Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pins are made rotatable to improve adaptability to different power socket positions, then adaptability is improved, but electrical connection stability deteriorates during rotation
Solution Approach 1:
The patent implements a rotatable pin assembly that allows dynamic adjustment of the plug's orientation. The rotation mechanism enables the pins to adapt to different power socket positions while maintaining reliable electrical connection through spring-loaded elastic clamping members that ensure continuous contact during rotation and positioning.
Solution Approach 2:
The patent introduces elastic clamping members as intermediary elements between the pins and the rotatable seat. These clamping members act as mediators that maintain stable electrical connection during rotation by providing continuous contact pressure, thus resolving the contradiction between rotatability and connection stability.
2Ease of operation
If pins rotate freely to improve ease of operation, then ease of operation is improved, but harmful factors such as arc sparks and fire risks increase due to unstable connections
Solution Approach 1:
The patent employs spring-loaded elastic clamping members that pre-compress against the pins to maintain continuous electrical contact during rotation. This beforehand cushioning through elastic force prevents unstable connections, arc sparks, and fire risks by ensuring reliable contact throughout the rotation process.
Solution Approach 2:
The patent converts the potential harmful effect of loose connections during rotation into a beneficial elastic clamping force. The spring-loaded clamping members use elastic deformation to maintain continuous contact, transforming what could be a harmful unstable connection into a reliable electrical connection that prevents arc sparks and fire hazards.
