Shotgun Silencer With Longitudinal Elevations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional silencers for shotguns are inefficient in noise suppression due to the multi-part nature of shotgun shells, which complicates the design and results in poor damping performance compared to single-projectile firearms, as they lack the necessary clearance between the projectile and the silencer's bore.
Innovation Solution
A modular silencer design featuring an outer housing with a main part and end parts, an inner hollow body with axial longitudinal elevations and throughgoing openings, and a threaded connection for secure attachment to a shotgun barrel, providing a stable structure for noise reduction and improved projectile alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the clearance between the throughgoing bore and the projectile is reduced to improve noise suppression, then noise suppression is improved, but the risk of projectile contact with the bore increases
Solution Approach 1:
The shotgun shell is divided into multiple segments (shots separated by wads and cups) that can be individually contained and directed through the silencer's segmented internal structure, allowing each segment to be managed separately to prevent contact while maintaining noise suppression
2Device complexity
If conventional silencer designs with baffles are used for shotguns, then the structure is simple, but noise suppression is poor due to lack of safe enclosure for multi-part projectiles
Solution Approach 1:
The silencer employs a nested structure where an inner hollow body with throughgoing openings is positioned within an outer housing, creating concentric containment zones that safely enclose multi-part shotgun projectiles while maintaining a compact overall structure
Solution Approach 2:
The invention transitions from conventional two-dimensional baffle designs to a three-dimensional nested hollow body structure with axial throughgoing openings, creating additional spatial dimensions for projectile containment and gas flow management that improve noise suppression
3Object-affected harmful factors
If punched cylinders are used to enclose the shot column with turbulence-inducing materials, then noise suppression is improved, but the design is complex and not suitable for supersonic shotgun projectiles
Solution Approach 1:
The silencer utilizes pneumatic principles by allowing exhaust gases to flow axially through the hollow body's bore and openings, using gas pressure and flow dynamics to manage the multi-part projectile separation and containment without requiring complex mechanical turbulence-inducing structures
