Integration of Axiomatic Design with Quality Function Deployment for Sustainable Modular Product Design

Abstract

Design is one of the most important stages in product development. Product design has experienced significant changes from concentrating on cost and performance to combining economic, environmental and societal considerations in design process. Sustainability is a new concept to balance economic, social and environmental aspects in product design. This research focuses on sustainable product design. The main challenging problem in the sustainable design is how the sustainable criteria can be used as quantitative metrics to evaluate products. This research integrates Axiomatic Design and Quality Function Deployment (QFD) concepts with Eco-design tools, such as Life cycle Assessment (LCA), to establish the quantitative metrics for sustainable product design. A novel wheelchair is designed as a case study in this research. Modularity is conducted to improve the wheelchair for the end of life cycle management
