Integrally Suppressed Barrel for Subsonic Velocity Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm suppressors fail to effectively reduce supersonic ammunition velocity to subsonic levels, manage muzzle blast and heat insulation, and often require additional components, leading to bulkiness and operational complexity.
Innovation Solution
An integrally suppressed barrel system with a barrel featuring transverse holes, a gas block assembly, pressure retainer, and a double-walled suppressor housing that reduces supersonic load velocity to subsonic, suppresses muzzle blast, and provides thermal insulation through a double-walled configuration with insulating materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional suppressor designs are used, then muzzle blast suppression is achieved, but supersonic velocity reduction to subsonic levels is not effective
Solution Approach 1:
The patent combines the suppressor and barrel into an integrally suppressed barrel system where the suppressor chambers are formed directly within the barrel structure. This integration allows the barrel to simultaneously serve as both the firing chamber and the suppressor, eliminating the need for separate suppressor components while achieving effective velocity reduction from supersonic to subsonic levels through the integrated chamber design.
Solution Approach 2:
The barrel is segmented into multiple functional chambers including a first chamber for projectile acceleration and second chambers configured as suppressor chambers. This segmentation allows different sections of the barrel to perform different functions - the first chamber maintains supersonic velocity for effective firing while the second chambers reduce velocity to subsonic levels and suppress muzzle blast, thereby achieving both speed control and complexity reduction.
2Object-affected harmful factors
If additional components are added to conventional firearm systems for suppression, then muzzle blast control is improved, but weight and bulkiness increase
Solution Approach 1:
The suppressor functionality is merged directly into the barrel structure through integrally formed suppressor chambers. This eliminates the need for separate suppressor components that would add weight and bulkiness, while still achieving effective muzzle blast control through the integrated chamber design that redirects and dissipates propellant gases.
3Temperature
If thermal insulation components are added to suppressors, then heat protection is improved, but device complexity and weight increase
Solution Approach 1:
The thermal insulation function is merged into the integrally suppressed barrel system through the coordinated design of the suppressor chambers and barrel structure. The integrated chambers naturally manage heat distribution and dissipation, eliminating the need for separate insulation components such as insulated pads or sleeves, thereby achieving heat protection without increasing device complexity.
4Object-generated harmful factors
If conventional suppressor designs are used, then muzzle blast suppression is achieved, but the system requires multiple separate components resulting in bulkiness
Solution Approach 1:
The suppressor and barrel are merged into a single integrally suppressed barrel system where the suppressor chambers are formed directly within the barrel structure. This integration reduces the system to essentially one component rather than multiple separate parts (barrel plus separate suppressor), thereby achieving muzzle blast suppression while eliminating bulkiness and component complexity.

AI summary
An integrally suppressed barrel system for a firearm, the system comprises a barrel having a series of transverse holes and a spiral groove forming machine-type threads of some dimension or specification, a gas block assembly configured to provide integration with the gas cycling system inherent to a firearm, a gas tube configured to protrude back into an upper receiver of the firearm, and a suppressor having a main housing. The main housing of the suppressor includes an inner wall, an outer wall, a series of holes and a base attached to the barrel through machine threads. The suppressor is fixed in a concentric pattern about the bore of the barrel.
