Reverse Growth Design Theory-based Products, Technology Research And Development

Nowadays market requirements change more and more quickly, new product substitution appears day-by-day. In order to adapt to this situation, the redesign based on existing product prototype is the one of the best approaches for product innovation. The original requirement prototype of existing product, the base of redesign, is a key section of achieving a higher level of recovery. Based on the idea of product concept structure growth design, this paper mainly develops a research on product prototype recovery.The research situation of present domestic and overseas conceptual design and reverse design is investigated roundly. And it is pointed out that currently most researches of reverse engineering focus on 3D model reconstruction and rapid prototyping technology, however, few is about the theory or systematic study of product reverse design. According to this situation, the growth design theory based on product functional structure Decomposition and Reconstitution Principle and Generalized Positioning Principle is introduced, and a product recovery system supporting inventive design on this foundation is developed.Using ACIS, an advanced 3D modeling kernel, in this paper a product structure model based on functional face is built and a product reverse engineering system with many interfaces of ACIS is developed. Beginning from the existing product' s 3D modeling, the solid model of the product is built in this system or the file from third-party software' s is post processed. The growth design process is retrospect, the product is decomposed to a functional prototype made up of function units, then the recovery of the requirement prototype by the coupling between the function...
