Silencer Muzzle Brake Screw Connection

Solution Overview

Problem

Existing firearms with muzzle brakes cannot be directly connected to silencers, requiring disassembly of the muzzle brake for silencer mounting, which is not feasible or possible in many cases.

Innovation Solution

A screw connection is established between the muzzle brake and silencer, with the muzzle brake's annular base featuring an internal thread that cooperates with the silencer's external thread, ensuring tilt-free guidance and fixation, and allowing explosion gases to be directed into expansion chambers for effective silencing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If a muzzle brake is fixed to the barrel, then recoil reduction is achieved, but silencer mounting becomes impossible without disassembly

Engineering Contradiction:
Core Design Contradiction:
ForceVSEase of operation

Solution Approach 1:

The muzzle brake assembly is segmented into a barrel-mounted portion and a silencer-compatible portion, allowing the silencer to be attached to the muzzle brake's front end without disassembling the barrel connection. This segmentation enables both recoil reduction and silencer mounting to coexist.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The silencer is nested onto the front end of the muzzle brake, creating a layered configuration where the silencer encompasses the muzzle brake's gas outlet. This nesting allows the silencer to be mounted while the muzzle brake remains fixed to the barrel, resolving the contradiction between maintaining muzzle brake functionality and enabling silencer attachment.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If the muzzle brake is disassembled for silencer mounting, then silencer attachment becomes possible, but assembly complexity and time increase

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The muzzle brake is designed with a universal front end configuration that serves dual purposes: maintaining its gas deflection function for recoil reduction and providing a standardized mounting interface for silencers. This multi-functionality eliminates the need for disassembly while enabling silencer attachment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

An intermediary mounting structure is introduced at the front end of the muzzle brake, serving as a mediator between the barrel-mounted muzzle brake and the silencer. This intermediary component enables direct attachment without requiring disassembly of the muzzle brake's barrel connection, simplifying the overall assembly process.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If a screw connection is implemented between muzzle brake and silencer, then direct fixation is enabled, but manufacturing precision requirements increase

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The screw connection parameters (thread pitch, diameter, length) are optimized to balance ease of assembly with manufacturing precision requirements. By carefully selecting these parameters, the design achieves direct fixation capability while keeping precision requirements within standard manufacturing capabilities.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The screw connection is designed to be self-aligning and self-securing, where the threaded structure automatically guides and secures the silencer to the muzzle brake without requiring complex alignment procedures. This self-service characteristic reduces the impact of manufacturing tolerances on assembly difficulty.

Inventive Principle:
Principle #25Self-service

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

Enables the first-time direct fixation of a muzzle brake within a silencer via a screw connection, providing effective sound suppression and reduced muzzle flash without disassembling the muzzle brake, enhancing usability and performance during night missions.

Implementation Method 1

The silencer exclusively reduces the sound emission, which emanates during a gunshot from the highly pressurized gases expanding explosively from the muzzle

Methodology Applied
Scientific EffectSound suppression: Acoustic Absorption

Implementation Method 2

They are deflected perpendicular or even slightly bent backwards by the deflection plates, and thereby transfer a part of their energy to the muzzle brake, and thereby to the barrel

Methodology Applied
Scientific EffectGas deflection: Fluid Spray

Implementation Method 3

They are deflected perpendicular or even slightly bent backwards by the deflection plates, and thereby transfer a part of their energy to the muzzle brake, and thereby to the barrel. The energy of the combustion gases acting in the shooting direction, due to the collision with the muzzle brake, counteracts to the blowback directed backwards and reduces the latter

Methodology Applied
Scientific EffectEnergy transfer through collision: Impact Force

AI summary

A silencer for a firearm, in particular, an assault rifle or another long gun, is provided. The silencer can be fitted onto a barrel of the firearm, wherein a muzzle brake is fixed to the barrel and wherein the muzzle brake can be fixed to the silencer by a releaseable connection, such as a screw connection.
