Solution Overview

Problem

Existing flash suppressors for firearms often create undesirable ringing sounds due to tine resonance and have length variations that complicate attachment of other components and increase the risk of debris entanglement and uneven impact absorption.

Innovation Solution

A flash suppressor with helically oriented tines of equal mass, varying cut lengths and widths to prevent ringing, and grooves on the outer surface to reduce weight, ensuring balanced and easy attachment of other firearm components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If tines are used to disperse propellant gases and reduce muzzle flash, then muzzle flash is suppressed, but the high-pressure gases cause the tines to resonate and create an undesirable ringing sound

Engineering Contradiction:
Improvemuzzle flashVSAvoidringing sound
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by varying the dimensions of individual tines to achieve uniform mass distribution. Each tine has different length and width dimensions, but these variations are specifically designed so that all tines have substantially equal mass. This prevents resonant ringing while maintaining effective flash suppression, as the equal mass tines respond uniformly to gas pressure without creating harmful resonance frequencies.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes physical parameters of the tines by varying their length and width dimensions. Instead of using uniform tines, the invention specifies that tines should have different dimensions but equal mass. This parameter variation approach eliminates the ringing problem caused by resonance while preserving the flash suppression function.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If tines of varying length are used in flash hiders, then muzzle flash suppression is achieved, but it creates difficulties in attaching other firearm components and increases the risk of debris entanglement

Engineering Contradiction:
Improvemuzzle flashVSAvoidattachment of firearm components
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent applies local quality by allowing individual tines to have different length and width dimensions while maintaining equal mass. This localized variation in dimensions optimizes flash suppression performance while the equal mass characteristic ensures uniform response to gas pressure, preventing resonance and simplifying the attachment of other firearm components.

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If longer tines are used to improve flash suppression, then muzzle flash is better reduced, but the longer tine catches on debris and absorbs the majority of impact if the firearm is dropped

Engineering Contradiction:
Improvemuzzle flashVSAvoidresistance to debris entanglement and impact
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent applies local quality by varying the dimensions of individual tines to achieve uniform mass distribution. Each tine has different length and width, but these variations are specifically designed so that all tines have substantially equal mass. This prevents any single tine from being excessively long and catching on debris, while the equal mass distribution ensures uniform impact absorption across all tines.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes the physical parameters of the tines by varying length and width dimensions while maintaining equal mass. This parameter optimization prevents excessive length that would cause debris entanglement, while ensuring all tines have equal mass to distribute impact forces uniformly, improving reliability.

Inventive Principle:
Principle #35Parameter changes
