Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional power supply systems are designed to achieve high efficiency, then energy conversion efficiency is improved, but manufacturing variations and environmental changes cause efficiency to degrade over time
Solution Approach 1:
The system continuously measures actual efficiency through metering circuits and feeds this information back to the controller, which then adjusts control parameters to maintain optimal efficiency despite manufacturing variations and environmental changes
Solution Approach 2:
The controller dynamically modifies control parameters such as switching frequency, duty cycle, and voltage levels based on measured efficiency and environmental conditions, allowing the system to adapt to component aging and temperature variations
2Device complexity
If power supply systems use fixed control parameters, then device complexity is reduced, but performance cannot adapt to environmental changes and component aging
Solution Approach 1:
The system transitions from static fixed parameters to dynamic adjustable parameters that automatically adapt to changing conditions including temperature, load, and component aging, with the controller modifying parameters in real-time based on sensor feedback
Solution Approach 2:
The power supply system performs self-diagnosis and self-optimization by measuring its own efficiency and automatically adjusting control parameters without external intervention, enabling adaptive performance maintenance throughout the system lifecycle
