Engineering Contradiction Analysis
1Productivity
If the existing National Airspace System (NAS) is used for UAV air traffic control, then the system structure remains simple and familiar, but it cannot handle the vast quantity of UAVs and autonomous flight control requirements
Solution Approach 1:
The patent applies universality by enabling the air traffic control system to handle both traditional aircraft and UAVs through a unified architecture. The system processes flight data, communicates with vehicles, and manages airspace for multiple types of aerial vehicles simultaneously, making the system versatile enough to scale from current aircraft traffic to future UAV-dominated traffic without requiring separate dedicated systems
Solution Approach 2:
The patent segments the air traffic control functionality into modular components: flight data processing modules, communication interfaces, surveillance systems, and control algorithms. This segmentation allows the system to handle vast quantities of UAVs by distributing processing loads across multiple independent modules that can be scaled and configured based on traffic density and vehicle types
2Area of stationary object
If satellite networks are used for UAV communication and air traffic control, then broad geographic coverage and low latency are achieved, but the system requires integration with multiple wireless networks including cellular networks
Solution Approach 1:
The patent merges satellite network communication with cellular network infrastructure to create a hybrid communication system. The system utilizes satellite networks for broad geographic coverage and low-latency control commands, while integrating cellular networks for supplementary communication and data transmission, thereby achieving extensive coverage without relying solely on one network type
Solution Approach 2:
The patent introduces network interface modules as intermediaries that manage communication between UAVs, satellite networks, and cellular networks. These intermediary components handle protocol conversion, signal routing, and data prioritization, simplifying the integration complexity by providing standardized interfaces that abstract the underlying network differences
3Reliability
If UAVs are constrained to fly based on network coverage of cell towers and satellites, then communication reliability is improved, but flight flexibility and operational freedom are reduced
Solution Approach 1:
The patent implements dynamic flight constraints that adjust in real-time based on network coverage conditions. Rather than imposing static no-fly zones, the system continuously monitors satellite and cellular signal availability, dynamically updating permissible flight paths to maintain communication reliability while maximizing flight flexibility within available network coverage areas
