Research on Coupling Design Problem Based on Extension Method
ZHU Ming

Abstract: Conceptual design, under the guidance of axiomatic design, will inevitably encounter the coupling design
problem. So a transforming bridge in extension theory was introduced to clear up the coupling problem. Decoupling
method of extension theory was proposed after analysing relationship between coupling problem of axiomatic design and
opposite problem of extension theory. The formal description was made on coupled problem which was confirmed by the
design matrix .Hereby decoupling process of axiomatic design based on the conversion bridge was constructed. An
example of vibration and wear of the ring frame spinning machine verifies the validity and feasibility of the method.
Key words: Axiomatic design; coupling design; transforming bridge; coexistence function
