Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Suppressors increase back pressure in the barrel, affecting firearm operation and reducing service life, while existing designs do not effectively manage noise and muzzle flash.

Innovation Solution

A progressive rotation baffle stack configuration with varying twist rates and cross-sectional geometries in multiple sections, including a blast chamber, each section with a unique twist rate and aperture size, is used to manage gas flow and reduce back pressure.

1Object-affected harmful factors

If traditional baffle configurations are used in suppressors, then noise and muzzle flash are reduced, but back pressure in the barrel increases

Engineering Contradiction:

Improvenoise and muzzle flashVSAvoidback pressure

Core Design Contradiction:

Object-affected harmful factorsVSStress or pressure

Solution Approach 1:

The suppressor is divided into multiple distinct sections (first section with 45-degree twist, second section with 30-degree twist, third section with 15-degree twist), each with progressively different twist rates. This segmentation allows the gas flow to be managed in stages, reducing overall back pressure while maintaining noise and flash suppression effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The baffle twist rates are made progressive rather than uniform, creating a dynamic flow management system where the twist rate changes along the length of the suppressor. This dynamic approach optimizes gas flow at different stages of expansion, reducing back pressure compared to static uniform twist designs.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If suppressors are designed to reduce noise and muzzle flash, then firearm service life is reduced due to increased back pressure

Engineering Contradiction:

Improvenoise and muzzle flashVSAvoidservice life

Core Design Contradiction:

Object-affected harmful factorsVSDuration of action of stationary object

Solution Approach 1:

By segmenting the suppressor into multiple sections with progressively varying twist rates, the design reduces overall back pressure on the firearm system. This segmentation allows for more efficient gas flow management that decreases the cumulative stress on firearm components, thereby extending service life while maintaining suppressor effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The twist rate parameter is changed progressively through different sections (45 degrees, then 30 degrees, then 15 degrees) rather than maintaining a constant value. This parameter variation optimizes the balance between noise suppression and back pressure management, reducing the harmful effects on firearm service life.

3Ease of manufacture

If uniform twist rate baffles are used, then manufacturing is simpler, but gas flow management is less effective

Engineering Contradiction:

Improvebaffle manufacturingVSAvoidgas flow management efficiency

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The suppressor is divided into multiple sections, each with uniform twist rates that are easier to manufacture individually. The first section uses 45-degree twists, the second uses 30-degree twists, and the third uses 15-degree twists. This segmentation makes manufacturing more feasible compared to a single complex variable twist design, while still achieving superior gas flow management through the progressive twist progression.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different sections of the suppressor have different twist rate qualities optimized for their specific locations in the gas flow path. The first section has higher twist (45 degrees) for initial gas redirection, the second section has medium twist (30 degrees) for continued expansion management, and the third section has lower twist (15 degrees) for final flow stabilization. This local optimization improves overall gas flow management efficiency.
