Drone Defense Net Capture Mechanism for Controlled Neutralization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing defense systems are inadequate to safely and reliably counter the threat of third-party drones, particularly in sensitive areas like nuclear power plants and crowded stadiums, especially when drones operate in swarms or autonomously, as they cannot prevent drones from falling uncontrolled or effectively neutralize the threat without risking harm to people.
Innovation Solution
A drone defense system comprising a defense drone equipped with a capture device, such as a net, and a control unit that coordinates multiple sensor and defense systems, including radar, imaging, and jamming capabilities, to detect and neutralize third-party drones, ensuring safe and controlled removal or destruction without endangering people.

Engineering Contradiction Analysis
1Measurement precision
If known anti-drone systems from prior art are deployed, then drone detection capability is improved, but the risk of uncontrolled drone falls and potential harm to people increases
Solution Approach 1:
A capture device in the form of a net is introduced as an intermediary element between the interceptor drone and the third-party drone. The net serves as a mediating structure that enables controlled capture of the intruding drone, preventing uncontrolled falls while maintaining detection and response capabilities. The net is deployed from the interceptor drone to envelop and secure the target drone safely.
Solution Approach 2:
The capture net is designed as a disposable or easily replaceable component that can be deployed quickly and discarded after use. This allows the system to focus on preserving valuable areas and people while using a simple, inexpensive capture mechanism that doesn't require complex recovery or maintenance procedures.
2Reliability
If powerful prior art anti-drone systems are used, then drone neutralization capability is improved, but the risk of undesirable incidents and harm to people increases
Solution Approach 1:
The system converts the potentially harmful kinetic energy and momentum of the intruding drone into a beneficial capture event. By using the drone's own forward motion to drive it into the deployed net rather than using high-energy destruction methods, the system neutralizes the threat while minimizing harmful effects. The drone's momentum becomes part of the capture mechanism rather than a destructive force.
Solution Approach 2:
Instead of using high-energy weapons to destroy drones from a distance, the system inverts the approach by using a passive net that waits for the drone to come to it. The interceptor drone acts as a mobile platform deploying the net, allowing the capture to occur through the intruding drone's own movement rather than through active destruction forces.
3Ease of manufacture
If simple and inexpensive defense systems are used, then manufacturing and assembly cost is reduced, but the ability to safely and reliably defend against third-party drones deteriorates
Solution Approach 1:
The defense system is segmented into three main components: a defense drone (interceptor), a capture device (net), and a control system. This segmentation allows each component to be optimized independently - the drone can be a standard multicopter platform, the net can be a simple mesh structure, and the control system can be a basic flight controller with added capture logic. This modular approach reduces manufacturing complexity while maintaining effective defense capability.
Solution Approach 2:
The defense drone is designed as a universal platform that can perform multiple functions: normal flight operations, sensor detection of intruding drones, navigation to target drones, and deployment of the capture net. This multi-functionality eliminates the need for separate specialized systems, reducing overall system complexity and manufacturing costs while maintaining reliable defense capability.
