Applying Axiomatic Design and TRIZ for Furniture Coating Process Improvement

This paper presents an approach based on Axiomatic design and TRIZ (Theory for Solving Inventive Problems) for furniture coating process improvement. Independence axiom of axiomatic design first examines the coupled problem due to interaction between manufacturing process design and function needs, and further analyzes the cause of the interaction between the function needs and converts it into the contradiction and conflict matrix. TRIZ is then applied to solve the design parameters in conflict or contradiction between functional requirements in the coupled problem. A real case of furniture coating process is investigated, and results show that the proposed approach can effectively improve coating defects.
