Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate members are used for mechanical coupling and electrical connection between battery cells, then reliable connection is achieved, but assembly process becomes complicated and system size increases
Solution Approach 1:
The patent combines mechanical coupling members and electrical connection members into a single integrated connector assembly. Each connector includes both mechanical coupling protrusions and electrical contact terminals, eliminating the need for separate components and reducing assembly steps while maintaining reliable mechanical and electrical connections between battery cells.
Solution Approach 2:
The connector design serves multiple functions simultaneously: mechanical coupling, electrical connection, and alignment guidance. The integrated structure performs mechanical support, electrical current transmission, and positioning functions in a single component, reducing system complexity while achieving reliable connections.
2Reliability
If multiple separate members are used for mechanical coupling and electrical connection, then stable connection is achieved, but total system size increases
Solution Approach 1:
By merging mechanical coupling and electrical connection functions into single integrated connectors, the patent reduces the total volume occupied by connection components. The combined structure eliminates gaps and redundant spaces between separate members, achieving compact integration while maintaining stable connections between battery cells.
3Reliability
If traditional connection methods with multiple members are used, then adequate electrical connection is achieved, but manufacturing and assembly become time-consuming
Solution Approach 1:
The integrated connector design allows for single-step installation that simultaneously establishes both mechanical coupling and electrical connection. This eliminates multiple assembly operations required by traditional separate members, significantly improving assembly speed while ensuring reliable electrical connection quality through the unified structure.
4Volume of stationary object
If compact battery module design is implemented, then spatial efficiency is improved, but connection and communication between modules becomes difficult
Solution Approach 1:
The connector design integrates multiple functions including mechanical coupling, electrical connection, and communication interface in a single compact component. This multi-functional integration enables compact battery module design while maintaining ease of connection through a unified interface that handles all connection types simultaneously.
