Research on Product Design Strategy Based on “Divergence-Convergence”

Innovation is the core driving force of design. The purpose of this study is to propose a creative design strategy based on "divergenceconvergence", which aims to optimize the design behavior of designers or design teams in the product development phase. The proposed design strategy integrates the objectives tree method, function analysis method, finite structure method and morphological chart method in the design problem of desert tree-planting vehicle. Finally, the best solution is selected by fuzzy comprehensive evaluation. The results show that the proposed "divergence-convergence" design strategy provides a new design approach for designers, which is suitable for innovative design projects with high generality.
