are changed by applying force to the foot of the wearer to establish a model which is matched with the shape of the sole. And (3) putting the heated insole into the built sole model, enabling the wearer to step on the insole, keeping the insole for a certain time (20-30 seconds), enabling the wearer to leave the insole, cooling and shaping the insole for 1-2 minutes, and correcting redundant corners to obtain the customized insole which is in accordance with the arch state of the wearer. Certainly, in the shaping process, a wearer can select different knee bending angles (for example, 80-100 degrees) and standing postures according to different sports requirements, and adjust the stress distribution of different areas of the foot to match with a better arch support radian and fit with the cup, so that the customized insole capable of supporting arches in different states under different sports scenes is obtained.

Because the supporting layer that the shoe-pad that this application provided included is made by thermoplastic shape memory material, under lower heating temperature, the supporting layer just can soften, and the person of dress only need the foot step on the shaping is carried out on the shoe-pad, treat can obtain the supporting layer that accords with the person's of dress arch shape after the shoe-pad cools off, can obtain the individualized shoe-pad that accords with the person's of dress arch support fast. The shoe pad is customized in a personalized manner based on the shoe pad, so that the customization time of the personalized shoe pad is greatly shortened, and the shoe pad customization service in retail terminal shops can be performed quickly.

And based on the characteristic that the material of the supporting layer can be shaped at low temperature, when the insole obtained through the customization process does not conform to the arch state of the wearer, the insole can be heated and softened to perform the customization process (shaping process). Or, when the part of the insole obtained through the customization process does not conform to the arch state of the wearer, the part of the insole can be heated and softened for reshaping. Or, the insole obtained through the customization process is in accordance with the arch state of the wearer when walking, but is not in accordance with the arch state of the wearer when performing other sports (for example, a scene with more knees bent such as basketball), the insole can be heated and softened again at this time, the wearer can adjust the foot to the arch state corresponding to a certain sports scene when shaping, for example, knees are bent (at this time, the arch state of the foot of the wearer is different from the arch state when walking), and the insole which is in accordance with the arch state in the sports scene can be obtained after the insole is cooled, so that the insole which is suitable for a certain sports scene can be considered to be obtained. Based on the supporting layer capable of shaping at low temperature, the insole can be repeatedly shaped for many times, shaping can be carried out according to the arch support requirements of various sports scenes of a wearer, and the diversity of the usage scenes of the insole is improved on the basis of shortening the customizing time of the insole.
