Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual inspection is used to detect connector mounting failures, then detection capability is provided, but detection time increases and accuracy deteriorates
Solution Approach 1:
The patent replaces visual inspection (manual/mechanical observation) with an automated detection system that uses electrical signal transmission through the connector pins. The detection unit sends signals through the connection member to assess mounting quality electrically, eliminating the need for time-consuming visual examination while improving both speed and accuracy.
Solution Approach 2:
The patent introduces a connection member as an intermediary between the detection unit and the connector device. This connection member transmits detection signals through the connector pins to the circuit board, enabling indirect electrical measurement of mounting quality without requiring direct visual access to solder joints.
2Measurement precision
If X-ray equipment is used to detect connector mounting failures, then detection accuracy is improved, but equipment cost and setup time increase
Solution Approach 1:
The patent replaces expensive X-ray equipment with a cost-effective electrical detection system using simple connection members and detection units. The connection member can be easily replaced or reused, providing an economical alternative to costly imaging equipment while maintaining sufficient detection accuracy for mounting quality assessment.
Solution Approach 2:
The patent substitutes complex X-ray imaging equipment with a simple electrical measurement system. Instead of using radiation-based imaging, the system uses electrical signal transmission through the connector pins to detect mounting failures, dramatically reducing equipment complexity and cost while maintaining detection effectiveness.
3Ease of operation
If opening is drilled in connector device for visual inspection, then detection access is provided, but assembly complexity and cost increase
Solution Approach 1:
The patent extracts the detection function from the connector device itself by using a separate connection member that interfaces with the connector pins. Instead of modifying the connector device with openings, the detection system externally accesses the pins through the connection member, eliminating the need for structural modifications and additional assembly steps.
Solution Approach 2:
The connection member serves as an intermediary that provides detection access without requiring openings in the connector device. It interfaces with the existing connector pin structure and transmits detection signals, enabling inspection while maintaining the integrity and simplicity of the original connector device design.
4Ease of operation
If opening is provided for external inspection, then mounting state can be inspected, but connector device structure is compromised and cost increases
Solution Approach 1:
The patent extracts the inspection capability from the connector device structure itself. Instead of creating openings in the connector housing, the system uses a separate connection member that interfaces with the connector pins externally, preserving the complete integrity of the connector device while enabling effective inspection of mounting states.
