Abstract:This paper presents a methodically structured design model for achieving a comprehensive improvement of product recyclability. The framework of this model consists of four design phases, integrating the prediction of product end-of-life strategy, the formation of modular structure, the selection of materials and fasteners, and the recyclability evaluation of design alternatives. The four phases are hierarchically organised in the body of the framework for a stepwise implementation, which are corresponding to the processes of generic engineering design at the stages of planning and task clarification, conceptual design and embodiment design. Fuzzy sets and graph theory are jointly applied as the basic techniques to formulate the methods for end-of-life strategy planning and structure modularisation. An air-conditioning system is used as an example to demonstrate the application of the proposed design model and its effectiveness in improving the recyclability of a product.
