UAV Crowd Control Agent Dispersion via Modular Drone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for crowd control, such as using canister projectiles with chemical agents, pose risks of injury to law enforcement officials and bystanders, as the agents can be misdirected or cause physical harm.
Innovation Solution
An unmanned aerial system equipped with rotary wings, a pressurized container for crowd control agents, and a nozzle for controlled dispersion, allowing for safe deployment of agents from a distance, along with additional features like navigation, communication, and interchangeable modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If law enforcement officials use canister projectiles containing chemical agents to disperse crowds, then crowd control capability is improved, but the risk of injury to officials and bystanders increases
Solution Approach 1:
The patent introduces an unmanned aerial system as an intermediary device to deliver crowd control agents. The drone carries and disperses chemical agents through its onboard system, positioning itself between law enforcement officials and the crowd. This eliminates direct exposure of officials to chemical agents and physical projectiles, while still achieving crowd dispersion through controlled agent release in the target area.
Solution Approach 2:
The patent replaces the mechanical canister projectile delivery system with an aerial robotic system equipped with chemical dispensing capabilities. Instead of using compressed gas canisters fired from launchers, the system uses a drone with an onboard pressurized container and nozzle system that can precisely control agent release. This substitution eliminates the trajectory and dispersion control issues associated with projectile-based delivery.
2Productivity
If law enforcement officials deploy crowd control agents using traditional methods, then crowd dispersal effectiveness is improved, but the complexity of protective equipment and safety protocols increases
Solution Approach 1:
The patent extracts the crowd control agent delivery function from the law enforcement official's equipment and transfers it to an autonomous unmanned aerial system. The drone is equipped with its own pressurized container, valve system, and nozzle mechanism, completely separating the chemical delivery subsystem from human operators. This extraction eliminates the need for officials to wear protective clothing and handle chemical agents directly.
Solution Approach 2:
The unmanned aerial system operates autonomously to deliver and disperse crowd control agents. The drone navigates to the target area, positions itself appropriately, and releases the chemical agent through its onboard control system without requiring direct human intervention or exposure. The system serves itself in terms of navigation, positioning, and agent delivery, reducing the operational complexity for law enforcement personnel.
