Appling TRIZ Theory in Ship Overall EMC Design

Abstract

Same frequency interference between electronic equipment still cannot be wiped out, which leads electromagnetic compatibility (EMC) system engineers to the one and only way by making an EMC rule to manage and control all the equipment onboard. However, while the sensors are following the EMC rule in battle, the weapons’ maximal combat capability is usually not able to be attained. Therefore, EMC management and control widely used in today’s ship engineering design is actually a compromise. This paper presents an unconventional design method combining the TRIZ methodology into traditional EMC design methods. The proposed method used TRIZ tools such as function analysis, causal analysis, ideal solution analysis and resources analysis to make deep analysis of the same frequency interference problem on ship. The final solution is obtained through contradiction resolution theory, Su-Field analysis and 76 standard solutions in this paper. At the end, a few enlightening ideas are harvested for the engineering innovative design problem.
