Keyed Quick-Connect Muzzle Accessory for Tool-Free Barrel Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching muzzle accessories to firearm barrels are time-consuming, require specialized tools, and are not suitable for frequent removal and replacement, often leading to damage and inefficiency.
Innovation Solution
A muzzle accessory assembly featuring a lock mechanism with a pin and guide slot that allows for quick alignment and secure attachment to a firearm barrel without specialized tools, using a keyed receptacle and detent system for easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If threaded attachment methods with high torque are used, then secure attachment is achieved, but specialized tools and bracing equipment are required
Solution Approach 1:
The attachment system is divided into separate functional components: a quick-connect body with keyed receptacle and a lock mechanism with pin. This segmentation allows the attachment to be secured through simple manual manipulation rather than requiring complex threading operations with specialized tools.
Solution Approach 2:
A pin acts as an intermediary element that engages with a guide slot to control the lock mechanism. This simple pin-groove interaction mediates between the user's manual input and the locking action, eliminating the need for specialized bracing equipment and high-torque tools.
2Stability of the object's composition
If set screws are used to prevent rotation, then alignment is maintained, but repeated tightening results in stripping and damage
Solution Approach 1:
The system transitions from static set screws that require repeated tightening to a dynamic lock mechanism with a pin that moves along a guide slot. The pin automatically adjusts its position as the accessory is attached, maintaining alignment stability without repetitive mechanical stress on single points.
Solution Approach 2:
The keyed receptacle and pin mechanism are self-aligning and self-locking. When the accessory is inserted, the key and keyed receptacle automatically align the components, and the pin engages with the guide slot to prevent rotation, eliminating the need for external alignment tools and repeated tightening operations.
3Reliability
If traditional attachment methods are used, then secure connection is achieved, but frequent removal and replacement is time-consuming
Solution Approach 1:
The keyed receptacle and key are pre-configured to guide the attachment process. The key's geometry preliminarily establishes the correct alignment and insertion path, allowing the user to quickly attach or remove accessories without time-consuming alignment procedures or specialized tools.
Solution Approach 2:
The lock mechanism with pin is extracted as a separate, simple component that can be manually operated. This extracted locking mechanism allows for rapid engagement and disengagement by simply moving the pin along the guide slot, enabling frequent attachment and removal without the time investment required for threading, shimming, or set screw adjustments.

AI summary
A muzzle accessory for coupling to a firearm barrel, the firearm barrel including a chamber for receiving a firearm round, a firing tube extending distally from the chamber to a distal end of the firearm barrel, the muzzle accessory can comprise a main body having a proximal end, a distal end, a through-channel extending longitudinally between the proximal end and the distal end, and a keyed receptacle within the through-channel; and a lock coupled to the main body, the lock being positionable into an unlocked position to permit insertion of the distal end of the firearm barrel within the through-channel of the main body, the lock being further positionable into a locked position to prevent removal of the distal end of the firearm barrel from the main body after the firearm barrel is inserted into the through-channel.
