Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a signal corresponding to the ID code is input to the secondary battery and the output signal is received, then the secondary battery can be identified as a certified product, but the secondary battery may be mistakenly certified as genuine if an incorrect signal is received
Solution Approach 1:
The identification system is segmented into multiple independent verification components: magnetic pole arrangement verification, charging capability verification, and ID code verification. Each component checks a different aspect of battery authenticity, so that failure in one does not lead to false certification. The magnetic poles are segmented into specific N-S arrangements that correspond to different battery types, providing granular identification.
Solution Approach 2:
The wireless charging device acts as an intermediary between the battery and the verification system. It mediates the identification process by controlling the charging signal transmission and interpreting the battery's response. The intermediary verifies both the magnetic pole arrangement and the ID code before granting certification, preventing direct false certification through simple signal matching.
2Loss of information
If a specific signal is input to the secondary battery to determine ID, then the ID can be identified, but the system cannot distinguish between genuine and fake batteries with matching ID codes
Solution Approach 1:
The magnetic pole arrangement provides local quality differentiation within the battery structure. Specific N-S pole patterns are assigned to different battery types or authentication levels, creating localized magnetic signatures that cannot be easily replicated. This local magnetic characteristic serves as a physical fingerprint that complements the ID code verification.
Solution Approach 2:
The system merges multiple verification methods: magnetic pole arrangement detection, ID code verification, and charging response analysis. By combining these independent verification layers, the system recovers lost authentication information and achieves reliable distinction between genuine and fake batteries. The convergence of multiple verification signals provides robust authentication.
