Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector arrangements with RFID-enabled CPA members face signal leakage issues due to covered RFID tags, which can lead to inaccurate mating confirmation and potential accidental unmating.
Innovation Solution
A connector arrangement with a CPA member and a detection device featuring an electric circuit and a spring contact with a resilient member, allowing the electric circuit to be switched on and off, indicating the closed state of the CPA member through a transmission antenna and logic block, thereby confirming proper mating and preventing accidental unmating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an RFID tag is used to detect CPA member deployment, then mating confirmation capability is improved, but signal leakage occurs due to the tag being covered by electrically conductive material
Solution Approach 1:
The patent extracts the RFID tag from the covered position and places it on the exposed outer surface of the connector housing. This allows the RFID tag to be read wirelessly without being blocked by electrically conductive material, eliminating signal leakage while maintaining mating confirmation capability.
Solution Approach 2:
The patent introduces a reader device as an intermediary that wirelessly communicates with the RFID tag. This mediator enables detection of CPA member deployment status without physical contact or line-of-sight requirements, solving the signal leakage problem caused by conductive material coverage.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively addresses signal leakage issues by ensuring accurate mating confirmation and preventing accidental unmating, enhancing the reliability of electrical connections, especially in high-voltage applications.
Implementation Method 1
The resilient member is deflected by at least one of the connector and the mating connector when the CPA member is moved from the open state to the closed state
