Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MOS tube-controlled jumper cables are used, then ignition control function is provided, but the MOS tube is prone to burn due to overheating and cannot start large displacement automobiles
Solution Approach 1:
The patent introduces a current-limiting resistor as an intermediary component between the power supply and the MOS tube. This resistor limits the current flowing through the MOS tube, preventing overheating and burnout while still allowing the MOS tube to perform its ignition control function. The resistor acts as a protective mediator that isolates the MOS tube from excessive current conditions.
Solution Approach 2:
The patent implements temperature detection and protective measures before the MOS tube reaches damaging temperatures. The system detects temperature conditions in advance and takes protective actions (such as limiting current or shutting down) before the MOS tube can overheat and fail, thus cushioning against the harmful thermal effects.
2Adaptability or versatility
If power-diode controlled jumper cables are used, then some ignition control is provided, but the diode is prone to burn due to over temperature and there is no short circuit protection
Solution Approach 1:
The patent introduces current-limiting resistors and temperature detection circuits as intermediary protective components. These intermediaries monitor and control the operating conditions of the power diode, preventing over-temperature conditions and short circuits while maintaining the diode's ignition control functionality.
Solution Approach 2:
The patent implements temperature detection and feedback control mechanisms. The system continuously monitors the temperature of the power diode and adjusts its operation based on the detected temperature conditions, providing feedback control that prevents the diode from reaching damaging temperatures.
3Device complexity
If straight-through jumper cables are used, then simple structure is provided, but no reverse connection protection is provided
Solution Approach 1:
The patent introduces a control module with detection circuits as an intermediary between the cable connections and the ignition system. This control module detects reverse connections and prevents operation under such conditions, adding protection functionality without fundamentally changing the basic cable structure.
4Adaptability or versatility
If existing jumper cables are used, then ignition function is provided, but they cannot detect the completion of ignition action and the ignition circuit cannot be disconnected
Solution Approach 1:
The patent implements feedback control by detecting the ignition signal from the automobile's ignition system. When the ignition action is detected as complete, the system automatically disconnects the jumper cable circuit through a control module, preventing continuous current flow and potential damage. This feedback mechanism ensures the circuit is disconnected at the appropriate time.
Solution Approach 2:
The patent combines the ignition detection function and circuit disconnection function into an integrated control module. This merging of functions allows the system to automatically monitor ignition status and control circuit disconnection in a unified manner, ensuring reliable operation.
