Design method for assistive device and electronic system for assistive device design

Abstract

A design method of an assistive device and an electronic system of assistive device design are provided. The design method of the assistive device is adapted for electronic devices including a processor. The design method includes: obtaining a point cloud data of a limb part; determining a plurality of reference cross sections according to the point cloud data, wherein each of the reference crosssections is determined corresponding to bone protrusion feature points of the point cloud data, wherein the bone protrusion feature points are corresponding to the bony prominences of the limb parts respectively; establishing an initial digital model of the assistive device according to the reference cross sections; and performing a structural simulation analysis according to the initial digital model and design limitations to obtain a product digital model of the assistive device.

Description

technical field [0001] The invention relates to a product design and production technology, and in particular to a design method of an auxiliary device and an electronic system for designing the auxiliary device. Background technique [0002] When the limbs are injured, the movement will be affected. At this time, some equipment (such as plaster, crutches, protective gear, artificial limbs, etc.) is usually used for assistance. Such equipment is called assistive device. In terms of functionality, assistive devices may include mobility aids (e.g., wheelchairs, orthotic shoes, walking aids, crutches), assistive devices that assist limb functions (e.g., hand or leg prostheses, pencil holders, special spoons) ), life aids (safety alarm bells, ladder climbers), therapeutic or immobilizing aids (gypsum, back frame, waist support, knee pads, neck ring, pillow)...etc. The protective gear that is more common and often used by consumers is usually assistive gear related to physical a...

AI Technical Summary

Problems solved by technology

[0003] Generally speaking, assistive devices for immobilizing limbs are usually made of plaster, molds or related objects by experienced doctors or medical personnel, but such protective devices made of plaster will lead to very poor user experience

For example, because the plaster hardens after cooling, the user's skin will be very uncomfortable when it comes into contact with the plaster; high temperatures will be generated when making plaster-based protective gear; the material or structure cannot be changed to achieve customization...etc

On the other hand, auxiliary devices can also be produced in a fixed-size manner, but such auxiliary devices cannot provide perfect support, shape flexibility and comfort for the user's limbs

In addition, the materials and structures of uniformly produced assistive devices cannot be adjusted or changed according to the needs of users
