Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an elastic piece structure is used to realize contact and electrical conduction of conductive pieces, then the contact and electrical conduction can be achieved, but the electrical conduction becomes unstable and reliability is poor
Solution Approach 1:
The patent extracts and removes the elastic piece structure from the conductive joint device, replacing it with a rigid conductive piece design. This eliminates the source of instability while maintaining the essential function of electrical conduction between the upper and lower joint components.
Solution Approach 2:
Instead of using an elastic piece to achieve contact, the patent inverts the approach by using a rigid conductive piece with a protruding contact portion that actively engages with the corresponding conductive piece. This inversion transforms the passive elastic contact into an active rigid contact mechanism.
2Ease of operation
If a conductive joint device is mounted at the trunk position to enable rotation, then wire winding can be avoided, but the device becomes complex and difficult to mount and connect
Solution Approach 1:
The conductive joint device is designed to perform multiple functions simultaneously: it provides electrical conduction, enables 360-degree rotation, and facilitates easy mounting and connecting. The integrated design combines the conductive pieces, mounting structures, and rotational mechanism into a single unified component that accomplishes all these functions without requiring separate devices.
Solution Approach 2:
The conductive joint device is segmented into an upper joint component and a lower joint component that can be separately assembled and then connected. This segmentation allows for easier manufacturing, assembly, and maintenance while maintaining the overall functionality of the device.

Function Achieved in This Case
The solution provides a stable and reliable electrical connection with improved convenience in mounting and connecting, preventing wire winding during rotation, and enhancing the overall structural design of both the mounting base and artificial trees.
Implementation Method 1
The conductive component includes a metal conductive spring and a metal conductive pin located on a lower end side of the metal conductive spring. The lower end of the metal conductive spring is pressed against an upper end of the metal conductive pin. The upper end of the metal conductive spring is pressed against and is electrically conducted with the upper electric connecting piece. The lower end of the metal conductive pin is in contact with the lower electric connecting piece and is electrically conducted with the lower electric connecting piece.
