Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single communication channel is used for formation commands and real-time updates, then communication simplicity is maintained, but communication reliability and real-time response deteriorate under dynamic conditions
Solution Approach 1:
The communication system is segmented into two separate channels: a first communication channel for receiving formation commands from the ground control station, and a second communication channel for real-time updates and data exchange among UAVs. This segmentation allows each channel to be optimized for its specific function, improving overall communication reliability without excessive complexity.
Solution Approach 2:
The leader UAV acts as an intermediary between the ground control station and follower UAVs. It receives formation commands via the first channel, processes them, and distributes updated formation information to follower UAVs through the second channel. This intermediary role enables decentralized intelligence while maintaining coordinated control.
2Device complexity
If centralized control is used for all UAVs, then coordination is simplified, but scalability to large formations deteriorates due to communication bandwidth limitations
Solution Approach 1:
The control system is segmented into centralized (ground control station to leader UAV) and decentralized (leader UAV to follower UAVs) components. This allows the system to scale to large formations by distributing control intelligence to individual UAVs while maintaining coordinated control through the leader-follower architecture.
Solution Approach 2:
The system dynamically adapts its control structure by allowing follower UAVs to autonomously adjust their flight paths based on real-time formation updates from the leader UAV. This dynamic autonomy enables scalability without requiring proportional increases in ground station processing power or communication bandwidth.
3Manufacturing precision
If real-time data exchange among all UAVs is implemented, then motion synchronization is improved, but communication bandwidth requirements and system complexity increase
Solution Approach 1:
The leader UAV serves as an intermediary that consolidates formation command information and distributes only essential update data to follower UAVs. This reduces the total data volume required for motion synchronization compared to full peer-to-peer data exchange, while maintaining synchronization accuracy through the centralized coordination role of the leader.
Solution Approach 2:
Instead of exchanging complete state data among all UAVs, the system uses the leader UAV to generate and distribute copied formation reference information to followers. This copying approach maintains synchronization with significantly reduced communication bandwidth requirements.
4Productivity
If autonomous onboard processing is increased, then operational efficiency is improved, but the volume of data requiring transmission to ground stations increases
Solution Approach 1:
UAVs perform autonomous onboard processing of formation commands and real-time flight adjustments, serving themselves without requiring constant ground station intervention. This self-service capability improves operational efficiency while reducing the volume of data that must be transmitted to and from ground stations, as only essential command and status information needs external communication.

AI summary
A method for implementation of a formation flight path coordination for a scalable group of Unmanned Arial Vehicles (UAVs) including a recursive architecture with a leader UAV and a plurality of follower UAVs in communication with the leader UAV, the method comprising the steps of: receiving formation commands for the UAVs of the group from a ground controller station (GCS), the formation commands including positional and velocity information for implementation by onboard processing systems, the formation commands received on a first communication channel established between the leader UAV and the GCS; sending information from the formation commands by the leader UAV to the plurality of follower UAVs belonging to the leader UAV using a second communication channel established between the plurality of follower UAVs and the leader UAV, the second communication channel separate from the first communication channel; receiving updated formation commands for the flight path from the GCS on the first communication channel; and sending information from the updated formation commands by the leader UAV to the plurality of follower UAVs using the second communication channel. Safety features such as collision avoidance and geofencing, as well as GCS configuration are also presented.
