Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an alligator clip is used for automobile start power supply connection, then the connection function is achieved, but if it accidentally hits the vehicle body, a short circuit will be produced generating larger sparks causing damage
Solution Approach 1:
The patent applies preliminary anti-action by incorporating a pull-off detection mechanism that proactively monitors the connection state of the alligator clip. When the clip accidentally hits the vehicle body or becomes disconnected, the detection unit immediately identifies this abnormal state and triggers an automatic disconnection of the power supply circuit, preventing short circuit damage before it can occur. This proactive approach contrasts with passive protection methods.
Solution Approach 2:
The patent implements feedback through a closed-loop detection and control system. The pull-off detection unit continuously monitors the connection status of the alligator clip and provides real-time feedback to the control unit. Based on this feedback, the control unit automatically adjusts the power supply state - maintaining connection when proper contact is detected and automatically disconnecting when abnormal conditions are detected, thereby preventing harmful short circuits.
2Extent of automation
If connection terminals and cables are detected after equipment installation to achieve automatic pull-off function, then the automatic disconnection function is achieved, but detection difficulties arise when short circuits occur
Solution Approach 1:
The patent introduces an intermediary detection mechanism - a pull-off detection unit with dedicated detection electrodes - that serves as a mediator between the alligator clip connection state and the control system. This intermediary specifically monitors the connection status and provides clear detection signals, making it easier to detect connection abnormalities and trigger automatic disconnection without the complexity of general-purpose detection systems.
Solution Approach 2:
The patent applies segmentation by dividing the detection function into specialized components: connection detection electrodes, pull-off detection units, and control units. Each component has a specific function - the detection electrodes contact the alligator clip, the pull-off detection units monitor connection status, and the control unit processes this information to control power supply. This segmented architecture simplifies detection and improves reliability compared to integrated detection systems.

Function Achieved in This Case
The solution provides an automatic disconnection feature that prevents short circuits and ensures the security and reliability of the start power supply by automatically closing the internal output when the clip is idle, thus protecting the vehicle from damage and simplifying detection processes.
