Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dedicated tools are used for unlocking, then secure locking is achieved, but rapid uncoupling without tools is prevented

Engineering Contradiction:
Improvesecure lockingVSAvoidrapid uncoupling without tools
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The connector assembly performs its own unlocking function through the elastic cantilever beams that automatically disengage from the sliding blocks when the plug connector is pulled away, eliminating the need for external tools or dedicated unlocking mechanisms

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The elastic cantilever beams provide dynamic locking that adapts to the coupling force applied, automatically engaging when pushed together and disengaging when pulled apart, enabling both secure locking and rapid release without tools

Inventive Principle:
Principle #15Dynamics

2Reliability

If complex locking mechanisms are used, then secure locking is achieved, but device complexity increases

Engineering Contradiction:
