Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate electrical cables are used to connect battery cells and external charging systems, then electrical connections can be established, but handling complexity increases and management becomes cumbersome
Solution Approach 1:
The patent merges the electrical connection function directly into the cover structure by integrating conductive tracks into the cover itself. This eliminates the need for separate cables and connection components, thereby reducing handling complexity while maintaining electrical connection functionality. The cover simultaneously serves as a protective enclosure and an electrical connection interface.
Solution Approach 2:
The cover is designed to be self-sufficient by incorporating the electrical tracks directly into its structure. The cover automatically provides both mechanical protection and electrical connectivity without requiring additional external cables or connection mechanisms, thereby simplifying the overall system and reducing handling complexity.
2Device complexity
If electrical tracks are integrated into the cover, then connection management is simplified, but insulation protection must be ensured
Solution Approach 1:
The patent applies different material properties to different regions of the cover. The cover is constructed with electrically insulating material in the regions where electrical tracks are integrated, while maintaining conductive properties where needed for connection. This localized differentiation ensures proper insulation protection while preserving electrical connectivity functionality.
Solution Approach 2:
The cover utilizes composite material construction combining insulating base material with integrated conductive tracks. This composite structure provides both the necessary electrical insulation for safety and the conductive pathways for electrical connections, thereby ensuring reliability while simplifying connection management.
3Adaptability or versatility
If cables are used for electrical connections, then flexibility in connection is provided, but the number of components increases
Solution Approach 1:
The patent combines multiple functions into the cover structure itself. The cover simultaneously provides mechanical protection, electrical connection pathways, and insulation, thereby eliminating the need for separate cables and connection components. This integration reduces the total number of components while maintaining the adaptability needed for electrical connections.
Solution Approach 2:
The cover is designed as a multi-functional component that serves as both a protective enclosure and an electrical connection interface. By making the cover universal in its functionality, the patent eliminates the need for separate specialized cables and connectors, thereby reducing component count while preserving connection flexibility.
