Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thicker wires are used to reduce resistance, then voltage drop is reduced, but installation cost and complexity increase
Solution Approach 1:
The system dynamically changes the voltage parameter by detecting voltage drops and activating a boost module to increase voltage output. This allows the use of thinner wires (higher gauge) while maintaining adequate voltage delivery to the charger, thereby reducing installation complexity and cost without sacrificing voltage stability.
2Reliability
If thicker wires are used to reduce resistance, then voltage drop is reduced, but material cost increases
Solution Approach 1:
By implementing dynamic voltage compensation through the boost module, the system can use thinner wires (higher gauge numbers) that require less material while still maintaining reliable voltage delivery. The voltage is increased at the power source to compensate for the higher resistance of thinner wires, reducing material costs without sacrificing voltage stability.
3Adaptability or versatility
If the distance between power source and charger is increased, then installation flexibility is improved, but voltage drop increases
Solution Approach 1:
The system uses feedback from voltage sensors to detect voltage drops caused by increased distance. When a voltage drop is detected, the controller activates the boost module to compensate. This feedback mechanism allows the power source and charger to be located farther apart while maintaining reliable charger operation, thereby improving installation flexibility without sacrificing operational reliability.
4Adaptability or versatility
If the distance between power source and charger is increased, then installation flexibility is improved, but voltage drop causes operational issues
Solution Approach 1:
The feedback mechanism detects voltage drops and triggers the boost module to compensate, allowing greater separation between power source and charger while maintaining operational reliability.
Solution Approach 2:
The system takes preliminary action by monitoring voltage levels and activating the boost module before voltage drops cause operational issues. This proactive approach prevents charger malfunction by compensating for voltage losses due to distance, enabling greater installation flexibility.
