Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only short-circuit detection is provided, then the device complexity is reduced, but the measurement precision and fault detection capability are insufficient
Solution Approach 1:
The detection system is segmented into multiple independent detection modules: short-circuit detection, open-circuit detection, and overload detection. Each module independently detects specific fault types and controls corresponding indicators, enabling comprehensive fault detection while maintaining modular system complexity
Solution Approach 2:
The testing circuit is designed to perform multiple detection functions (short-circuit, open-circuit, overload detection) through a unified structure. The testing switch and detecting circuit serve universal purposes by detecting various fault conditions and controlling multiple indicators, reducing overall system complexity while enhancing measurement precision
2Measurement precision
If comprehensive electrical detection is implemented, then the fault determination accuracy is improved, but the time required for troubleshooting increases
Solution Approach 1:
The adapter performs preliminary detection actions automatically when connected to a load. The testing circuit proactively detects fault conditions (short-circuit, open-circuit, overload) and immediately indicates results through LED indicators, eliminating the need for time-consuming manual troubleshooting and enabling instant fault determination
Solution Approach 2:
Different colored LED indicators provide immediate visual feedback about fault types: green for normal operation, red for short-circuit, yellow for open-circuit, and blue for overload. This color-coded system enables rapid fault identification and determination without requiring technical expertise or extended troubleshooting time
3Reliability
If multiple detection functions are added, then the reliability of fault detection is improved, but the device complexity increases
Solution Approach 1:
Multiple detection functions (short-circuit, open-circuit, overload detection) are merged into a single integrated testing circuit. The testing switch and detecting circuit serve multiple purposes by detecting various fault conditions and controlling corresponding indicators, improving detection reliability while avoiding the complexity of separate independent detection systems
Solution Approach 2:
The adapter performs self-diagnosis through the integrated testing circuit that automatically detects fault conditions and indicates results through LED indicators. This self-service capability improves detection reliability by enabling continuous monitoring without external intervention while maintaining simple circuit architecture
