Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single power supply module is used for communication testing, then the device complexity is low, but the power supply stability deteriorates during calibration operations
Solution Approach 1:
The power supply system is divided into two independent modules: a first power supply module for primary power provision and a second power supply module (capacitor) for supplementary power. This segmentation allows each module to be optimized for its specific function while maintaining overall system reliability.
Solution Approach 2:
The second power supply module (capacitor) is pre-charged by the first power supply module before actual power delivery is needed. This preliminary charging action ensures that when power instability occurs, the pre-charged capacitor can immediately provide stable power without delay.
2Reliability
If the first power supply module provides power during calibration, then the operation can proceed, but power instability affects testing quality
Solution Approach 1:
The second power supply module (capacitor) acts as an intermediary energy storage device between the first power supply module and the communication board. It absorbs power fluctuations from the first module and delivers stable power to the board, mediating the power delivery to ensure testing quality.
Solution Approach 2:
The system changes the power delivery parameters by switching from direct power supply to capacitor-based power supply when instability is detected. This parameter change involves transitioning the power source from the first module directly to the pre-charged second module, altering the electrical characteristics to achieve stability.
3Reliability
If dual power supply modules are implemented, then power stability improves, but the manufacturing complexity increases
Solution Approach 1:
The first power supply module serves multiple functions: it provides primary power to the communication board and simultaneously charges the second power supply module (capacitor). This multi-functionality reduces the need for separate dedicated charging circuits, simplifying the overall manufacturing process.
Solution Approach 2:
The first power supply module automatically performs the charging of the second module without requiring external intervention or complex control systems. The system self-regulates the power distribution and charging process, reducing manufacturing complexity while maintaining dual-module functionality.
