Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable and flexible flat cable are used to connect battery pack cells to the signal acquisition board, then electrical connection is achieved, but the data transmission path becomes long which increases costs and reduces signal transmission quality
Solution Approach 1:
The patent combines the electrical connection functions directly at the battery pack cell level by integrating a welding terminal with soldering feet that weld directly to the cell terminals. This merging of connection functions eliminates the need for separate cables and flexible flat cables, thereby shortening the data transmission path while maintaining reliable electrical connection between the battery pack cells and the signal acquisition board.
2Reliability
If multiple connection components (cable, flexible flat cable, bus connectors) are used, then electrical connection is achieved, but device complexity and costs increase
Solution Approach 1:
The patent integrates multiple connection functions into a single welding terminal component. The terminal includes a pressing portion that mechanically connects to the battery pack cell, a welding portion that establishes electrical connection, and soldering feet that enable direct soldering to the cell terminals. This consolidation eliminates the need for separate cables, connectors, and flexible flat cables, thereby reducing device complexity and component count while maintaining reliable electrical connection.
Solution Approach 2:
The welding terminal serves multiple functions simultaneously: it provides mechanical support through the pressing portion, establishes electrical connection through the welding portion, and enables direct soldering through the soldering feet. This multi-functionality allows a single component to replace what would traditionally require multiple separate components, thereby reducing overall device complexity while maintaining connection reliability.
