Research on Top-Down Collaborative Product Design Method

This paper introduces a top-down collaborative design methodology rooted in the concept of initiating product development from a holistic perspective, encompassing overall scheme planning, layout design, and subsystem refinement, down to detailed component engineering. This approach transcends software platform constraints and harmoniously integrates with the R&D workflows prevalent across industries, especially in large-scale, interdisciplinary product development endeavors. The core of our proposal revolves around a skeleton model-based framework that encompasses the establishment of a collaborative platform, outlining a top-down collaborative design strategy, and facilitating parallel design efforts across departments. This ensures that product conception stems from a unified vision, with seamless intent communication and efficient multi-disciplinary labor division, ultimately culminating in a comprehensive digital prototype equipped with models suitable for advanced applications like finite element analysis and motion simulation, fostering innovation and efficiency in the entire design lifecycle.
