Technical Field
The present invention relates to a shoe insole, and more particularly, to a method of manufacturing a personal adaptive insole that is optimized to fit physical characteristics such as walking habits of a user, and a personal adaptive insole manufactured by the method.
Background
For a human walking upright, the feet are more important than any organ, and for good health and longevity, it is necessary to manage the feet well. In particular, from a medical point of view, it is known that there are acupuncture points in the foot that connect with various organs of the body, and based on this reason, the foot is also called the second heart.
Various types of shoes are available, such as the most common sports shoes, which are composed of main components such as an upper, an insole, a midsole, and an outsole.
The insole is installed in an inner space surrounded by the upper, and is a portion that the sole of the foot directly contacts when a user wears the shoe. In order to make the wearing feel good and to give a beneficial influence to the feet and the body, research into the insole is being actively pursued. Furthermore, in modern people who live on shoes all day long, foot diseases such as beriberi are often caused because good ventilation is not achieved, and pain or discomfort is often caused in the feet, ankles, knees, and waist due to large or small impact on the soles of the feet caused by long-time walking, and in severe cases, even deformation of the body shape is caused, which makes walking difficult.
In order to eliminate such problems, various shoes and insoles for relieving impact when walking have been proposed.
As a representative prior art, "an insole having a cushioning effect and a method of manufacturing the same" are known in korean patent laid-open No. 10-0758023.
Fig. 1 is a perspective view of a conventional insole having a cushioning effect, and as shown in the drawing, the conventional insole having a bottom plate made of synthetic resin and a cloth attached thereto is characterized by comprising a cushioning member 10, wherein the cushioning member 10 is joined to a bottom surface 114 of a heel part 112 of the bottom plate 110, is made of an elastic synthetic resin material, contracts and recovers according to a load applied during walking to absorb an impact force, the cushioning member 10 has a plurality of first elastic protrusions 12 formed to protrude downward from the bottom surface 114, and a plurality of wrinkles 13 formed to contract and recover in the vertical direction are formed around the first elastic protrusions 12.
However, since shoes, which are generally mass-produced industrially, are manufactured in consideration of physical properties of ordinary people, there is a limitation that optimal satisfaction cannot be given to each user.

Detailed Description
Hereinafter, a method of manufacturing a personal adaptive insole according to the present invention and a personal adaptive insole according thereto will be described in more detail with reference to the accompanying drawings. On the other hand, the illustrated drawings are diagrams showing one embodiment related to the technical idea of the present invention.

First, a method of manufacturing the personal adaptive insole will be described with reference to the accompanying drawings.
The manufacturing method of the personal adaptive insole of the present invention may be comprised of the 1 st to 6 th steps, and the 1 st step S10 is a step of preparing the insole body 10.
The insole body 10 is formed substantially on the sole of a foot and is molded of a material having cushioning properties and restoring force, such as EVA. The material for the insole body may be a known material, and preferably, a heat-resistant EVA (E265F) material may be used.
More preferably, the insole body 10 is made of a cushioning material, and is formed by combining a plurality of layers having different hardness from the bottom, each of the first layer 11, the second layer 12, and the third layer 13.
For example, the hardness of the first layer 11 is set to 35 degrees and the maximum hardness is set to 30 degrees, the second maximum hardness is set to 30 degrees, and the hardness of the second layer 12 is set to 20 degrees and the minimum hardness is set to maintain the shape and generate a sufficient restoring force. The first layer 11, the second layer 12, and the third layer 13 constituting the insole body 10 may be made of different materials or may be made of the same material but having different hardness.
A predetermined skin member 14 may be bonded to the third layer 13, which is the uppermost surface of the inner sole body 10, and a merino wool material may be used as the skin member 14, in addition to a known fiber. When the skin member of wool material is used, not only the touch is soft, but also moisture absorption can be well achieved, thereby helping the health of the foot.
After preparing a proper insole body 10, in a 2 nd step S20, the support body 20 is bonded to the lower surface of the insole body 10. The support body 20 is made of a Shape Memory Polymer (SMP) material, and covers the entire lower surface of the insole body 10.
More preferably, when the support body 20 is coupled to the lower surface of the insole body 10, the plurality of regions are formed into the pressure concentration part 21 having a relatively thin thickness by injection molding. Here, the pressure concentration portion 21 refers to a plurality of regions where a large amount of foot pressure locally occurs in the sole region when walking on the basis of a general human, and the pressure concentration portion 21 also constitutes a part of the support body 20 and has a relatively small thickness compared to other regions. For example, the basic thickness of the support body may be 3mm, while the thickness of the pressure concentration portion may be 1.5 mm.
As shown in fig. 2, in the case of ordinary people, if the sole pressure during walking is measured, the pressure measured in 5 areas is generally high, and such a place may be selected as the pressure concentration portion 21.
After the support body 20 is coupled to the lower surface of the insole body 10, a predetermined heat is applied to the support body 20 so that the shape of the support body 20 can be changed when pressure is applied thereto in step S30 3. As described above, the support body 20 is bonded to the lower surface of the insole body 10 as a Shape Memory Polymer (SMP), and the Shape thereof may be changed according to the pressure distribution when heated at 70 to 90 ℃ for about 30 to 50 seconds in terms of material characteristics. As a method of heating the support 20, hot air may be applied to the surface of the support, or heat may be applied while being put in a chamber.
Next, in step 4S 40, the support body 20 is placed on a predetermined shaped pad P, which is a member such as a square pad having a predetermined thickness and excellent cushioning and restoring forces, and an eco-memory foam can be used. More specifically, the molded pad was formed using a 50K _ MDI foaming agent and had a length of 600mm, a width of 400mm and a height of about 100 mm.
Then, in step S50 of step 5, the foot pressure of the user is applied to the upper surface of the insole body 10 in a state where the support body 20 is opposed to the molded pad P, and the shape of the support body 20 is deformed in accordance with the foot pressure, thereby fixing the insole body 10 and the support body 20 in the shape of the sole of the user.
That is, since the support body 20 placed on the molded pad P is in a state of being heated to a deformable degree, when a user steps on the insole body 10, foot pressure is applied downward, and thus the molded pad P generates depressions having different patterns at different positions according to the shape of the sole of the foot and the distribution of foot pressure. The support body 20 is also deformed so as to correspond to the depression of the molding pad P, and as time passes, the support body 20 is fixed in a deformed shape while being cooled, and the insole body 10 coupled to the support body 20 is also bent so as to correspond to the deformation of the support body 20.
Next, the 6 th step S60 is performed, and in the 6 th step S60, the pressure distribution pad 30 is attached to the pressure concentration portion 21, thereby completing the insole.
More specifically, the 6 th step S60 may be subdivided into a 6 th-1 st step S60-1 and a 6 th-2 nd step S60-2.
The insole manufactured through the 5 th step S50 is referred to as an intermediate insole, and in the 6 th-1 st step S60-1, the intermediate insole is placed on the sole pressure gauge T and stepped on by the user, thereby measuring sole pressure distribution of both feet.
In step S60-2, the information on the distribution values of the sole pressure measured in step S60-1 of step 6-1 is analyzed, and the appropriate pressure distribution pads 30 are attached to the respective pressure concentration portions 21. That is, there are a plurality of pressure concentration portions 21, and each of these pressure concentration portions 21 is a portion where a pressure is formed higher than other regions. However, since the sole pressure distribution values of the pressure concentration portions 21 are also different, the most suitable pressure distribution pads 30 are attached to the pressure concentration portions 21 in consideration of such differences.
For example, as shown in fig. 2, in the present embodiment, there are a total of 5 pressure concentration portions 21, which are referred to as a first pressure concentration portion 21a, a second pressure concentration portion 21b, a third pressure concentration portion 21c, a fourth pressure concentration portion 21d, and a fifth pressure concentration portion 21 e.
The sole pressure of the pressure concentrating portion 21 and the structure of the pressure distribution pad 30 corresponding thereto can be shown in table 1 below.
TABLE 1
| Pressure value of sole | Pressure-dispersing mat | |
| First pressure concentration part | Big (a) | Small hardness value |
| Second pressure concentration part | In | Hardness value of |
| Third pressure concentration part | Small | High hardness value |
| Fourth pressure concentration section | In | Hardness value of |
| Fifth pressure concentration part | Small | High hardness value |
In this manner, in consideration of the sole pressure values of the pressure concentration portions 21 having different pressures, appropriate pressure distribution pads 30 corresponding to the pressure concentration portions 21 are attached to the pressure concentration portions 21 so that the pressure distribution can be distributed.
The pressure distribution pad 30 may be provided in various thicknesses and hardnesses to be used by selective combinations, for example, the pressure distribution pad 30 may have 3 kinds of thicknesses of 1.5mm, 2.5mm, and 3.5mm, and may have 3 kinds of thicknesses of 20 degrees, 30 degrees, and 40 degrees in terms of hardness (a hardness meter is a product code C-ASKER, a stylus height of 2.54mm, and a C1L type with a pressing width of 44 mm).
By using the pressure distribution pads 30 having various thicknesses and hardnesses in this manner, the user can use the pressure distribution pad 30 in a manner that the pressure concentration portion 21 is bonded with the most suitable pressure distribution pad 30 in accordance with the combination most suitable for the user.
On the other hand, the method of manufacturing the personal-adapted insole according to the present invention may further include step 7S 70. Although the personally adapted insole may be completed through the 6 th step S60, the degree of completion of the product may be improved by verifying whether the personally adapted insole is accurately manufactured through the 7 th step S70.
For this purpose, in step S70, the insole completed in step S60 is placed on the sole pressure measuring instrument again, and the user steps on the insole to apply a load, thereby measuring the sole pressure distribution again, and verifying the effectiveness of the pressure distribution pad 30.
That is, if the accurate pressure distribution pads 30 are attached to the pressure concentration portions 21, it is confirmed that the pressure distribution values measured in step S7 and step S70 are uniformly distributed compared to the pressure distribution values measured in step S60.
By repeating step 7, step 70, and selecting the pressure distribution pad 30 that is most suitable for each pressure concentration portion 21, the pressure distribution in the entire insole is distributed, and the fatigue of the foot can be reduced, and the walking comfort can be provided.
More preferably, in the method of manufacturing the personal adaptive insole of the present invention, the support body 20 may be injection-molded using data obtained by measuring the pressure of the user' S foot using the foot pressure measuring instrument T in step S20 of 2, so that the positions of the plurality of pressure concentration portions 21 may be more accurately measured.
In other words, the foot pressure data required in step S20 2 may be information obtained based on the average foot of an ordinary person, or the position of the pressure concentration portion may be selected using data obtained by directly measuring the foot pressure of an actual user, in some cases.
Next, a description will be given of the personal-fit insole manufactured by the method for manufacturing the personal-fit insole as described above.
The personal adaptation type insole produced by the manufacturing method of the present invention includes an insole body 10 and a support 20 coupled to a lower surface of the insole body 10, the insole body 10 may be made of a material having cushioning and restoring force such as EVA (E265F), the insole body 10 is formed by sequentially coupling a first layer 11, a second layer 12, and a third layer 13 from a lower portion, and the first layer 11 has the highest hardness, the third layer 13 has the second highest hardness, and the second layer 12 between the first layer 11 and the third layer 13 has the lowest hardness.
Further, the outer skin member 14 may be coupled to the third layer 13 of the insole body 10, and the outer skin member 14 may be made of a fleece material.
Further, more than one support rib 21-1 may be formed at the pressure concentration portion 21, and the support groove 31 may be formed corresponding to the support rib 21-1 at one surface of the pressure distribution pad 30, so that the support rib 21-1 is inserted into the support groove 31 when the pressure distribution pad 30 is coupled to the pressure concentration portion 21, thereby enabling more accurate disposition.
On the other hand, more than one rib groove 21-2 may be formed in the pressure concentration portion 21, and a rib protrusion 32 corresponding to the rib groove 21-2 may be formed on one surface of the pressure distribution pad 30, thereby inserting the rib protrusion 32 into the rib groove 21-2, thereby coupling the pressure distribution pad 30 with the pressure concentration portion 21.
By providing the support ribs 21-1 or the rib grooves 21-2 in the pressure concentration portion 21, and the support grooves 31 or the rib protrusions 32 in the pressure distribution pad 30, and inserting and coupling them, the pressure distribution pad 30 can be accurately provided and the pressure distribution efficiency at the support body 20 can be improved.
Further, when the rib groove 21-2 is provided to the pressure concentration portion 21, it can move more flexibly, thereby having an additional effect that it is possible to provide a comfortable feeling when walking.
Further, the pressure distribution pad 30 coupled to the pressure concentration portion 21 may be provided in plural with different thicknesses or hardnesses, so that the user may select or use a pressure distribution pad suitable for himself.
In other words, the pressure distribution pad 30 is provided in various thicknesses and hardnesses, and thus can be used by selective combinations, for example, the pressure distribution pad 30 may have 3 thicknesses of 1.5mm, 2.5mm, and 3.5mm, and may have 3 thicknesses of 20 degrees, 30 degrees, and 40 degrees in terms of hardness (hardness is a product code C-ASKER, a stylus height of 2.54mm, and a C1L type with a pressing web of 44 mm).
By using the pressure distribution pads 30 having various thicknesses and hardnesses in this manner, the user can attach the most suitable pressure distribution pad 30 to the pressure concentration portion 21 in accordance with the combination most suitable for the user.
For example, the pressure distribution pad 30 having a thickness of 1.5mm and a hardness of 30 degrees may be bonded to the first pressure concentration portion, and the pressure distribution pad 30 having a thickness of 3.5mm and a hardness of 20 degrees may be bonded to the second pressure concentration portion.
The pressure distribution pad may be formed by combining different materials, and may be provided in various thicknesses or may have different hardness even with the same material.
As described above, the method for manufacturing the personal adaptive insole according to the present invention and the personal adaptive insole manufactured by the same have advantages of providing walking comfort and helping the foot and the overall body shape by measuring the actual foot pressure of the user and coupling the pressure distribution pad to the optimum position to more uniformly distribute the foot pressure acting on the sole of the foot.
