Industrial Design Methods for Modularization and Pedigree Comprehensive Application in Rail Transit Passenger Vehicles

Abstract

Objective To address the difficulties faced in the industrial design of rail transit passenger vehicles, it is necessary to integrate innovative industrial design thinking and concepts to establish a comprehensive method for modular and pedigree applications in rail transit passenger vehicle design. Method First, a modularization analysis of passenger vehicle design components is conducted, dividing the compartment into fixed, optional, and custom modules, and categorizing the exterior into color and shape modules. Then, a pedigree analysis of passenger vehicle design contents is performed, establishing an industrial design pedigree from three dimensions: design requirements, evolutionary context, and product characteristics. Finally, based on passenger vehicle design characteristics, a passenger vehicle industrial design method for modularization and pedigree comprehensive applications is constructed, comprising three steps: sorting out modules based on design requirements, adjusting modules oriented by evolutionary context, and organizing modules based on product characteristics. Result & Conclusion The industrial design method is applied to a passenger vehicle design by a subsidiary manufacturer of CRRC (China Railway Rolling Stock Corporation). The design example verifies the feasibility of the constructed method. The modularization design allows for quick and flexible adjustments of design contents according to user needs, while pedigree design enhances design coherence and systematicity. Combining these approaches enables the completion of both exterior and interior passenger vehicle designs within a shorter design cycle, thereby improving design quality and reflecting brand features.
