Muzzle Brake Radial Venting Gas Redirection

Solution Overview

Problem

Existing muzzle devices fail to effectively reduce recoil, muzzle flash, and side concussion simultaneously, as they lack methods to expand, cool, and disrupt shock wave formation of propellant gases.

Innovation Solution

A muzzle device with a cylindrical body featuring a coaxial passageway, radial vent holes, and diverging slots or conical nozzles that redirect, expand, and cool propellant gases, disrupting shock wave formation to reduce recoil and muzzle flash, while minimizing side concussion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If conventional muzzle brakes and compensators are used, then some recoil reduction is achieved, but muzzle flash and side concussion are not effectively suppressed

Engineering Contradiction:
Core Design Contradiction:
ForceVSObject-generated harmful factors

Solution Approach 1:

The muzzle device segments the propellant gas flow into multiple paths through radial vent holes distributed around the cylindrical body, directing gases at different angles to simultaneously achieve recoil reduction, flash suppression, and side concussion minimization

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention adds a radial dimension to gas redirection by incorporating radial vent holes that extend outward from the central axis, creating three-dimensional gas distribution patterns that conventional two-dimensional compensators cannot achieve

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Object-generated harmful factors

If small expansion chambers and vent holes are used, then slight flash suppression is achieved, but effective cooling and shock wave disruption are not realized

Engineering Contradiction:
Core Design Contradiction:
Object-generated harmful factorsVSTemperature

Solution Approach 1:

The invention changes the physical parameters of propellant gases by providing sufficient expansion volume and cooling surface area through the cylindrical body design, allowing gases to cool below ignition temperature before atmospheric release

Inventive Principle:

Solution Approach 2:

The cylindrical body acts as an intermediary cooling chamber between the combustion chamber and atmosphere, providing thermal energy transfer surface area that mediates the temperature reduction of propellant gases

Inventive Principle:
Principle #24Intermediary (Mediator)

3Force

If radial vent holes are added to redirect gases, then recoil is reduced, but side concussion increases without slot communication

Engineering Contradiction:
Core Design Contradiction:
ForceVSObject-generated harmful factors

Solution Approach 1:

The slots provide localized communication pathways at specific angular positions around the cylindrical body, allowing controlled gas release in directions that minimize side concussion while maintaining recoil reduction benefits

Inventive Principle:
