Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed power connectors are used in artificial Christmas trees, then the connection structure is simple, but the connectors cannot rotate and cause wire twisting during tree section rotation
Solution Approach 1:
The connector is designed with dynamic rotation capability, allowing the male and female connector parts to rotate 360 degrees relative to each other while maintaining continuous electrical contact. This transforms the static fixed connector into a dynamic rotating connector that adapts to the rotation of tree sections.
Solution Approach 2:
The electrical connection components are nested within the connector housing structure. The columned contact part and conducting ring are positioned concentrically, with the columned contact part in the center and the conducting ring surrounding it, creating a nested arrangement that enables rotation while maintaining contact.
2Reliability
If fixed connectors are used for quick power connection, then the connection is simple, but power supply is interrupted during rotation
Solution Approach 1:
The electrical connection is designed to maintain continuous contact during the entire rotation process. The columned contact part and conducting ring are positioned and dimensioned to ensure that electrical contact is maintained throughout the 360-degree rotation, preventing any interruption in power supply.
Solution Approach 2:
The connector allows dynamic rotation while maintaining electrical continuity. The rotating parts are designed with appropriate clearance and contact pressure to ensure continuous electrical connection during rotation, combining ease of operation with reliable power supply.
3Reliability
If additional fasteners are added to secure rotating connectors, then connection stability is improved, but the structure becomes more complex
Solution Approach 1:
The connector design uses the elastic deformation of the curved elastic sheet to automatically secure the electrical connection components. The elastic sheet provides self-centering and self-securing functionality through its elastic recovery, eliminating the need for additional fasteners while maintaining connection stability.
Solution Approach 2:
The curved elastic sheet utilizes elastic deformation as a parameter change to secure the connection. By changing the shape parameter of the elastic sheet from flat to curved, it generates elastic restoring force that secures the electrical connection components without requiring additional fastening elements.
