Offset Firearm Sound Suppressor with Rotating Cam Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional concentric, cylindrical firearm sound suppressors with desired internal volumes are too large, obstructing factory sights and preventing firearms from being holstered with the suppressor attached.
Innovation Solution
A selectively orientable firearm sound suppressor with an elongate body and piston assembly, featuring a cam assembly that allows the suppressor to be fixed and rotated relative to the firearm, ensuring it does not interfere with sights and can be holstered without detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the internal volume of the suppressor is increased to suppress more sound, then the sound suppression effectiveness is improved, but the outer diameter becomes too large and obstructs sight lines
Solution Approach 1:
The suppressor uses an offset bullet pathway design where the bullet pathway is positioned away from the longitudinal axis of the suppressor body. This asymmetric configuration allows the internal volume to be distributed more efficiently, providing adequate sound suppression while keeping the outer diameter compact enough to not obstruct sight lines.
Solution Approach 2:
The offset bullet pathway configuration utilizes three-dimensional space more effectively by distributing the internal volume along an offset path rather than concentrically. This dimensional arrangement allows the suppressor to achieve the required internal volume for sound suppression without increasing the outer diameter proportionally.
2Object-affected harmful factors
If the internal volume of the suppressor is increased to suppress more sound, then the sound suppression effectiveness is improved, but the suppressor cannot fit into a holster
Solution Approach 1:
The offset bullet pathway design creates an asymmetric internal volume distribution that reduces the overall outer diameter of the suppressor. This compact external dimension allows the suppressor to fit into standard holsters while maintaining sufficient internal volume for effective sound suppression.
Solution Approach 2:
By utilizing an offset pathway configuration, the suppressor optimizes its three-dimensional space utilization, achieving adequate internal volume for sound suppression without increasing the external dimensions beyond holster compatibility limits.
3Area of stationary object
If the suppressor is made compact to avoid obstructing sight lines, then sight line clearance is improved, but the internal volume is reduced and sound suppression effectiveness decreases
Solution Approach 1:
The offset bullet pathway creates an asymmetric internal configuration that maximizes the use of available space within a compact outer diameter. This allows the suppressor to maintain a small external profile for clear sight lines while providing sufficient internal volume for effective sound suppression.
Solution Approach 2:
The offset pathway design utilizes three-dimensional space more efficiently by distributing the bullet pathway and internal volume along an offset path, enabling the suppressor to achieve adequate internal volume within a compact external diameter.

AI summary
A suppressor for a firearm is provided, wherein the suppressor can be selectively oriented relative to the firearm. The suppressor has an elongate body, a piston assembly and a cam assembly. A piston of the piston assembly can be fixedly attached to the barrel of a firearm. An indexing ring is radially fixed relative to the piston. The cam lever is selectively movable between a second position, in which the indexing ring is fixed relative to the elongate body, and a first position, in which the indexing ring can rotate relative to the elongate body.
