Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional air traffic control systems are used for UAVs, then existing infrastructure can be leveraged, but the systems are inadequate to support the sheer quantity of UAVs expected in flight
Solution Approach 1:
The air traffic control system is segmented into multiple components including a database server storing geographic region data and flying lane definitions, an application server processing flight requests and determining associated flying lanes, and communication modules interfacing with UAVs. This segmentation allows the system to handle large numbers of UAVs by distributing processing tasks across multiple servers and databases rather than requiring a monolithic complex system.
2Reliability
If flying lanes are standardized and managed centrally, then collision avoidance is improved, but communication overhead and system complexity increase
Solution Approach 1:
Flying lanes are pre-defined and stored in the database with specific geographic coordinates, altitudes, and parameters before any UAV operations begin. When a UAV requests flight authorization, the application server simply queries the database for the associated flying lane based on the requested geographic region and parameters, rather than calculating flight paths in real-time. This preliminary preparation of flight data significantly reduces real-time processing complexity while maintaining reliable collision avoidance through standardized lane management.
3Measurement precision
If real-time feedback is collected from all UAVs, then monitoring precision is improved, but network bandwidth and processing requirements increase
Solution Approach 1:
The system extracts and processes only the essential feedback data from UAVs, specifically feedback related to flying lane adherence and operational status. Rather than transmitting all possible sensor data from each UAV, the system focuses on collecting targeted information necessary for monitoring whether UAVs remain within their assigned flying lanes and for emergency shutdown coordination. This selective data extraction maintains monitoring precision while significantly reducing network bandwidth requirements.
4Reliability
If emergency shutdown procedures are implemented for distressed UAVs, then safety is improved, but risk to ground structures and people increases without proper coordination
Solution Approach 1:
The air traffic control system continuously receives feedback from UAVs regarding their operational status, location, and distress conditions. When a UAV is identified as distressed, the system uses this feedback to coordinate an controlled emergency shutdown procedure, directing the UAV to a safe location before shutdown rather than immediate termination anywhere. This feedback-based coordination ensures that emergency shutdowns enhance UAV safety while minimizing risk to ground structures and people through proactive location management.
