TRIZ is one of the most famous tools for creative problem solving. However, it is said that TRIZ is complicated and difficult to understand and apply to solve problems. In order to resolve these difficulties, this paper presents S-ARIZ, a simplified ARIZ(the algorithm for inventive problem solving). S-ARIZ revised ARIZ-85C on two ways. First, cause and effect analysis is used to define core technical contradictions and control parameters for the physical contradictions. Second, we add 5 inventive principles which revised SIT(systematic inventive thinking) partially to IFR-1 definition (Step 3-2 of ARIZ-85C) to solve the intensified technical contradictions systematically and effectively. It is expect that S-ARIZ can contribute to the rapid spread of TRIZ.

Purpose: Storage furniture in a laboratory where chemical experiments are conducted should satisfy both the chemical reactivity and stability required in the experimental environment, commonality with general households, and economic feasibility for the mass production system. Therefore, the development of storage furniture used in the laboratory should be done quickly through a process verified by utilizing various ideas and using a method suitable for the special environment called the laboratory. This study deals with the process of developing materials for inner drawers of laboratory furniture that meet these requirements. Methods: TRIZ methodology and ARIZ-85C process were applied to satisfy the requirements arising from the product development process, ARIZ process was applied step by step to resolve the contradictions that occurred during the development process, and 40 invention principles and ideal solutions (Ideal Final Results: IFR) were derived through clear analysis of the problem to select materials suitable for the special environment of the laboratory. Results: This study focused on the selection of materials that meet the durability and chemical stability required in the special environment of laboratory furniture. Through this, various solutions were sought with the aim of reducing cost and increasing productivity, and the process of maximizing useful functions and minimizing irrational parts in use was focused on TRIZ's contradiction resolution method. As a result, we found a way to improve the performance and efficiency of laboratory furniture through the selection of optimized furniture materials and problem solving methods. Conclusion: In this study, a methodology for the development of efficient and safe laboratory furniture materials was found and verified. In the use of furniture products in a laboratory, corrosion or damage caused by chemical generators may occur, making it difficult to use as a product. As a result, a method to reduce cost and increase productivity while maintaining the durability and chemical stability of laboratory furniture was found, and by finding a solution to the two relationships between chemical safety and production efficiency in the process of selecting materials for optimized furniture materials, and applying the ARIZ development process, the effectiveness of the product development process in a special environment could be verified.
