Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible printed circuit board is used to collect temperature information, then temperature monitoring is achieved, but voltage information cannot be collected simultaneously
Solution Approach 1:
The patent combines temperature collecting wiring and voltage collecting wiring on the same flexible circuit board, merging previously separate monitoring functions into a single integrated structure. This allows both temperature and voltage information to be collected simultaneously through the same flexible circuit board connecting the battery terminal to the monitoring circuit.
2Adaptability or versatility
If separate components are used for temperature and voltage collection, then each function is performed, but device complexity increases
Solution Approach 1:
The flexible circuit board integrates both temperature collecting wiring and voltage collecting wiring into a single component, eliminating the need for separate connection structures. This merging approach maintains full monitoring capability while reducing overall device complexity by consolidating multiple functions into one integrated board.
Solution Approach 2:
The flexible circuit board is designed to perform multiple functions simultaneously: it serves as both a temperature sensing conduit and a voltage measurement pathway. By making the circuit board universal for both monitoring tasks, the patent avoids the complexity of separate dedicated components while maintaining both monitoring capabilities.
