Applying TRIZ Theory to Enhance CDIO-Based Design Process for Improving Problem-Solving Skills of Technicians.

This paper presents the application of the Theory of Inventive Problem Solving (TRIZ), integrated with the CDIO (Conceive - Design - Implement - Operate) framework, to enhance the problem-solving skills of technicians and reduce losses in the manufacturing process. TRIZ is incorporated into the “Conceive” and “Design” stages of the CDIO approach to systematically develop problem analysis and solution design capabilities. In the “Conceive” stage, participants used the Fishbone Diagram to identify root causes and applied Altshuller’s 39 Engineering parameters to determine the technical contradictions. In the “Design” stage, these contradictions were addressed using TRIZ’s 40 Inventive Principles to derive innovative solutions, which were then employed to develop a machine inspection plan. The “Implement” stage involves the practical application of the inspection plan, while the “Operate” stage compares results before and after implementation. The findings indicated that integrating TRIZ with the CDIO framework enables technicians to systematically approach problems, design effective solutions, and significantly reduce production losses.
