Firearm Suppressor with Radial Outer Chamber for Gas Trapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms produce undesirable acoustic noise levels, which can reveal the operator's location and damage hearing, and existing suppressors often alter the projectile's speed and trajectory by diverting discharge gases.
Innovation Solution
A firearm suppressor design featuring a central longitudinal chamber and an outer chamber in fluid communication, with a baffle that directs discharge gases backward past the projectile to trap them, minimizing the impact on the projectile's speed and trajectory while reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional suppressor baffles divert gases away from the bore line, then acoustic noise levels are reduced, but the projectile's speed and trajectory are altered
Solution Approach 1:
Instead of diverting gases forward or sideways as in conventional suppressors, this invention inverts the approach by directing discharge gases backward past the projectile through the outer chamber. The baffle is positioned to channel gases rearward, opposite to the projectile's forward motion, thereby reducing noise without interfering with the projectile's forward trajectory and speed
Solution Approach 2:
The invention introduces a radial dimension by using an outer chamber that extends radially outward from the central longitudinal chamber. This three-dimensional gas diversion pathway allows gases to be directed backward in a radial outer region without intersecting the central bore line where the projectile travels, separating the noise reduction function from the projectile path
2Object-affected harmful factors
If conventional suppressor baffles divert gases away from the bore line, then acoustic noise levels are reduced, but the projectile's trajectory is altered
Solution Approach 1:
The gas diversion direction is inverted to flow backward past the projectile rather than forward or sideways. This backward flow through the outer chamber creates a separation between the gas flow path and the projectile's forward trajectory, preventing gas interference with trajectory while maintaining noise reduction
Solution Approach 2:
The suppressor is segmented into distinct functional zones: a central longitudinal chamber for projectile passage and an outer chamber for gas diversion. This segmentation allows independent optimization of projectile trajectory (through the central chamber) and noise reduction (through the outer chamber gas flow path)
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 reduces acoustic noise with minimal alteration to the projectile's speed and trajectory, improving noise reduction while maintaining bullet performance.

AI summary
A firearm suppressor can comprise a central longitudinal chamber adapted to facilitate passage of a projectile fired from a firearm through the central longitudinal chamber. The firearm suppressor can also comprise an outer chamber disposed radially outward of the central longitudinal chamber, the outer chamber being in fluid communication with the central longitudinal chamber via an opening. The firearm suppressor can further comprise a baffle disposed in the outer chamber and defining a forward portion of the outer chamber and a rearward portion of the outer chamber. The forward portion of the outer chamber can contain the opening such that discharge gases associated with the projectile enter the forward portion of the chamber and are directed backward past the baffle to the rearward portion of the outer chamber where the discharge gases are at least temporarily trapped behind the projectile to reduce or prevent alteration of a trajectory or a speed of the projectile by the discharge gases.
