Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed cable connection is used, then electrical connectivity is maintained, but rotational movement of components is restricted
Solution Approach 1:
The cable connecting mechanism transforms from a fixed connection to a dynamic rotatable joint. The pivot assembly enables the second member to rotate 360 degrees around the first axis while maintaining electrical connectivity through rotating contact surfaces between conductive portions and elastic members.
Solution Approach 2:
The elastic members act as intermediaries between the conductive portions and the cable. They maintain continuous electrical contact during rotation by elastically deforming to accommodate the rotational movement while ensuring reliable electrical connection.
2Ease of operation
If a rotatable connection is implemented, then rotational movement is enabled, but electrical contact reliability deteriorates
Solution Approach 1:
The mechanism employs dynamic rotating contact surfaces on the conductive portions that maintain electrical contact during rotation. The elastic members dynamically adjust their position through elastic deformation to ensure continuous contact throughout the 360-degree rotation range.
Solution Approach 2:
The conductive portions are designed with curved surfaces that match the rotational movement. The first and second conductive portions have curved contact surfaces that facilitate smooth 360-degree rotation while maintaining consistent electrical contact with the elastic members.
3Adaptability or versatility
If extensive rotation is allowed, then operational versatility improves, but cable entanglement increases
Solution Approach 1:
The cable is extracted from the rotating joint area and routed through a dedicated cable hole in the first member. This separation prevents the cable from being卷入 into the rotational movement, allowing 360-degree rotation without cable entanglement.
Solution Approach 2:
The cable hole in the first member acts as an intermediary that guides the cable away from the rotation zone. The cable passes through this fixed opening rather than being attached to the rotating second member, preventing entanglement during extensive rotational movements.

The mechanism ensures uninterrupted electrical connection and resistance to rotation, preventing cable entanglement and maintaining functionality even during extensive rotational movements of connected components.
Implementation Method 1
A first elastic member can extend through the housing to resist the first curved surface, and can be electrically coupled to the first conductive portion. A second elastic member can extend through the housing to resist the second curved surface, and can be electrically coupled to the second conductive portion.
