The present invention relates to a wedge selection method of the insole by the pressure distribution of the sole. In particular, the present invention analyzes the pressure distribution of the sole measured in a postural / static or dynamic state by a Triple Pod System (TPS) scanner and applies it by the arch form or the metatarsal bone of the sole. Loss pressure and ankle insole to analyze the disease caused by pressure bias of the foot by grasping the pressure ratio of forefoot, middle and rear foot and inner and outer foot pressure ratio. A method for selecting wedges of an insole by the pressure distribution of the sole that allows the selection of wedges attached to the insole.

In general, the human foot is in contact with the ground at the time of standing up to support the weight of the human and at the same time serves to enable walking or exercise with an appropriate exercise. To this end, the entire sole of the foot is in contact with the ground to be distributed evenly to the human body weight, and most of the normal sole of the foot, except for the foot when the foot is in contact with the ground as a whole to enable a stable upright. In addition, in walking or running, the foot arch stretches like a spring to alleviate the impact applied to the foot, and allows the movement of the front end of the foot including the toes to be smooth and smooth, such as walking and running.

Human feet occupy most of the ergonomically normal foot having 4 to 6 degrees of external movement, 4 to 6 degrees of internal movement, and 8 to 12 degrees in total. In addition to human feet, there are various types of abnormal feet, which are usually caused by a supination in which the sole of the foot does not evenly contact the ground and the outside of the sole of the foot, and the inner and foot of the sole of the foot. Almost without this, the inner side of the sole has a shape which is divided into malformations referred to as hyperpronation and the like.

These abnormal types of feet, such as supinated, pronated and hyperpronated, are not only uncomfortable in strenuous movements such as running, but also in basics such as walking, as well as in maintaining uprightness. It can cause difficulties and pain.

Nevertheless, the existing shoes are not at the shape of the shoes to match the shape and structure of the individual feet, but at the level of fitting the feet to the shape of the shoes. As a result, it naturally goes on the feet, and the feet on the feet cause disharmony and imbalance in other parts of the body connected by one gang's athletic chain. In particular, because the feet, ankles, legs, knees, pelvis, waist, and upper body are intricately connected to the functional chain, it is not limited to foot problems when there is structural abnormality in the foot or when the functional wrong movement continues. It causes discomfort and imbalance in the legs, knees, pelvis, and spine, resulting in pain in each part of the body.

In order to overcome this problem, various researches and developments have been made on shoes that can help the movement of the foot and the orthodontic mechanism for straightening the foot. To make orthodontics for the correction of shoes or shoes that fit well, a mold is made of plaster bandage on the human foot to be applied, and based on this mold, an orthodontic appliance is made of synthetic resin of appropriate physical properties, or shoes He had made insoles for orthodontic footing.

However, the production of molds with plaster bandages and the production of orthodontic appliances or foot insoles based on the molds are time consuming and can only be made individually because they are manufactured for specific persons. In addition, it is not possible to mass-produce and it is not possible to use pre-made orthodontic or foot insoles for non-specific persons.

The insole for ski boots disclosed in Japanese Unexamined Patent Publication No. Hei 4-97701 is an insole formed by varying the thickness of the forefoot portion and the forefoot portion according to the pressure distribution of the foot. It is impossible to mass-produce because the pressure distribution of a specific person's foot must be measured individually, and the appropriate thickness is arithmetically calculated and then produced according to the appropriate insole thickness. Can not.

In addition, the "foot correction insole" disclosed in the Republic of Korea Patent Publication No. 0173096 (announced on January 15, 1999) is to be easily applied to the foot having problems such as external or internal and internal sessions. It adjusts the angle to the ground by applying various shear wedges and / or trailing wedges to the forefoot and the forefoot portion of the basic insole plate, respectively. In addition, by allowing the medial arch or wedge of the outer arch to be attached, the lower limb functions as many joint axes as possible and minimizes mechanical stress occurring in the lower limb. Helps to relieve pain and keep the musculoskeletal passions in place.

However, as described above, various wedges that can be attached to the basic insole plate have pelvic rotation such as waist level, pelvic inclination and horizontal rotation or inclination rotation, pelvic rotation before and after, inclination of the front and rear of the leg or knee, and metatarsal ground. This can be determined only by doctors or specialists with high expertise. Because of this, it takes a lot of time to put the wedge on the insole plate, and requires an expert with advanced knowledge.

An object of the present invention is to form the arch of the sole using the pressure distribution of the sole measured in a static and / or dynamic state by a TPS scanner including a plurality of pressure sensors that are constantly arranged without the knowledge of a doctor or specialist with expertise. (B) Wedges attached to the insole to analyze and compensate for diseases caused by pressure bias of the foot by analyzing the pressure exerted by the metatarsal bone and the pressure ratio of the forefoot, middle, and posterior foot and the inner and outer foot pressure. It is to provide a method for selecting wedges of insoles by the pressure distribution of the sole that enables the proper selection.

The wedge selection method of the insole by the pressure distribution of the sole according to the present invention, by using a TPS scanner (Triple Pod System scanner) including a plurality of pressure sensors arranged at regular intervals (postural / static) or dynamic ( a first step of repeatedly measuring two to six times the pressure exerted by the sole in a dynamic state; A second step of converting the pressure data formed by the sole measured by the pressure sensors of the TPS scanner into a digital signal and transmitting it to a personal computer; And after summing the pressure data transmitted from the pressure sensors of the TPS scanner and calculating an average value, the pressure applied by the arch shape or the metatarsal bone of the sole to the pressure of the sole of the foot, and the pressure ratio of the forefoot, middle foot, and rear foot The pressure ratio of the foot was compared and analyzed by the algorithm stored in the storage device of the personal computer to determine the types of wedges with different patterns, sizes, and thicknesses for each position of the insole plate, and the position of the insole plate to which the wedges are attached. Selecting a third step; characterized in that it comprises a.

In the embodiment, the pressure sensor 11 will be described as an example in which each of the 30 lines in the vertical and horizontal directions. Of course, the number can be increased to obtain more accurate measurement data.

The TPS control box 20 controls the operation of the TPS scanner 10 under the control of the personal computer 30 and simultaneously stores the pressure data of the analog signal transmitted through the handler 12 of the TPS scanner 10. The data is converted into pressure data of the digital signal which can be recognized by the 30, and transmitted to the personal computer 30.

The personal computer 30 refers to a conventional computer such as a desktop or a notebook, and the personal computer 30 stores various input means 40 such as a keyboard, a mouse, a scanner, etc., and various algorithms and measurement data. The apparatus 50, the monitor 60, the printer 70, etc. are connected.

The storage device 50 of the personal computer 30 has an arch shape or a metatarsal bone of the sole based on pressure data applied by the sole of the customer measured by the pressure sensor 11 constituting the TPS scanner 10. By analyzing the applied pressure, the pressure ratio of forefoot, middle foot, and rear foot, and the pressure ratio of inner and outer foot, the algorithm for selecting the type and attachment position of the wedge attached to the predetermined position of the insole plate for manufacturing the insole is stored. . Of course, the processor of the personal computer 30 is responsible for the execution thereof.

Here, the personal computer 30 analyzes the pressure distribution of the sole for manufacturing the insole as above based on the pressure data applied by the sole of the customer as shown in FIG. 4, but divides the sole into four as shown in FIG. In addition, the pressure ratio applied to the pressure sensor 11 of the TPS scanner 10 by each part of the sole divided into four parts can be measured.

The personal computer 30 is configured to measure the pressure applied to the pressure sensor 11 of the TPS scanner 10 once or repeatedly by the sole in the static mode and / or the dynamic mode. Use the data to determine the location and type of wedges attached to the insole plate for the insole manufacture or to determine the shape of the foot by averaging.

Wedges and the like. In addition, for example, the wedge is attached to a specific part of the insole plate to balance the soles to allow comfortable walking or doublet.

The personal computer 30, which collects and analyzes data for manufacturing insoles according to the characteristics of the soles of the customers, collects and analyzes data on the soles of the customers, various information obtained in this process, and the shape and soles of the feet obtained as a result. The pressure and the type of wedges attached to the insole plate constituting the insole are displayed on the monitor 60.

At this time, the pressure applied to the TPS scanner 10 by the sole displayed on the monitor 60 by the personal computer 30 may be displayed in a two-dimensional or three-dimensional image to facilitate visual confirmation of the result. have.

Furthermore, various measurement data obtained by the personal computer 30 or various information on the foot of the customer obtained by analyzing the same may be built into the storage device 50 as a database and output through the printer 70 as necessary. have.

Figure 3 shows the operation of the present invention to select the wedge of the insole by the pressure distribution of the sole, first input the customer's information to manufacture the insole mounted on the shoe to fit the specific customer's foot ( S31). This database is used as a database for information on the customer's foot, and is used as a material for manufacturing foot insoles for the treatment of the disease, the process of the disease, and the treatment of the disease.

After the customer information is input, the personal computer 30 is set to a measurement mode such as a static mode or a dynamic mode for measuring the pressure exerted by the sole using the TPS scanner 10 (S32) (S33) (S34). ).

Here, the static mode refers to measuring the pressure applied to each pressure sensor 11 by the soles while the customer stands on the TPS scanner 10, and the dynamic mode refers to the TPS scanner 10 It refers to measuring the pressure exerted on each pressure sensor 11 by the sole when passing over the step).

The personal computer 30, which measures the pressure applied to the TPS scanner 10 by the sole of the customer in the static mode and / or the dynamic mode, calculates an average value of the pressure values repeatedly measured in the static mode and the dynamic mode (S35). (S36).

Then, the personal computer 30 uses the algorithm stored in the storage device 50 to determine the pressure and the pressure ratio of the forefoot, the middle foot, the rear foot and the inner and outer foot pressures applied by the sole arch shape or the metatarsal bone of the customer.

Examples

First, based on the pressure data measured by the TPS scanner including a plurality of pressure sensors, the pressure applied by the sole arch shape or the metatarsal bone of the customer, the pressure ratio of the forefoot, middle foot, and rear foot, and the pressure ratio of the inner and outer foot are analyzed. Thus, the personal computer is equipped with software for selecting the type of wedge attached to a predetermined position of the insole plate and the attachment position for the manufacture of the insole for the customer only. Of course, it is obvious that a TPS scanner, a TPS control box, an input means such as a keyboard or a mouse, a monitor, and a printer must be electrically connected to a personal computer.

In the new inspection, the user first inputs customer information together with the working environment of the personal computer. The customer information includes the customer's name and shoe size. After inputting the customer information, if a measurement mode such as a static mode (postural / static test) or a dynamic test (dynamic test) is selected, an image as shown in FIG. 5 is displayed on the screen.

First of all, when the static mode is selected, the time bar at the bottom of the monitor is filled with red, and when the "Start" button is operated while the customer is on the TPS scanner, the time bar at the bottom of the monitor is filled with red and the distribution of foot pressure is Appears on the right side of the monitor.

Here, the foot pressure is displayed in blue on the less pressure side and red on the high side. In addition, the measurement values displayed on the right side of the monitor include the maximum pressure of the forefoot sensor, the maximum pressure of the rear foot sensor, the pressure ratio of the forefoot at the total pressure, the pressure ratio of the back foot at the total pressure, and the shape of the arch ( H high / high / M high / normal / M flat / flat, etc.), average pressure per sensor, total number of inductive sensors, length from heel to toe, length from heel to toe.

Next, when the dynamic mode is selected, operate the "Start" button at the bottom of the monitor and allow the customer to step on the TPS scanner with their left and right foot. When the customer steps on the TPS scanner, press the Stop button to check the result without having to wait until the time bar at the bottom of the monitor is full red, then press the RF button on the top of the monitor to rewind the screen, and then press the FF button. Observe the foot movement frame by frame, pressure and center of pressure (COP), and then press the average display button to check the foot pressure distribution in the dynamic mode using the measurements shown on the right side of the monitor.

The user then presses the Analyze button to obtain the type or location of the wedge attached to the insole plate for insole manufacture.

Here, in the dynamic mode, there is a multi scan mode, which is to execute the static mode 2 to 6 times to obtain more accurate data and results.

In other words, after running the static mode as many times as you want, after excluding the screen where you do not want the average analysis, press the analysis button on the screen that shows the best shape of COP or foot.

Then, after pressing the average analysis button, the user can press the report preview to check the shape of the foot by the average analysis, data, the type and location of the wedge attached to the insole plate for manufacturing the insole.

In addition, the present invention can facilitate visual analysis since the pressure applied by the sole measured by the TPS scanner is displayed in a three-dimensional image as shown in FIG. Furthermore, the present invention not only reduces / enlarges, moves, and rotates the 3D image, but also has various functions such as color change, light control, and line type selection.

Figure 8 shows the final result, the final result is to distinguish the type of foot type of P (regular foot), S type (feet), H type (flat feet), and as a result the medial arch and the outer arch and A metatarsal dome and the like are obtained according to the measurement results of the left and right feet.

FIG. 9 shows that the result measured as shown in FIG. 8 is displayed through a monitor or a printer.

FIG. 10 shows the measurement data for the previously measured foot and the measurement data for the currently measured foot on one screen so that the customer can compare each other. Of course, in this case, the comparison must be done separately from the static and dynamic modes.

11 is an example of a screen displaying the degree of force over time when the customer's foot is measured in the dynamic mode. The left side shows the left foot, the right side shows the right foot, and the symmetry of left and right can be compared. Here, the X-axis at the bottom left of the screen represents time, and the Y-axis represents force, and the size of the graph displayed on the screen can be arbitrarily adjusted by pressing the up and down arrows.

Accordingly, the present invention utilizes the pressure distribution of the sole of the foot, measured in a static and / or dynamic state by a TPS scanner including a plurality of pressure sensors that are constantly arranged, and the pressure and forefoot applied by the arch of the foot or the metatarsal bone, Analyze the pressure ratio of the middle foot and the rear foot and the pressure ratio of the inner and outer foot to analyze the disease caused by the pressure bias of the sole and to appropriately select the wedge attached to the insole to compensate for this. It is possible to manufacture an insole for a shoe that fits a user's feet without having to go through a doctor or expert with one's expertise.
