Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing muzzle devices, such as flash suppressors and muzzle brakes, are inadequate in effectively cooling and dispersing propellant gases, leading to insufficient muzzle flash reduction and lack of versatility in converting between flash suppression and recoil mitigation functions.
Innovation Solution
A muzzle device and blast sleeve design featuring a cylindrical body with radially positioned venting apertures and recesses, a tight bore diameter, and an anti-rotation screw, which allows for improved gas disruption and flame dispersion, and can be retrofitted to existing devices for enhanced flash suppression and recoil mitigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a typical flash suppressor is used, then the device structure is simple, but the propellant gases are not sufficiently cooled or dispersed resulting in inadequate muzzle flash reduction
Solution Approach 1:
The flash suppressor is divided into multiple functional sections: a body portion with transverse vent holes for gas diversion, a forward section with longitudinal vent holes for additional gas dispersion, and a rear section with cooling fins. This segmentation allows different portions of the device to handle specific aspects of gas management, achieving effective flash suppression through coordinated action of multiple specialized features rather than a single complex structure
Solution Approach 2:
The invention extends the gas cooling and dispersal process into the longitudinal dimension by incorporating longitudinal vent holes in the forward section, in addition to the transverse vent holes in the body portion. This multi-dimensional venting approach creates multiple pathways for gas escape in different directions, significantly enhancing flash suppression effectiveness compared to conventional two-dimensional designs
2Adaptability or versatility
If a typical muzzle device is used, then the device serves a single function (either flash suppression or recoil mitigation), but the device lacks versatility for converting between different functions
Solution Approach 1:
The muzzle device is designed with universal functionality by incorporating both flash suppression features (transverse and longitudinal vent holes, cooling fins) and recoil mitigation features (baffles with specific aperture patterns). The device can operate effectively as a flash suppressor, a muzzle brake, or a hybrid system depending on the configuration of internal components, eliminating the need for separate specialized devices and allowing users to optimize performance for different shooting conditions
Solution Approach 2:
The device incorporates dynamic configurability through removable and interchangeable internal components such as baffles and screen inserts. These components can be added, removed, or repositioned to change the device's function between flash suppression and recoil mitigation modes, providing adaptability without permanently fixing the device to a single function
3Ease of manufacture
If conventional venting apertures are used, then the manufacturing process is simple, but the gas disruption and flame dispersion effectiveness is insufficient
Solution Approach 1:
Different regions of the muzzle device incorporate differently oriented and patterned vent holes tailored to local requirements: transverse vent holes in the body portion for immediate gas diversion, longitudinal vent holes in the forward section for extended gas dispersal, and cooling fins in the rear section for localized heat management. This localized optimization of venting characteristics maximizes gas disruption effectiveness while maintaining manufacturing simplicity
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 design provides improved muzzle flash suppression, recoil mitigation, and cooling of propellant gases, allowing for effective reduction of muzzle rise and enhanced performance in both flash suppression and brake functions.
Implementation Method 1
Muzzle brakes typically utilize one or more slots, vents, holes, and/or baffles to divert and/or redirect the propellant gases as they leave the barrel
Implementation Method 2
The flash suppressor reduces the chances that the individual shooting the firearm will be temporarily blinded in lowlight shooting conditions and/or reduce the degree of muzzle flash visible to others by dispersing or cooling the burning propellant gases
Implementation Method 3
an anti-rotation screw positioned through the screw aperture and threadedly received within at least a portion of the screw recess
