Suppressor Cap Interlock for Tool-Free Firearm Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm suppressors often require proprietary tools for tightening and untightening, which can be lost or unavailable in the field, and threaded connections can loosen due to heat, complicating maintenance and cleaning.
Innovation Solution
A suppressor cap design featuring protuberances that rotationally interlock with the firearm's slide, allowing the slide to be used as a wrench for easy attachment and detachment without additional tools, and a modular design for varying lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If proprietary tools are used to tighten and untighten the suppressor cap, then secure attachment is achieved, but tool availability and ease of maintenance deteriorate when tools are lost or unavailable in the field
Solution Approach 1:
The suppressor cap is designed with integrated protuberances that engage with corresponding recesses in the suppressor body, allowing the cap to be tightened and removed using the firearm's own components (such as the magazine or barrel) as leverage, eliminating the need for external proprietary tools while maintaining secure attachment
2Strength
If threaded connections are used to attach the suppressor cap, then secure mounting is achieved, but reliability deteriorates when connections loosen due to heat during use
Solution Approach 1:
The threaded connection is divided into multiple engagement points with the protuberances distributing the mounting load across several contact surfaces rather than a single thread interface, reducing stress concentration and preventing loosening under thermal expansion and contraction during firing cycles
3Strength
If proprietary tools are required for suppressor cap installation, then secure attachment is achieved, but device complexity increases due to the need for specialized tools
Solution Approach 1:
The suppressor cap design incorporates universal protuberance features that can be manipulated using common firearm components already present in the system, making the attachment mechanism multi-functional and eliminating the need for specialized external tools while maintaining secure mounting

AI summary
A suppressed firearm can include a firearm including a slide; and a suppressor configured to mount to the firearm, the suppressor including a suppressor cap, the suppressor cap defining at least one protuberance configured to rotationally interlock with the slide. A suppressor cap can include a flange defining a through hole, the through hole defining an axis; a first lug extending axially outward from the flange, the first lug defining a first radially inner surface; and a second lug extending axially outward from the flange, the second lug defining a second radially inner surface positioned parallel to the first radially inner surface, the axis centered between the first radially inner surface and the second radially inner surface.
