Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If output voltage is increased to meet peak load requirements, then power supply capacity is improved, but power losses increase due to fixed and proportional losses
Solution Approach 1:
The patent implements dynamic voltage adjustment by continuously monitoring load current and modifying output voltage in real-time. The controller increases voltage only when load current indicates peak demand, and reduces voltage when load decreases, transforming the static power supply into a dynamic system that adapts to varying load conditions.
Solution Approach 2:
The patent employs a feedback mechanism where the controller monitors output current and uses this information to adjust output voltage. The current sensor provides continuous feedback about load conditions, enabling the controller to make informed decisions about voltage adjustment, thereby optimizing the balance between power supply capacity and power losses.
2Loss of energy
If output voltage is decreased to reduce power losses, then energy efficiency is improved, but voltage sufficiency deteriorates under peak load conditions
Solution Approach 1:
The system dynamically adjusts voltage based on real-time load conditions rather than maintaining a fixed low voltage. When load current increases indicating peak demand, the controller automatically increases output voltage to ensure sufficient power delivery, thus maintaining reliability while still reducing losses during lighter load conditions.
Solution Approach 2:
The feedback loop continuously monitors load current and uses this information to determine when voltage increase is necessary. The controller compares current levels against thresholds and adjusts voltage accordingly, ensuring that voltage sufficiency is maintained during peak loads while achieving energy efficiency during normal operation.
3Device complexity
If fixed output voltage is maintained for simplicity, then device complexity is reduced, but power efficiency deteriorates due to inability to adapt to varying loads
Solution Approach 1:
The power supply system performs self-adjustment by automatically monitoring its own output current and modifying its output voltage without external intervention. The controller uses built-in current sensing and automatic control logic to regulate voltage based on actual load conditions, enabling the system to optimize its own efficiency.
Solution Approach 2:
The patent changes the output voltage parameter dynamically based on load current conditions. Rather than maintaining a fixed voltage parameter, the system modifies this key parameter in response to varying load requirements, enabling adaptation to different operating conditions and improving overall power efficiency.
