A TRIZ-based systematic problem solving approach for heat treatment processes for screw manufacturing - A case study of oil mist purifying equipment

The screw manufacturing industry is an important industry for Taiwan. However, as the costs of processing pollutants increases, further study is required. This paper uses a TRIZ-based systematic approach and demonstrates a series of TRIZ tools for problem solving. In fact, TRIZ includes many tools and it is very useful as researchers can use diverse methods combining many tools to solve problems with different approaches. In this paper, we focus on a systematic approach consisting of some TRIZ tools such as problem definition, function analysis, cause and effect chain analysis, effects database along with Pugh's Matrix to solve the targeted problem and to evaluate the possible solutions. A TRIZ-based systematic approach for problem solving is demonstrated using a case study of suggestions to improve oil mist purifying equipment. The procedures proposed can be used as general problem solving procedures. Therefore, it contributes a feasible reference method for improving manufacturing process or equipment in screw industry or other industries.
