TRIZ is innovative problem solving methodology. It can solve problems by systematical and convergent method, not by the existing divergent method like 'Brainstorming'. In this paper, TRIZ is used for reduction noise from gear in transmission. In order to reduce gear noise, design resources is derived first. According to the derived idea, level and function of system can be defined. After that, we suggest a way to reduce the noise from gear in transmission using 40 Principles and Substance-field analysis of TRIZ.
