Eccentric Integral Firearm Silencer Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm silencers, particularly can-type silencers, require complex mechanical indexing and often have a large diameter, which can obscure sights and prevent holstering when attached to a handgun.
Innovation Solution
An integral eccentric silencer design that includes a rotatable or slidably mounted elongate body with a propellant gas expansion chamber and a capsule container, where a capsule containing an amorphous solid or liquid ruptures to release contents into the expansion chamber, reducing gas pressure and noise through cooling, allowing for hearing-safe operation and holstering compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If can-type silencers are used, then noise suppression is achieved, but complex mechanical indexing is required
Solution Approach 1:
The silencer is merged with the firearm barrel as an integral component, eliminating the need for separate attachment mechanisms. The silencer bore is coaxial with the barrel bore, creating a unified structure that removes complex mechanical indexing while maintaining noise suppression functionality.
Solution Approach 2:
The silencer is segmented into multiple chambers (first chamber, second chamber, third chamber) with distinct functions. This segmentation allows each chamber to be optimized for specific noise reduction mechanisms while simplifying the overall attachment structure to the barrel.
2Object-affected harmful factors
If large diameter silencers are used, then noise suppression is improved, but sights are obscured and holstering is prevented
Solution Approach 1:
The silencer design transitions from a large-diameter single-chamber structure to a multi-chamber structure with progressively smaller diameters. The first chamber has a larger diameter for initial gas expansion, while subsequent chambers have reduced diameters, allowing the silencer profile to taper and clear firearm sights while maintaining effective noise suppression through the multi-chamber configuration.
Solution Approach 2:
The silencer employs nested chambers where the second chamber is positioned within the first chamber, and the third chamber is positioned within the second chamber. This nested arrangement allows the noise suppression function to be distributed across multiple concentric or sequential chambers with decreasing diameters, enabling the silencer to be compact enough for holstering while maintaining effectiveness.
3Device complexity
If integral silencer design is used, then mechanical indexing is eliminated, but manufacturing precision requirements increase
Solution Approach 1:
The silencer incorporates an eccentric chamber arrangement where the second chamber is offset from the coaxial alignment of the first and third chambers. This asymmetric design provides inherent alignment features that guide the silencer onto the barrel during installation, reducing the manufacturing precision requirements for perfect coaxial alignment while maintaining effective noise suppression through the eccentric chamber configuration.
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 integral eccentric silencer effectively suppresses noise by cooling propellant gases, maintaining firearm sight alignment, and enabling holstering with the silencer attached, achieving a noise reduction of approximately 130 decibels.
Implementation Method 1
a capsule (26) configured to rupture in response to an application of a pressure wave traveling ahead of the projectile while the capsule (26) is installed within the capsule container (22), thereby causing at least a portion of the contents to be released from the capsule (26) and into the propellant gas expansion chamber (20), the amorphous solid or the liquid released from the capsule (26) reducing a temperature of propellant gas
Implementation Method 2
the amorphous solid or the liquid released from the capsule (26) reducing a temperature of propellant gas associated with the pressure wave, which in turn reduces a pressure of the propellant gas
Implementation Method 3
a capsule (26) configured to rupture in response to an application of a pressure wave traveling ahead of the projectile

AI summary
An eccentric firearm silencer includes an elongate body having a projectile entry end, a projectile exit end opposite the projectile entry end, a bore extending through the projectile entry end and the projectile exit end for conducting a projectile therethrough, and a longitudinal axis X passing through the bore. The elongate body is configured to be coupled, rotatably about or slidably parallel to the longitudinal axis X, to a barrel of the firearm at or near the projectile entry end. The elongate body includes a propellant gas expansion chamber disposed adjacent to, and in fluid communication with, the bore for receiving a propellant gas. The elongate body includes a capsule container mounted eccentrically adjacent to, and in fluid communication with, the propellant gas expansion chamber. The capsule container is configured to receive therein a capsule or ablative cartridge containing an amorphous solid or a liquid.
