[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a human body shape adaptation tool development device, a human body shape adaptation tool manufacturing method, and a recording medium for designing and manufacturing a tool adapted to a human body shape.

[0002]

2. Description of the Related Art At present, there are many tools used in contact with the human body. Examples of such tools include toothbrushes and eyecups used for eyewashing. Conventionally, these tools are often designed with emphasis on design as products.

[0003]

For example, in the case of a conventional toothbrush, the bristle shape of the brush portion is the same as that of the mouth portion (around the teeth and gums) even though the object to be brushed is the mouth portion. Referring to the details, there is no ergonomic toothbrush for biocompatibility. The reasons may be that the oral structure (around the teeth and gums) is complex and diverse, and that the design is advanced as described above. Thus, ergonomic designs are rarely used for tools that are used in contact with the human body. In recent years, CAD (Computer Ai)
ded Design), various tools have been designed. Design of tools taking into account the human body shape in detail has been carried out by using C data using three-dimensional human body shape measurement data (three-dimensional human body model).
There is no consistent example of using AD modeling technology.

[0004] The present invention has been made in view of the above points, and when designing and manufacturing a tool to be used in contact with the human body, a three-dimensional model adapted to the shape of the human body using CAD modeling technology. Apparatus for developing a human body shape adapting tool for generating a tool model, a method for manufacturing a human body shape adapting tool for producing a tool adapted to a human body shape, and generation or a human body shape of a 3D tool model adapted to a human body shape It is an object of the present invention to provide a recording medium in which a program for causing a computer to execute control relating to manufacturing of a tool adapted to the above is recorded.

SUMMARY OF THE INVENTION A human body shape adaptation tool development device of the present invention utilizes a CAD modeling technique to develop a tool to be used in contact with a human body, and is compatible with a three-dimensional human body model and the tool. The data of a predetermined three-dimensional basic model to be read is read, and a part of the shape of the three-dimensional human model is set as a transfer target, and is adapted to the human body shape based on the data of the three-dimensional transfer model transferred to the three-dimensional basic model. It is characterized in that a three-dimensional tool model of a tool having a shape that has been made is generated.

[0006] Instead of the three-dimensional basic model,
Data of a predetermined three-dimensional tool model corresponding to the tool is read, and a part of the shape of the three-dimensional human body model is transferred to the three-dimensional tool model as a transfer target, and has a shape adapted to the human body shape. A three-dimensional tool model may be generated. Further, in the human body shape adaptation tool development device of the present invention, the shape adapted to the human body shape is a shape including a shape that is the same as, similar to, or similar to the transfer site of the three-dimensional human body model.

In the human body shape adaptation tool development device of the present invention, cross-sectional data of a cross-section at a predetermined portion of the three-dimensional human body model is acquired, and a cross-sectional shape based on the cross-sectional data is converted into an axis perpendicular to the cross-sectional shape. It is preferable to generate a three-dimensional model composed of a three-dimensional shape formed by sweeping along the line, and use the three-dimensional model as a transfer target. It is desirable that the cross-sectional data is substantially perpendicular to the direction of use of the tool to be developed.

[0008] Further, the section data is obtained from a plurality of locations of the three-dimensional human body model corresponding to the part of the human body that comes into contact when operating the tool to be developed, and for each section shape based on each section data, It is further desirable to generate a three-dimensional model by averaging a plurality of three-dimensional shapes formed by sweeping along a vertical axis, and use the three-dimensional model as a transfer target. By doing so, even if the shape of the place where the tool is used is different in a part, it is possible to develop a tool having human body compatibility that is not biased to a specific location.

Further, in the human body shape adaptation tool development device of the present invention, a curve having a shape adapted to the human body shape is partially formed on the outer periphery based on the transferred human body shape curve at the transfer portion in the cross section of the transfer model. The human body contact portion of the three-dimensional tool model is deleted using a curved part having a shape adapted to the human body shape of the processed cross section, and the human body is added to the cross section of the three-dimensional tool model. A three-dimensional tool model including a curve adapted to the shape may be generated.

Further, in the human body shape adaptation tool development device of the present invention, the three-dimensional tool model adapted to the human body shape and the three-dimensional human body model are displayed on a display device connected to the human body shape adaptation tool development device. By displaying the transferred portion of the three-dimensional tool model on the transferred region of the three-dimensional human body model,
It is preferable to visualize the degree of contact of the three-dimensional tool model with the human body shape model. By doing so, the developer can check the degree of fitting of the generated three-dimensional tool model to the human body.

Further, in the human body shape adaptation tool development device of the present invention, the transfer portion of the three-dimensional tool model adapted to the human body shape is superimposed on the transfer region of the three-dimensional human body model. It is further desirable to form the three-dimensional tool model such that the unevenness of the contact portion of the three-dimensional tool model is minimized. By doing so, the generated three-dimensional tool model can be automatically fitted to the human body.

Next, the processing section model generating section 2f is based on the set conditions (in the example of FIG. 31, the fitting is performed on the lower side of the face) from the three-dimensional transfer model generated in step S15. Take the cross section and see Figure 32
A cutting curve (part 322 in FIG. 32) including a part of the transfer part curve 321 in the example shown in FIG. 32 is determined, and a processing cross-sectional model (part 331 in FIG. (See step S24). Next, the tool model forming unit 2i cuts the human body contact portion of the three-dimensional tool model (reference numeral 332 in FIG. 33) of the eyecup using the processing cross-sectional model generated in step S24, and conforms to the human body shape. A three-dimensional tool model of the eyecup is generated (step S25, see FIG. 34).

Finally, the fitting processing section 2j superimposes the contact portion (transfer portion) on the three-dimensional tool model of the eyecup generated in step S25 on a three-dimensional human body model (face surface model) again. It is displayed on the display device (see FIGS. 35 and 36). Further, a three-dimensional tool model of the eyecup is formed and fitted so that the unevenness of the superposed portion (the portion 371 in FIG. 37) of each model is minimized (step S2).
