Abstract: Function solving is the core part of product conceptual design. In the process of product design, due to the complexity of product technical requirements and user requirements, the functional solution is prone to deviation and uncertainty, which leads to the degradation of the whole design quality. Based on the above problems, the "Z" mapping transformation between functional and structure adjacent domains is used to decompose functions and determine the original understanding, and the correctness of Function solution is determined based on the functional independence axiom. Function analysis system technique is used to determine the functional correlation, establish the axiomatic design matrix, and determine the design type. Finally, the FAST model is used to characterize the results of the axiomatic design function solution and determine the design scheme. The roller machine tool is taken as an example to solve the problem, and a reasonable design result is obtained by axiomatic design and FAST layer by layer analysis, which verifies the validity of the model. The integrated solution model of axiomatic design and FAST combines the advantages of axiomatic design solution and FAST analysis to improve the design quality and accuracy.
