Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a floating structure is used to absorb misalignment and improve connection reliability, then connection reliability is improved, but the connector size increases
Solution Approach 1:
The shielding member is positioned to surround the insulator and contact, with its inner surface nested close to the insulator. This nesting arrangement allows the floating structure to absorb misalignment while minimizing the overall connector volume by efficiently utilizing space through layered component arrangement.
Solution Approach 2:
The shielding member extends in the width direction beyond the insulator, utilizing the lateral dimension to provide shielding coverage without increasing the length in the fitting direction. This dimensional optimization allows the floating structure to function while keeping the connector compact in the primary insertion direction.
2Reliability
If the transmission path is shortened to improve signal transmission, then signal transmission is improved, but noise resistance decreases
Solution Approach 1:
The shielding member acts as an intermediary between the contact and the external environment, surrounding the insulator and contact to block noise while allowing the transmission path to remain short. This intermediary shielding structure provides noise resistance without requiring an extended transmission path.
3Object-affected harmful factors
If shielding members are added to reduce electrical interference, then noise resistance is improved, but device complexity increases
Solution Approach 1:
The shielding member simultaneously serves multiple functions: it shields against electrical interference, provides structural support for the floating structure, and defines the lateral boundaries of the connector. This multi-functionality reduces device complexity by consolidating multiple components into a single integrated element.
Solution Approach 2:
The shielding member is integrated with the insulator and contact assembly, merging the shielding function with the structural support function. This consolidation reduces the number of separate components and simplifies the overall connector structure while maintaining effective electrical interference protection.
