Abstract: To solve the problems of classification fuzzy and conflict complexity in productization innovation process,an extension method for conflict problem granularity classification and coordination was put forward.Through the element integrated operation of various technical requirements,the design ideas of technology innovation was cleared.The mechanisms of conflict problem stripping and conduction were established respectively with the granulation method,and  the multi-level graining model was built based on conflict problem solution.By using the axiomatic design theory,the structuring mapping model was established for fine-grained conflict problem,which would be taken as the problem coordination evaluation index.On this Basis,the multiple granularity levels of technological innovation flow were established.Furthermore,the technology innovation product programs were generated by setting up the dynamic regulatory mechanism of key transformation step size and conduction effects.The ambient mass spectrometry ion source was taken as an example to verify the effectiveness and feasibility of the proposed method.
