Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a machine-readable code is always visible on the connection unit, then scanning and verification become easier, but the code may be detected in incorrect connection states leading to errors

Engineering Contradiction:
Improvescanning easeVSAvoidconnection verification accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The code element is made dynamically visible or invisible based on the connection state. In the unconnected state, the code is hidden; in the correctly connected state, the code becomes visible for scanning. This dynamic visibility ensures that the code is only detected when the connection is proper, resolving the contradiction between ease of scanning and verification accuracy.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If manual verification methods are used to check connection correctness, then equipment complexity is reduced, but time consumption and error rates increase

Engineering Contradiction:
Improveverification system complexityVSAvoidconnection verification efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The connection unit itself provides the verification function through the machine-readable code that becomes visible only when correctly connected. The system self-verifies the connection status without requiring external complex verification equipment, thus maintaining low device complexity while dramatically improving verification efficiency and reducing errors.

Inventive Principle:
Principle #25Self-service

3Difficulty of detecting and measuring

If the code is made visible from the outer side in all states, then detection becomes simpler, but the code may be detected in unconnected states causing verification errors

Engineering Contradiction:
Improvecode detection difficultyVSAvoidconnection state detection accuracy
Core Design Contradiction:
Difficulty of detecting and measuringVSMeasurement precision

Solution Approach 1:

The code element has different visibility properties in different connection states. In the unconnected state, the code is positioned or shielded to be undetectable from the outer side. In the correctly connected state, the code moves to or becomes visible from the outer side. This local quality change in visibility resolves the contradiction between detection simplicity and detection accuracy.

Inventive Principle:
Principle #3Local quality
