Pneumatic Rifle Layout for Interchangeable Solid and Liquid Rounds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas-powered rifles are limited to shooting either solid or liquid projectiles, restricting the operator's ability to adapt to different threats and potentially leading to over- or under-application of force, especially in scenarios requiring non-lethal crowd control or counter-small Unmanned Aerial System (c-sUAS) operations.
Innovation Solution
A hand-held pneumatic rifle designed to interchangeably propel solid or liquid rounds using a gas actuator, a firing module, a magazine, a loader, and a barrel, with an electric switch to activate gas release, allowing for high-speed projectile ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional gas-powered rifles are designed to shoot only solid or liquid projectiles, then the device structure is simple, but the adaptability to different threats is limited
Solution Approach 1:
The pneumatic rifle is designed with a universal firing mechanism that can accommodate both solid projectiles and liquid slugs. The system uses interchangeable magazines (solid ammunition magazine or liquid ammunition magazine) while maintaining a common gas actuator, barrel, and firing module, allowing a single device to perform multiple functions for different threat scenarios
Solution Approach 2:
The rifle system is divided into modular components: a reusable core (gas actuator, firing module, barrel) and interchangeable magazines (solid or liquid). This segmentation allows the operator to swap between solid and liquid ammunition types without replacing the entire weapon system, achieving versatility while managing complexity through modularity
2Adaptability or versatility
If a single rifle is designed to handle both solid and liquid projectiles, then the versatility increases, but the device complexity increases
Solution Approach 1:
The system incorporates dynamic adaptability through interchangeable magazines that can be quickly swapped based on operational needs. The firing mechanism dynamically adjusts to handle different projectile types (solid rounds or liquid slugs) through the same gas actuation system, allowing flexible response to changing scenarios without permanent structural modifications
3Object-affected harmful factors
If conventional rifles use fixed ammunition types, then the device complexity is low, but the ability to minimize collateral damage is reduced
Solution Approach 1:
The system enables parameter changes in projectile state (solid vs. liquid) through interchangeable magazines. Solid projectiles maintain shape for precision engagement, while liquid slugs disperse for area coverage, allowing the operator to adjust the physical parameters of the ammunition to match the threat level and minimize collateral damage appropriately

Implementation Method 1
The gas actuator stores and releases compressed gas
Implementation Method 2
The gas actuator stores and releases compressed gas. The firing module includes a chamber for receiving the gas to push forward a bolt

AI summary
A hand-held gun for interchangeably propel a round of one of solid and liquid consistency is provided. The gun includes a gas actuator, a firing module, a magazine, a loader and a barrel. The gas actuator stores and releases compressed gas. The firing module includes a chamber for receiving the gas to push forward a bolt in response to actuation by a trigger. The module is disposed forward of the actuator. The magazine contains ammunition that constitutes the round. The loader laterally receives the round from the magazine and longitudinally receiving the bolt to eject the round. The loader is disposed forward of the module. The barrel directs the round ejected from the loader, and is disposed forward of the loader.
