Firearm Suppressor Locking Mechanism with Rotating Collar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing noise suppressor locking mechanisms for firearms loosen during rapid fire use, leading to misalignment and reduced accuracy due to failure to engage discrete locking positions.
Innovation Solution
A locking mechanism that includes a locking arm, notch, and collar system, where the collar's rotation pushes or pulls the locking notch into alignment with locking positions on the muzzle attachment, ensuring a secure attachment even during rapid fire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to the suppressor, then the retention of the suppressor during use is improved, but the locking mechanism only works effectively when it engages discrete locking positions, and when it fails to engage, the suppressor becomes loose
Solution Approach 1:
The locking arm is made movable relative to the suppressor body, allowing it to dynamically engage and disengage from locking positions on the muzzle attachment. This dynamic component enables the locking mechanism to adapt to slight variations in alignment while maintaining secure retention during rapid fire use.
Solution Approach 2:
The locking mechanism is divided into separate components: a locking arm, a suppressor body, and a muzzle attachment with discrete locking positions. This segmentation allows each component to be optimized independently and facilitates easier manufacturing and assembly.
2Manufacturing precision
If the locking mechanism is designed to engage discrete locking positions, then alignment is improved, but the mechanism loosens when it fails to engage such positions
Solution Approach 1:
The locking arm is designed with adjustable parameters including its length, angle, and position relative to the suppressor body. These parameter variations allow the locking mechanism to engage with discrete locking positions on the muzzle attachment while accommodating manufacturing tolerances and maintaining reliable retention.
Solution Approach 2:
The locking arm and locking positions are designed with asymmetric geometries that ensure unidirectional engagement. The locking arm can be pushed into engagement with the locking positions but resists being pushed out, providing secure retention while allowing controlled disengagement when needed.
3Ease of operation
If the locking mechanism uses a collar rotation system, then the locking notch can be pushed into alignment, but the mechanism requires precise alignment during assembly
Solution Approach 1:
The collar is designed to rotate the locking arm into preliminary alignment with the locking positions on the muzzle attachment before final engagement. This preliminary action compensates for initial misalignment during assembly and ensures proper engagement without requiring extremely precise initial positioning.
Solution Approach 2:
The collar acts as an intermediary component between the locking arm and the muzzle attachment. By rotating the collar, the locking arm is gradually brought into alignment with the locking positions, mediating the transition from misaligned to engaged state and reducing the precision required during initial assembly.

AI summary
A novel locking mechanism is provided for a noise suppressor mount for a firearm. The locking mechanism comprises a muzzle attachment comprising a plurality of locking positions, a collar, and a locking arm comprising a locking notch, wherein the collar rotates to move the locking notch in a circular direction into a locking position. In some cases, the locking mechanism further comprises a protection arm comprising a blocking arm, wherein, with the locking notch moved into the locking position and without a muzzle attachment being fully inserted within the collar, the protection arm is set to an engaged state in which the blocking arm has been extended toward the central portion of the collar, thereby preventing subsequent full insertion of a muzzle attachment, and wherein, with the locking notch moved into the locking position and with a muzzle attachment fully inserted, the protection arm is set to a disengaged state.
