Abstract Innovation in rail transit equipment involves inherent contradictions, such as safety versus cost, functional independence versus structural coupling, module universality versus diverse user demands, personalization versus low cost, and maintenance convenience versus structural compactness. To address these conflicts, several extenics-based methods were proposed, covering knowledge reuse of product and technological elements, knowledge graph construction and application, modular innovation, and technological innovation. The results show that extenics can effectively integrate product and technological elements and provide an approach to resolving various contradictory issues in modular and technological innovation of rail transit equipment. Moreover, the proposed methods significantly improve innovation efficiency.
