Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-voltage systems, existing technologies lack automatic detection of correct plug and socket insertion, relying on manual verification and expensive interlock contacts, which can lead to connection failures due to incorrect insertion.
Innovation Solution
A plug and socket device with a detection unit featuring a mechanically activated switching element, which can be visual or acoustic, to confirm correct insertion without the need for additional high-voltage interlock contacts, using components like crimping contacts, RFID transponders, or thin film circuits to ensure the plug is fully inserted and securely connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification of plug connection is used, then installation simplicity is maintained, but detection of correct positioning is unreliable
Solution Approach 1:
The plug connection system performs self-verification through the detection unit that automatically checks whether the plug is correctly positioned in the socket. The switching element is mechanically activated by the plug itself during insertion, eliminating the need for external verification tools or complex manual inspection procedures.
2Reliability
If expensive high-voltage interlock contacts are used, then correct connection monitoring is achieved, but cost increases
Solution Approach 1:
The invention replaces expensive high-voltage interlock contacts with a cost-effective detection unit that uses simple switching elements (such as conductive elements or printed circuit traces) to monitor plug positioning. These switching elements are inexpensive components that can be easily manufactured and integrated into the plug or socket design.
3Ease of operation
If detection unit is attached to both plug and socket, then interactive operation is achieved, but positioning precision requirements increase
Solution Approach 1:
The invention extracts the detection unit from the plug and places it solely in the socket (or vice versa). This eliminates the need for precise positioning between detection unit components on both plug and socket, as the detection unit remains stationary in the socket while the plug simply needs to make mechanical contact during normal insertion.
4Reliability
If housing lock is used, then prevention of unwanted detachment is achieved, but automatic electronic monitoring is still lacking
Solution Approach 1:
The detection unit provides automatic electronic feedback about the plug connection status. When the switching element is activated by correct plug insertion, the detection unit can trigger visual indicators (such as LEDs) or send signals to external monitoring systems, providing real-time feedback that confirms proper connection without requiring manual verification.
