Pistol Compensator Locking Assembly for Rotation Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pistol compensators face issues with unintended rotation and loosening from the barrel, which can compromise their effectiveness in reducing recoil and muzzle flip.
Innovation Solution
A pistol compensator system comprising a compensator, an elastomeric spacer, shims, a spring guide rod, and a spring plug, which uses a combination of an oval rod cavity, a latch extension, and a chamfered plug cavity to secure the compensator to the barrel, preventing rotation and ensuring a stable attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compensator is attached to a barrel using interlocking threads, then the compensator can be securely mounted, but unintended rotation about the barrel may occur leading to misalignment
Solution Approach 1:
The patent introduces an intermediary locking mechanism (set screw, pin, or adhesive) between the compensator and barrel to prevent unintended rotation. This intermediary element mediates the connection, providing both secure attachment and rotational stability without requiring the compensator threads to bear the rotational locking load.
2Stability of the object's composition
If adhesive, set screws, or pins are used to prevent rotation, then rotational stability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the rotational locking function from the primary attachment threads and implements it through a separate, simple locking mechanism. This separation allows the interlocking threads to focus on secure mounting while the extracted locking component (set screw, pin, or adhesive) handles rotational stability, thereby managing complexity through functional decomposition.
3Reliability
If the compensator is tensioned to the end of the barrel, then recoil reduction effectiveness is improved, but the risk of unintended rotation increases
Solution Approach 1:
The patent employs asymmetric tensioning where the compensator is tensioned to the end of the barrel in the axial direction (to maximize recoil reduction) while a separate symmetric locking mechanism (set screw or pin) provides rotational stability. This asymmetric approach allows maximum tensioning force along the barrel axis without compromising rotational stability through the perpendicular locking feature.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents unintended rotation and loosening of the compensator, maintaining its performance in reducing recoil and muzzle flip by ensuring a secure and aligned attachment to the pistol barrel.
Implementation Method 1
The compensator is tensioned to the end of the barrel by the elastomeric spacer and a shim disposed in the barrel cavity between the compensator body and the muzzle face of the barrel
Implementation Method 2
The spring plug of this system comprises a latch extension. The spring guide rod of this system comprises a muzzle end. When this preferred embodiment is installed on a pistol, if the pistol is in battery (slide closed) the latch extension is disposed in the plug cavity, and if the pistol is out of battery (slide back) the muzzle end of the guide rod is disposed in the rod cavity
