Research On Technology Of Computer Aided Conceptual Design Innovation Oriented

Product innovation has become the one of the most important aspects which affects enterprises' strength. Being the kfey element of innovation, conceptual design has gained more and more recogonition. Thus computer aided conceptual design has also become a hot spot of the area. Although many work has been done in product information model and its opteration, few work is made for early stage of conceptual design.With the background of national hi-tech project(863) -Research on TechnologyComputer Aided Conceptual Design Innovation Oriented, product modelling and computing is discussed in this article. Specifically following contributions has been made:1. Definition of Component Feature Model2. Andvancing of a constraints driven layout creation methodology3. Inplementation of the above in a prototype system named CACDSIn the first part of the thesis the general contents of computer aieded conceptual design and its status quo is inrtoduced. Detailed definition of Component Feature Model(CFM) and its relative operations are described in chapter 2. In chapter 3 we invited ''Component Feature Space " as the key element in layout design, and a new constraints driven layout creation methodology, which is based on graph theory and human-computer cooperation, is discussed. Meanwhile an example of layout design of a vacuum is also introduced. Chapter 4 is mainly about the implementation of CFM and the creation methodology. In the last part the whole thesis is concluded, and some of the relevant directions for future work is discussed.
