Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electroshock weapons face limitations such as requiring direct contact, limited range, safety hazards from wires, and increased risk of injury or death due to projectile velocity, as well as inability to control electrical shock after firing.
Innovation Solution
A wireless electroshock weapon system that uses far-field radio frequency (RF) power extraction to deliver electrical shocks via a projectile, eliminating the need for wires and allowing for controlled and safe administration of shocks at a distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conducted electrical weapons (CEWs) use thin wires to administer shock, then the weapon can fire projectiles at a distance, but the wires limit the range and pose safety hazards
Solution Approach 1:
The patent extracts and removes the wire component from the CEW system entirely. Instead of using thin wires to conduct electricity to the target, the invention uses a projectile with an integrated electrode that contacts the target directly. This eliminates the safety hazards associated with wires while maintaining the ability to deliver electrical shock at a distance.
Solution Approach 2:
The patent replaces the mechanical wire-based electrical connection system with a projectile-based direct contact system. The projectile is fired mechanically and delivers the electrical shock through direct physical contact with the target, substituting the wire-mechanism with a more efficient and safer projectile-mechanism.
2Length of moving object
If long-range electroshock projectiles are fired from a shotgun, then the weapon achieves extended range, but the extreme velocity and momentum increase the risk of death
Solution Approach 1:
The patent applies local quality by concentrating the harmful effect specifically at the point of contact with the target. The projectile is designed to deliver electrical shock only when it makes direct contact with the target's body, rather than relying on high-velocity impact. This localizes the effect to the intended target area while reducing unintended harmful effects from projectile momentum.
Solution Approach 2:
The patent changes the key parameter from velocity-based delivery (shotgun) to contact-based electrical delivery. The projectile is fired at lower velocities sufficient for contact, and the electrical shock parameter is activated only upon contact, changing the delivery mechanism from kinetic energy to electrical energy transfer.
3Reliability
If direct contact electroshock weapons are used, then the weapon can administer shock reliably, but the user must be within arm's reach of the subject
Solution Approach 1:
The patent segments the shock delivery function from the user's direct contact requirement. The weapon system is divided into the launcher (handled by user) and the projectile (delivered to target). This segmentation allows the user to remain at a safe distance while the projectile independently completes the shock delivery function upon contact with the target.
4Productivity
If CEWs are used, then the weapon can fire projectiles, but only one charge may be fired and the electrical shock cannot be controlled after firing
Solution Approach 1:
The patent introduces dynamics by making the electrical shock delivery controllable and adjustable after firing. The projectile contains an integrated circuit that can receive control signals from the user to adjust shock intensity, duration, and frequency. This dynamic control capability allows the user to adapt the shock parameters in real-time based on the situation, unlike static pre-charged CEW projectiles.

Function Achieved in This Case
The wireless system provides a safer, more controlled, and effective means of subduing subjects without the drawbacks of traditional electroshock weapons, offering increased range and reduced risk of injury or death.
Implementation Method 1
The transmitting antenna sends RF energy to the projectile while the projectile is separated from the chamber
Implementation Method 2
The electrical shock is administered via far field radio frequency ('RF') power extraction

AI summary
An electroshock system wirelessly delivers a shock to a subject. The electroshock system may include a launcher, a wireless projectile, a power source, and a wireless power transmitter. The launcher is configured to be grasped by a user. The wireless projectile is configured to detach from the launcher and adhere to a subject. The power source contributes power for the administration of a shock to the subject. The wireless power transmitter delivers said contributed power to the wireless projectile while the wireless projectile is detached from the launcher. The power source and the wireless transmitter may be co-located with the launcher, or may be separate (such as secured to a person or within a vehicle).
