Claims (7)

  1. A measurement step (S10) for measuring the user's foot size and weight and taking a footprint; and After the above measurement step (S10), a professional podiatrist checks the footprint to determine and decide the user's foot shape in a shape confirmation step (S20); and A selection step (S30) for selecting a health foot insole by combining the foot size and weight measured in the measurement step (S10) and the foot shape determined in the shape verification step (S20), wherein the user's foot size is classified into 8 types, the user's weight is classified into 5 types, and the user's foot shape is classified into 3 types, and one type is combined from each to select a corresponding type from among a total of 120 types; and The manufacturing and providing step (S40) includes manufacturing the health foot insole in the type selected in the selection step (S30) and providing it to the user in a customized manner. The health foot insole selected in the above selection step (S30) comprises: an outer shell (10) formed to correspond to the user's foot size; a foot insole (20) coupled to the rear of the lower surface of the outer shell (10) and formed to protrude in a curved shape on the upper surface for correcting the user's foot, and having a first arch groove (24) formed on the lower surface to be located below the first arch projection (22); and an under pin (30) coupled to the lower surface of the foot insole (20), having a second arch projection (32) formed on the upper surface to correspond to the first arch groove (24) and having a horizontal lower surface, wherein one of 120 types is selected. A method for manufacturing a health foot insole characterized by the above-mentioned health foot insole being an orthotic that is customized for the user, standardizes strength and size, and is fixed inside the shoe to prevent movement.
  2. In paragraph 1, The 120 types of the above selection step (S30) are Select one of eight types classified by the user's foot size into 200 to 205mm, 210 to 215mm, 220 to 225mm, 230 to 235mm, 240 to 245mm, 250 to 255mm, 260 to 265mm, and 270 to 280mm, and Select one of five types classified by the user's body weight as 30 kg or less, 31 to 45 kg, 46 to 60 kg, 61 to 75 kg, or 76 kg or more, and A method for manufacturing a health foot insole characterized by selecting and combining one of three types of the user's foot shape classified as flat foot type, flexible flat foot type, rigid flat foot type, flexible high-foot type, rigid high-foot type, and high-foot type.
  3. In paragraph 2, The above-mentioned flat foot type is a case where the sole of the foot is flat without an arch, and The above flexible flat foot type is a case where the arch is deformed and the foot becomes flat due to acquired factors, and The above rigid flat foot type is a case where the foot is congenitally flat without an arch, and The above-mentioned high-footed foot is a case where the arch is excessively raised, causing the instep to rise high, and The above flexible high-footed foot type is a case where the instep lowers when walking and rises when standing still, and A method for manufacturing a health foot insole characterized by the above-mentioned rigid pes cavus being a foot in which the instep rises excessively and hardens during walking, causing the instep to become immobile.
  4. A health foot insole characterized by being manufactured by the method for manufacturing a health foot insole described in any one of claims 1 to 3.

Description

Manufacturing Method for Health Foot Insole and Health Foot Insole The present invention relates to a method for manufacturing a health foot insole that supports the arch of the foot to enable foot correction, and to a health foot insole. By classifying foot sizes into eight types, classifying the strength of the foot insole that is attached to the lower part of the outer shell and supports the arch of the foot into three types according to the shape of the arch of the foot, and classifying the strength of the underpin that is attached to the lower part of the foot insole and supports the lower part of the foot insole into five types according to the user's body weight, it is possible to manufacture a customized product according to the user's foot size, foot shape, and body weight, thereby resolving imbalance in the sole of the foot and consequently correcting the body's balance. Since the size, shape, and form of feet vary from person to person depending on their occupation and environment, it is important to use custom-made orthotics that fit the feet. Generally, shoes such as dress shoes and athletic shoes are divided into an outsole that contacts the ground and an upper that connects to the edge of the outsole and covers the entire foot, excluding the instep and sole. The outsole is divided into a bottom sole and a midsole, and an insole that comes into actual contact with the sole of the foot is placed on the midsole, and the insole is positioned on the inner bottom surface of the shoe to cushion the rebound force from the ground when walking or running, thereby protecting the wearer's skeletal system including the sole of the foot. Recently, functional shoes and posture-correcting insoles are being used to promote health and correct posture. Among these, posture-correcting insoles are installed inside shoes and function to correct left-right imbalances in the body by supporting the user's heel at a certain height; they are manufactured in various thicknesses and shapes depending on the user's characteristics. However, while conventional posture-correcting insoles are designed to support the user's heel at a constant height, the support height varies depending on the user's foot shape, resulting in inconsistent corrective effects. Furthermore, since the angle of heel support is fixed, it can cause pain or increase fatigue during walking if the user's foot is not of a normal shape (such as flat feet). Therefore, a structure for a custom-fit insole capable of adapting to the user's foot shape is required. As an example of prior art regarding a system for manufacturing customized insoles, Korean Registered Patent No. 10-2103332 relates to a smart insole automatic manufacturing system having a corrective treatment function capable of manufacturing an insole having a structure suitable for correction while diagnosing abnormalities in the foot based on 3D scan data. The system includes: a foot scanner that scans both feet together using a laser scanner and an image acquisition means; a 3D scan data module that generates 3D scan data for both feet from data transmitted from the foot scanner; a 3D foot model module that generates 3D modules for both feet from the 3D scan data; a foot shape analysis diagnostic module that analyzes the structure of both feet from the generated 3D modules to diagnose the abnormal condition of each foot; and a corrective structure insole generation module that generates a corrective insole structure for correcting each foot based on the diagnosis results of the foot shape analysis diagnostic module. However, the above-mentioned conventional technology requires the essential use of a module capable of measuring 3D scan data, which leads to increased manufacturing costs due to such a 3D scan data module, and while it is manufactured precisely, it has the problem of taking a long time to manufacture.

FIG. 2 is an exploded schematic diagram showing a health foot insole according to a preferred embodiment of the present invention. FIG. 3 is a block diagram schematically illustrating a method for manufacturing a health foot insole according to a preferred embodiment of the present invention.
