Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a common connector is used for units with different signal line configurations, then connector versatility is improved, but assembly precision deteriorates due to uneven insertion forces
Solution Approach 1:
A bent signal line is introduced as an intermediary element connected to unused terminals. This bent signal line acts as a force distribution mediator that transmits and balances insertion forces across the connector, preventing uneven force distribution caused by missing signal lines in certain configurations.
Solution Approach 2:
The physical configuration of the signal line is changed by creating a bent shape with a fold part. This geometric parameter change allows the signal line to flex and distribute mechanical forces more evenly during connector insertion, compensating for the absence of signal lines in monochrome units while maintaining connector compatibility.
2Device complexity
If a common connector is used for units with different signal line configurations, then device complexity is reduced, but reliability deteriorates due to potential connection failures
Solution Approach 1:
The bent signal line serves as a mechanical intermediary that ensures uniform force distribution during connector insertion. This prevents diagonal insertion and ensures all connector terminals make proper contact, thereby maintaining connection reliability across different unit configurations.
Solution Approach 2:
The bent signal line is pre-configured to counteract the potential harmful effect of uneven insertion forces before connection failure can occur. By distributing forces evenly from the beginning of the insertion process, it prevents the development of diagonal insertion patterns that would lead to connection failures.
3Ease of manufacture
If a common connector is used for units with different signal line configurations, then ease of manufacture is improved, but productivity deteriorates due to reduced assembly efficiency
Solution Approach 1:
The bent signal line acts as a mechanical guide that directs insertion forces evenly across the connector. This prevents diagonal insertion and ensures proper alignment during assembly, significantly improving assembly efficiency and reducing manufacturing time.
Solution Approach 2:
The bent signal line creates a force equilibrium by distributing insertion forces evenly across all connector terminals. This equipotential force distribution eliminates the need for complex alignment procedures and enables faster, more efficient assembly operations.

AI summary
A connector module includes a connector having multiple connection terminals including: a first connection terminal to transmit a drive signal; and second connection terminals not used to transmit the drive signal; a transmission signal line connected to the first connection terminal to transmit the drive signal to the first connection terminal; and a bent signal line connected to the second connection terminals. The bent signal line has both ends connected to the second connection terminals; and a fold part between the both ends.
