Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current sound suppression technologies for firearms are inadequate in maintaining low acoustic noise levels over a long service life with minimal maintenance, as they often rely on fluids that need periodic replacement and are not effective in concealing the location of snipers from terrorists, who can use acoustic noise and particulate discharge to locate shooters.

Innovation Solution

An energy capture and control device with a central chamber and an off-axis chamber featuring a serpentine fluid pathway and deflectors to dissipate sound and shock waves, using materials like titanium and optional energy absorbent materials, which reduces acoustic noise and particulate discharge without the need for frequent fluid replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If sound absorbing fluid (oil or water) is used in the suppressor, then acoustic suppression performance is improved, but maintenance requirements increase due to periodic fluid replacement and vaporization

Engineering Contradiction:

Improveacoustic suppression performanceVSAvoidservice life with minimal maintenance

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent removes the sound-absorbing fluid (oil or water) from the suppressor system entirely. Instead, it uses a dry baffle system with vortex-inducing structures that dissipate acoustic energy through turbulence and vortex formation, eliminating the need for fluid replacement and avoiding vaporization issues while maintaining effective sound suppression

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the fluid-based acoustic absorption mechanism with a solid mechanical structure consisting of baffles and vortex-inducing elements. The acoustic energy is dissipated through mechanical turbulence and vortex formation in the gas flow, substituting the chemical/physical absorption mechanism of fluids with a purely mechanical energy dissipation system

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If internal baffles with vortices and expansion chambers are used, then sound suppression is achieved, but device complexity increases

Engineering Contradiction:

Improvesound suppressionVSAvoidstructural complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The suppressor is divided into multiple discrete baffle elements arranged in series, each creating localized vortices and pressure drops. This segmentation allows the acoustic energy to be dissipated in multiple small stages rather than requiring a single complex expansion chamber, simplifying the overall structure while maintaining effectiveness

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The baffles are designed with curved surfaces that efficiently generate vortex flows. The curved geometry naturally induces rotational motion in the gas stream, creating turbulence and eddies that dissipate acoustic energy without requiring complex internal geometries or multiple expansion chambers

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Object-affected harmful factors

If high degree sound reduction is achieved, then acoustic suppression performance is improved, but useful lifespan decreases

Engineering Contradiction:

Improvesound reduction levelVSAvoiduseful lifespan

Core Design Contradiction:

Object-affected harmful factorsVSDuration of action of stationary object

Solution Approach 1:

The patent employs a simple, robust baffle structure made from durable materials that can withstand high-temperature and high-pressure conditions. The design prioritizes structural simplicity and material durability over complex mechanisms, enabling the suppressor to maintain its sound reduction performance throughout a long service life without degradation

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
