Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual detection of power supply connection errors is used, then the detection process can be performed, but the detection efficiency is low and labor-intensive
Solution Approach 1:
The system performs self-detection of power supply connection errors by automatically comparing voltage values without requiring external manual intervention. The detection device autonomously identifies mismatches between actual and expected voltage values, enabling the system to detect and report errors independently.
Solution Approach 2:
The patent replaces manual mechanical detection methods with an automated electronic detection system that uses voltage measurement and comparison circuits. This substitution eliminates the need for physical inspection and manual testing, significantly improving detection efficiency and reducing labor requirements.
2Measurement precision
If comprehensive checking of power supply connections is implemented, then detection accuracy improves, but the complexity of the detection system increases
Solution Approach 1:
The detection system is divided into independent functional modules: voltage measurement units for each function module, comparison units that match measured values against standard values, and error identification units. This segmentation allows comprehensive checking of multiple power supply connections without creating a monolithic complex system, as each module operates independently and can be implemented separately.
3Speed
If automated voltage comparison is used, then detection speed increases, but the requirement for precise voltage measurement increases
Solution Approach 1:
The system continuously monitors voltage values and provides feedback by comparing measured voltages against standard voltage values. This feedback mechanism enables rapid detection of deviations while maintaining measurement precision through iterative comparison and error identification, allowing the system to achieve both high speed and high accuracy in power supply connection detection.
