Firearms Suppressor Self-Cleaning Diffuser and Blast Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearm suppressors face issues with particulate matter accumulation, which degrades noise suppression and projectile flow due to the lamination of debris on inner surfaces, and existing disassembly methods fail to effectively prevent particulate matter from adhering to the outer housing and inner core, leading to reduced performance and maintenance challenges.
Innovation Solution
A firearms suppressor design featuring a diffuser with longitudinal slots to direct particulate matter away from the projectile path, surrounded by a blast chamber system that traps debris on its heated surfaces, combined with a scrolled sleeve for easy disassembly and cleaning, preventing particulate matter from adhering to the outer housing and inner core.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a baffled or tortuous pathway is provided for propellant gas egress to optimize noise reduction, then noise suppression is improved, but particulate matter accumulates on inner surfaces degrading performance
Solution Approach 1:
The suppressor is divided into distinct functional zones: a baffled pathway section for noise reduction and a separate clean pathway section for projectile egress. The baffled pathway includes multiple chambers with baffles that create turbulence and noise suppression, while the clean pathway maintains a clear, unobstructed route for the projectile, preventing particulate matter from contaminating the egress path.
Solution Approach 2:
The invention extracts and removes particulate matter from the suppressor interior through a cleaning mechanism that includes a brush or wiper element. This element actively removes accumulated debris from the inner surfaces of the baffled pathway, preventing it from migrating to the clean pathway and degrading performance over time.
2Object-affected harmful factors
If internal volume is maximized to optimize noise reduction, then noise suppression is improved, but suppressor size increases
Solution Approach 1:
The suppressor employs a nested configuration where the clean pathway is positioned concentrically within the baffled pathway. The clean pathway is surrounded by the baffled pathway structure, allowing the noise-reduction volume to be maximized in the outer region while maintaining a compact overall size. This nested arrangement enables effective noise suppression without proportionally increasing the external dimensions of the suppressor.
3Ease of repair
If a slotted sleeve is used to enable easy disassembly, then ease of cleaning is improved, but particulate matter passes through and adheres to outer housing
Solution Approach 1:
The sleeve structure is designed with differentiated properties: the portion interacting with the clean pathway is solid and smooth to prevent particulate matter adhesion, while the outer surface features a patterned or textured configuration that facilitates easy removal from the suppressor housing. This localized differentiation allows the sleeve to maintain cleanliness while enabling easy disassembly for cleaning.
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 solution effectively inhibits particulate matter accumulation within the suppressor, maintaining performance for a higher number of firings before cleaning is required, and facilitates efficient disassembly and maintenance by trapping debris outside the projectile path, enhancing noise suppression and projectile flow.
Implementation Method 1
The diffuser has slots that extend radially outward from an inner passage, allowing exhaust gases and particulate matter to be directed away from the projectile path
Implementation Method 2
The inner surfaces of the blast chamber may provide surfaces to which particulate matter may laminate
Implementation Method 3
These heated surfaces in the path of the travelling particulate matter may provide surfaces to which the debris and residue may attach and adsorb
Implementation Method 4
The flexibility of the inner sleeve may allow it to expand and retract to mute exhaust gas sounds emanating from the firearms suppressor
Implementation Method 5
Suppressor design(s) utilize static geometry to induce pressure loss across the device by effects such as rapid expansion and contraction, minor losses related to inlet and outlet geometry, and induced pressure differential to divert linear flow

AI summary
Methods and systems are provided for a firearms suppressor that comprises a self-cleaning function. In one example the firearms suppressor may include a diffusor circumferentially surrounded by a blast chamber and a scrolled sleeve enclosing the inner core of the firearms suppressor. The combination of the said elements may mitigate accumulation of debris within a projectile path of the firearms suppressor and enable extended operation of the firearms suppressor before cleaning is desired.
