Firearm Suppressor Gas Diversion and Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm suppressors can lead to over-cycling of mechanical actions and venting of toxic propellant gases towards the user, especially during extended firing sessions.
Innovation Solution
A firearm suppressor design featuring a suppressor body with external channels, baffles, and a gas port system that diverts propellant gases away from the user and reduces noise levels by directing gases through external channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If excess propellant gases are utilized to operate the mechanical action of the firearm, then the firing cycle is increased, but the mechanical action may over-cycle and toxic gases may vent towards the user
Solution Approach 1:
The suppressor interior is divided into separate chambers: an expansion chamber for noise reduction and a second chamber for gas collection. This segmentation allows propellant gases to be directed away from the user through dedicated pathways, preventing toxic gas exposure while maintaining the ability to utilize gases for operating the mechanical action.
Solution Approach 2:
A valve mechanism acts as an intermediary between the expansion chamber and the exterior, controlling the release of propellant gases. This valve regulates gas flow to operate the mechanical action without allowing uncontrolled venting towards the user, thus maintaining productivity while reducing harmful effects.
2Object-affected harmful factors
If conventional baffles are used to reduce noise, then the report is reduced, but propellant gases build up in the chamber causing over-cycling
Solution Approach 1:
The suppressor is divided into multiple chambers with distinct functions: the expansion chamber with baffles for noise reduction, and a separate second chamber for gas collection and management. This segmentation prevents gas buildup in the noise-reduction chamber while maintaining reliable mechanical action cycling through controlled gas release.
Solution Approach 2:
The system recovers useful propellant gases for operating the mechanical action while discarding excess gases through controlled venting. The valve mechanism enables selective release of gases to maintain reliable cycling without over-cycling, while the baffle system continues to reduce noise effectively.
