Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If connectors are designed for easy assembly, then ease of operation is improved, but connection stability deteriorates

Engineering Contradiction:
Improveease of assemblyVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements a feedback mechanism by detecting the connection state between connectors through electrical contact verification. The system provides real-time feedback to the user through display messages indicating whether connectors are properly connected, enabling users to adjust connections based on system feedback, thus resolving the contradiction between easy assembly and connection stability.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If connector connection is simplified, then ease of operation is improved, but connection precision deteriorates

Engineering Contradiction:
Improveconnection simplicityVSAvoidconnection precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent replaces mechanical verification methods with electrical detection methods. Instead of relying on mechanical switches or physical indicators to verify connection precision, the system uses electrical contact detection to automatically determine whether connectors are properly mated, thereby maintaining connection precision while simplifying the overall connection process.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If connection detection is added, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent achieves connection detection by utilizing existing electrical contact structures that serve dual purposes: both establishing electrical connectivity and enabling connection state detection. The same contact points used for normal electrical communication are also used to detect whether connectors are properly connected, eliminating the need for separate detection mechanisms and thereby improving reliability without significantly increasing device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
