Firearm Muzzle Attachment System for Noise Suppressor

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems for attaching and removing noise suppressors from firearms are not easily removable with one hand and do not provide secure attachment or multi-point indexing, which affects the point of impact of discharged projectiles.

Innovation Solution

A noise suppressor system featuring a flash suppressor with external annular serrated locking surfaces and multi-start threads, and a noise suppressor with internal multi-start threads and a spring-loaded locking latch, allowing for secure attachment and single-handed removal, as well as adjustable orientation to affect the point of impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional attachment system is used, then the noise suppressor is securely attached to the firearm, but it cannot be easily removed with one hand

Engineering Contradiction:

Improveease of removalVSAvoidsecure attachment

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The attachment system is divided into separate functional components: a quick-release button mechanism for easy one-handed removal, and a threaded connection system for secure attachment. This segmentation allows each component to specialize in its function without compromise

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A threaded adapter or interface mechanism serves as an intermediary between the quick-release button system and the threaded connection, enabling both easy removal and secure attachment through the same interface

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a fixed attachment system is used, then the attachment is simple, but the point of impact cannot be adjusted

Engineering Contradiction:

Improveadjustability of point of impactVSAvoidattachment system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system adds rotational orientation as an additional degree of freedom to the attachment. The noise suppressor can be rotated to different angular positions (e.g., 0°, 90°, 180°, 270°) while maintaining secure attachment, allowing point of impact adjustment without complicating the attachment mechanism

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The attachment system serves multiple functions: secure mounting, easy removal, and angular positioning for point of impact adjustment. This multi-functionality is achieved through a unified threaded interface that accommodates both attachment and orientation adjustments

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If a simple attachment system is used, then the device complexity is low, but unintentional rotation occurs due to vibrations

Engineering Contradiction:

Improveprevention of unintentional rotationVSAvoidattachment system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The quick-release button mechanism uses asymmetric positioning and engagement features that prevent rotational movement while maintaining simple operation. The button engages in a specific orientation that locks the noise suppressor against rotational forces from vibrations

Inventive Principle:

Principle #4Asymmetry

AI summary

An apparatus and method for easily, quickly and reliably attaching a noise suppressor or other auxiliary device to the muzzle end of a firearm barrel and for easily, quickly and reliably removing the noise suppressor or other auxiliary device there from. My invention also provides for adjusting the host firearms point of impact by changing the orientation of the noise suppressor in relation to the host firearms bore.
