Abstract

The automotive industry faces a critical challenge in integrating sustainable design principles for the survival of future transportation. The use of biocomposite materials in automotive components requires a robust framework to balance sustainability objectives and product performance. The concurrent engineering approach was employed in this work, specifically for the conceptual design generation and selection of biocomposite headrests stay. Ideation processes employing Theory of Inventive Problem Solving (TRIZ) and Bio-inspired Design (BID), together with the best concept selection through Analytic Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), were executed. TRIZ assisted in problem modelling, as well conversion of specific problems to general problems. Then the contradiction matrix was used to find general solutions. BID facilitated bridging the gap in converting general solutions to specific solutions by providing potential solutions inspired by nature. Consequently, several design concepts were generated, with five alternatives being shortlisted. AHP and TOPSIS were then used in the establishment of criteria global weightages (CGW), performance evaluation for alternatives, ranking, and decision-making process. A2 is the best alternative based on its relative closeness to the ideal solution (C2+=0.7808) by demonstrating balanced performance, followed by A4 and A1 with (C4+=0.7385) and (C1+ =0.6619) respectively. Identical framework is applicable to other biocomposite automotive products with similar characteristics, where combining multiple tools in idea generation and selection can serve as a beneficial blueprint for future design processes, particularly within concurrent engineering and sustainable design practices. The future research directions are natural fiber and polymer selection.
