Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple conductive wires are coupled to the battery device in a conventional manufacturing process, then the battery device achieves proper electrical connectivity, but the manufacturing time increases significantly due to the extensive time required to fix the conductive wires
Solution Approach 1:
The patent combines multiple conductive wires and connection members into a single integrated support member structure. The support member includes multiple insertion grooves that simultaneously accommodate multiple connection members, which in turn hold multiple conductive wires. This merging of previously separate components into one unified structure allows all conductive wires to be fixed simultaneously during manufacturing, dramatically reducing the time required while maintaining proper electrical connectivity across all battery cells.
2Reliability
If multiple conductive wires are fixed in a conventional manufacturing process, then electrical connectivity is achieved, but the fixing stability is insufficient leading to potential short-circuits
Solution Approach 1:
The patent introduces connection members as intermediary components between the support member and the battery cell terminals. These connection members include connection portions that engage with battery cell terminals and insulation portions that prevent electrical contact between adjacent conductive wires. The support member further provides structural support and positioning through insertion grooves. This multi-layer intermediary structure ensures stable fixing of conductive wires while preventing short-circuits through insulation, thereby improving fixing stability and eliminating harmful short-circuit risks.
3Ease of manufacture
If conventional wire fixing structures are used, then manufacturing can proceed, but the assembly process is complex and time-consuming
Solution Approach 1:
The patent designs the support member with pre-formed insertion grooves that are specifically shaped to receive and position connection members and conductive wires. The connection members are also pre-configured with connection portions and insulation portions in specific arrangements. This preliminary preparation of the structural framework with built-in positioning features eliminates the need for complex assembly steps during manufacturing. Workers simply need to insert the pre-configured components into the predetermined grooves, dramatically simplifying the assembly process and improving manufacturing efficiency without sacrificing ease of manufacture.
