Modular Firearm Suppressor with Detachable Baffle Stages

Solution Overview

Problem

Firearm noise and recoil suppressors require a trade-off between weight, length, and sound suppression performance, necessitating a user to choose between shorter, lighter suppressors with reduced performance and longer, heavier ones with superior suppression, lacking a modular solution that offers both configurations in a single device.

Innovation Solution

A modular suppressor design featuring a two-stage configuration with a blast module and two baffle modules, allowing for a shorter single-stage or longer two-stage setup, where the second stage is detachably secured to the first, providing adjustable noise and recoil suppression based on user needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a longer suppressor with more baffles is used, then sound suppression performance is improved, but weight and length increase

Engineering Contradiction:

Improvesound suppression performanceVSAvoidsuppressor weight

Core Design Contradiction:

Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

The suppressor is divided into a first stage with a blast module and first baffle module, and a second stage with a second baffle module that can be detachably secured to the first stage. This segmentation allows users to configure the suppressor in a shorter single-stage mode or a longer two-stage mode, providing flexibility to balance sound suppression performance against weight and length requirements.

3Adaptability or versatility

If a modular suppressor with detachable stages is used, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveconfiguration flexibilityVSAvoidmodular assembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The suppressor is divided into a first stage with a blast module and first baffle module, and a second stage with a second baffle module that can be detachably secured to the first stage. This segmentation allows users to configure the suppressor in a shorter single-stage mode or a longer two-stage mode, providing flexibility to balance sound suppression performance against weight and length requirements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The suppressor employs a dynamic configuration system where the second stage can be detachably secured to or removed from the first stage, allowing the device to adapt its structure based on operational requirements. This dynamic adjustability enables users to optimize the suppressor for different scenarios without being constrained by a fixed design.

AI summary

Provided is a firearm noise suppressor attachable to a firearm barrel. The suppressor includes a first housing attachable to a muzzle end of a firearm barrel, having a forward end first cap, and enclosing a blast chamber adjacent the muzzle end defined rearward of a barrier wall having a first axial passageway therein, a first brake chamber positioned forward of the blast chamber barrier end wall, and a first baffle module having a second axial passageway therethrough that is in axial alignment with a bore of the barrel and a plurality of longitudinally aligned separated baffle units. Each baffle unit includes a plurality of circumferentially spaced, longitudinally extending helically curved chambers with closed longitudinal ends. The helically curved chambers are in fluid communication with the second axial passageway.
