Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing high-voltage battery module connection technologies are used, then electrical connection between battery modules is achieved, but assembly complexity increases and alignment precision requirements increase
Solution Approach 1:
The patent combines multiple connection functions into a single integrated connecting element. This element includes opposing plug connections on both sides, integrated stop surfaces for alignment, and sealing elements, eliminating the need for separate alignment tools and multiple components, thus reducing assembly complexity while maintaining precise alignment
Solution Approach 2:
The connecting element acts as an intermediary component between two battery modules. It features a through-axis design with plug connections on both sides, allowing one module to connect to another module or component through this intermediate element, simplifying the overall connection system architecture
2Reliability
If multiple components and tools are used for connection, then reliable electrical connection is achieved, but assembly time and productivity decrease
Solution Approach 1:
The connection system is segmented into a modular connecting element that can be independently manufactured and assembled. This element contains all necessary components (plug connections, stop surfaces, seals) integrated into a single unit, allowing for standardized production and rapid assembly without requiring multiple separate components to be handled individually
Solution Approach 2:
The stop surfaces are pre-integrated into the connecting element at fixed positions along the through-axis. This preliminary positioning feature ensures that when the connecting element is inserted, alignment is automatically established without requiring external alignment tools or procedures during the assembly process, thereby increasing assembly speed while maintaining reliability
