Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm silencers suffer from increased gas back pressure, material wear, and reduced performance due to the buildup of powder residues in dead-end pockets, leading to decreased muffling effectiveness and shorter service life.
Innovation Solution
A silencer system with a coaxial arrangement of an inner muffler and an outer baffle silencer, featuring a stack of deflection pots with conical inflow trays and gas passages, which creates a parallel circuit and large-volume pressure reduction chamber, reducing back pressure and preventing residue buildup through flushing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional silencers use dead-end pockets for pressure reduction, then muffling performance is improved, but powder residue builds up over time causing the silencer to grow and performance deteriorates
Solution Approach 1:
The patent extracts the harmful dead-end pockets from the silencer design by introducing gas passages that connect all pockets, allowing continuous gas flow through previously stagnant areas. This prevents powder residue accumulation while maintaining the pressure reduction function of the pockets.
Solution Approach 2:
The patent implements continuous gas flow through the silencer by connecting gas passages between all deflection pots and pockets. This ensures that no area remains a dead-end, allowing the silencer to maintain its muffling performance throughout its service life without requiring disassembly for cleaning.
2Reliability
If silencers create pressure reduction chambers to dampen shot bang, then muffling performance is improved, but gas back pressure increases causing material wear and potential weapon destruction
Solution Approach 1:
The patent segments the pressure reduction function across multiple parallel pathways - multiple deflection pots with gas passages and multiple pockets connected in series and parallel arrangements. This distributed approach reduces the pressure buildup in any single chamber while maintaining overall muffling effectiveness.
Solution Approach 2:
The patent introduces gas passages as intermediary channels that connect the deflection pots and pockets, allowing controlled gas flow between chambers. These passages act as mediators that prevent direct high-pressure buildup while still enabling the pressure reduction function necessary for muffling.
3Reliability
If silencers use stacked deflection pots with conical inflow bases, then gas deflection and pressure reduction are achieved, but more powder residues are deposited in dead ends over time
Solution Approach 1:
The patent removes the dead-end characteristic from the deflection pot design by incorporating gas passages that extend from each pot to connected pockets. This extraction of the dead-end feature eliminates the primary mechanism for powder residue deposition while preserving the conical inflow base geometry that provides effective gas deflection.
Solution Approach 2:
The patent ensures continuous gas flow through the deflection pots and pockets via interconnected gas passages. This continuous action prevents powder residues from settling and depositing in the chambers, as the constant gas movement keeps the pathways clear throughout the silencer's operational life.
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 design achieves improved muffling performance, reduced recoil, and extended service life by minimizing back pressure and residue accumulation, resulting in a compact, high-damping capacity silencer system with reduced clogging and enhanced cooling effects.
Implementation Method 1
The inflow cone at the barrel or inlet end of the first silencer acts as a distributor for the gases escaping from the barrel muzzle: The gases escaping directly in the extension of the barrel axis enter the first silencer through the shooting opening of the inflow cone, while those diverging from the axis Gases are directed from the inflow cone into the annular space and the baffle silencer located there.
Implementation Method 2
The deflection pots each have a conical inflow base on the running side, through which the shooting opening passes axially, and—either due to their mutual distances (US 2013/0168181 A1) or due to openings in the pot walls (US 2014/0231168 A1)—radial gas passages. The radial gas passages are closed off like pockets by the surrounding jacket tube, so that there is a sequence of gas collection pockets ('dead ends') in the direction of the shot, which progressively reduce the gas pressure escaping from the barrel muzzle in order to dampen the shot bang.
Implementation Method 3
The muffler system according to the invention results in a parallel circuit between an internal ('first') muffler and a further muffler built coaxially around it, which is formed by baffles in the first annular space between the first muffler and the surrounding jacket pipe. The parallel connection of an internal silencer, for example in a chamber design, and a dead-end baffle silencer reduces the back pressure for the weapon and the shooter.
Implementation Method 4
The axial distance of the inflow cone from the barrel creates a large-volume pressure reduction chamber in the jacket tube, which on the one hand represents the distributor for the parallel connection of the inner first silencer and the outer baffle silencer and on the other hand causes an initial pressure reduction of the powder gases.
Implementation Method 5
The coaxial arrangement of the inner first silencer and the outer baffle silencer results in an extremely compact design with a short overall length and high damping capacity. At the same time, gas flow in the outer dead-endless chicane muffler cools the inner first muffler.
