Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suppressors for automatic firearms face challenges in reducing audible and visible signatures while maintaining ballistic performance, particularly in semi-automatic and automatic rifles, where back pressure and gas flow issues lead to malfunctions and wear.
Innovation Solution
A suppressor with a mono-core construction and integral flash hider, featuring parallel gas flow paths and outer chambers that evacuate gases independently of the inner chamber, reducing back pressure and enhancing gas mixing and cooling to minimize audible and visual signatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional suppressor designs are used, then audible report is reduced, but gas back flow into the receiver increases causing malfunctions and wear
Solution Approach 1:
The suppressor is divided into multiple independent chambers (inner chamber and outer chambers) that process gas flows separately. The inner chamber handles central gas flow while outer chambers handle peripheral gas flow, preventing gas backflow into the receiver while maintaining suppression effectiveness.
Solution Approach 2:
The patent introduces a radial dimension for gas flow by creating outer chambers that extend outward from the central axis. This multi-dimensional gas flow path allows gases to be directed away from the receiver in multiple directions (radially outward and axially forward) rather than simply linearly, reducing backflow pressure.
2Object-affected harmful factors
If suppressor volume is increased to improve suppression, then audible report is reduced, but device complexity and size increase
Solution Approach 1:
The suppressor volume is segmented into multiple chambers (inner and outer chambers) that can be arranged in a compact configuration. This segmentation allows the total suppression volume to be distributed efficiently in three-dimensional space, achieving effective suppression without excessive overall size or complexity.
Solution Approach 2:
The outer chambers are positioned radially outside the inner chamber, creating a nested configuration where multiple functional chambers are contained within the overall suppressor housing. This nesting approach maximizes the use of available volume while maintaining a compact external dimensions.
3Illumination intensity
If gas flow velocity is increased to reduce visible signature, then flash is reduced, but back pressure on the firearm increases
Solution Approach 1:
The gas flow is segmented into multiple parallel paths through the inner chamber and outer chambers. This segmentation distributes the total gas flow across multiple exit openings, allowing each individual flow path to maintain high velocity for flash reduction while the distributed nature of multiple paths prevents excessive back pressure buildup.
Solution Approach 2:
The suppressor utilizes pneumatic principles by designing the chamber geometry and opening configurations to optimize gas flow dynamics. The outer chambers provide additional flow paths that manage pressure distribution, enabling high-velocity gas ejection for flash reduction while maintaining balanced back pressure on the firearm.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The suppressor effectively attenuates the audible report and reduces the visual signature of firearms, while minimizing back pressure and gas flow into the receiver, thereby improving firearm performance and reducing wear.
Implementation Method 1
a significant portion of combustion gases is directed to flow through the outer chambers in tandem with a portion of combustion gases that flow through the inner chamber
Implementation Method 2
A flash hider is another muzzle accessory configured to reduce the visible signature of a firearm by cooling and redirecting gases exiting the barrel
Implementation Method 3
The outer chambers can be placed in fluid communication with the inner chamber to promote mixing of gases and more effective filling of the suppressor volume
Implementation Method 4
Suppressors are generally configured to slow the release of pressurized gases from the barrel of the firearm, thereby reducing the audible report when discharging the firearm

AI summary
A suppressor has a suppressor body extending from a proximal end portion to a distal end plate. The suppressor defines an inner chamber with a plurality of baffles and a plurality of outer chambers located radially outside of the inner chamber between the suppressor body and an outer housing. An integral flash hider is located in the distal end portion of the suppressor and exits through a central exit opening in the distal end plate. The outer chambers are largely isolated from the inner chamber and evacuate semi-independently from the inner chamber.
