Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the groove portion between the memory unit and wireless transmission/reception unit is designed to be easily disconnected, then the manufacturing process becomes simpler, but the reliability of preventing IC tag removal deteriorates
Solution Approach 1:
The patent applies preliminary action by detecting wiring abnormalities before the IC tag can be successfully removed and reused. The detection circuit monitors the connection status of the groove portion and other wiring elements, and proactively identifies when disconnection occurs, preventing unauthorized reuse by detecting the abnormality before it compromises security
Solution Approach 2:
The patent implements feedback through the wiring abnormality detection circuit that continuously monitors the electrical connections within the IC tag. When the groove portion is disconnected or wiring is tampered with, the detection circuit provides immediate feedback about the abnormal connection status, enabling the system to respond to removal attempts
2Reliability
If the groove portion is made difficult to disconnect, then the reliability of preventing IC tag removal improves, but the manufacturing precision requirements increase
Solution Approach 1:
The patent replaces reliance on purely mechanical connection stability with an electrical detection system. Instead of depending solely on the mechanical strength of the groove portion connection, the system uses electrical wiring abnormality detection to monitor connection status, substituting mechanical security with electrical monitoring that can detect disconnection attempts
3Adaptability or versatility
If wireless IC tag authentication is implemented, then the ability to authenticate battery cells improves, but the risk of tag removal and reuse increases
Solution Approach 1:
The patent applies preliminary action by establishing wiring abnormality detection capabilities before authentication operations begin. The detection circuit is pre-configured to monitor connection integrity, and can detect removal attempts before they compromise the authentication system, enabling preventive security measures
Solution Approach 2:
The patent implements feedback by continuously monitoring wiring status and providing information about connection integrity. This feedback mechanism allows the authentication system to verify that the IC tag remains properly connected and has not been removed or tampered with, maintaining authentication security
