Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional flying object operating devices are used, then the device complexity is low, but the reliability is insufficient and malfunctions cannot be prevented
Solution Approach 1:
The abnormality detection unit performs preliminary detection of the operating unit's state before activation. The calculation unit compares detection results with thresholds in advance to determine whether the operating unit is abnormal, preventing malfunction before it occurs rather than responding after failure.
Solution Approach 2:
The system continuously monitors the operating unit through the abnormality detection unit and uses the calculation unit to compare detection results with predetermined thresholds. This feedback mechanism provides real-time information about the operating unit's state, enabling the control unit to make informed decisions about activation and prevent malfunction.
2Reliability
If the operating unit is activated without checking its operability, then the ease of operation is high, but malfunction may occur due to undetected abnormalities
Solution Approach 1:
The operating unit performs self-diagnosis through the abnormality detection unit, which detects its own operational state. The calculation unit automatically compares detection results with thresholds and determines abnormality. This self-service mechanism ensures the unit is functional before use without requiring manual checking, maintaining ease of operation while ensuring reliability.
Solution Approach 2:
The system performs preliminary detection and comparison of the operating unit's state before activation. The calculation unit determines whether the operating unit is abnormal by comparing detection results with predetermined thresholds, ensuring the unit is ready for operation before it is activated, thus preventing malfunction.
3Reliability
If the operating unit can be activated at any time, then the responsiveness is high, but accidental activation may occur leading to safety issues
Solution Approach 1:
The abnormality detection unit continuously monitors the operating unit's state and provides feedback to the calculation unit. The calculation unit compares detection results with thresholds and determines whether activation conditions are met, ensuring the unit is only activated when appropriate and functional, preventing accidental activation while maintaining rapid response capability.
Solution Approach 2:
The system performs preliminary determination of abnormality by comparing detection results with predetermined thresholds before activation. This preliminary check ensures the operating unit is only activated when it is functional and conditions are appropriate, preventing accidental activation while maintaining fast response time through automated real-time monitoring.
