Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If additional energy sources (battery or electrical connection) are provided for the measuring device, then the measuring device can operate continuously, but the device complexity and cost increase
Solution Approach 1:
The coil device utilizes the existing current flowing through the fuse link to generate electromagnetic induction, which automatically provides energy to the measuring device without requiring external batteries or electrical connections. The system serves itself by converting the operational current into usable energy for its own electronics.
Solution Approach 2:
The coil device serves dual functions: it acts as both a current sensing element for measurement and an energy generation source through electromagnetic induction. This multi-functionality eliminates the need for separate energy supply components while maintaining continuous operation capability.
2Loss of information
If measuring device and display device are integrated, then real-time feedback of electrical operating values is provided, but the device complexity and energy consumption increase
Solution Approach 1:
The coil device serves as both the energy source and the measurement sensor, while the display device visually presents the measurement results. This integrated approach provides real-time feedback without requiring separate complex subsystems for measurement and display.
Solution Approach 2:
The measuring device continuously monitors the current through the coil and provides real-time visual feedback through the display device, allowing users to immediately see the electrical operating values. This closed-loop feedback system enhances operational awareness without requiring complex external monitoring equipment.
