Actuatable Muzzle Brake with Rotating Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Muzzle brakes increase gas volume directed towards the shooter, causing concussion, necessitating removal and reinstallation for different shooting scenarios, which can alter the point of impact.
Innovation Solution
An actuatable muzzle brake that can be switched between two operating positions: one venting gases sideways and another blocking gas escape, allowing for configuration without removal from the firearm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a muzzle brake is installed to reduce felt recoil, then recoil reduction is improved, but gas volume directed towards the shooter increases causing concussion
Solution Approach 1:
The muzzle brake incorporates a movable sleeve that can be rotated between different positions to dynamically change the venting configuration. This allows the device to adapt between recoil reduction mode (with vents open) and gas containment mode (with vents blocked), resolving the contradiction by making the harmful effect controllable rather than fixed
2Object-generated harmful factors
If the muzzle brake is removed to reduce gas volume towards the shooter, then concussion is reduced, but the point of impact changes requiring reinstallation
Solution Approach 1:
The movable sleeve allows the muzzle brake to maintain a consistent physical configuration on the firearm while dynamically adjusting gas venting. This eliminates the need to remove or reinstall the device, preserving point of impact consistency while controlling gas volume through positional adjustment
3Ease of operation
If the muzzle brake is removed for range shooting, then gas concussion is reduced, but the device must be reinstalled for precise target shooting
Solution Approach 1:
The actuatable sleeve enables users to switch between operational modes by simple rotation while the device remains mounted on the firearm. This eliminates the time-consuming process of removal and reinstallation, allowing immediate switching between range and precision shooting modes
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
Enables easy configuration between recoil reduction and gas containment modes, maintaining consistent point of impact without needing to install or remove the muzzle brake.
Implementation Method 1
muzzle brakes reduce the felt recoil by venting expanding propellant gases in a direction transverse to the direction of extension of a barrel of the firearm through vents in the muzzle brake attachment
Implementation Method 2
a sleeve (122) that is rotatable relative to the body (102) between a first position, in which the multiple apertures (126) align with the multiple vents (114), and a second position, in which the multiple apertures (126) do not align with the multiple vents (114)

AI summary
A side-discharge muzzle brake includes a body, which includes an attachment portion and multiple ports located in the wall of the body. The side-discharge muzzle brake further includes a sleeve sized to slide over a portion of the body and to be rotatable around the body. The sleeve includes multiple openings. The side-discharge muzzle brake includes a securing assembly that allows that sleeve to be rotatable around the portion of the body in two directions for a full 360 degrees of rotation.
