Universal Firearm Suppressor Adapter with Compression Feet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm suppressor attachment methods are inflexible, time-consuming, and often require permanent modifications or specialized tools, limiting their versatility and accessibility for various firearm types, and are costly due to the need for custom adapters and machining.
Innovation Solution
A universal adapter system featuring a sheath with compression feet and a drive collar mechanism that allows for tool-less, secure, and concentric attachment of suppressors to firearms, accommodating a wide range of barrel diameters and geometries through adjustable components like a flexible fitment sleeve and bore alignment device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gunsmith machines threads onto the barrel to attach a suppressor, then the suppressor attachment is secure and permanent, but the firearm is permanently altered, increasing cost and time, and reducing adaptability to different firearms
Solution Approach 1:
The adapter serves as an intermediary component between the suppressor and the firearm barrel. It features an inner portion that interfaces with the barrel (via friction fit, set screws, or clamp mechanism) and an outer portion that interfaces with the suppressor (via threads or bayonet mount), thereby enabling secure attachment without permanent modification to the original firearm
Solution Approach 2:
The adapter is designed with universal compatibility features including adjustable inner portions, multiple attachment mechanisms (friction fit, set screws, clamp), and various outer thread configurations, allowing a single adapter design to accommodate multiple firearm types and suppressor models
2Manufacturing precision
If custom adapters are manufactured for specific firearm models, then the attachment precision is high, but the manufacturing cost and inventory complexity increase significantly
Solution Approach 1:
The adapter incorporates universal design elements such as standardized outer threads that can be changed via interchangeable inserts, adjustable inner portions with multiple engagement methods, and modular components that can be configured for different firearm types, allowing one base design to serve multiple purposes without requiring custom manufacturing for each firearm model
Solution Approach 2:
The adapter includes adjustable and interchangeable components such as removable inner portions, replaceable thread inserts, and adjustable clamp mechanisms that allow the same adapter body to be dynamically reconfigured for different firearm calibers and suppressor types, maintaining precision attachment while reducing inventory requirements
3Ease of manufacture
If set screws are used to tighten the adapter to the barrel, then the adapter can be attached without machining, but the set screws can damage the barrel and the attachment is not consistently centered
Solution Approach 1:
The inner portion of the adapter acts as an intermediary between the attachment mechanism and the barrel, distributing contact forces over a larger surface area through friction fit surfaces and clamp mechanisms, thereby eliminating the need for set screws that concentrate force on small points and risk damaging the barrel
Solution Approach 2:
The adapter's inner portion is designed with compliant or flexible features that allow it to conform to slight variations in barrel diameter and geometry, ensuring consistent centering and secure attachment through uniform radial pressure distribution rather than localized set screw contact points
Applied Scientific Principles

AI summary
A fast-attaching, self-aligning, easily adaptable and preferably tool-less suppressor adapter. The novel adapter attaches to the barrel of a firearm while precisely aligning the barrel and adapter using a set of compression feet equidistantly spaced around the perimeter of the adapter. The device is adapted to attach to a wide range of barrel diameters via an easy to fit and inexpensive to manufacture fitment sleeve. Thus, the adapter can be manufactured in a single size and work with most firearms. In addition, the device attaches to the smooth section of barrel thereby eliminating the need for permanently modifying a firearm by threading the barrel.
