Engineering Contradiction Analysis
1Reliability
If the existing air traffic control network is used for UAVs, then air traffic control functionality is provided, but the system becomes impractical due to the sheer quantity of UAVs
Solution Approach 1:
The patent segments the air traffic control system into multiple distributed controllers that manage specific geographic regions or altitude layers. Each controller handles a subset of UAVs, dividing the overall system complexity into manageable portions while maintaining comprehensive coverage of the airspace.
Solution Approach 2:
The patent introduces a new dimension for organizing UAV traffic by implementing three-dimensional flight layers or corridors at different altitudes. This vertical segmentation allows multiple UAVs to operate simultaneously in the same geographic area without conflict, effectively increasing system capacity without proportionally increasing controller complexity.
2Reliability
If real-time weather information is incorporated into flight plan management, then route optimization and safety are improved, but communication and data processing requirements increase
Solution Approach 1:
The patent implements preliminary weather routing where flight plans are pre-adjusted based on forecasted weather conditions before UAVs depart. This proactive approach allows the system to optimize routes in advance, reducing the need for frequent real-time communications during flight and minimizing data transmission requirements while maintaining safety.
Solution Approach 2:
The patent establishes a feedback mechanism where weather data, UAV position, and flight plan adjustments are continuously exchanged between the air traffic control system and UAVs. This closed-loop system ensures that route optimizations are based on current conditions while efficiently managing communication bandwidth through selective data transmission.
3Productivity
If autonomous operation is enabled for UAVs, then operational efficiency is improved, but collision avoidance and traffic management complexity increase
Solution Approach 1:
The patent implements self-service autonomous operation where UAVs independently manage their own navigation, collision avoidance, and flight adjustments using onboard sensors and processors. Each UAV autonomously detects and responds to traffic conditions, eliminating the need for centralized micro-management and reducing overall system complexity while maintaining high operational efficiency.
Solution Approach 2:
The patent introduces an intermediary communication layer that coordinates autonomous UAVs through standardized protocols and shared situational awareness data. This intermediary framework allows autonomous vehicles to interact safely with each other and with air traffic control without requiring complex direct control connections, simplifying traffic management while preserving autonomy.
