Integrated Suppressor Assembly Combining Diffuser and Sound Baffles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms face challenges in reducing audible and visible signatures while maintaining ballistic performance, with existing suppressors being inefficient due to the need for separate diffusers and sound suppressors that require small, inefficient flow diffusers.
Innovation Solution
A suppressor assembly with a diffusor assembly that combines a diffusor portion and a signature-reduction portion in a single unit, featuring a cylindrical body with baffles that create a sinuous flow path to mix propellant gases, reducing sound and flash effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate diffusers and sound suppressors are used, then flash suppression and sound suppression are achieved, but device complexity increases and efficiency decreases
Solution Approach 1:
The patent combines the diffuser and sound suppressor into a single integrated suppressor assembly. The suppressor body includes both diffuser baffles for flash reduction and sound suppressor baffles for noise attenuation, eliminating the need for separate components while maintaining both functions simultaneously.
Solution Approach 2:
The suppressor assembly serves multiple functions within a single device: it acts as both a diffuser for flash suppression and a sound suppressor for noise reduction. The integrated design allows one component to perform multiple roles that previously required separate accessories.
2Object-affected harmful factors
If small flow diffusers are used, then flash suppression is achieved, but gas flow restriction increases and ballistic performance decreases
Solution Approach 1:
The diffuser baffles are positioned and sized to provide localized flash suppression only where needed, rather than completely blocking the gas flow path. The baffles allow propellant gases to pass through while intercepting the flash-producing portion of the expansion, maintaining gas flow efficiency while achieving flash reduction.
3Object-generated harmful factors
If traditional suppressor design is used, then sound suppression is achieved, but visible signature reduction is insufficient
Solution Approach 1:
The suppressor integrates both sound suppression baffles and flash suppression diffuser baffles in a single assembly. This combination allows the device to simultaneously reduce both audible report and visible signature, addressing both harmful factors that traditional single-function suppressors could not effectively manage.

AI summary
A suppressor assembly for a firearm includes a diffusor assembly with a body extending along a central axis. At least one diffusor baffle extends across an inside of the body in a direction transverse to the central axis. The diffusor baffle defines a diffusor central opening and a plurality of outer diffusor openings positioned radially outside the diffusor central opening. Signature-reduction baffles include a first baffle portion that extends across the inside of the body and that defines a central baffle opening and a baffle port positioned radially outside of the central baffle opening. A second baffle portion is connected to the first baffle portion opposite the baffle port and radially outside of the central baffle opening. The second baffle portion extends at an angle to the body sidewall.
