Description

TECHNICAL FIELD [0001] The present invention relates to a design and manufacturing system for a foot orthodontic appliance,

[0001] The present invention relates to a system and method for designing and manufacturing leggings, and more particularly, to a system and method for designing and manufacturing leggings according to artificial intelligence based case based reasoning (CBR) And more particularly, to a system and method for designing and manufacturing a foot orthopedic device capable of efficiently manufacturing a 3D CAD file from a 3D virtual machine using the 3D printer.

In general, the footbaths support the weight, maintain the balance of the body and absorb the impact. Approximately 70% of the general people have deformed footbaths, have pain in the foot area, become deformed, People with symptoms are reported to account for about 20% of the total population, respectively.

As such, when the foot and foot shape is deformed, the upright joints of the legs, vertebrae, and neck are not balanced, and as a result, the health of the whole body, that is, the musculoskeletal system as well as the nervous system, respiratory system, endocrine system, And it causes various diseases.

In order to gradually transform the deformed hinoki to the normal hinoki form, a foot orthotic is made of a footstool support to fix or maintain the hinoki, and a rim surrounding the left and right sides of the foot and the heel.

Such a foot orthocenter is disclosed in U.S. Patent No. 4,686,994, and a method for manufacturing the foot orthocontractor is to acquire a foot image of a foot orthopedist, and a three-dimensional foot orthopedic orthopedic shoe capable of compensating for the deformed footwork Designing, molding and injection molding of footwear, standardizing footwear shoes in various categories according to footprint characteristics, prefabricating footwear footwear base by category, referring to the footsteps of customers provided at the time of customer order, There is disclosed a method of manufacturing a footwear tongue by partially trimming or attaching a material to a base in order to select a most suitable base among base tongue baseballs.

However, the footwear tongue and its manufacturing method thus manufactured require a large amount of cost and complicated equipment for the mold and injection molding, and in order to customize each individual, In order to select a footwear base and customize it, post-processing operations such as trimming or attaching must be followed manually.

Of course, in the market, there is a deal that sells footwear baseball shoes that are one of the standard size (for example, 410mm) of feet that are often used when purchasing footwear without the finishing work.

The footwear base of each category is based on an arbitrary standard foot type, and is often enlarged or reduced according to the foot size. Most of the footwear base types are designed in the same pattern, so various types of foot including a foot arch, The individual characteristics of the tennis base is almost impossible to be reflected in the base.

In this case, although the level of customization is increased in the case of the post-processing, there are some limitations or problems as follows.

First, in order to select a footwear base suitable for footbaths, a foot specialist who can analyze the foot is required. Secondly, the cutting work in post-processing is caused by the occurrence of dust etc., Third, the products supplied to the customers by the overhead waiting operation, along with the elapsed time of use, tend to be gradually discolored without maintaining the same quality as the base material of the footwear base, Which may cause deterioration of quality.

Fourth, pre-production of footwear base is also limited to providing tailor-made customization for all types of footsteps, since there are 20 categories to choose from and one is customized by post processing.

Most preferably, it is desirable to implement a one-to-one custom design and production system in which the knowledge of the footwear design is intelligent on the computer and the design and manufacture are interlocked and automated.

Korea Patent Publication No. 2006-0107102 Korean Patent No. 935,443 U.S. Patent No. 4,686,994

3 is a cross-sectional view taken along line AA of FIG. 2,
4 is a block diagram of an image sensing apparatus according to an embodiment of the present invention including an image sensing unit 100, a footprint input unit 200, a footwear tennis ball designing unit 300, a footwear tennis ball manufacturing unit 400, a control unit 500, and a customer management unit 600 A schematic diagram of a design and manufacturing system of a prosthetic ball,
5 is a flow chart for explaining a method of designing and manufacturing a foot orthodontic appliance according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may unnecessarily obscure the subject matter of the present invention. The same reference numerals will be used to denote the same components in the drawings, even if they are shown in different drawings.

First, as shown in Fig. 1, the foot image of the foot is varied according to the degree of deformation of the foot, for example, (a) is normal, (b) is flat, (c) It can be seen that various patterns are shown according to the state of being.

The shape, width, and pressure distribution of the foot of the footwall according to the deformation of the footbath were analyzed to provide information on the degree of deepening of the foot and the bracket, the degree of deformation of the foot and the toe, and the asymmetry of both feet.

In addition, as shown in FIG. 2, in consideration of the occupation and age of the customer provided from the customer, an imbalance of the body caused by the flat feet or braces and a footbath Can be formed.

The foot orthodontic appliance according to an embodiment of the present invention is designed such that the bottom surface is separated from the bottom surface of the shoe by a certain space so that the longitudinal center section of the foot orthodontic appliance is formed into a streamlined shape having a section shape similar to a crescent shape .

This is because when a foot weight is applied to a footbath, the footbath is composed of a material that causes bending deformation, so that the impact of the foot on the ground due to the weight is absorbed as the bending strain energy of the footbath, So that the bottom surface of the prosthetic foot is gradually abutted against the shoe floor and the shape is reduced to its original shape when the weight is removed.

In addition, the portion contacting the foot of the foot orthodontic appliance also has a streamlined shape so that the foot support 12 can be supported in close contact with the footed foot of the foot during walking.

Unlike the insole, which usually resembles the size of the sole, starting from the tip of the toe and reaching the heel, the footplate is usually placed in the middle of the fore foot starting from the center of the forehead to the heel It is made shorter than the insole.

That is, as the support of the footbaths of the footbaths and the footbaths of the footbaths are maximally adhered, the pressure distribution of the footbreads is extended over the entire top of the footbaths, and the deformed footbaths are normally guided to improve the balance of the body, It helps to eliminate disease factors caused by existing body imbalance.

In addition, the rim 14 can prevent the tread legs from being separated from the soles in the left, right, front and back directions during walking, and can help to mitigate the impact with the ground.

3, the foot orthodontic appliance includes a body 10 having a support 12 and a receiving container 11, and a body 10 having an inlet of the receiving container 11 And a lid portion 20 for opening and closing.

The storage container 11 of the body 10 may be recessed from the bottom of the body 10 to the inside of the body 10.

The storage container 11 provides a predetermined space form capable of inserting a functional product such as a direction (fragrance), an odor and a moisture removal, or a release of a skin irritation wave (for example, far-infrared rays, a therapeutic electromagnetic wave, an anion, etc.) And the lid part 20 is for opening and closing the inlet of the storage container 11 of the body part 10 and can be variously shaped like a box-shaped frame or a streamlined plate material bent with a predetermined curvature.

It is preferable that the lid part 20 is designed so that the size and the shape of the lid part 20 correspond to the storage container 11 when the body part 10 is designed.

Meanwhile, a predetermined fastening means (30) may be provided between the body (10) and the lid (20).

The through holes 21 are formed in the body 10 so as to confirm the size and the presence or absence of the contents of the contents in the storage container 11 of the body 10 and to make the skin irritation wave directly affect the skin of the sole of the user And the shape, size, number, etc. of the perforated holes can be variously applied.

The fastening means 30 includes a protrusion 31 of a predetermined shape integrally provided in the lid portion 20 and a protrusion 31 formed in the receiving container 11 of the trunk portion 10 in correspondence with the shape of the protrusion 31 And a groove-shaped groove 32 formed therein.

The trunk portion 10 and the lid portion 20 are configured to maximize individual fitting effects of a purchaser using a 3D printer. That is, it is possible to improve the calibrating and supplementing effect of the cervical spine, by increasing the individual fitting effect suited to the weight of the purchaser, the distribution of the load during walking, or the shape change of the cervical spine. It is advantageous in terms of performance and economy that the body 10 and the lid 20 are made of a 3D elastic material using a 3D printer.

 In order to change physical properties and chemical characteristics of the body 10 and the lid 20, it is necessary to change the type of footwear made of a polymer material, And adjusting the bending strength and elasticity according to the adjustment of the density (infill percentage).

For example, the internal packing density can be changed by considering the pressure distribution and weight of the door.

In addition, the footwear tent itself can be printed by using a 3D printer to form a ventilation structure, so that the air circulating through the shoe can remove the humidity in the shoe which may be caused by the occurrence of athlete's foot and the like.

In the case where the foot orthodontic appliance provided to the customer is required to be modified, the conventional foot orthodontic base is generally subjected to a separate cutting process or an additional process. According to an embodiment of the present invention, , The design can be partially modified, and a highly sophisticated design can be achieved by the expert's reinforcement of the result of the intelligent design.

4 and 5, a system and method for designing and manufacturing a foot orthodontic appliance according to an embodiment of the present invention will be described in detail.

FIG. 4 is a block diagram of a system for designing and manufacturing a foot orthodontic appliance according to an embodiment of the present invention, and FIG. 5 is a flowchart illustrating a method of designing and manufacturing a foot orthodontic appliance according to an embodiment of the present invention.

4 and 5, a footwear leggings design and manufacturing system 1 according to an embodiment of the present invention includes a footprint image sensing unit 100, a footprint input unit 200, a leggings tennis ball designing unit 300, A footwear tennis ball manufacturing unit 400, a control unit 500, and a customer management unit 600.

The footwear image pickup unit 100 includes a digital scanner for photographing the foot of a purchaser and a digital camera for scanning the footwear or a digital camera for filing the footwear, A foot scanner for digitally scanning and measuring a subject, and a digital scanner capable of three-dimensionally scanning a model of a foot shape or a foot shape of a foot shape.

Further, the footprint image pickup unit 100 may be a device for the customer to pick up his or her footprint image and transmit the captured footprint image digital data file to the footwear supplier by email or the Internet.

Meanwhile, the footprint image sensing unit 100 may be configured to measure foot pressure, which can generate digital footsteps by receiving pressure signals of a foot part obtained from a foot pressure measuring device installed in a customer's shoes through a wired / wireless communication network And a 3D scanning device that scans the entire shape of the foot three-dimensionally may be used as another footfall image pickup unit 100 so that the footwear form of the purchaser can be grasped more accurately.

That is, the footprint image sensing unit 100 acquires two-dimensional footprint image data or three-dimensional footprint image data (S100).

The footprint input unit 200 receives the two-dimensional footprint image data or three-dimensional foot shape image data from the footprint image sensing unit 100 and stores the footprint image data in the footprint image file DB 215 (S200) The data serves as a basic information for generating a 3D CAD shape model file of a customized foot orthotics desired to be designed and manufactured.

If a footer image file exists via email, the Internet, or the like, the user may directly input the file, or may have a user interface through which the data file is uploaded directly by the designer of the foot corrector.

The footprint input UI unit 210 may input the data in a wired or wireless manner.

4, the intelligent designing unit 310, the 3D CAD system 300, and the intelligent designing unit 310 are connected to each other, And a CAD unit 350 including a CAD file DB 360 and a CAD file DB 365.

The intelligent designing unit 310 is configured to design the design logic of the foot orthodontic appliance according to the case based reasoning company of artificial intelligence. The feature designing unit 320, the similar case extracting unit 330, the similar case DB 335, (340).

The similar case DB 335 includes a plurality of standardized cases as the form of family contact, and each case includes a parameter for the feature part in the geometry of the foot, and 3D CAD shape model design parameters necessary for designing the foot corrector And non-geometric data related to deformation of the foot.

Examples of the electron feature parameters are p1: 13mm, p2: 45mm, p3: 32 degrees. The 3D CAD model design parameters required for the design of the foot prosthesis are as follows: foot length: 265 mm; maximum width of the forehead: 11 mm; heel width: And the like.

Examples of non-shape parameters related to the latter's foot deformations include the foot strain parameters: flat foot, deformation grade: grade 3, Zone 1 pressure distribution: lower, Zone 2 pressure distribution: Value, and age group: 50-55, sex: male, occupation: worker, occupation period: 3 years, current disease: back pain.

The designing operation of the intelligent designing unit 310 is started by the feature extraction unit 320 according to an instruction from the control unit 500. [ That is, based on the case-based reasoning of the artificial intelligence, a feature is extracted from the footprint image input through the footprint input unit 200 of the footwear orderer (S310), and the similar case, (S320), the values of the parameters different from the extracted feature values of the orderer among the design parameters in the case are adapted to the values of the purchaser to modify the values of the parameters S330), and the result is transmitted to the 3D CAD system 360 so as to generate a 3D CAD shape model of the new foot orthocenter (S370).

In step S370, if it is necessary to provide information on the generated footwear treadmill CAD shape information, the modified feature shape design parameters, and other customers' occupations, weights, etc., The 3D CAD system 360 receives the value of the new design parameter inputted through the wired / wireless communication through the remote design support unit 370, And a step of generating a new CAD shape model of the CAD model.

The degree of similarity determination, which compares the features extracted from the inputted similar case extracting unit 330 with the cases stored in the similar case DB 335 one by one, indexes the features and indexes the values And indexes are sequentially compared on a case-by-case basis, so that the case in which the index values are most similar is judged to have the highest degree of similarity.

In addition, as the matching index, non-shaped data related to the foot deformations, such as pain or disease site, occupation, sex, and age, may be applied.

This is for designing different footwear tongues by assigning different values to the shape design parameters of the specific foot orthopedic tool from the additional indexes even when the footprint images are similar.

This is because there may be a difference in the 3D shape of the foot orthopedic considering the occupation. For example, in the case of manual worker and office worker, the 3D design of the footwear can be defined differently.

For reference, the modification of the design parameter information modified in the adaptation unit 340 shows that customization in the design stage is possible instead of attaching or trimming, which is customization of the footwear base. Also.

The 3D CAD system 360 may use general purpose CAD systems such as Unigraphics, CATIA, and Solid Works.

Using the system parameters, the control unit 500 calculates the design parameter values of the parametric modeled CAD file using the 3D CAD system 360 To generate a 3D model of a footwear 3D model of the purchaser and store it in the CAD file DB 365 as well.

For reference, the CAD systems provide so-called " parametric modeling " techniques that define a shape model as a parameter and its value, or establish a relationship between parameters. When a value of a design parameter corresponding to an independent variable is changed in a relational expression, The design parameters corresponding to the values are automatically changed.

Therefore, the CAD file DB 365 must have a shape model defined by a parametric model, and the design parameters and values thereof presented in the adaptation unit 340 are input as corresponding parameter values of the parametric model of the 3D CAD system 360 A new footwear leggings CAD shape model can be created. This execution command of the 3D CAD system 360 may be processed by the control unit 500. [

As the CAD shape model file that can be used when the 3D CAD system 360 creates a new footwear legged CAD shape model, a corresponding one of the similar case DB 335 can be prepared and used.

When the 3D CAD file is newly created according to the order of the purchaser, the control unit 500 adds the related case data to the similar case DB 335 or the CAD file DB 365, Can be continuously supplemented.

 As a result, the case base is enriched with time, and the similarity determination of the feature extraction unit 320 and the correction operation of the similar case extraction unit 224 are more efficiently performed. The increase in this experience information of the system corresponds to the intelligence that accompanies the increase of the expert's experience

The 3D shape file of the CAD unit 350 must be transferred to the slicing unit 410 in the STL file format in accordance with the control of the controller 500 in order to produce the 3D CAD data The model file is stored in a pre-STL file by the 3D CAD system 360, or the stored file is converted into an STL file, and the slicing of the model is performed in the slicing unit 410.

The control unit 500 transmits the STL file to the slicing unit 410 in step S380 and transmits the printing condition data FDM method according to the type of the 3D printer unit 450 required for slicing in the execution of the slicing unit 410 (Eg, supporter setting, print material, extruder temperature, layer thickness, internal fill density, nozzle feed rate, rapid feed rate, base platform temperature, etc.) (S400), a G code file and an .x3g file required by the 3D printer can be generated.

 Meanwhile, the control unit 500 can transmit the generated .x3g file or the like to the silver slicing unit 410 via the 3D printer unit 450 (S500), and allows the 3D printer unit 450 to perform the production (S600).

For reference, Replicator G, Slic 3r, Kisslicer, etc. can be used as the general-purpose SW used as the slicing unit 410.

The printing condition values to be input at the time of execution of the slicing unit 410 are called from the printing condition value DB 413. If necessary, the remote manufacturing support unit 470 controls the slicing unit 410 in accordance with the control of the control unit 500 The G code file, which is the result of the slicing, is stored in the G code file DB 415, and the G code file is stored in the G code file DB 415 , And also generate .x3g files from G code and transmit them to 3D printers online.

In general, the computer on which the slicing unit 410 is mounted can be connected to the 3D printer unit 450 on-line.

The footwear input unit 200, footwear footwear designing unit 300, footwear footwear manufacturing unit 400 and control unit 500 can be mounted on the same computer together with the customer management unit 600, The control unit 500 can perform communication.
