Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional electrical connectors use traditional locking mechanisms, then connection strength is maintained, but assembly and disassembly time increases
Solution Approach 1:
The patent employs a rotating cap with torsion spring that enables dynamic locking and unlocking actions. The rotating cap can be quickly rotated to lock or unlock the connector, while the torsion spring provides the necessary dynamic force for quick operation. This dynamic mechanism allows rapid assembly and disassembly without compromising connection strength.
Solution Approach 2:
The torsion spring automatically returns the rotating cap to its initial position after rotation, providing self-service functionality. The inertial force generated during rotation automatically engages the locking blocks with the locking grooves, eliminating the need for additional manual operations to secure the connection.
2Productivity
If quick-release mechanisms are used, then assembly speed increases, but connection reliability decreases
Solution Approach 1:
The connector is segmented into multiple functional components: rotating cap, locking blocks, locking grooves, and torsion spring. Each component performs a specific function, and their coordinated interaction ensures both quick assembly and reliable connection. The segmentation allows for simplified individual parts that are easy to manufacture and assemble.
Solution Approach 2:
The torsion spring is pre-loaded to store elastic energy before the locking operation. This beforehand cushioning ensures that when the rotating cap is rotated, sufficient force is available to securely engage the locking blocks with the locking grooves, guaranteeing connection reliability while maintaining quick operation.
3Strength
If complex locking structures are used, then connection strength increases, but device complexity increases
Solution Approach 1:
Multiple functions are merged into the rotating cap structure: it serves as both the operating handle and the locking mechanism carrier. The locking blocks are integrated into the rotating cap, and the torsion spring is mounted on the terminal unit body. This merging reduces the number of separate components while maintaining strong connection capability.
Solution Approach 2:
The rotating cap performs multiple functions: it transmits user input force, carries the locking blocks for engagement, and works with the torsion spring for automatic return. This multi-functionality reduces the need for separate components, simplifying the overall structure while ensuring reliable connection.
