Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flash suppressors do not effectively cool or disperse propellant gases before they exit the muzzle, leading to inadequate muzzle flash reduction and insufficient surface area at the firearm barrel end.
Innovation Solution
A flash suppressor assembly with a body having a central bore aperture and multiple air channels, a rotatable collar with airflow apertures, and relief cuts on the prongs to increase surface area, enhancing gas cooling and dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If known flash suppressor geometry is used, then the device structure is simple, but the propellant gas cooling and dispersion effectiveness is insufficient
Solution Approach 1:
The flash suppressor body is segmented into multiple functional zones with internal air channels divided into separate inlet and outlet sections. This segmentation allows propellant gases to be cooled by ambient air flowing through the channels, reducing gas temperature while maintaining a relatively simple overall structure.
Solution Approach 2:
The invention transitions from a simple cylindrical geometry to a more complex three-dimensional structure with internal air channels and prongs extending in multiple directions. This dimensional complexity enables effective gas cooling and dispersion pathways without significantly increasing the external footprint of the device.
2Area of stationary object
If known flash suppressor geometry is used, then the manufacturing process is simple, but the surface area for gas cooling is insufficient
Solution Approach 1:
The suppressor includes multiple prongs with relief cuts that segment the gas flow paths and increase the effective surface area for heat exchange. These segmented structures provide extensive cooling surface area while using standard machining operations to manufacture.
Solution Approach 2:
The flash suppressor incorporates a porous-like structure through relief cuts and air channels that create numerous flow paths and increase the effective surface area for gas cooling. This porous architecture enhances heat transfer efficiency while being manufacturable through conventional processes.
3Adaptability or versatility
If a fixed collar design is used, then the device structure is simple, but the adaptability to different shooting conditions is limited
Solution Approach 1:
The collar is designed as a dynamic, rotatable component that can be adjusted between different angular positions relative to the flash suppressor body. This dynamic adjustment allows users to align or misalign collar apertures with air channel outlets, adapting the device to different shooting conditions such as suppressed vs. unsuppressed firearms.
Solution Approach 2:
The rotatable collar mechanism provides multi-functionality by enabling the same flash suppressor assembly to work effectively with both suppressed and unsuppressed firearms. The collar's adjustable positioning creates different flow patterns that adapt to various shooting scenarios, making the device universally applicable.
