Axiomatic Design And Its Software Development

The design theory provides theoretic basis for the design activities and guides designers to get the good design that can reduce the developing time, improve the work efficiency and the performance of the product. The enterprise only mostly satisfying the custom needs can win in the competition.The design problem can be divided into four domains: the customer domain, the functional domain, the physical domain and process domain in axiomatic design. The two axioms are applied to evaluate the proposed design. Axiomatic design provides designers with the tool which can help designer to construct the design notion in the early of design. Axiomatic design generalizes the design process of the design frame that guides designers to make correct decision.The thesis discusses the design process based on axiomatic design. The designer goes through a process whereby he/she can zigzags between domains-functional, physical, completes the decomposition and judges the independence of function and the consistency of decomposition. If the design doesn't satisfy the function independence or the consistency of decomposition, contradictions are identified through analyzing the interactions between FRs and DPs. Then TRIZ is applied to solve contradictions to meet the design demands. This method combines the advantages of these two theories.The thesis introduces the development of the software for axiomatic design. The hierarchy, interface, operation and flow chart of software can be built by analyzing the software with Axiomatic-object oriented method. Then the models of the software are translated into the notion of object oriented and programmed with VC++ 6.0. This software can aid designers to make correct decision by building the decision-making environment. And it also can judge the independency and consistency of the decomposition automatically.The thesis discusses the analysis of valve with the developed software. The valve is decomposed into four levels form the view of conceptual design. All of the components of valve can be corresponding to each of leaf DPs. The structure of valve is reasonable. The design consequence of valve can be rebuilt by analyzing the full design matrix.
