Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the existing National Airspace System (NAS) air traffic control network is used for UAVs, then the UAVs can operate within established air traffic infrastructure, but the system becomes impractical due to the sheer quantity of UAVs that need to be managed
Solution Approach 1:
The air traffic control system is segmented into multiple Unmanned Aircraft Service Stations (UASS) that each manage specific geographic regions or groups of UAVs. This segmentation allows the overall system to handle large quantities of UAVs by distributing control responsibilities across multiple independent stations rather than overwhelming a single centralized NAS system.
Solution Approach 2:
A dedicated UAV air traffic control network acts as an intermediary between the existing NAS and the large fleet of UAVs. This intermediary layer translates and adapts NAS protocols for UAV-specific needs while managing the sheer volume of UAV communications, preventing direct overload of the NAS infrastructure.
2Productivity
If drones are used for package delivery applications, then delivery efficiency and speed are improved, but collision risk and air traffic management difficulty increase due to the large number of concurrent drones
Solution Approach 1:
The air traffic control system implements continuous feedback loops that monitor UAV positions, velocities, and flight paths in real-time. This feedback enables dynamic adjustment of flight paths and speed commands to maintain safe separations between UAVs, preventing collisions while allowing high-density operations for efficient package delivery.
Solution Approach 2:
The system dynamically adjusts flight parameters such as speed, altitude, and route for each UAV based on real-time traffic conditions. This dynamic control allows the system to optimize delivery efficiency while maintaining collision avoidance, as UAVs can adapt their flight patterns response to changing traffic density and potential conflict situations.
3Extent of automation
If autonomous flight control is implemented for UAVs, then operational efficiency and reduced human intervention are improved, but communication requirements and system reliability challenges increase
Solution Approach 1:
The system implements beforehand cushioning by establishing redundant communication channels and pre-planned contingency protocols for autonomous UAVs. Before autonomous operations begin, the system ensures multiple communication paths are available and backup control mechanisms are in place, cushioning against potential communication failures that could compromise autonomous flight reliability.
Solution Approach 2:
The communication system adapts parameters such as transmission power, frequency, and data rate based on operational conditions and UAV autonomy levels. This parameter adjustment optimizes communication reliability for autonomous UAVs, ensuring that control signals and status information are transmitted reliably even in challenging electromagnetic environments or during high-traffic operations.
