Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional installation methods are used to connect and expand battery modules, then reliable electrical connections can be achieved, but the installation process becomes complex and time-consuming requiring numerous components
Solution Approach 1:
The guide coupling structure integrates alignment guidance and electrical connection functions into a single integrated component. The guide coupling protrusion and groove work together to simultaneously guide module positioning and establish electrical contact, eliminating the need for separate alignment fixtures and connection components, thus reducing installation complexity while maintaining connection reliability
Solution Approach 2:
The guide coupling structure acts as an intermediary mechanism between adjacent battery modules. It provides a standardized interface that mediates the connection process, enabling modules to be connected through a simple coupling action while ensuring proper alignment and electrical contact, thereby simplifying the overall installation procedure
2Stability of the object's composition
If conventional installation methods are used to connect and expand battery modules, then stable module arrangement can be achieved, but the installation time increases significantly
Solution Approach 1:
The guide coupling structure is pre-formed on the battery module housing during manufacturing. The protrusion and groove features are built-in, eliminating the need for on-site alignment operations or additional assembly steps, thus reducing installation time while ensuring stable and consistent module arrangement
3Reliability
If multiple components are used to connect battery modules, then reliable electrical connections can be established, but the cost increases due to high component quantity
Solution Approach 1:
The guide coupling structure combines multiple functions (alignment guidance, mechanical connection, and electrical connection) into a single integrated component. This eliminates the need for separate alignment pins, mechanical fasteners, and electrical connectors, thereby reducing component quantity and cost while maintaining reliable electrical connections through the integrated design
