Description

Insole design system

Technical Field

The present invention relates to insole design systems for designing insoles (shoeses spacers).

Background

Shoes originated from sandals worn by the royal of ancient egypt have been increasingly popularized all over the world while increasing profits.

Since the foot shape is different according to the race of a person, about 40 standard size models are prepared in mass production shoes, but it is difficult to cover individual deviations for various sizes of the foot shape, and a considerable number of people are troubled by the shoes grinding the feet.

Therefore, a method of manufacturing a shoe capable of easily changing the foot circumference size of a shoe having one foot length and one foot width is known (for example, see patent document 1).

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the drawings.

First, referring mainly to fig. 1 to 3, the structure of the insole design system 100 of the present embodiment will be specifically described.

Here, fig. 1 is a schematic explanatory diagram of the structure of an insole design system 100 according to an embodiment of the present invention, fig. 2 is a schematic perspective view of an insole 10 according to an embodiment of the present invention, and fig. 3 is a block diagram of the insole design system 100 according to an embodiment of the present invention.

The insole design system 100 has a database 101, a selection unit 102, a determination unit 103, and an insole three-dimensional data generation unit 104.

The configuration of the database 101, the selecting unit 102, the determining unit 103, the insole three-dimensional data generating unit 104, and the like is realized by the cloud server 22 such as a computer.

The customer takes a still image data or a video image data of the customer's foot 11 by using a smartphone 21 or the like equipped with a dedicated application software which can self-manage the foot file even after a trial period. The two-dimensional image data of the customer foot 11 is transmitted from the smartphone 21 to the cloud server 22, and is converted into three-dimensional customer foot data Dc by cloud service software. The input unit 105 is a unit that inputs such two-dimensional image data from the smartphone 21 to the selecting unit 102.

For example, the shoe manufacturer shapes the three-dimensional insole 10, which is a three-dimensional insole of a silicone material or the like an insole, filling the mismatched gap between the customer's foot 11 and the model foot, into the customer's demand (on-demand) by a 3D (three-dimensional) printer 23 based on the three-dimensional data of the insole corresponding to the three-dimensional data Dc of the customer's foot. The output unit 106 is a unit that outputs such insole three-dimensional data from the insole three-dimensional data generation unit 104 to the 3D printer 23.

Thus, the independent subscription service of insole 10 can be realized at a low price by using the IoT (Internet of Things) technology of cloud 20, completing an excellent business plan for providing low-price so-called semi-custom shoes.

Next, the structure of the insole design system 100 according to the present embodiment will be specifically described with reference mainly to fig. 3 to 8.

Here, fig. 4 is an explanatory view of the three-dimensional data Dc of the customer foot according to the embodiment of the present invention, and fig. 5 to 8 are schematic explanatory views (one to four) of the three-dimensional data Dm of the model foot according to the embodiment of the present invention.

In fig. 5 to 8, the model foot three-dimensional data Dm is shown by a solid line, and the customer foot three-dimensional data Dc for reference is shown by a one-dot chain line.

In fig. 5, the superimposed three-dimensional data Dc of the customer foot does not exceed the three-dimensional data Dm of the model foot. In fig. 6, the superimposed three-dimensional data Dc of the customer foot is out of the three-dimensional data Dm of the model foot.

In fig. 7, the superimposed customer foot three-dimensional data Dc does not exceed the model foot three-dimensional data Dm, and the distance δ and the three-dimensional space Σ are considerably small. In fig. 8, the superimposed customer foot three-dimensional data Dc does not exceed the model foot three-dimensional data Dm, but the distance δ and the three-dimensional space Σ are considerably large.

The database 101 is a database storing a plurality of three-dimensional data Dm of model pins.

The selecting unit 102 is a unit that superimposes the three-dimensional data Dc of the client foot on the three-dimensional data Dm of the model foot based on a rule for superimposing the three-dimensional data Dc of the client foot on the three-dimensional data Dm of the model foot so that the matching start point Pc of the instep portion in the three-dimensional data Dc of the client foot coincides with the matching start point Pm of the instep portion in the three-dimensional data Dm of the model foot, and selects the three-dimensional data Dm of the model foot, which does not exceed the superimposed three-dimensional data Dc of the client foot, from the three-dimensional data Dm of the model foot.

An example of the rule defined in the present invention is the rule of the present embodiment described above, in which the three-dimensional data Dc of the customer foot and the three-dimensional data Dm of the model foot are superimposed so that the matching start point Pc of the instep portion in the three-dimensional data Dc of the customer foot and the matching start point Pm of the instep portion in the three-dimensional data Dm of the model foot coincide with each other.

The determination unit 103 is a unit for determining one piece of model leg three-dimensional data Dm from the selected model leg three-dimensional data Dm based on the reference for determining the model leg three-dimensional data Dm in which the leg length λ is the minimum.

An example of the criterion defined in the present invention is the criterion of the present embodiment described above for determining the model foot three-dimensional data Dm in which the foot length λ is the minimum.

In the embodiment of the modified example, the reference defined in the present invention may be, for example, a reference for determining the model foot three-dimensional data Dm that has the smallest difference from the customer foot three-dimensional data Dc, which is related to the distance δ between the instep portion and the heel portion or the three-dimensional space Σ between the instep portion and the heel portion.

The insole three-dimensional data generating unit 104 is a unit that generates insole three-dimensional data corresponding to the customer foot three-dimensional data Dc, using the difference between the customer foot three-dimensional data Dc and the determined one model foot three-dimensional data Dm.

It is extremely effective to look at the difference between the customer foot three-dimensional data Dc and the determined one model foot three-dimensional data Dm. That is, the present inventors have noted that the matching between the customer's foot 11 and the footwear is important for the feeling of fitting, and the matching between the customer's foot 11 and the model foot is rather important for the feeling of fitting. Thus, the insole 10 which fills the difference between the three-dimensional data Dc of the customer foot 11 and the three-dimensional data Dm of the model foot of the standard model foot expected by the shoe manufacturer is molded, thereby reproducing the ideal feeling of fit expected by the shoe manufacturer.

Next, the operation of the insole design system 100 according to the present embodiment will be specifically described with reference mainly to fig. 3 to 8.

The operation of the insole design system 100 according to the present embodiment will be described, and an insole design method according to the present invention will be described.

(step of storing three-dimensional data of model foot)

For example, 40 model foot three-dimensional data Dm corresponding to about 40 standard-size models are prepared in a mass-produced shoe.

(step of selecting three-dimensional data of model foot)

The selecting unit 102 superimposes the three-dimensional data Dc of the client foot on the three-dimensional data Dm of the model foot based on a rule for superimposing the three-dimensional data Dc of the client foot on the three-dimensional data Dm of the model foot so that the matching start point Pc of the instep portion in the three-dimensional data Dc of the client foot coincides with the matching start point Pm of the instep portion in the three-dimensional data Dm of the model foot, and selects the three-dimensional data Dm of the model foot, which is not exceeded by the superimposed three-dimensional data Dc of the client foot, from the three-dimensional data Dm of the model foot.

Typically, as described above, the two-dimensional image data of the customer foot 11 is transmitted from the smartphone 21 to the cloud server 22, and converted into the customer foot three-dimensional data Dc.

However, it is also possible to provide an upload service of two-dimensional image data in which a store clerk in a physical store photographs the customer foot 11 by a dedicated photographing device or the like and transmits the two-dimensional image data of the customer foot 11 to the cloud server 22.

That is, insole design system 100 is effective not only in the B2C (Business-to-Consumer) industry, but also in the B2B (Business-to-Business) industry.

The conversion from the two-dimensional image data to the three-dimensional data Dc for the customer foot is realized by a known three-dimensional data shape restoration technique without requiring a large 3D measuring device. In order to improve the image recognition accuracy in such a three-dimensional data shape restoration technique, as shown in fig. 9 and 10, the customer may take an image of the customer's foot 11 while wearing a sock 12 printed with a plurality of marks M in patterns or colors.

Fig. 9 and 10 are schematic perspective views (one and the other) of a marker M according to an embodiment of the present invention.

The socks described above may also be prepared and distributed to the customer according to the size of the customer's foot 11. An instep mark Mi representing an instep portion and a heel mark Mh representing a heel portion, which correspond to the matching start point Pc of the instep portion, utilized for determining one model foot three-dimensional data Dm from the selected model foot three-dimensional data Dm, are desirably printed on the sock 12. Furthermore, a grid pattern for assisting the customer in photographing may be printed on the socks 12 so as to obtain accurate photographing data corresponding to the front, back, left, right, top and bottom views.

The customer foot three-dimensional data Dc may also be stored as IoT personal information, sold to shoe manufacturers who develop goods.

(determination of three-dimensional data of model foot)

The determination unit 103 determines one piece of model foot three-dimensional data Dm from the selected model foot three-dimensional data Dm based on the criterion for determining the model foot three-dimensional data Dm in which the foot length λ is the minimum.

In the embodiment of the modified example, the determination unit 103 may determine one piece of model foot three-dimensional data Dm from the selected model foot three-dimensional data Dm based on a criterion for determining the distance δ between the instep portion and the heel portion or the model foot three-dimensional data Dm having the smallest difference from the customer foot three-dimensional data Dc in the three-dimensional space Σ between the instep portion and the heel portion.

It is extremely effective to look at the difference from the customer foot three-dimensional data Dc, which is involved in the distance δ between the instep portion and the heel portion, or the three-dimensional space Σ between the instep portion and the heel portion. That is, the present inventors have noticed that the matching between the instep portion and the heel portion, which has been hardly thought so far, is important for the feeling of fitting the foot, through a customer questionnaire or the like. Thus, by shaping insole 10 to fill in the difference between the instep portion and the heel portion, the ideal fit presumed by the shoe manufacturer is reproduced.

The step of determining the three-dimensional data of the model foot may be performed after the step of selecting the three-dimensional data of the model foot as described above, or may be performed before the step of selecting the three-dimensional data of the model foot. For example, the plurality of model foot three-dimensional data Dm may be sequentially examined in the order of the length of the foot length λ until the model foot three-dimensional data Dm, beyond which the customer foot three-dimensional data Dc is overlapped, is found. That is, it is important to finally determine the most suitable one of the model foot three-dimensional data Dm based on the criterion that the superimposed customer foot three-dimensional data Dc does not exceed.

(insole three-dimensional data Generation step)

The insole three-dimensional data generating unit 104 generates insole three-dimensional data corresponding to the customer foot three-dimensional data Dc, using the difference between the customer foot three-dimensional data Dc and the determined one model foot three-dimensional data Dm.

Typically, as described above, the shoe manufacturer shapes the insole 10 into the customer's needs by a 3D printer based on insole three-dimensional data corresponding to the customer's foot three-dimensional data Dc.

However, along with the spread of 3D printers, a service for transmitting three-dimensional data of insoles, which enables customers to shape insoles 10 through the nearest printing shop, can also be provided.

In the formation of insole 10, the feeling of fit can be improved by using data obtained as a measurement result of a laser device that measures a three-dimensional space inside the shoe.

Of course, the insole 10 may be provided with a smart small IoT sensor such as a linear displacement sensor for measuring body temperature, exercise amount, working time, calorie consumption, energy consumption, and the like, in accordance with the request of the customer. The human body motion data obtained as the sensor measurement result is transmitted to an online memory such as the cloud server 22 via a mobile terminal device such as the smartphone 21 in real time, and is stored as IoT personal information. With the popularization of AI (Artificial Intelligence), an IoT health management system that can grasp the amount of exercise of the nation through analysis of the exercise statistics basic data collected automatically and provide a health maintenance recommendation service contributing to reduction of insurance risk can be realized.

The sole measurement pad may also be incorporated into insole 10 and the data obtained may be used as sole measurements to enable visualization of the sole. If the arch of the arch is formed by using the appropriate insole 10, the body weight can be directly applied to the sole of the foot, and thus the symptoms associated with the flat foot can be greatly improved.

It is also possible to incorporate an odor measuring instrument and a deodorizing material into insole 10 and use the obtained data as an odor measurement result to achieve a reduction in malodor.

The program of the invention according to the present invention is a program for executing, on a computer, the operations of all or part of the steps (or processes, actions, and the like) of the insole designing method according to the present invention, and is a program that operates in conjunction with the computer.

The storage medium of the invention according to the present invention is a storage medium for storing a program for executing all or part of the steps (or processes, actions, and the like) of the insole designing method according to the present invention, which is described above, in a computer, and the read program is a storage medium readable by the computer to be used in conjunction with the computer.

Note that the "partial step (or process, action, and the like)" means one or several steps among these plural steps.

The "operation of a step (or a process, an action, or the like)" means all or part of the operation of the step.

One mode of use of the program according to the present invention may be a mode in which the program is transmitted through a transmission medium such as a network, light, radio waves, or sound waves, and is read by a computer and operated in conjunction with the computer.

The storage medium includes a ROM (Read Only Memory) and the like.

The computer is not limited to pure hardware such as a CPU (Central Processing Unit), and may be firmware, an OS (Operating System), and a peripheral device.

Further, as described above, the configuration of the present invention can be implemented in software or hardware.
