Abstract

TRIZ (Teoriya Resheniya Izobretatelskih Zadatch in Russian) refers to the "Theory of Inventive Problem Solving". Initially proposed by the former Soviet scientist Genrich Altshuller, TRIZ is a particularly remarkable technique to generate ideas for problem solving because it uses more systematic and concrete methodologies than other techniques and has a potential to produce feasible outcomes. The wide application of TRIZ, however, is limited due to the diversity and complexity of methodologies, which make it difficult to understand. The purpose of this study is to promote the understanding and utilization of TRIZ as an excellent tool to develop creativity in the age of 4th industry where intelligent talent is required. First, this study established the concept of TRIZ by learning and understanding various methodologies emerged in the development process. Based on ARIZ-85c (a complete version of ARIZ), this study explained su-field modeling, the butterfly diagram for resolving contradictions, the principle of physical contradictions elimination, algorithm for using the standards, and mapping the 76 standard solutions onto the 40 inventive principles. The above-mentioned theories were applied to specific cases in Chapter 4, which include 'single universal stamping tool', 'punching holes in thin-walled tubes', 'sealing ampoules with drugs', 'preventing rupture of pipes', and 'self –unloading barge'. The significance of this study is to provide a comprehensive understanding on TRIZ by synthesizing its relevant concepts and tools (problem solving techniques) and illustrating the case studies of applying TRIZ to solve specific problems in Chapter 4. However, despite the fact that 'algorithm for using the standards' and 'mapping the 76 standard solutions onto the 40 inventive principles' are incomplete, this study used them for the smooth process of TRIZ. As a result, this study has a limitation to provide the logical rationale because there exist some discrepancies between theories and the case studies of applying these theories. In the future, the ambiguity, incomprehensibility, and incompleteness of TRIZ should be improved so that TRIZ will be wildly used in various fields including technical science as an important topic of education for creativity development. Therefore, more studies and attempts should be made to enhance the general public's understanding and application of TRIZ. Future studies that modify and supplement Victor Fey's 'algorithm for using the standards' and Ellen Domb and John Terninko's 'mapping the 76 standard solutions onto the 40 inventive principles' will be a great help for the extensive application of TRIZ.
