Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple UAVs are allowed to fly simultaneously in the same geographic area, then productivity increases, but collision risk and safety issues worsen
Solution Approach 1:
The system segments the airspace into multiple distinct flight lanes with specific three-dimensional boundaries. Each lane is defined by lateral boundaries (left/right edges) and vertical boundaries (minimum/maximum altitudes), creating separated corridors that allow multiple UAVs to operate simultaneously without collision risk. The geographic area is divided into multiple layers, with each layer containing one or more flight lanes that are spatially separated from other lanes.
Solution Approach 2:
The system introduces an intermediary traffic management system that acts as a mediator between multiple UAVs operating in the same geographic area. This system receives flight requests, assigns specific flight lanes to individual UAVs, and monitors their positions in real-time. The intermediary ensures that no two UAVs occupy the same lateral and vertical space simultaneously, thereby preventing collisions while maintaining high productivity.
2Measurement precision
If precise flight paths are defined for UAV navigation, then navigation accuracy improves, but system complexity increases
Solution Approach 1:
The complex navigation problem is simplified by segmenting the airspace into pre-defined flight lanes with clear boundaries. Instead of calculating precise paths for each UAV individually, the system provides standardized lane corridors that UAVs can follow. Each lane is characterized by simple geometric boundaries (lateral edges and vertical altitude limits), making navigation straightforward while maintaining high precision.
Solution Approach 2:
The system performs preliminary action by pre-defining multiple flight lanes with accurate three-dimensional boundaries before any UAV operations begin. These lanes are established with precise lateral and vertical specifications, so when UAVs need to navigate, they simply select and follow the appropriate pre-defined lane rather than calculating new paths in real-time, reducing both complexity and improving accuracy.
3Reliability
If real-time monitoring and control of UAVs is implemented, then safety and collision avoidance improve, but use of energy and computational resources increases
Solution Approach 1:
Real-time monitoring is made more energy-efficient by segmenting the monitoring task into lane-level supervision rather than individual UAV tracking. The system monitors whether UAVs remain within their assigned flight lane boundaries (lateral and vertical) rather than continuously calculating precise positions and predicting collision risks for each UAV. This segmented approach maintains safety while reducing computational energy consumption.
4Adaptability or versatility
If multiple flight lanes and layers are created for UAV traffic management, then adaptability and traffic capacity improve, but device complexity increases
Solution Approach 1:
The system creates multiple flight lanes segmented within different vertical layers to increase traffic capacity and adaptability. Each layer contains one or more lanes with specific altitude ranges, allowing the system to handle varying traffic demands at different heights. This segmented multi-layer structure provides flexible adaptability for different traffic scenarios while maintaining manageable complexity through standardized lane definitions.
Solution Approach 2:
The system adds the vertical dimension to flight lane definitions by creating multiple layers at different altitude ranges. Each flight lane is defined not only by lateral boundaries but also by vertical boundaries (minimum and maximum altitudes). This three-dimensional approach to lane segmentation dramatically increases traffic management flexibility and capacity without proportionally increasing system complexity, as the same lane definition framework extends naturally into the vertical dimension.
