Drone Defense Ammunition With Delayed Loose Projectile Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drone defense systems are expensive, complex, inflexible, and have limited effectiveness and hit rates due to the constraints of Kevlar cord lengths in shotgun shells, restricting the effective volume and success rate.
Innovation Solution
Ammunition with loose projectiles, released via a pyrotechnic control mechanism without electronics, allowing for a large effective range and increased hit probability by distributing projectiles chaotically after activation, suitable for both rifle and shotgun calibers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If projectiles are connected by Kevlar cords in shotgun shells, then the structure is stable during transport, but the effective volume is limited to a few cubic meters which reduces hit rate
Solution Approach 1:
The patent divides the connected projectile structure into separate, unconnected individual projectiles. Instead of using Kevlar cords to link projectiles into a fixed cluster, the invention employs multiple independent projectiles that remain separate within the shell, allowing them to disperse more freely and occupy a larger effective volume while maintaining transport stability through the shell's containment structure.
2Shape
If Kevlar cords are used to connect projectiles, then the projectile cluster maintains its shape, but the cord length limitations restrict the area of application
Solution Approach 1:
The patent extracts and removes the Kevlar cords from the projectile assembly. By eliminating the connecting cords entirely, the projectiles are free to disperse in three-dimensional space without being constrained by fixed cord lengths, thereby expanding the area of application and effective volume while the shell structure provides the necessary containment during transport.
3Manufacturing precision
If electronic control mechanisms are used for projectile release, then the timing can be precisely controlled, but the system becomes expensive and complex
Solution Approach 1:
The patent employs a simple, inexpensive pyrotechnic delay element instead of expensive electronic control mechanisms. The pyrotechnic element provides sufficient timing control for the projectile release without requiring complex electronics, sensors, or power sources, thereby reducing system complexity and cost while maintaining adequate functional precision for the application.

AI summary
A drone defense ammunition, such as rifle ammunition (e.g., with a caliber of up to 20 mm) or shotgun ammunition (e.g., up to caliber 4), may include projectiles. The ammunition may release the projectiles loosely as a result of an activation occurring with a time delay to firing of the drone defense ammunition.
