Solution Overview

Problem

Conventional flash suppressors attached to the muzzle end of a firearm barrel do not effectively reduce muzzle jump, recoil, and flash, as they do not integrate with the firearm's slide to manage propellant gases efficiently.

Innovation Solution

A firearm slide with an integrated flash hider, featuring a bore with elongated axial slots and radial holes, and internal ribs, designed to slow, expand, and cool propellant gases by accommodating the barrel's movement and spin, thereby reducing muzzle flash, recoil, and jump.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a conventional flash suppressor is attached to the muzzle end of the barrel, then the flash is reduced, but the muzzle jump, recoil, and flash are not effectively reduced due to lack of integration with the slide

Engineering Contradiction:

Improvemuzzle flashVSAvoideffectiveness in reducing muzzle jump and recoil

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The flash hider is integrated into the firearm slide as a single unified component rather than being a separate attachment. The slide assembly includes the flash hider with bore, ports, and internal ribs formed as one piece with the slide, creating a unified gas management system that addresses muzzle flash, recoil, and jump simultaneously through coordinated internal geometry.

Inventive Principle:

Principle #5Merging (Combining)

2Object-affected harmful factors

If a flash suppressor is attached to the muzzle, then flash is reduced, but propellant gases are not efficiently managed due to lack of integration with barrel movement and spin

Engineering Contradiction:

Improvevisible flashVSAvoidpropellant gas management

Core Design Contradiction:

Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The flash hider internal geometry is designed to dynamically accommodate the spinning and moving barrel during firing. The elongated axial slots and radial holes are configured to work with the rotational motion of the barrel, allowing the gas management system to adapt to the dynamic conditions of barrel movement and spin while maintaining effective gas control.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The flash hider incorporates multiple segmented gas flow paths including elongated axial slots and radial holes that divide and redirect propellant gases through different routes. This segmentation of gas flow allows for more effective management of hot gases by distributing them across multiple exit paths and cooling surfaces.

Inventive Principle:

Principle #1Segmentation

3Object-affected harmful factors

If conventional flash suppressors are used, then flash is reduced, but device complexity increases without integration into the slide

Engineering Contradiction:

Improvemuzzle flashVSAvoidnumber of separate components

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The flash hider is merged with the slide to form a single integrated component, reducing the total number of separate parts. The bore, ports, and internal ribs are all formed as one piece with the slide, eliminating the need for separate flash suppressor attachments and simplifying the overall firearm assembly.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated flash hider performs multiple functions simultaneously: it reduces muzzle flash, manages propellant gases, accommodates barrel movement, and works with barrel spin. This multi-functionality is achieved through the unified design that combines gas redirection paths, cooling surfaces, and dynamic accommodation features within a single component structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The integrated flash hider within the firearm slide effectively reduces muzzle flash, recoil, and jump by managing propellant gases, providing improved control and visibility during firing.

Implementation Method 1

Flash suppressors reduce, or in some cases eliminate, the flash by rapidly cooling the gases as they leave the muzzle of the barrel

Implementation Method 2

The flash hider may include a bore forming an internal cavity and a plurality of ports in communication with the bore. The plurality of ports may comprise elongated axial slots, elongated radial holes, or a combination thereof
