Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If line-of-sight propagation is used for wireless communication, then high-speed data transmission is achieved, but transmission distance is limited due to Earth's curvature and obstructions
Solution Approach 1:
The transmission path is segmented into multiple hops between drones positioned at different locations. Each drone acts as an independent transmission node, relaying data to the next drone in sequence, thereby extending the overall transmission distance beyond what a single line-of-sight link can achieve.
Solution Approach 2:
The system transitions from ground-based transmission to three-dimensional aerial transmission using drones. By positioning drones at various altitudes and locations in 3D space, the system overcomes Earth's curvature and ground obstructions, enabling line-of-sight transmission across much longer distances.
2Length of stationary object
If non-line-of-sight propagation methods are used to extend transmission distance, then transmission distance is increased, but data transmission speed decreases
Solution Approach 1:
Drones serve as intermediary relay nodes between the transmitter and receiver. Each drone is equipped with steerable antennas that maintain direct line-of-sight links with adjacent drones, enabling high-speed transmission through the intermediary nodes without requiring non-line-of-sight propagation methods.
3Reliability
If drones are positioned closer together to maintain communication links, then transmission reliability is improved, but system complexity and number of drones required increases
Solution Approach 1:
The drone positions and antenna orientations are dynamically adjusted to maintain optimal communication links. Steerable antennas on each drone actively track and point toward adjacent drones, allowing for greater spacing between drones while maintaining link reliability through dynamic adaptation rather than fixed close positioning.

direct line-of-sight transmissions such as microwave transmissions are used to transmit between the drones
Implementation Method 2
The winged drones travel generally along the geodesic path and are pushed by the prevailing winds towards a landing location
Data Source
AI summary
Wireless communication is provided over an extended distance using a line or a series of drones traveling along a transmission path between a transmitter and a receiver. The transmitter sends a data signal to a first drone that is within range of the transmitter. The first drone sends the data signal to an adjacent drone in the line of drones which retransmits the data signal to the next drone in line. The data signal is transmitted between drones until it reaches a final drone within range of the receiver. The final drone transmits the data signal to the receiver. As the drones travel along the transmission path, new drones are launched from a location within range of the transmitter to replace drones that land after transmitting a data signal to the receiver.
