Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric device includes an upper connector assembly with multiple components (upper connector body, connecting wire, electric connector, metal conductive spring, and metal conductive needle) and a lower connector assembly, then the electrical connection is achieved, but the structure becomes complex and inconvenient to assemble
Solution Approach 1:
The patent combines multiple electrical connection components (connector body, connecting wire, electric connector, metal conductive spring, and metal conductive needle) into an integrated rotatable electric assembly. This assembly includes a rotating shaft core connected to the driving motor, a conductive ring mounting sleeve that rotates synchronously, and metal conductive rings that maintain electrical contact through rotation, eliminating the need for separate upper and lower connector assemblies while achieving reliable electrical connection throughout rotation
Solution Approach 2:
The rotatable electric assembly serves multiple functions simultaneously: it provides electrical connection, enables rotation, and maintains continuous contact during rotation. The conductive rings on the rotating shaft core work together with stationary metal contacts on the base to provide both mechanical support and electrical connectivity, making the system more versatile and less complex
2Adaptability or versatility
If the upper connector assembly rotates 360 degrees circumferentially with the mounting shaft, then the artificial tree can rotate freely, but the electrical connection components become complex requiring multiple connectors and conductive elements
Solution Approach 1:
The patent implements a dynamic electrical connection system where the conductive ring mounting sleeve rotates synchronously with the rotating shaft core, and metal conductive rings are arranged on the sleeve to maintain sliding contact with stationary metal contacts on the base. This dynamic arrangement allows 360-degree rotation while maintaining continuous electrical connection, replacing the static complex multi-component connector assembly with a simpler rotating contact system
