Underwater Muzzle Suppressor with Segmented Cylinders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underwater firearms lack a muzzle suppressor system that effectively directs blast pressure away from the user, posing safety concerns and exposure risks to the marine environment.
Innovation Solution
An underwater muzzle suppressor system comprising an interior and exterior cylinder with axial slots, disks, and elastomeric O-rings, creating a cylindrical chamber to redirect blast pressure, allowing the bullet and blast energy to exit at various angles, thereby reducing user concussion and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional underwater firearms are used, then the firearm can function underwater, but the blast pressure directly impacts the user causing concussion and environmental exposure
Solution Approach 1:
The suppressor is divided into multiple cylindrical sections (first cylinder, second cylinder, third cylinder) with axial slots at different positions. Each section segments the blast pathway, directing gases through controlled openings away from the user in multiple directions rather than as a single concentrated force.
Solution Approach 2:
The axial slots are positioned at different angular orientations around the cylindrical chambers. This distributes the blast pressure discharge in multiple spatial dimensions (360-degree dispersion) rather than linearly, reducing the concentrated impact on the user while maintaining underwater functionality.
2Reliability
If a muzzle suppressor system is added to redirect blast pressure, then user safety improves, but the device complexity increases
Solution Approach 1:
The suppressor employs nested cylindrical structures where the first cylinder contains the second cylinder, which contains the third cylinder. Each nested cylinder has its own axial slots and chamber space, creating a compact multi-functional structure that redirects blast pressure through multiple layers without requiring excessive external space.
Solution Approach 2:
The suppressor system serves multiple functions: it redirects blast pressure away from the user, disperses propellant gases into the water environment, and can function as a flash hider or suppressor on land. The same cylindrical structure with axial slots achieves both underwater safety and terrestrial firearm suppression functions.
3Object-affected harmful factors
If axial slots are formed in cylinders to disperse gases, then environmental exposure is reduced, but manufacturing precision requirements increase
Solution Approach 1:
Instead of forming complex three-dimensional gas dispersion patterns, the design segments the dispersion function into multiple simple axial slots positioned at different heights and angular orientations on each cylinder. Each slot is a straightforward linear opening that can be manufactured with standard precision tools.
Solution Approach 2:
Each cylinder has axial slots positioned at specific local positions (different heights and angular orientations) optimized for its function in the nested structure. The first cylinder slots differ from the second, which differ from the third, allowing each local region to contribute specifically to overall gas dispersion without requiring uniform precision across the entire suppressor.

AI summary
An underwater muzzle suppressor system for directing away from a user the blast pressure of a firearm has an interior cylinder with a rearward end and a forward end with primary axial slots formed in the interior cylinder adjacent to the rearward end. An exterior cylinder has a rearward end and a forward end with secondary axial slots formed in the exterior cylinder adjacent to the forward end. A cylindrical chamber is created between the interior cylinder and the exterior cylinder. A rearward disk is received over the rearward end of the interior cylinder. The rearward disk is coupled to the rearward end of the exterior cylinder. A forward disk receives the forward end of the interior cylinder. The forward disk is coupled to the forward end of the exterior cylinder. A plurality of axial holes are in the forward disk.
