Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If indirect diagnosis based on logic is used to detect relay faults, then the system structure remains simple, but the measurement precision and reliability of fault detection deteriorates
Solution Approach 1:
The patent replaces indirect logical diagnosis with direct physical measurement using a microsensor that detects the position of the movable unit. This substitution of measurement method enables accurate fault detection while maintaining simple relay structure, as the microsensor directly measures the physical state rather than inferring from operational logic.
Solution Approach 2:
The microsensor acts as an intermediary element between the movable unit and the diagnosis system. It converts the physical position of the movable unit into measurable electrical signals, enabling direct and accurate fault detection without complex logical inference chains.
2Loss of time
If relay faults are diagnosed indirectly through logic, then the device complexity remains low, but the loss of time for fault recovery increases
Solution Approach 1:
The microsensor continuously monitors the position of the movable unit in real-time, enabling immediate detection of faults as they occur. This preliminary monitoring action eliminates the time delay associated with indirect logical diagnosis and enables rapid fault recovery by immediately identifying the problematic relay.
Solution Approach 2:
The microsensor provides continuous feedback on the position of the movable unit, enabling real-time monitoring of relay state. This feedback mechanism allows for immediate fault detection and rapid response, significantly reducing fault recovery time compared to indirect logical diagnosis methods.
3Reliability
If specific relays are replaced based on indirect fault determination, then the ease of repair improves, but the reliability of fault recovery deteriorates due to potential misdiagnosis
Solution Approach 1:
The patent replaces indirect logical determination of faulty relays with direct physical measurement using the microsensor. This substitution provides unambiguous identification of the faulty relay's position, ensuring high reliability of fault recovery while maintaining ease of repair through precise localization of the problem.
Solution Approach 2:
The microsensor creates an accurate physical copy or representation of the movable unit's position through electrical signals. This copied information provides reliable and unambiguous identification of the faulty relay state, eliminating the uncertainty and potential misdiagnosis associated with indirect logical methods.
4Loss of information
If indirect logical diagnosis is used, then the device complexity remains low, but the loss of information about specific fault location increases
Solution Approach 1:
The microsensor serves as an intermediary that captures and transmits precise information about the movable unit's position. This direct measurement preserves complete information about the relay's state and location, eliminating the information loss inherent in indirect logical diagnosis methods.
Solution Approach 2:
The patent substitutes indirect logical inference with direct physical measurement, preserving complete and accurate information about fault location. The microsensor's direct measurement of the movable unit's position provides full information about the relay state without the information degradation that occurs in logical deduction chains.
