Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous connection to flight deck is established to synchronize situational awareness, then information accuracy is improved, but communication cost increases
Solution Approach 1:
The system uses periodic action by establishing continuous connection only when discrepancies are detected between ground-based fuel consumption models and actual aircraft fuel data. Normal operations use intermittent updates, and continuous monitoring activates continuously only when needed, reducing overall communication cost while maintaining information accuracy when required
Solution Approach 2:
The system implements feedback by continuously monitoring fuel consumption data and comparing it against ground-based models. When discrepancies exceed thresholds, the system triggers continuous connection for synchronization. This feedback mechanism ensures information accuracy is maintained precisely when needed while avoiding unnecessary continuous connections during normal operations, thereby reducing communication costs
2Loss of energy
If intermittent fuel updates are provided to ground-based systems, then communication cost is reduced, but information accuracy deteriorates
Solution Approach 1:
The system applies preliminary action by establishing ground-based fuel consumption models before flight using historical data and performance parameters. These pre-established models allow for accurate fuel consumption tracking during flight without requiring continuous real-time data transmission, reducing communication costs while maintaining information accuracy through comparison with actual fuel data
Solution Approach 2:
The system uses feedback by continuously comparing actual fuel consumption data from the aircraft against the pre-established ground-based models. This comparison enables the system to detect discrepancies and trigger continuous connection only when needed, maintaining information accuracy while minimizing communication costs during normal operations
3Measurement precision
If update interval is shortened to improve accuracy, then information accuracy is improved, but communication cost increases
Solution Approach 1:
The system implements periodic action by using short update intervals (continuous monitoring) only when discrepancies are detected between ground-based models and actual fuel data. During normal operations, the system uses longer intervals (intermittent updates), thereby maintaining information accuracy when needed while reducing communication costs during stable flight conditions
4Loss of time
If continuous monitoring is implemented to reduce latency, then information timeliness is improved, but communication cost increases
Solution Approach 1:
The system uses feedback by continuously monitoring fuel consumption data and comparing it against ground-based models. This continuous monitoring enables the system to detect discrepancies in real-time and trigger continuous connection for synchronization, reducing latency only when needed while maintaining cost efficiency during normal operations
Solution Approach 2:
The system applies periodic action by switching between continuous monitoring (short intervals) when discrepancies are detected and intermittent monitoring (longer intervals) during normal operations. This approach reduces system latency precisely when fuel consumption anomalies occur while minimizing communication costs during stable flight conditions
