Description

Personalized insoles capable of rapid prototyping

This creation is about the structure of the insole, especially a personalized insole that can be quickly shaped according to the three-dimensional configuration of the sole of the individual's feet and is equipped with a negative pressure auxiliary element.

Press, when people wear shoes, insoles will be placed in the shoes to reduce the sole pain and other diseases caused by standing or walking for a long time by using the shock absorption and cushioning effect of the insoles, and at the same time, it can give the feet better comfort. feel. Generally speaking, under normal circumstances, the sole of the foot should have a significantly higher arch (that is, the concave arc-shaped part of the inner foot), and the talus (talus) and calcaneus (calcaneus) should be on the same straight line and perpendicular On the ground. However, with the congenital or acquired relationship, the three-dimensional configuration of the sole of each person will be different. For example, some people who are born with flat feet have lower arches or even no arches; or, when When children stand prematurely or have incorrect postures for a long time, it is easy to cause pronation of the foot.

The current insoles are usually produced in large quantities in the same shape, rather than tailored to everyone’s soles. Therefore, when purchasing insoles, users often choose softer insoles. In this way, when users step on the aforementioned In the case of an insole, the insole will give a more comfortable feeling due to its larger deformation. However, softer insoles are often less supportive. Therefore, under long-term use, it is easy to cause abnormal tension in the plantar muscles, and for people with flat feet or high arches, it will be more likely to aggravate it. Bad condition of lower extremity fascia. It can be seen from this that when choosing an insole, it is better to choose an insole with support for the sole of the foot.

As mentioned above, due to the differences in the three-dimensional configuration of the soles of each person, mass-produced insoles obviously cannot meet everyone’s needs. However, currently custom-made insoles are usually used for corrective purposes. Not only does it take several weeks, but it is also expensive. Especially the production process is cumbersome and requires a lot of specialized equipment and tools. Therefore, for the general public, it is obviously less practical. In view of this, the creator has designed an orthopedic insole that can be quickly tailored. For a brief description, please refer to Figure 1A. The orthopedic insole 10 includes an inner coating layer 11, a plurality of particles 12, and An outer covering layer 13, wherein the inner covering layer 11 itself is a gas-permeable material and is filled with the particles 12, after which the inner covering layer 11 and the particles 12 can be placed together In the air-impermeable outer covering layer 13, an air channel 131 is provided on the outer covering layer 13, and the air channel 131 is connected to the inside and outside of the outer covering layer 13.

Please refer to Fig. 1A. In production, the orthopedic insole 10 can be placed in the shaping groove 151 of a supporting fixture 15 (such as a shoe mold table). ) Can assist the user to adjust the position of the foot, so that the foot can step on the top surface of the corrective insole 10 in the correct posture (that is, the posture that meets the required correction), and at the same time, the particles 12 will also be shaped ( After completing the aforementioned shaping process, professionals can connect the air channel with special vacuum equipment (such as: vacuum pump, valve, vacuum gauge, pipe fittings, joints, etc.) Perform a vacuuming operation on the corrective insole 10 to make the particles 12 set in a state where the particles 12 are in close contact with each other and cannot continue to move, and then the air channel 131 is hermetically sealed to form the corrective insole 10 (as in Section 1B). As shown in the figure).

Although the aforementioned corrective insole 10 conceived by the inventor has a very short personalized production time (less than 10 minutes) and a far lower price compared to traditional corrective insoles, it is still not enough for the general public to use it widely. The main reason is that the orthopedic insole 10 not only requires special vacuuming and shaping auxiliary equipment (such as: shoe mold table, vibration table, sealing machine, etc.), but also requires professional assistance, which is impossible for ordinary users. Provided, so users who need it can only purchase it in at least a few special places, such as foot orthotics or insole stores. In addition, in order for the corrective insole 10 to have good corrective ability, a large number of particles 12 need to be placed in it to be able to shape the shape that meets the requirements for correction. This situation also causes the overall production cost of the corrective insole 10 Still higher than general insoles.

For the general public, the insoles used by them do not actually need to be rigorous to corrective nature, but are based on comfort and daily health care. Therefore, in the aforementioned problems (such as: the need for specialized equipment, specialty stores/places) , Professional services and higher costs), the orthopedic insole 10 will greatly reduce the general public’s willingness to buy and use. Therefore, how to effectively solve the aforementioned problems and provide the general public with more suitable products is the subject of this creation. An important topic.

In view of the fact that there are still many shortcomings in conventional insoles, the creators, relying on years of practical experience, and after many studies, trials and implementations, finally designed a personalized insole that can be quickly formed in this creation. Can effectively solve the aforementioned problems.

One purpose of this creation is to provide a personalized insole that can be quickly formed, which can be placed in a shoe or become a part of the structure of the shoe for the user's sole to step on. The personalized insole includes an outer The covering layer, a plurality of particles, at least one opening and closing element and at least one negative pressure auxiliary element, wherein the outer covering layer is made of an air-impermeable structure, and the planar configuration of the outer covering layer can be compared with that of the sole of the foot. The overall or partial plane configuration is matched, and it is provided with an air channel that can communicate with the inside and outside of the outer covering layer. At least a partial area of the outer covering layer is made of elastic or flexible non- Made of air-permeable material or structure; the opening and closing element can make the air channel exhaust outward in one direction, or can switch the air channel between a bidirectional conduction state and a bidirectional non-conduction state; the particles It can be directly or indirectly filled into the outer coating layer, so that the outer coating layer presents a predetermined thickness, and the particles can move within the outer coating layer; each of the negative pressure auxiliary components is located in the outer coating layer. In the outer coating layer, there is at least one air-containing space in it. When it is under the pressure of external force, the air in it will be discharged. Moreover, when the external force is removed, its own restoring force will also force it. Absorb external air; when the whole or part of the sole of the foot is stepped on the outer covering layer, the particles can move with the overall or partial three-dimensional configuration of the sole of the foot to complete the shaping (ie, forming), and The air in the outer covering layer will be discharged out of the outer covering layer through the air channel due to the pressure exerted by the sole or part of the sole. The negative pressure auxiliary element will also be affected by the aforementioned pressure to reduce its occupied volume. The air inside will also be discharged out of the outer coating through the air channel, and when the air channel is hermetically sealed, the pressure exerted by the sole of the foot is removed, and the negative pressure auxiliary element will be affected by its own The restoring force expands and absorbs the residual air between the particles to generate negative pressure, so that the particles are set in a state of close contact with each other and not easily displaced to obtain the personalized insole. In this way, the user does not need to With the additional use of any special equipment, it is possible to easily and quickly complete a personalized insole that conforms to the three-dimensional configuration of the sole of the foot.

The insole of this creation has a major breakthrough. Users do not need to prepare any professional equipment by themselves, and they can simply and quickly prepare their personalized insole by themselves, which means that they have the conditions for selling in convenience stores or online shopping.

This creation is a kind of personalized insole that can be quickly formed. The main purpose of the personalized insole is to be used as a general adaptable and stress-relieving insole. It does not require additional special auxiliary tools (such as special vacuum Equipment, etc.), and the user can easily produce a personalized insole that matches the three-dimensional configuration of the sole of his foot. However, the personalized insole in this creation is not excluded for corrective use. Please refer to Figure 2. In a first embodiment, the personalized insole 2 includes an outer coating 21, a plurality of particles 22, at least one negative pressure auxiliary element 23, and at least one opening and closing element 24, wherein The outer covering layer 21 is a gas-impermeable material or a gas-impermeable structure, and its periphery is hermetically sealed to form a first accommodating space therein. In addition, the planar configuration of the outer covering layer 21 can be consistent with that of the sole of the foot. The overall planar configuration matches (as shown in Figure 3A), and at least a partial area of its top surface is made of elastic or flexible air-tight materials or structures to be able to be formed in the process described later It conforms to the planar configuration of the sole of the foot, but is not limited to this. In other embodiments of the present creation, the planar configuration of the outer coating layer 21 can also correspond to a part of the sole of the foot (for example, corresponding to the phalanges, midfoot bones or The plane configuration of the local part of the heel bone is matched, and it is first Chen Ming.

Please refer to Figure 2 again, the outer coating layer 21 can be provided with at least one air passage 211, which communicates with the inside and outside of the outer coating layer 21, so that the air in the first containing space can pass through the The air channel 211 flows out of the outer coating layer 21. In addition, in the first embodiment, the particles 22 can be directly filled into the outer coating layer 21, so that the outer coating layer 21 exhibits a predetermined thickness and maintains a soft state, and, The particles 22 can move within the outer coating layer 21. In addition, the personalized insole 2 is also provided with an opening and closing element 24, which is air-tightly mounted on the outer covering layer 21 at a position corresponding to the air passage 211, for example, can be arranged inside the air passage 211 , Or arranged on the inside and/or outside of the outer covering layer 21. In the first embodiment, as shown in FIG. 2, the opening and closing element 24 is located on the inner side of the outer covering layer 21. In addition, the opening and closing element 24 can make the air passage 211 in a unidirectional exhaust state, or can make the air passage 211 switch between a bidirectional conduction state and a bidirectional non-conduction state. In addition, in order to prevent the particles 22 from flowing out of the outer coating layer 21 through the air channel 211, the opening and closing element 24 can also be provided with a blocking structure (such as a filter) to block the particles at the same time. 22 through the air channel 211 outflow effect.

Furthermore, please refer to FIGS. 2 and 3A again. In order to avoid the complexity of the diagram, the particles 22 are omitted in the diagram 3A. The negative pressure auxiliary element 23 can be located in the outer coating layer 21, and its position and number can be determined according to actual needs. As shown in Fig. 3A, there can be only a single negative pressure auxiliary element 23; or, as shown in Fig. 3B As shown in the figure, there can be a plurality of negative pressure auxiliary elements 23; in addition, the negative pressure auxiliary element 23 can generally be located in the outer coating layer 21 adjacent to the bottom surface, and the top surface of the negative pressure auxiliary element 23 can be stacked with the particles 22. The characteristic of the negative pressure auxiliary element 23 is that when it is deformed (reduced) by an external force, it will generate a restoring force, and when the external pressure disappears, it can restore itself to its original state. The negative pressure auxiliary element 23 itself has at least one air-containing space 26. When it is compressed and deformed (reduced) by an external force, the air in the air-containing space 26 inside will be discharged. On the contrary, when the external force disappears , Its own restoring force will also force it to suck external air into each of the air-containing spaces 26. For example, in the first embodiment, the negative pressure auxiliary element 23 can be an open porous elastic material (such as foam), and the collective pores or pores thereon are the air containing space 26. The term “open” mentioned above means that the air-containing space 26 is directly connected with the external space of the negative pressure auxiliary element 23. The “open” mentioned in the subsequent embodiments is also the same as the aforementioned definition.

Please refer to Figures 2 and 3A again. When the user’s soles (whole or part) step on or apply pressure on the top surface of the outer covering layer 21, the particles 22 move along with the three-dimensional configuration of the soles of the feet. The shaping (ie, forming) is completed, and the air in the outer covering layer 21 will be discharged out of the outer covering layer 21 through the air channel 211 due to the pressure exerted by the sole of the foot; and the negative pressure The auxiliary element 23 will also be affected by the aforementioned pressure to reduce its occupied volume, and the air in the air containing space 26 will also be discharged from the negative pressure auxiliary element 23, and then discharged to the outer coating layer 21 through the air channel 211 outside. Moreover, when the user hermetically seals the air passage 211 through the opening and closing element 24 so that air cannot flow into the outer coating layer 21 from the atmospheric side, and removes the pressure exerted by the sole of the foot, the negative pressure auxiliary element 23 will expand due to its own restoring force, and will absorb a relatively large proportion of the residual air between the particles 22 to form a negative pressure in the outer coating layer 21, so that the particles 22 are shaped in close contact with each other. The state of being leaning and not easily displaced can be used to obtain the personalized insole 2 (as shown in Figure 4).

For the user, the forming of the personalized insole 2 mainly needs to go through two stages of "forming" and "setting". In the "forming" stage, the user can place the soles of the feet on the outer covering layer 21 and apply pressure. At this stage, only the air in the outer covering layer 21 is allowed to pass through the air channel 211 in one direction to be discharged to Outside the outer covering layer 21; in the "setting" stage, the soles of the user's feet will leave the outer covering layer 21 to remove the pressure exerted by it. Air flows unidirectionally through the air channel 211 to the inside of the outer coating layer 21. As mentioned above, the opening and closing element 24 needs to meet one of the following two conditions:

(1) Regardless of the "forming" stage and the "setting" stage, the air passage 211 is only in one-way outward exhaust mode; according to the aforementioned conditions, the opening and closing element 24 can be achieved by using a check valve, which means, Airtightly connect a check valve with a one-way outward exhaust direction to the air passage 211 (for example, located inside or outside the air passage 211); or

(2) In the "forming" stage, the air passage 211 is in a bidirectional state, and in the "setting" stage, the air passage 211 is transformed into a bidirectional non-conducting state. According to the foregoing conditions, the opening and closing element 24 can be achieved by means of plugs, airtight tapes, valves or other means; therefore, in the "forming" stage, the air channel 211 is bidirectionally conductive, and pressure is applied to the sole of the foot to complete the shaping. After the air is discharged and the sole of the foot is still applying pressure, use a plug or airtight tape to manually plug or stick the air channel 211, and then remove the sole of the foot to apply force, which completes the "setting" stage.

According to the needs of use, the design of the negative pressure auxiliary element 23 can have various considerations and can achieve different effects:

(1) As shown in Figures 3A and 3B, the position covered or placed by the negative pressure auxiliary element 23 can be: (1-1) covering the entire insole; (1-2) covering the forefoot area; (1- 3) Cover the arch area; (1-4) Cover the heel area; or (1-5) a combination of two or more of the foregoing.

(2) According to the material and type of the negative pressure auxiliary component 23, the following types can be roughly distinguished:

(2-1) Open porous elastic material, such as: foam, sponge, etc., and can be a single whole or pieced together by multiple independent elements; the aforementioned "porosity" means that the material itself has Many pores or voids, collectively these pores or pores, can be regarded as the air-containing space 26;

(2-2) Open hollow elastomers, including: open hollow elastic round tubes, open hollow flat elastomers, open hollow spherical elastomers and open hollow elastic particles, etc.; wherein, the open hollow Elastic particles refer to the particles filled in the outer coating layer, which have a hollow interior, and the hollow interior is directly connected to the outside of the particles. Therefore, in addition to the function of the particle itself, it can also serve as The negative pressure auxiliary component is used;

(2-3) The double check valve structure is a non-open hollow elastic body, and is provided with a first outlet and a second outlet respectively communicating from the hollow interior to the exterior, which are respectively airtightly connected A first check valve and a second check valve; the design of the first check valve is such that the air outside the negative pressure auxiliary element can only flow into the hollow interior (that is, the air-containing space 26) in one direction , And the second check valve allows the air inside the hollow (that is, the air-containing space 26) to flow out to the outside of the negative pressure auxiliary element only in one direction.

(3) In addition, please refer to Figure 5 (it is the AA heel cross-sectional view of the molded insole in Figure 3B). When the user is walking, the upper half HU of the personalized insole 2 The particles 22 are shaped in close contact with each other and are not easily displaced due to the influence of negative pressure. Therefore, their overall hardness is relatively high. At the same time, the negative pressure auxiliary element 23 of the lower half HD of the personalized insole 2 can itself be The volume changes with the external force, so it has cushioning ability. Therefore, the personalized insole 2 is provided with a negative pressure auxiliary element 23, in addition to providing support for the sole of the foot, it also has cushioning properties;

(4) Viewed from the longitudinal section of the personalized insole 2, as shown in Figure 4, the negative pressure auxiliary element 23 occupies a part of the volume, so the number of particles 22 used can be greatly reduced to reduce the personalized insole 2 At the same time, it can still be molded into a three-dimensional configuration of the sole of the user's foot.

In the second embodiment of the present creation, the negative pressure auxiliary element used is not limited to block-shaped foam, but can be an open hollow elastic body. Here, a strip-shaped hollow elastic tube is used to represent the description, such as As shown by the plural hollow elastic tube bodies (negative pressure auxiliary element 33) at the top of Fig. 6, the open hollow elastic tube body can also be made of air-permeable materials. Therefore, in addition to the larger air-capacity in the tube itself In addition to the space 36, a plurality of small air-containing spaces (that is, holes and pores) in the pipe wall can be added; the air discharged by the negative pressure auxiliary element 33 can finally pass through the air channel 211 (such as 6) is exhausted by the air channel 211) in the middle on the right. In the second embodiment, the opening and closing element 24 is an airtight tape and can be located on the outer side of the outer coating layer 21.

Please refer to Figure 6 again. In this second embodiment, a negative pressure auxiliary element 43 with a double check valve structure (such as the oblate non-open hollow elastic body at the bottom of Figure 6) is used. It is made of airtight material or structure, and is airtightly connected to a first check valve 431 and a second check valve 432, wherein the first check valve 431 can only make the negative pressure auxiliary element 43 The outside air flows into the hollow interior (that is, the air-containing space 46), as shown in the direction of the arrow above the first check valve 431 in Figure 6; the second check valve 432 can only make the negative pressure auxiliary element 43 hollow The air in the inside (that is, the air-containing space 46) flows out to the outside, as shown in the direction of the arrow below the second check valve 432 in Figure 6, and is in airtight communication with the air passage 211; when the outer coating layer 21 is sufficient When the heel is repeatedly stepped on, squeezed and released by an external force, the air in it can flow out to the outer casing through the first check valve 431, the air containing space 46, the second check valve 432 and the air passage 211 in sequence. Outside the cladding 21. It is particularly mentioned here that when the user steps on the negative pressure auxiliary element 43 continuously, a relatively large negative pressure can also be formed in the outer coating layer 21. The first check valve 431 and the second check valve 432 are only for air to flow in one direction. Therefore, as long as they can achieve the aforementioned structure that only allows air to flow in one direction, for example, duckbill valve, cutoff valve Air check valves, etc., all belong to the first check valve 431 and the second check valve 432 referred to in this creation.

Please refer to FIG. 7A. In the third embodiment of the present invention, the particles 22 can be filled into the second containing space of an inner coating layer 25, wherein the inner coating layer 25 is made of It is made of breathable material (such as elastic or flexible breathable fabric or breathable plasticized film), and its planar configuration can match the overall or partial planar configuration of the sole, so that the inner covering layer 25 presents a With a predetermined thickness to maintain a soft state, the particles 22 can move within the inner coating layer 25, and their particle size will be larger than the air-permeable aperture of the inner coating layer 25, so that the particles 22 will not be exposed to external forces. The inner cladding layer 25 is released by squeezing. Moreover, the periphery of the inner coating layer 25 can be sealed, and it can be placed in the outer coating layer 21 together with the particles 22 inside, which means that the particles 22 are indirectly placed in In the outer coating layer 21. In addition, the negative pressure auxiliary element 23 and the opening and closing element 24 can be located outside the inner coating layer 25. In this way, during the production process, the negative pressure auxiliary element 23, the opening and closing element 24 and the inner coating layer 25 can be combined. Putting them into the outer coating layer 21 is not only relatively simple in procedure, but also enables the negative pressure auxiliary element 23 and the opening and closing element 24 to be located at the desired position. However, in other embodiments of the present invention, the negative pressure auxiliary element 23 can also be installed in the inner coating layer 25 together with the particles 22, which will be described first.

Continuing, please refer to Figure 7B. When the user’s foot steps on the top surface of the outer covering layer 21, the particles 22 in the inner covering layer 25 follow the three-dimensional structure of the sole of the foot. The shape displacement completes the shaping, and the air in the inner covering layer 25 will be discharged to the inner covering layer 25 due to the pressure exerted by the sole of the foot; in addition, the negative pressure auxiliary element 23 is also under the pressure of external force. Air is discharged. The air discharged from the inner coating 25 and the negative pressure auxiliary element 23, together with the air originally in the outer coating 21, is discharged to the outer coating 21 through the air channel 211 outside. In addition, the air channel 211 is hermetically sealed. When the outer coating layer 21 is no longer stressed (that is, no longer stepped on), the restoring force of the negative pressure auxiliary element 23 will force it to suck outside air. As a result, the shaped particles 22 in the inner covering layer 25 are shaped in close contact with each other and not easily displaced due to the influence of negative pressure, so as to obtain the personalized insole 2.

In addition, please refer to Figure 7C, in order to make the personalized insole 2 to maintain its shape for a long time, it can also be shaped after completion (that is, the particles 22 are shaped in close contact with each other and are not easy to Displacement state), and after the air passage 211 has been hermetically sealed, the heating operation is performed. Among them, the particles 22 can be made of thermoplastic elastomer materials (such as TPU, TPEE, TPS, TPR, SEBS, etc.) with a low melting point or a low initial melting temperature (such as 60°C to 85°C), and the melting point is or The initial melting temperature will be lower than the other components of the personalized insole 2 (such as the outer coating 21, the negative pressure auxiliary component 23, etc.), which means that when the particles 22 are in a molten state, the personalized insole 2 The other components can also maintain their integrity without being molten. In addition, the heating operation can be performed with hot boiling water, an oven, a hair dryer, or a microwave oven, without the need to use professional heating equipment, so as to improve the convenience of personal use. During the heating operation, at least the surface of the particles 22 will be in a molten state, so that the adjacent particles 22 can be welded into one body, thereby solidifying the personalized insole 2 with a long life. In this way, if the outer coating layer 21 or the inner coating layer 25 is damaged under long-term use, since the particles 22 have been bonded together, the personalized insole 2 can still remain on the original sole The three-dimensional configuration can effectively extend the service life of the personalized insole 2.

In addition to making the particles 22 with thermoplastic elastomer materials, in other embodiments of the present invention, the particles 22 can also be uniformly mixed with a plurality of bonding materials 27, so that the bonding materials 27 can be uniformly attached to each of the bonding materials. The surface of the particles 22 (as shown in Figure 8), wherein the bonding material 27 can be in the form of powder, liquid paste... etc., and it includes adhesive materials (such as: TPU hot melt adhesive, EVA hot melt adhesive) …Etc.) 271 and/or Absorbent (such as infrared absorbing material, electromagnetic wave absorbing material…etc.) 273, the adhesive material 271 and the absorbent material 273 can be attached to the surface of the particles 22 as shown in Fig. 8, Or completely coat the surface of the particles 22. In addition, the melting point of the bonding material 27 will be lower than the melting point of other elements of the personalized insole 2 (such as the particles 22, the outer coating 21, the negative pressure auxiliary element 23, etc.), and the bonding material 27 and these The particles 22 can be directly or indirectly packed into the outer coating layer 21. When the personalized insole 2 further includes an inner covering layer 25, the particle size of the bonding materials 27 can be larger than the air-permeable aperture of the inner covering layer 25, so that the bonding materials 27 can only be in the inner covering layer 25. Displacement within 25. After the heating operation is performed, the bonding materials 27 can be melted to fuse the adjacent particles 22 into one body, thereby solidifying the personalized insole 2 with a long life.

It is particularly mentioned here that the personalized insole 2 can be reshaped without heating operation. The user only needs to open the air channel 211 to allow outside air to enter the outer coating layer 21. In addition, the number of air channels 211 in this creation is not limited to only one, but can also be multiple (as shown in Figure 6), when one of the air channels 211 is occupied (as in the second embodiment, the air channel 211 at the bottom is When it is exclusively occupied by the second check valve 432), the other air channel 211 can be opened to allow outside air to enter the outer coating layer 21. When necessary, the air channel 211 can also be used to fill or remove particles 22.

Here is an explanation of the manufacturing process of the personalized insole 2 of this creation. Please refer to Figures 2 and 9. In step (501), a filling operation is performed. According to the design of the personalized insole 2, the The opening and closing element 24 and the negative pressure auxiliary element 23 are arranged on a predetermined position of the outer coating layer 21, and the particles 22 are directly or indirectly filled into the outer coating layer 21 (for example, the particles 22 can be first After being filled into the inner coating layer 25, the inner coating layer 25 is installed in the outer coating layer 21), so that the outer coating layer 21 has a predetermined thickness, and the particles 22 It can move within the outer coating layer 21 (or the inner coating layer 25), and then hermetically seal the filling port to complete the filling operation; after that, in step (502), a pre- The molding operation is usually performed at the factory, which is based on a preliminary three-dimensional plantar configuration. The aforementioned "preliminary three-dimensional plantar configuration" generally refers to some representative three-dimensional plantar models, for example, suitable for most people. The foot shape or the foot shape designed according to the user's expectations, after which the filled insole is laid flat or placed on a support fixture (ie, shoe mold table), so that the opening and closing element 24 makes The air channel 211 is in a unidirectional outward exhaust state or a bidirectional conduction state. The preliminary three-dimensional configuration of the sole is placed on the outer covering layer of the insole, and appropriate pressure is applied to make the particles 22 Following the displacement of the three-dimensional configuration of the sole to complete the shaping, an air extraction device (such as a vacuum pump) is used to draw air to the outer coating layer 21 through the air channel 211 to obtain a strong shaping (higher vacuum). ) Effect, and finally the air channel is hermetically sealed to complete the pre-forming operation. This operation allows the insole to maintain a representative state for storage for a long time, and it will also be convenient for users to use in the future.

In addition, in step (503), a forming operation is performed. The air pressure inside and outside the outer coating layer 21 is the same or substantially the same, and the opening and closing element 24 makes the air channel unidirectional outward. In the case of the exhaust state or the bidirectional conduction state, under the state that the user's sole or part of the sole of the foot is stepped on and pressed on the outer coating layer 21, the particles 22 can be made to follow the entire or part of the sole of the foot. The partial three-dimensional configuration is displaced to complete the shaping, and the air in the outer covering layer 21 will be discharged to the outside of the outer covering layer 21 through the air channel 211 due to the pressure applied by the sole or part of the sole. The negative pressure auxiliary element 23 will also be affected by the aforementioned pressure to reduce its occupied volume, and the air in it will also be discharged to the outside of the outer coating 21 through the air channel 211. At this time, the outer coating 21 The top surface of 21 will form a three-dimensional configuration that matches and conforms to the shape of the user's sole; in step (504), a certain shape operation is performed to make the opening and closing element 24 maintain the air channel to exhaust in one direction. State or converted to a bidirectional non-conducting state, so that the air outside the outer covering layer 21 cannot flow into the outer covering layer 21. After the pressure exerted by the sole of the foot is removed, the negative pressure auxiliary element 23 will be affected by itself. The restoring force expands and absorbs the residual air between the particles 22, so that the particles 22 are shaped in close contact with each other and not easily displaced due to the influence of negative pressure, so that the personalized insole 2 is obtained. Furthermore, in step (505), a heating operation is performed so that the adjacent particles 22 can be directly or indirectly welded into one body, thereby solidifying a long-life personalized insole 2; and, for some materials When heating, gas will be released, which will destroy the original negative pressure state and change the set shape. Therefore, in step (505), the mode of vacuuming the insole while heating can be used to ensure its three-dimensional configuration Not to be changed. In the above-mentioned production process of this creation, the steps (502) and (505) can be omitted according to product requirements.

In particular, when the opening and closing element 24 uses a check valve, it has the following advantages:

1. The personalized insole 2 can be directly placed in the shoe. When stepping or walking, the forming (forming and shaping) of the personalized insole 2 will be automatically completed, which eliminates the need to be outside the shoe first and manually Perform forming and shaping operations, and then put the personalized insole 2 into the shoe for use after completion. The main reason is that if the opening and closing element 24 is a plug, an airtight tape, etc., the switch between conduction and non-conduction of the air passage 211 generally needs to be operated manually, so it needs to be performed outside the shoe.

2. It conforms to the three-dimensional configuration of the sole of the user in daily actions.

3. In daily operations, the vacuum will be automatically filled (to avoid the trouble of micro-leakage).

4. Personalized insoles that meet the needs of special configurations can be molded. For example, in order to achieve the purpose of correction, the general flatfoot patients hope that the three-dimensional configuration of the insole can conform to the three-dimensional configuration of the sole of the foot when the sole is slightly compressed (or uncompressed), or hope to have a tilt in a certain place or direction , Protrusions and other special configuration requirements (such as stimulating acupuncture points), if you use the check valve insole, you can manually squeeze the outer coating layer, so that the outer coating layer (and/or inner Part of the air in the coating layer is slowly discharged to the outside of the outer coating layer through the air channel under control. When a slight negative pressure is reached, the particles can appear to contact each other and keep them from moving randomly. However, when a finger is applied to the outer coating layer, the particles can be easily moved and the three-dimensional shape after the movement can be maintained; use this manual method to compare with the foot, and use appropriate Tools are used to assist the shaping, which can easily and quickly complete the shaping operation for the special configuration requirements, and finally strengthen the establishment of negative pressure to complete the shaping operation, that is, to shape the personalized insole that meets the special configuration requirements. 2
