| Abstract: |
| In view of that the classical TRIZ system is too large and the solving tool is difficult to master and apply due to lack of integration, the U-TRIZ theory is used to organically integrate the causal analysis model and the functional analysis model through material attributes with function as orientation and attribute as core, and then the constructed material- attribute-function-causal (SAFC) analysis model will effectively solve the above problems. The current application status and research improvement of SAFC analysis model in product conceptual design were analyzed. The solution methods of SAFC analysis model in contradiction type problem solving, displacement type problem solving and internal adjustment type problem solving were summarized. The basic composition, causal function chain drawing diagram and difference characteristic display table of SAFC analysis model were given and the general framework of U-TRIZ theory solution process was explained. SAFC model was a practical problem analysis tool evolved from physical field model to functional model. There were many kinds of problem-solving modes, which could effectively solve various problems. Finally, taking the conceptual design of smartphone as an example, the relevant methods of SAFC analysis model are validated. This study will provide a methodological guidance solution for mobile phone companies to find a breakthrough direction in product innovation and engineering problems. |
