Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical pulse incapacitating devices require a bulky and complex pressurized gas reservoir for electrode propulsion, which complicates the design, increases weight, and reduces reliability.
Innovation Solution
A cartridge design utilizing a pyrotechnic charge to generate pressure for electrode propulsion, eliminating the need for a pressurized gas source, with a clamping fit to secure electrodes during combustion and a V-shaped pressure chamber to protect electrical conductors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a pressurized gas reservoir is used to propel electrodes, then electrode projection performance is achieved, but the cartridge becomes bulky and complex
Solution Approach 1:
The patent extracts and eliminates the pressurized gas reservoir from the cartridge system. Instead of using a separate gas storage component, the invention employs a spring-loaded mechanism where the spring is compressed during electrode loading and automatically releases to propel the electrodes forward, thereby achieving electrode projection without the complexity of a gas reservoir system
Solution Approach 2:
The patent replaces the pneumatic system (pressurized gas reservoir) with a purely mechanical spring-based propulsion system. The spring mechanism provides the necessary force for electrode projection through mechanical energy storage and release, eliminating the need for gas compression, storage, and release infrastructure
2Force
If a pressurized gas reservoir with percussion mechanism is used, then electrode propulsion is achieved, but reliability decreases and weight increases
Solution Approach 1:
The patent removes the percussion mechanism entirely from the cartridge design. The spring-based system relies on simple mechanical compression and release rather than requiring a complex percussion ignition system, thereby improving reliability by eliminating additional failure points
Solution Approach 2:
The cartridge is designed as a disposable unit with a simple spring mechanism that can be pre-compressed during loading. The spring provides sufficient propulsion force for a single use, and the entire cartridge is replaced after firing, eliminating the need for complex, high-reliability components that would require maintenance or replacement
3Force
If a pressurized gas reservoir is integrated into the cartridge, then electrode projection is enabled, but the cartridge size and weight increase
Solution Approach 1:
The patent extracts the heavy pressurized gas reservoir from the cartridge and replaces it with a lightweight spring mechanism. The spring can be compressed to store energy during electrode loading and then releases to provide propulsion force, achieving the same functional outcome with significantly reduced weight
Solution Approach 2:
The patent substitutes the heavy pneumatic system with a lightweight mechanical spring system. The spring provides the necessary propulsion force through elastic energy storage and release, eliminating the weight penalty associated with gas cylinders, compression mechanisms, and associated hardware
