Solution Overview
Problem
Existing emergency vehicle rescue devices face issues with relay persistence and incorrect connections, leading to potential short circuits and reduced relay lifespan due to inappropriate operation when connection lines are disconnected or incorrectly connected.
Innovation Solution
A battery rescue activating reset device with a connection line that automatically resets the electric switch by disconnecting the reset line when the anode or cathode connection lines are removed from the battery, preventing incorrect operations and ensuring the relay is not conductive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the relay is used as a switch for the emergency car rescue device to power the vehicle battery, then the device can provide high current loading capability, but the relay cannot be reset when the connection lines are disconnected, leading to potential short circuits and reduced relay lifespan
Solution Approach 1:
The patent implements a feedback mechanism where the control circuit continuously monitors the connection state of the connection lines. When the connection lines are disconnected from the vehicle battery, the control circuit automatically detects this state and triggers the reset of the relay switch. This feedback loop ensures that the relay is only activated when properly connected, preventing persistent activation and potential short circuits while maintaining high current loading capability.
2Duration of action of stationary object
If the relay remains turned on when connection lines are disconnected, then the device maintains continuous power capability, but incorrect connections can cause dangerous short circuits and spark due to large instant current
Solution Approach 1:
The patent applies preliminary anti-action by implementing a detection mechanism that checks the connection state before the relay is activated. The control circuit monitors whether the connection lines are properly connected to the vehicle battery terminals before allowing the relay to close. This preliminary check prevents incorrect connections from causing dangerous short circuits and sparks, while still enabling continuous power capability when properly connected.
3Reliability
If manual switch is disposed in the emergency car rescue device for hardware reset, then the relay can be reset, but the operation is not intuitive and user-friendly
Solution Approach 1:
The patent implements self-service by enabling the relay reset function to operate automatically without requiring manual user intervention. The control circuit continuously monitors the connection state of the connection lines and automatically triggers the relay reset when disconnection is detected. This eliminates the need for users to manually operate a reset switch, making the device more intuitive and user-friendly while maintaining reliable reset capability.
4Reliability
If software reset is programmed to reset the relay automatically every few seconds, then the relay can be reset without manual operation, but the reset timing may not coincide with user disconnection actions
Solution Approach 1:
The patent uses feedback-based reset timing where the control circuit continuously monitors the connection state of the connection lines in real-time. When disconnection is detected, the control circuit immediately triggers the relay reset at that moment, rather than waiting for a predetermined time interval. This feedback-driven approach ensures that the reset timing is synchronized with the user's disconnection action, eliminating the time loss associated with fixed-interval software reset while maintaining automatic reset capability.
