Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used to enable or disable RF signal transmissions during flights, then compliance with aviation regulations can be achieved, but human errors occur leading to potential regulatory violations
Solution Approach 1:
The wireless sensor network automatically detects flight phases using sensor data (accelerometer, barometer, GPS) and self-manages RF transmission states without human intervention. The system enables transmissions during ground operations and disables them during flight, achieving self-service compliance with aviation regulations and eliminating human error in manual switching.
2Reliability
If RF signal transmissions are disabled during entire flight to ensure regulatory compliance, then compliance is maintained, but network functionality is lost during safe flight phases
Solution Approach 1:
The system dynamically adjusts RF transmission states based on real-time flight phase detection. During ground operations, transmissions are enabled for full network functionality. During flight phases detected via sensor data, transmissions are disabled for compliance. This dynamic adaptation allows the network to maintain functionality when safe and ensure compliance when required.
3Extent of automation
If automatic detection of flight events is implemented using sensor data, then manual errors are eliminated, but device complexity increases
Solution Approach 1:
The wireless sensor network uses multi-functional sensor data (accelerometer for motion detection, barometer for altitude changes, GPS for location) that serves both its primary monitoring purposes and flight phase detection. This multi-functionality approach enables automatic compliance management without adding dedicated flight detection hardware, thus managing complexity while achieving high automation.
