Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a camera is embedded onto the knife switch observation window for detection, then the detection operation can be achieved, but the combination may be unstable during long-term detection operation or even drop of the camera or collision therebetween may occur, resulting in camera damage
Solution Approach 1:
The fixing structure is divided into multiple functional components: a limiting sleeve that provides initial positioning, a limiting ring with elastic material that provides friction-based stabilization, and a fixing magnet that provides magnetic attraction for secure mounting. This segmentation allows each component to address specific stability requirements without overcomplicating the overall structure.
Solution Approach 2:
The limiting ring incorporates elastic material that combines friction-based stabilization with flexibility. The fixing magnet utilizes magnetic field properties to provide secure attachment. This composite approach combines different physical principles (friction and magnetism) to achieve reliable camera fixation without requiring complex mechanical structures.
2Productivity
If the knife switch observation window is disposed at a relatively high position for continuous observation, then the detection coverage is improved, but the detection operation requires staff to move to the position through a climbing frame, increasing operation complexity and time
Solution Approach 1:
The system creates an optical copy of the knife switch state through the camera and transmits it to a mobile terminal device. This allows personnel to view the detection results remotely without needing to physically access the high-positioned observation window, eliminating the need for climbing frames while maintaining full detection capability.
Solution Approach 2:
The camera system acts as an intermediary between the knife switch observation window and the personnel. Instead of personnel directly observing from the high position, the camera captures the image and transmits it to the mobile terminal, serving as a mediator that enables remote access and eliminates the need for physical climbing.
3Reliability
If friction is used to hold the camera in place during detection, then the camera can be secured, but the friction may generate heat and cause instability during long-term operation
Solution Approach 1:
The fixing system separates the friction-based stabilization (limiting ring with elastic material) from the primary fixation mechanism (fixing magnet). The elastic material provides initial friction-based stability, while the magnetic attraction provides the primary secure mounting, reducing reliance on friction alone and minimizing heat generation.
Solution Approach 2:
The system replaces pure mechanical friction-based fixation with a magnetic fixation system. The fixing magnet provides secure attachment through magnetic attraction rather than relying solely on friction, which generates heat. This substitution reduces thermal issues while maintaining reliable camera fixation.
