Description

 The present invention relates to a design device, and more specifically to a shoe-shaped design device.

 Shoes are an integral part of people's daily lives. There are various shoe styles, and new designs are released every season. The shape, size, and comfort of a shoe are affected by the shoe shape (a wooden shape used when processing shoes). The cost of shoes is also greatly influenced by the design of the shoe. At present, standard shoe molds are mostly hand-made designs and are therefore expensive. Also, the shoe-shaped design rules are based on research in 1964, and the new design software focuses on changing the shoe shape, not on the design.

 Existing shoe designs are based on planar wooden patterns and measurements around them, but these rules alone are not sufficient when designing. Thus, many shoe-type designers adopt existing shoe-types and avoid new shoe-type designs.

 With the aging of the population and obesity, more people are suffering from illnesses such as diabetes and arthritis, and many patients are suffering from shoes. A good shoe design can alleviate illnesses and complications related to the foot because most of the increased weight is borne by the foot. Currently, the majority of improvements to shoes concentrate on the design of the interior bottom surface and do not consider the shape of the shoe. Only when the overall shape of the foot is taken into account can the foot health be further improved. In addition, if the most appropriate shoe type (not only length and width) can be selected, foot disease can be improved. For foot health, a well-designed shoe type plays the most important role.

 An object of the present invention is to provide a shoe-type design apparatus that can solve problems such as the shoe-type design cost of existing technology being high and difficult to change.

 The invention adopted by the present invention to solve the technical problem is a shoe-type design device having a design surface that matches the outer surface of the shoe mold, wherein the design surface constitutes a first surface that constitutes the bottom surface of the shoe mold.

A shoe-shaped design device having a design parameter control point and a foot parameter control point.

 In the shoe-shaped design apparatus according to the present invention, the first control curve member includes a first control curve constituting an outer contour of the shoe shape, and a second control curve constituting an outer contour of the bottom of the wooden shape. A third control curve constituting a trajectory of the center of pressure at rest or during movement.

 In the shoe-shaped design apparatus according to the present invention, the second control curve member includes a first member unit that constitutes the rear side of the foot, a second member unit that constitutes the cross-section of the foot, And a third member unit constituting the tip.

 In the shoe-shaped design apparatus according to the present invention, the first member unit includes at least one control curve.

 In the shoe-shaped design apparatus according to the present invention, the second member unit includes a fourth control curve constituting a cross section of the heel, a fifth control curve constituting a cross section of the instep, and a sole arch. And a seventh control curve constituting the transverse cross section of the radial joint.

 In the shoe mold design apparatus according to the present invention, the third member unit includes an eighth control curve constituting a cross section of the toes, a ninth control curve representing the height of the toes, and a wooden pattern. And a tenth control curve for adjusting the smoothness of the tip of the wooden pattern.

 In the shoe-shaped design apparatus according to the present invention, the third member unit further includes a twelfth control curve located at the ankle and used for processing and adjustment.

 According to the shoe shape designing apparatus according to the present invention, the shoe shape designing device designs a three-dimensional shoe shape based on the auxiliary design of the computer and the model of the parameter. Provide new ways to meet your requirements. The device corresponds to the foot shape one by one by a plurality of control curves, and each control curve is configured by connecting some control points by adjusting the margin part, so that the control curves can be freely changed, By synthesizing the control curves, a three-dimensional geometric design surface that matches the outer surface of the shoe mold can be formed, and a three-dimensional entity can be formed. Further, the design of the shoe is changed by changing the design surface by changing the control curve. In addition, different control parameters of the control curve can be stored in the design table to record different styles and change the design. The shoe mold design apparatus (three-dimensional curved surface model or three-dimensional solid model) can make a shoe mold by an existing processing method. Whether you are a designer, manufacturer or practitioner, you can use the shoe-shaped design device and design your shoes based on your specific knowledge to improve the comfort of your shoes. can do. Since the control curve of the present invention corresponds to the foot shape one by one, it is possible to easily evaluate the comfort or foot health. The shoe-type design device is quite important for individual orders or large volume ordering enterprises, since a unique ordered shoe shape can only be realized if the cost can be reduced.

After the control curve is corrected, the shoe shape is finally corrected. A three-dimensional curved surface model or a three-dimensional solid model can be commercialized as a shoe mold by an existing processing method. In addition, control curves with different parameters can be used to automatically select the imitation design process using the design table (store design parameters for main design modifications) or to quickly select a design.

 The present invention improves the comfort of the shoe design and maintains the design function through the auxiliary design method of the computer.
