Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If energy saving improvement is performed on each component individually, then energy efficiency of individual components is improved, but overall energy saving effect is limited and costs increase
Solution Approach 1:
The patent merges the control of primary and secondary power supplies into a unified coordination system. The control apparatus simultaneously manages both power supplies by adjusting their output/input voltages based on load conditions, transforming individual component optimization into integrated system optimization, thereby achieving greater energy savings without proportionally increasing complexity
Solution Approach 2:
The patent implements dynamic voltage adjustment for both primary and secondary power supplies based on real-time load rates. The control apparatus continuously monitors load conditions and adjusts voltage parameters dynamically, enabling the system to adapt to changing operational conditions and maintain optimal energy efficiency across different load scenarios
2Loss of energy
If more energy saving components are used, then energy efficiency is improved, but costs increase
Solution Approach 1:
The patent achieves energy savings by changing operational parameters (voltage levels) of existing power supplies rather than replacing them with specialized energy-saving components. By adjusting the output voltage of the primary power supply and input voltage of the secondary power supply within acceptable ranges, the system reduces energy losses without requiring additional hardware investments
3Loss of energy
If voltage of primary power supply and input voltage of secondary power supply are adjusted, then energy efficiency is improved, but voltage stability may be affected
Solution Approach 1:
The control apparatus employs feedback mechanisms to monitor voltage levels and load conditions, adjusting the voltage parameters of primary and secondary power supplies in a controlled manner. This feedback-based coordination ensures that voltage adjustments remain within stable ranges while achieving energy efficiency improvements, preventing voltage instability
