Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of power supply is performed, then the operator can adjust the power supply, but the testing efficiency is low and manual labor is high
Solution Approach 1:
The system enables automatic power supply adjustment through a controller that autonomously calculates required power parameters and controls the power supply array without manual intervention. The controller reads component specifications, determines voltage and current parameters, and automatically adjusts each channel's power output, making the system self-sufficient and eliminating manual adjustment operations.
Solution Approach 2:
The patent replaces manual mechanical adjustment operations with an automated electronic control system. The controller uses electronic calculations and digital control signals to adjust power supply parameters, substituting the mechanical knob-adjustment process with an automated electronic system that reads component specs and directly controls power output based on calculated parameters.
2Measurement precision
If digital indicators of the power supply array are used, then the output voltage and current can be displayed, but the measurements are inaccurate due to power loss during line transmission
Solution Approach 1:
The controller performs preliminary calculations of the required power parameters based on component specifications before actual power delivery. By pre-calculating the exact voltage and current needed at the component terminals, the system compensates for transmission losses in advance, ensuring accurate power delivery despite energy loss during line transmission.
Solution Approach 2:
The system implements a feedback mechanism where the controller continuously monitors power delivery and adjusts parameters based on actual component requirements. The controller reads component specifications, calculates required power, delivers power through the array, and can adjust based on actual performance, creating a closed-loop system that compensates for transmission losses.
3Reliability
If the operator repeatedly calculates power and adjusts the power supply array, then the component can receive the required power, but the testing efficiency is lowered
Solution Approach 1:
The controller performs all necessary power calculations in advance based on component specifications before the actual testing begins. By pre-calculating voltage, current, and power parameters for each channel based on the component's required specifications, the system eliminates the need for repeated calculations and adjustments during testing, saving time while maintaining accuracy.
Solution Approach 2:
The automated controller performs the calculation and adjustment functions that previously required repeated manual intervention. The system autonomously determines power parameters, controls the power supply array, and maintains accurate power delivery throughout testing without requiring operator recalculation or readjustment, thereby eliminating time loss while preserving reliability.
