Firearm Sound Suppressor Baffle with Asymmetric Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm sound suppressors are limited in their ability to effectively reduce sound levels across various projectile calibers, require complex disassembly for cleaning, and often need specialized tools, leading to potential misalignment issues during reassembly.
Innovation Solution
A baffle design with a central bore and peripheral grooves and channels on both faces, allowing for easy insertion and orientation, forming a baffle stack that can accommodate different calibers and simplify cleaning by allowing either face to be inserted first, with adjustable baffle and spacer configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional baffles with various shapes and profiles are used to disperse burning gases, then sound level reduction is achieved, but the suppressor is limited to a narrow range of projectile calibers
Solution Approach 1:
The baffle is designed with a central bore and grooves that can accommodate multiple projectile calibers, allowing a single suppressor to function across a range of calibers rather than being limited to one specific size
2Ease of manufacture
If conventional suppressors are designed with fixed baffle configurations, then manufacturing is simplified, but cleaning requires complex disassembly and specialized tools
Solution Approach 1:
The suppressor is divided into modular sections with baffles that can be independently removed and cleaned, allowing maintenance without complete disassembly of the entire device
3Ease of operation
If conventional suppressors use fixed and oriented baffle arrangements, then assembly is straightforward, but reassembly requires careful attention to order and orientation
Solution Approach 1:
The baffle design incorporates asymmetric features such as angled surfaces and positioned grooves that provide self-alignment during assembly, ensuring correct orientation without requiring the user to remember specific arrangements
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 baffle design effectively reduces sound levels by dispersing and absorbing heat and kinetic energy from pressurized gases, is adaptable to various calibers, and allows for easy assembly and disassembly without specialized tools, enhancing user convenience and performance.
Implementation Method 1
The baffle can be used to redirect and slow the release of pressurized gases... The redirection and slowing of the velocity of escaping gas can also lower the speed to a subsonic level
Implementation Method 2
The delay in the release of the gas allows for the gas to partially cool thereby reducing the volume of gas released

AI summary
A baffle for use in a firearm sound suppressor is provided. The baffle defines a central bore extending from a first face of the baffle to a second face and sized to allow a projectile fired from a firearm to freely pass along a longitudinal axis of the baffle. A plurality of grooves are defined in the first face and a plurality of channels are defined in the second face. Each groove begins adjacent to or near the peripheral wall and extends from the first face towards the second face and the central bore along a groove axis and each channel begins adjacent to or near the peripheral wall and extends s from the second face towards the first face and the central bore along a channel axis. Each groove of the first face can be substantially aligned with a channel of the second face. The baffle can be one of a plurality of baffles in a baffle stack.
