Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple resistance change members are disposed at different portions in the battery pack for multi-point detection, then detection coverage is improved, but device complexity and cost increase due to requiring separate detection circuits for each member
Solution Approach 1:
Multiple resistance change members are electrically connected in series to form a single wire, allowing one detection circuit to monitor voltage changes across all members simultaneously. This merging approach maintains multi-point detection capability while eliminating the need for separate detection circuits at each location.
Solution Approach 2:
A single detection circuit is designed to universally monitor voltage changes across the entire wire containing multiple resistance change members. The circuit performs the same detection function for all members through the series connection, making the system more compact and cost-effective.
