Conceptual Design Automation Of Mechatronics Product Based On Biologic Flow

The individuality, flexibility and intelligence have become important development direction of mechanical products with the development of science and technology. In the face of drastic international market competitions increasingly, and great attention in intellectual property rights, enterprises will lose market competitiveness if they simply rely on copying foreign products. Only through the product creativity, can enterprises solve the problem of surviving and developing fundamentally. As an important part of production design, conceptual design pays more attention to the integrity and creativity. In the creative design process of mechatronics system, the creation of design schemes is in a higher creative level in conceptual design. Conceptual design automation is the foundation of fast innovation methodology. Fast implementation and join of principle innovation and structure innovation is the key of conceptual design automation. Based on Biologic flow and Principle of Decomposition and Reconstitution of Function Surface the technology of model building, the automation mapping between Function and Structure.Give a summarization of present conceptual design of common products and mechatronics, point out the key of conceptual design of mechatronics system. It is pointed that the research on the design essence, the automation and integration of conceptual design process is the target to conceptual design research and it is the base for fast innovation methodology. The fast implementation and join of principle innovation and structure innovation is the key of them.The main contents of this paper are organized as:From the viewpoint of design methodology, based on the Principle of Decomposition and Reconstitution of Function Surface,Generalized Location Principle,LORD,Biologic flow Principle and Energy Chain Principle, "Information Chain Principle" and "The Design Automation of Mechatronics Product Based on Biologic Flow", which provide the uniform guidance for principle innovation and structure innovation.In the aspect of conceptual model building, Information-transforming Function Surface is proposed. With the double attributes of function and structure, it supports the definition of Function and the express of geometry information. It provides the operable models to express the abstract thinking of conceptual design logically and visually. According to energy and information transforming mode, the Function Surface is classified. The Location Code,Energy-transforming Code and Information-transforming Code of Function Surface are established.In order to support the fast express of conceptual design, Function Pattern is put forward. It improves the ability of Function and Surface describing. Some Function Patterns are defined according to the application of energy and information transforming. The Code of conceptual product and automation design process are established to unify the principle innovation and structure innovation.At last, the conceptual design automation system DARFAD and pre-D is introduced. With the example of water level controller, the feasibility and validity of the principles provided in this paper are proved. The research contents are summarized, and the questions that need research in future are put forward. A prospect about the next research contents is made out.
