Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional muzzle brakes have fixed venting directions and volumes, limiting user control over recoil management during firearm discharge.

Innovation Solution

A tunable muzzle brake with adjustable ports and baffles allows users to direct and modulate propellant gas venting, enabling customizable recoil control by opening or closing ports with set screws.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional fixed slots, vents, and holes are used in muzzle brakes, then manufacturing simplicity and durability are improved, but user control over recoil management and adaptability to different shooting conditions deteriorates

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoiduser control over recoil management

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent implements adjustable ports with movable plugs or sliders that allow users to dynamically change the venting configuration. The ports can be opened, closed, or partially blocked to adjust gas venting direction and volume, transforming a static brake into a dynamic system that adapts to different recoil management needs while maintaining a relatively simple overall structure

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The brake body is divided into multiple independent port sections, each with its own adjustment mechanism. This segmentation allows users to control individual ports or groups of ports separately, providing fine-grained control over gas venting patterns without requiring complete redesign of the entire brake structure

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple adjustable ports and baffles are added to enable tunable gas venting, then user control and adaptability are improved, but device complexity increases

Engineering Contradiction:

Improvecustomizable recoil controlVSAvoidnumber of adjustable components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustable ports serve multiple functions: they control gas venting direction, regulate gas flow volume, and can be configured for different shooting scenarios. The same port structure handles both directional control and flow regulation, reducing the need for separate specialized components for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The adjustment mechanisms for multiple ports are integrated into a unified brake body structure. The plugs or sliders for different ports can be adjusted independently but are part of a single cohesive device, allowing complex recoil management capabilities while maintaining a compact form factor without requiring entirely separate adjustment systems for each port

Inventive Principle:

Principle #5Merging (Combining)

3Device complexity

If fixed venting directions are used in traditional brakes, then structural simplicity is improved, but ability to accommodate varying cartridge pressures and shooting techniques deteriorates

Engineering Contradiction:

Improvestructural simplicityVSAvoidaccommodation of varying conditions

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The brake transitions from fixed venting directions to dynamically adjustable directions through movable plugs or sliders in each port. Users can reposition these components to change the angle and orientation of gas venting, allowing the same brake structure to adapt to different cartridge pressures and shooting techniques without requiring multiple specialized brakes

Inventive Principle:

Principle #15Dynamics

AI summary

A muzzle brake (i.e., muzzle brake, suppressor, or compensator) directs air through ports in a top of the muzzle brake. Each pair of ports, left and right, has a corresponding baffle to which they are adjacent and form a recess in the rear face of. Each port is between 15 and 30 degrees from top center, and each port angles forward between 15 and 30 degrees. Each port is threaded such that a user may shut the port off with a set screw. Each baffle has a top tooth and a bottom tooth which direct gases from the muzzle of the firearm laterally and into the pair of ports associated with the baffle. The brake may also have lateral vents to disperse the excess gases received from the muzzle.
