Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional electrical connectors are used, then connection is achieved, but friction and wear increase during frequent connection and disconnection cycles
Solution Approach 1:
The electrically conducting element is designed to be movable rather than fixed, allowing it to dynamically adjust its position during connection and disconnection cycles. This movement reduces friction and wear by enabling the contact element to self-adjust to varying connection conditions, thereby improving connection durability while minimizing material loss.
Solution Approach 2:
The force transmission unit actively adjusts the contact force parameter between the electrically conducting element and the pin during operation. By dynamically changing the contact force, the system optimizes electrical contact quality while reducing excessive friction and wear during frequent connection and disconnection cycles.
2Power
If high transmission capacity is provided, then power transfer capability increases, but connector size increases
Solution Approach 1:
The electrically conducting element features a localized contact area that is precisely positioned and dimensioned to concentrate current flow. This local quality optimization allows high transmission capacity through focused contact zones without requiring a proportional increase in overall connector volume.
Solution Approach 2:
The movable electrically conducting element introduces a new degree of freedom in the contact interface, allowing optimization of power transmission in one dimension (contact pressure and area) without directly increasing connector size in other dimensions. The force transmission unit enables independent control of contact parameters separate from overall connector dimensions.
3Reliability
If secure connection is ensured, then connection reliability improves, but risk of inadvertent disconnection increases due to higher locking forces
Solution Approach 1:
The force transmission unit provides active control and feedback on the contact force between the electrically conducting element and the pin. This feedback mechanism allows the system to maintain optimal connection security while preventing excessive locking forces that could lead to inadvertent disconnection, thereby improving reliability without increasing disconnection risk.
Solution Approach 2:
The movable electrically conducting element automatically adjusts its position and contact pressure in response to connection conditions, providing self-regulating connection security. This self-service capability ensures reliable electrical contact without requiring excessive external locking forces, reducing the risk of inadvertent disconnection while maintaining connection reliability.
