Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional power supplies use a preset voltage configuration, then the voltage output is stable and reliable, but the power supply cannot accommodate varying voltage and current requirements of different electrical loads
Solution Approach 1:
The power supply controller transitions from a static preset voltage configuration to a dynamic system that continuously adjusts voltage and current output levels based on feedback from electrical load sensors. The control unit modifies operating parameters in real-time to match varying load requirements, enabling adaptability while maintaining system reliability through controlled dynamic operation.
Solution Approach 2:
The controller changes key operating parameters (voltage level and current level) from fixed preset values to variable parameters that can be adjusted within defined ranges. By modifying these parameters dynamically based on load conditions, the power supply achieves versatility across different electrical loads without requiring multiple dedicated power supply units.
2Adaptability or versatility
If the power supply uses fixed voltage and current output, then the device structure is simple, but it cannot efficiently power various electrical loads with different specifications
Solution Approach 1:
The power supply controller is designed as a universal device that can serve multiple electrical loads with different voltage and current requirements through a single unified system. By integrating variable voltage and current control capabilities, the controller eliminates the need for multiple dedicated power supplies, achieving multi-functionality while maintaining reasonable structural complexity through shared control architecture.
Solution Approach 2:
The controller incorporates feedback mechanisms that monitor actual voltage and current output levels along with electrical load conditions. This feedback information is continuously processed by the control unit to automatically adjust operating parameters, enabling the system to adapt to varying load specifications without requiring complex manual reconfiguration or multiple specialized controllers.
3Use of energy by moving object
If the power supply maintains constant preset voltage, then the control system is simple, but the efficiency is reduced when powering loads with different voltage requirements
Solution Approach 1:
The control system transitions from maintaining constant preset voltage to dynamic voltage adjustment based on actual load requirements. By continuously adapting the output voltage level to match the specific needs of connected electrical loads, the system maximizes energy transfer efficiency and minimizes wasted energy, justifying the increased control complexity through significant efficiency improvements.
