Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the drone flies high to capture lightning in a wide area, then the coverage area is improved, but the conductor cable length increases leading to increased load and accident risk
Solution Approach 1:
The system divides the lightning induction task into multiple segments by deploying multiple drones instead of using one drone with an extremely long cable. Each drone manages a shorter conductor cable segment, collectively covering a wide area while maintaining manageable cable lengths for each unit.
Solution Approach 2:
The system transitions from a single-point induction approach to a multi-point distributed induction approach. By deploying drones in three-dimensional space at different positions and altitudes, the system achieves wide-area coverage without requiring any single drone to fly at excessively high altitudes with prohibitively long cables.
2Reliability
If the conductor cable is made longer to reach ground targets from high altitude, then the induction capability is improved, but the load on the drone increases due to cable weight and wind pressure
Solution Approach 1:
The total induction task is segmented across multiple drones, each handling a portion of the overall cable system. This segmentation allows each drone to manage a shorter, lighter cable segment, reducing the weight burden and wind pressure load on individual drones while maintaining effective lightning induction capability across the entire system.
Solution Approach 2:
The system combines multiple drones with moderate-length cables to achieve the cumulative effect of a single drone with an extremely long cable. By merging the capabilities of multiple units, the system attains wide-area induction capability without the prohibitive weight and control issues associated with a single ultra-long cable system.
3Length of moving object
If the conductor cable is made longer to extend reach, then the induction range is improved, but the risk of contact with ground objects increases
Solution Approach 1:
The system segments the conductor cable into multiple shorter sections, each managed by a separate drone. This segmentation inherently reduces the risk of any single cable segment contacting ground objects, as shorter cables have a lower probability of reaching the ground and entangling with obstacles. The distributed architecture also provides redundancy, so contact with one segment does not compromise the entire system.

AI summary
A lightning induction system includes a plurality of flight vehicles 3 that fly between a lightning originating point 1 in the sky where lightning is generated and a ground surface 2. The flight vehicles 3 each include: a flight unit 10 that generates lift force and propulsion force; a conductor cable 20 that is engaged with the flight unit 10, extends downward, and has a predetermined length; and a weight unit 30 connected to the lower end of the conductor cable 20. The flight unit 10 is disposed in a Faraday cage 11. The Faraday cage 11 has a sphere shape, and the flight unit 10 is fixed by a support pillar 12 extending downward from the inner side of the top of the sphere.
