Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the emergency starting power supply is coupled to the automotive battery, then the battery can be charged, but the power of the emergency starting power supply is wasted and usage efficiency decreases
Solution Approach 1:
The patent implements dynamic control of the switch module based on real-time detection of electrical parameters. The control module dynamically adjusts the connection state between energy storage module and output interface according to whether the vehicle requires starting, transforming the system from static automatic charging to dynamic conditional power delivery.
Solution Approach 2:
The detection unit continuously monitors electrical parameters and provides feedback to the control module, which then adjusts the switch module state accordingly. This feedback mechanism prevents unnecessary power output by continuously assessing whether the vehicle battery requires emergency starting current.
2Reliability
If the emergency starting power supply automatically outputs power to the battery, then the battery is charged, but the energy storage unit may run out of power and cannot start the automobile
Solution Approach 1:
The detection unit performs preliminary detection of electrical parameters before the control module activates the switch module. This preliminary action ensures that power is only output when the vehicle actually requires starting, preventing premature power depletion while maintaining reliable starting capability when needed.
Solution Approach 2:
The continuous feedback loop between detection unit and control module monitors the state of both the energy storage unit and the vehicle battery, enabling the system to maintain starting capability only when necessary and prevent power depletion through real-time assessment.
3Speed
If the switch module is turned on without steady state control, then power is delivered quickly, but the switch state may be unstable
Solution Approach 1:
The capacitor is introduced as an intermediary element between the control module and the switch module. It acts as a mediator that filters and stabilizes the control signal, ensuring the switch module transitions to and maintains a stable on-state once activated, while still allowing quick power delivery when needed.
