Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UAVs use traditional wireless communication networks with multiple base station signals, then network coverage is provided, but signal interference increases and computing resources are wasted due to frequent signal switching
Solution Approach 1:
The patent segments the wireless communication coverage area into dedicated aerial corridors defined by specific beam paths. Each corridor is assigned to a particular UAV or flight path, separating aerial communication traffic from terrestrial base station signals. This segmentation eliminates signal interference and reduces the need for frequent signal switching, thereby improving reliability while optimizing computing resource usage.
Solution Approach 2:
The patent introduces an intermediary system consisting of beamforming antenna arrays and a beam management server. These intermediaries create dedicated communication beams that act as private channels for UAVs, mediating between the UAV and the traditional wireless network. This intermediary layer isolates UAVs from terrestrial signal interference while maintaining network connectivity.
2Ease of operation
If traditional cell sites emit signals in predictable locations, then mobile devices can easily connect, but surveillance devices can spoof cell sites and compromise security
Solution Approach 1:
The patent applies dynamic beamforming where the antenna arrays continuously adjust beam direction, angle, and orientation based on real-time UAV positions and flight paths. This dynamic behavior makes the communication signals unpredictable and difficult to spoof, as the beams change their characteristics continuously rather than remaining static like traditional cell sites.
Solution Approach 2:
The system changes multiple parameters of the communication signals including beam direction, angle, orientation, and temporal variation. By continuously modifying these parameters, the system creates a communication environment that is resistant to spoofing while maintaining reliable connection for authorized UAVs.
3Object-generated harmful factors
If beamforming antenna arrays create focused beams for UAVs, then signal interference is reduced, but device complexity increases
Solution Approach 1:
The patent implements a universal beamforming system where a single set of antenna arrays serves multiple functions: creating communication beams for UAVs, managing signal interference, providing security through dynamic beam patterns, and enabling flexible flight path routing. This multi-functionality justifies the added complexity by delivering multiple benefits from one integrated system.
