Gas-Powered Gun With Coaxial Plenum for Added Gas Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas-powered guns face limitations in plenum size, with add-on devices being impractical and conventional sleeves not designed to withstand high pressure.
Innovation Solution
A coaxially arranged plenum chamber formed around the barrel, integrated with sealed sleeves to increase plenum size without additional components, using a sleeve with thicker walls to withstand regulated pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If add-on plenum devices are used to increase plenum size, then plenum volume is improved, but device complexity and impracticality increase
Solution Approach 1:
The plenum chamber is merged with the barrel structure by forming it coaxially around the rear portion of the barrel. This integration eliminates the need for separate add-on plenum devices, reducing device complexity while increasing plenum volume. The plenum and barrel become a unified structure rather than separate components.
Solution Approach 2:
The plenum chamber is nested within the barrel structure, specifically formed coaxially around the rear portion of the barrel. This nesting arrangement allows the plenum to be housed within the existing gun geometry, increasing plenum volume without requiring additional external components or increasing the overall gun size.
2Object-affected harmful factors
If conventional sleeves are used around the barrel, then user protection is improved, but pressure resistance is insufficient
Solution Approach 1:
The sleeve is designed with thicker walls compared to conventional sleeves, changing the structural parameter to withstand regulated pressure. This parameter change allows the sleeve to serve dual purposes: protecting the user from heat and resisting the pressure generated during gas-powered operation.
Solution Approach 2:
The sleeve is designed to perform multiple functions simultaneously: it protects the user from the hot barrel, withstands the regulated pressure during operation, and serves as an integral part of the plenum chamber structure. This multi-functionality eliminates the need for separate protective and pressure-resistant components.
