Drone Protection System with Sliding Wire Faraday Cage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing drone protection systems using Faraday cages restrict the movable range of drones due to fixed connections with wires, causing instability and limited mobility when the wire is tensioned, leading to difficulties in horizontal stabilization.
Innovation Solution
A drone protection system featuring a Faraday cage with a rail-shaped groove on its surface and a wire with H-shaped or T-shaped connection portions that can move along the groove, maintaining connection while allowing the drone to move freely, thereby expanding its movable range and preventing inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a Faraday cage is connected to a wire at a fixed contact point, then lightning protection is provided, but the movable range of the drone is restricted
Solution Approach 1:
The wire connection is changed from a fixed contact to a movable contact that can slide along the Faraday cage surface. This dynamic connection allows the wire to move with the drone while maintaining electrical contact, thereby providing both lightning protection and full mobility without restriction
2Reliability
If a wire is tensioned to provide stable connection, then connection reliability is improved, but the Faraday cage and drone become inclined, making horizontal stabilization difficult
Solution Approach 1:
The wire is allowed to move dynamically along the Faraday cage rather than being fixed at a single point. This eliminates tension-induced inclination while maintaining connection reliability, as the wire can adjust its position to accommodate drone movement without creating stabilizing forces that would tilt the cage
Solution Approach 2:
The constraint that causes the contradiction (fixed wire attachment) is removed entirely. Instead of attaching the wire at a fixed point, the wire is allowed to slide freely along the cage surface, extracting the problematic fixed connection while preserving the essential electrical contact function

Function Achieved in This Case
The system effectively stabilizes the drone in the horizontal direction and increases its movable range by allowing the wire to slide along the Faraday cage, preventing falls and enhancing mobility without compromising lightning protection.
