Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electricians use separate plug socket detectors and electric current detectors, then each device can perform its specific function well, but the user needs to carry two detectors and incur increased costs
Solution Approach 1:
The patent combines a plug socket detector and an electric current detector into a single integrated device. The plug socket detection function is achieved through input pins that contact socket terminals, while the current measurement function is achieved through a clamp meter with a coil. Both functions share common components including the housing, display unit, and power supply, thereby reducing the need to carry multiple devices while maintaining functional capabilities
Solution Approach 2:
The integrated device performs multiple functions: it can detect plug socket wiring correctness (live wire, neutral wire, ground wire identification) and measure electric current through the clamp meter. The device uses a microcontroller to coordinate different detection modes, allowing a single device to serve multiple purposes that previously required separate tools
2Ease of operation
If electricians carry two separate detectors for different tasks, then each detection function is specialized, but it causes inconvenience and increases cost
Solution Approach 1:
The patent merges two previously separate detectors (plug socket detector and current detector) into one unified device. The device contains both the input pin assembly for socket detection and the clamp meter assembly for current measurement, along with shared components like the display, battery, and control circuitry, thereby reducing the quantity of devices from two to one
