COLLATION OF DESIGN KNOWLEDGE FOR SYSTEMATIC DESIGN FOR ADDITIVE MANUFACTURING AND TRIZ SYNERGISTIC APPLICATION

Systematic Design for Additive Manufacturing (DFAM) information should be provided throughout the product design and development lifecycle to enable designers to capture creative design solutions. Formalized design methods were more effective to ease DFAM utilization by designers. This study aims to collate DFAM knowledge in terms of design heuristics, principles and guidelines (HPGs) that can be synergized into a structured problem-solving technique such as Theory of Inventive Problem Solving (TRIZ) using Inventive principle (IPs). The approach is by mapping the HPGs through classical TRIZ 40 inventive principles based on four AM complexities: shape, functional, hierarchical and material. Six steps procedures were performed, and the mapping process leads to four knowledge clusters categorization within TRIZ and HPGs which include overlapped knowledge, unique knowledge, redefined knowledge and obscure knowledge. The mapping outcome reached 30% for overlapping knowledge, 22% of the 40IPs requires further analysis and appropriate to be redefined to suit AM applicability and 48% for obscure knowledge potential for future AM evolution. To demonstrate the applicability between the combination of TRIZ-DFAM, a conceptual case study was proposed involving a belt roller support to illustrate how AM users can creatively design innovative AM parts using the TRIZ-AM HPGs catalogue.
