Problems solved by technology

[0002] The insole is a very important part of the shoe. The insole on the market is mainly composed of three parts: the bottom surface of the insole, the surface of the insole, and the middle part of the insole. It is a direct pressure-bearing part in contact with the foot and the shoe body. It has the function of dispersing and concentrating pressure. The protection of the soles of the feet largely determines the comfort of people wearing shoes. For the shape, contour and surface changes of the soles of the human feet, the impact of the insole is very obvious, and the human body needs to wear shoes for activities in daily life, thus Different gaits and sole shapes are produced continuously and changeably, so the contact between the insole and the sole of the foot is very changeable and complicated. However, most of the current insoles are designed and produced by plane, mainly including cloth insoles, leather insoles, foam insoles, etc. The design is not optimized for changes in human feet and activity pressure. For some patients with foot diseases, ordinary insoles are not suitable for them

Embodiment 1

[0065] Step s24 in this embodiment specifically includes the following sub-steps:

[0066] Step s241: define the ratio between D1 and D2 as X, that is, D1 / D2=X, and determine the scope of X;

[0067] The present invention collects data through a pressure sensor. For the foot, there is an arch, which is composed of arched joints of tarsal bones and metatarsal bones, and tissues with elasticity and contraction force such as ligaments and tendons on the soles of the feet. A protruding upward arch, which can be divided into longitudinal arch and transverse arch. The main function of the arch of the foot is to disperse the gravity from the ankle joint through the talus forward to the head of the metatarsal bone, and transmit it backward to the calcaneus to ensure that the sole of the foot can stand upright. The stability of the support. The arch of the foot usually protrudes upwards, so when the user walks or stands on the pressure plate, the arch of the foot cannot touch the pres...

Embodiment 2

[0076] This embodiment is an instruction for making insoles for users with flat feet. One of the differences between this embodiment and Embodiment 1 is that step s242 is: see Figure 6 , when X≤0.5, the angle between the plane where the inner area of ​​the plane model is located and the horizontal plane is set to 2 degrees, and the direction of the included angle is inward, so that the outer edge of the inner area is higher than the inner part, and the foot can be controlled When the foot is everted when walking, the grid density of the inner area is set to 1 to 3 times that of other areas, and the thickness of the area where the plane model corresponds to the arch position is adjusted to half of the preset thickness; The inner side of the plane model is the width between the outer side of the thumb area and the inner edge, and the length is between the forefoot and the rear heel, which is Figure 6 B area in;

[0077] Patients with severe flat feet do not have the normal ho...

Embodiment 3

[0080] This embodiment describes how to make insoles for users with normal feet but with collapsed transverse arches, and aims to introduce how to combine the plane model with plantar pressure data to obtain the final 3D insole data. In this embodiment, X=2, which belongs to the range of normal feet, and the thickness of the arch of the foot is the preset thickness, that is, the preset thickness mentioned in the present invention, which is based on the normal feet, and the thickness of other patients Then add the preset thickness to make relevant adjustments, the mesh density of the arch of the foot can be consistent with other parts, see Figure 7 , the processor can analyze according to the sole pressure data (the processor can also have a display, according to the sole pressure data can be displayed in the plane model, marked with different colors, different colors represent different force ranges) the soles of the feet Excessive pressure in the C area of ​​the forefoot mea...

Abstract

The invention relates to a method for manufacturing a rehabilitation insole. The method comprises the following steps that foot data of a user are collected, and the foot data include foot sole pressure data collected through a pressure sensor and foot dimension data obtained by processing the foot sole pressure data; a planar model of the insole is generated according to the collected foot dimension data, three-dimensional model data of the insole are obtained through processing according to the planar model and the foot sole pressure data, and the three-dimensional model data are sent to a three-dimensional (3D) printer; and the corresponding finished insole is printed through the 3D printer according to the three-dimensional model data. The method for manufacturing the rehabilitation insole is suitable for patients suffering from foot diseases, the collected foot sole pressure data are processed and converted into thickness data of different areas of the insole, and the corresponding insole can be manufactured according to actual conditions of different users.
