Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual replacement of connectors is performed, then flexibility and simplicity are maintained, but labor intensity and error risk increase significantly
Solution Approach 1:
The patent replaces manual mechanical operations with an automated system that uses electromagnetic signals to detect cable connections. The device automatically identifies which cables are connected to which connectors by transmitting electromagnetic signals and measuring the resulting currents, eliminating the need for manual disconnection and reconnection while ensuring accurate correspondence between cables and connectors.
Solution Approach 2:
The replacement system performs self-verification by automatically detecting and confirming cable connections. The device measures electromagnetic signals to identify connected cables and verifies correct reconnection without requiring external testing, enabling the system to assist itself in ensuring connection accuracy during the replacement process.
2Productivity
If manual connector replacement is performed without automated verification, then device complexity is reduced, but time consumption and productivity loss increase
Solution Approach 1:
The patent enables continuous verification of cable connections during the replacement process. The electromagnetic signal transmission and measurement occur continuously or at key stages, allowing real-time detection of connection status without interrupting the replacement workflow, thus maintaining high productivity while ensuring accuracy.
Solution Approach 2:
The device introduces an intermediary measurement system that uses electromagnetic fields as a mediator between the cables and connectors. This non-contact measurement approach allows verification of connections without physically manipulating the cables, simplifying the overall system while enabling automated productivity enhancement.
3Measurement precision
If a separate test phase is implemented after connector replacement, then connection verification is improved, but total time consumption increases
Solution Approach 1:
The patent performs connection verification as a preliminary action during the replacement process itself, rather than as a separate post-replacement test phase. The electromagnetic measurement system verifies connections in real-time as cables are being reconnected, ensuring accuracy is built into the replacement process and eliminating the need for additional testing time.
Solution Approach 2:
The patent merges the replacement operation and verification function into a single integrated process. The same device that assists in identifying cable connections also performs the verification measurement, combining two previously separate functions (replacement and testing) into one unified system that achieves both goals simultaneously without time loss.
