Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conducted electrical weapons (CEWs) face challenges in maintaining a minimum spacing between electrodes at short ranges, which is crucial for effective electrical current delivery and neuromuscular incapacitation, especially in close-quarters situations.
Innovation Solution
The CEW design features a symmetrical circular shape with electrodes deployable at a wider angle, allowing for a minimum spacing of 8 to 16 inches between electrodes when coupled to a target, facilitated by a cartridge system with propellant capsules and activation pins, and an activation system that ensures precise deployment and electrical current delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If electrodes are deployed at typical angles in a conventional CEW design, then the device can deliver electrical current to a target, but at short ranges the minimum spacing between electrodes cannot be obtained
Solution Approach 1:
The patent applies dimensionality change by transitioning from linear electrode deployment to angular deployment. The electrodes are launched at angles greater than 90 degrees relative to the weapon axis, creating a divergent spread pattern. This angular dimension allows electrodes to achieve greater separation distance at short ranges, resolving the contradiction between limited deployment distance and required electrode spacing.
Solution Approach 2:
The patent segments the electrode deployment into multiple independent trajectories. Instead of deploying electrodes along a single linear path, the system launches electrodes along multiple angled paths that diverge from the weapon axis. This segmentation of deployment paths enables each electrode to reach optimal spacing positions independently, even at short ranges.
2Adaptability or versatility
If the CEW is designed for short-range deployment, then it can be used in close-quarters situations, but the minimum spacing between electrodes becomes difficult to obtain
Solution Approach 1:
The patent implements dynamics by making the electrode deployment angle adjustable rather than fixed. The system can vary the launch angles of electrodes to adapt to different range requirements. This dynamic adjustment capability allows the weapon to maintain precise electrode spacing whether deployed at short or longer ranges, resolving the contradiction between adaptability and spacing precision.
Solution Approach 2:
The patent changes the deployment parameters, specifically the launch angle parameter, to optimize electrode spacing. By adjusting the angle parameter to be greater than 90 degrees, the system achieves better spacing control at short ranges. This parameter change transforms the deployment geometry to favor close-quarters effectiveness while maintaining spacing precision.
3Length of moving object
If electrodes are launched at wider angles, then minimum spacing between electrodes is maintained at short ranges, but the device complexity increases
Solution Approach 1:
The patent employs pneumatic mechanisms to achieve wide-angle electrode deployment. By using pressurized gas to propel electrodes along angled trajectories, the system achieves complex deployment patterns without requiring mechanically complex articulation systems. The pneumatic approach simplifies the overall device complexity while maintaining the desired electrode spacing.
Solution Approach 2:
The patent introduces an intermediary deployment mechanism that translates simple activation into complex angular electrode trajectories. The intermediary system (such as a deployment mechanism with angled guides or pneumatic actuators) mediates between the simple trigger pull and the complex wide-angle electrode launch, reducing the perceived complexity at the user interface while achieving the desired electrode spacing.

AI summary
A short-range conducted electrical weapon (“conducted electrical weapon”) may be configured to deploy electrodes having a minimum spacing when coupled to a target at short-range. The conducted electrical weapon may comprise a housing. The housing may comprise a target end opposite a grip end. The grip end may be configured to removably receive a cartridge. The cartridge may house two or more electrodes. The target end may comprise one or more activation buttons or terminals. In response to the activation buttons or terminals being activated, the electrodes may be launched from the cartridge in the grip end. The electrodes may be disposed in the cartridge at an obtuse angle relative to the placement of the opposite electrode. The obtuse angle may enable the electrodes to be deployed effectively at short range.
