Research And Development Of Human Originated Product Reverse Engineering

Innovation drives human progress and human society development, which is not only the fundamental of design, but also the life fountain of modern product design. Generation after generation designers create many excellence products to improve human survival mode and people's quality of life. Development of Western developed countries in the field of industrial design proved that product reverse engineering approach is an effective way for technology progress of developing countries.The research situation of current domestic and oversea reverse technologies and theory fundamentals are investigated systematically, the importance of Innovation is emphasized based on reverse technologies. Human originated reverse engineering is put forward in this paper.Current research of reverse technology mostly focuses on 3D model reconstruction and rapid prototyping technology, few is about the theory or systematic study of product reverse design concept and human original requirement. Human originated reverse technology and theoretical framework is proposed in this paper to extend product structure and dynamic design thinking process.The aim of Human originated reverse is to obtain the functional prototype of product and reproduce the requirement prototype with absorbing the design methodology and key technology of the product. In this paper, the general model of design process is introduced and the type of functional surface is expanded based on Decomposition and Reconstitution Principle and Generalized Positioning Principle. The growth design theory is proposed and Human originated product reverse system supporting inventive design on this foundation is developed.Description and expression of the functional surface is realized on using the Object Oriented technology, also the expression of the functional part. And product reverse data structure model is built up based on functional surface. From the point of function and position, function mode is concluded from solid part which has the same function, which include execute mode, transmission mode, structure mode and motivity mode. Using ACIS, an advanced 3D modeling kernel, in this paper a product reverse system PRE-D is developed. Product reverse system framework and the key technology module is created, product rapid modeling and assembly module, product function prototype obtain module, product reverse solution module and product functional surface expansion module are included.Finally, the functions, module setting, technologies and running environment of system are expatiated. With examples of hand-lever press and washing machine, the recovery process of the product prototype and the product functional surface expansion are illustrated in details. The correctness and rationality of the theory research and implementation of technology is validated.
