Firearm Sound Suppressor Mounting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound suppressors for firearms face issues such as difficult disassembly due to adhesive deposits, premature failure under sustained high-fire conditions, and ineffective muzzle flash reduction, along with cumbersome and prone-to-failure mounting mechanisms.
Innovation Solution
The design incorporates a flexible inner sleeve for easy baffle removal, a flange and back end member configuration to prevent rear end cap rotation, and a blast deflector to manage radial pressures and temperatures, along with a tapered front end plate to reduce muzzle flash, and a slot-and-tab mounting mechanism for improved alignment and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded joints are used to secure the suppressor to the firearm, then the suppressor can be removably attached, but the rear end cap may unscrew from the housing during removal, causing the suppressor to separate and become difficult to detach
Solution Approach 1:
The mounting mechanism is divided into separate functional components: a threaded bore in the rear end cap for secure attachment, and a detent mechanism with camming surface for controlled detachment. This segmentation allows the threaded joint to provide reliable mounting while the detent mechanism handles the disengagement process, preventing the end cap from unscrewing during removal.
Solution Approach 2:
The detent mechanism incorporates a camming surface that converts rotational motion into linear displacement, dynamically controlling the engagement and disengagement of the detent ball with the cam groove. This dynamic mechanism ensures that during suppressor removal, the detent ball is pushed out of the cam groove before the threaded joint can unscrew, preventing separation and making detachment straightforward.
2Reliability
If the suppressor is designed with a robust housing to withstand sustained high-fire conditions, then durability is improved, but the device becomes heavier and more complex
Solution Approach 1:
The suppressor is divided into modular components including the housing, rear end cap, front end plate, and internal baffles. This segmentation allows the housing to be optimized for withstanding high-fire conditions while other components handle specific functions, reducing the need for overall structural reinforcement and simplifying the design.
Solution Approach 2:
The rear end cap serves multiple functions: it provides the threaded mounting interface, incorporates the detent mechanism for secure attachment and easy release, and acts as a structural support element. This multi-functionality reduces the need for additional components, simplifying the overall structure while maintaining durability.
3Strength
If the inner sleeve is made rigid to maintain structural integrity, then strength is improved, but the baffle becomes difficult to remove for cleaning
Solution Approach 1:
The inner sleeve incorporates a flexible section with a longitudinal split that allows the sleeve to expand radially when force is applied. This dynamic flexibility enables the baffle to be easily removed by pushing the inner sleeve outward, while the flexible section returns to its original shape, maintaining structural integrity during normal operation.
Solution Approach 2:
The inner sleeve uses a flexible membrane structure with a longitudinal split that can elastically deform radially. This flexible design allows the sleeve to maintain its cylindrical shape and structural integrity during normal use while enabling easy baffle removal through radial expansion when force is applied to the flexible section.

AI summary
A method of aligning a firearm sound suppressor (100) includes inserting a front portion of a body of an adapter (168) into a socket (164) of the firearm sound suppressor (100). The method also includes sliding a tab (172) of the adapter (168) into a slot (166) disposed in an interior surface of the socket (164) to rotationally align the firearm sound suppressor (100) relative to a firearm. The method also includes contacting a plug (170) of the adapter (168) against the interior surface in a complimentary engagement. The plug (170) is provided by a frusto-conical external surface of a rear portion of the body. The tab (172) extends from the plug (170).
