Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current suppressor designs trap pressure in the initial chamber, causing back pressure, mechanical failures, and accuracy issues due to gas turbulence and debris blown back into the operator's face.

Innovation Solution

A firearm suppressor design featuring fluid redirectors with vanes in clockwise or counterclockwise configurations, a baffle sleeve with interdigitated baffles, and an alignment tube to redirect and equalize gas pressure, reducing back pressure and turbulence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the basic baffle and chamber design is used to trap expanding gases, then gas containment is improved, but back pressure increases causing firearm malfunction and mechanical failures

Engineering Contradiction:

Improvegas containmentVSAvoidback pressure

Core Design Contradiction:

ReliabilityVSStress or pressure

Solution Approach 1:

The suppressor divides the gas containment into multiple sequential chambers rather than a single chamber. Each chamber has its own baffle assembly that processes gas in stages, preventing pressure buildup in one location while maintaining effective gas containment throughout the system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a longitudinal dimension to gas flow by creating multiple chambers arranged along the length of the suppressor. Gas flows sequentially through each chamber in the longitudinal direction, allowing pressure to be distributed across multiple locations rather than concentrated in a single chamber.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If the basic baffle design traps pressure in the initial chamber, then gas containment is improved, but gas and debris are blown back into the operator's face

Engineering Contradiction:

Improvegas containmentVSAvoiddebris blown back

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The suppressor segments the gas flow path into multiple chambers with individual baffle assemblies. This segmentation prevents uncontrolled gas and debris ejection toward the operator by distributing the containment function across multiple staged chambers, each managing gas flow at a different location.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediate baffle assemblies between the barrel and the final exhaust. These intermediate baffles act as mediators that progressively manage and redirect gas flow, preventing direct ejection of gas and debris toward the operator while maintaining effective containment.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If the basic design uses small holes for gas exit, then gas containment is improved, but turbulence and accuracy issues occur

Engineering Contradiction:

Improvegas containmentVSAvoidaccuracy

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The suppressor segments the gas exit into multiple controlled openings distributed across different chambers and baffles. This segmentation allows for more controlled gas release patterns that reduce turbulence compared to a single concentrated opening, while maintaining effective gas containment through the multi-chamber structure.

Inventive Principle:

Principle #1Segmentation

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

The design effectively reduces back pressure, minimizes mechanical failures, and enhances accuracy by balancing gas flow and cooling, preventing debris from reaching the operator.
