Solution Overview

Problem

Existing muzzle end barrel device coupling systems for firearms are cumbersome and unreliable, failing to effectively address muzzle jump, recoil, blast, and flash, which impact accuracy and safety.

Innovation Solution

A suppressor coupling assembly with a quick attachment/detachment mechanism, featuring a muzzle brake, coupling body, moveable collar, and clamps, that allows for tool-free attachment of suppressors or other devices to the firearm, utilizing a spring-biased moveable collar to secure the suppressor core and reduce muzzle effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If typical muzzle end barrel device coupling assemblies are used, then suppressors can be attached to firearms, but the coupling mechanism becomes cumbersome and unreliable

Engineering Contradiction:
Improvecoupling reliabilityVSAvoidcoupling assembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The coupling assembly is divided into distinct functional components: a coupling body with threaded engagement, a moveable collar for actuation, and clamps for securing. This segmentation allows each component to perform its specific function reliably while keeping the overall design manageable and maintainable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The moveable collar transitions between extended and retracted positions to dynamically control the engagement state. When extended, it actuates the clamps to secure the suppressor; when retracted, it releases the clamps for removal. This dynamic mechanism provides reliable attachment and detachment without complex fastening procedures.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If traditional attachment methods are used, then suppressors can be secured to firearms, but the attachment process requires tools and multiple steps

Engineering Contradiction:
Improveattachment easeVSAvoidattachment time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The coupling assembly is designed to be self-servicing through its spring-biased moveable collar mechanism. The spring automatically maintains the collar in the extended position for engagement, and the threaded coupling body self-actuates the clamps as it is screwed onto the suppressor. This eliminates the need for external tools or multiple manual steps, allowing quick tool-free attachment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The spring is pre-loaded to bias the moveable collar into the extended position before engagement. This preliminary action ensures that the clamps are already positioned to engage with the suppressor flange as soon as the coupling body is threaded on, eliminating the need for separate adjustment or tightening steps during attachment.

Inventive Principle:
Principle #10Preliminary action

3Object-affected harmful factors

If suppressors are attached to reduce muzzle effects, then accuracy and safety improve, but the coupling mechanism may fail under recoil and blast forces

Engineering Contradiction:
Improvemuzzle effects reductionVSAvoidcoupling reliability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The spring-loaded moveable collar acts as a counterbalancing mechanism that maintains constant engagement pressure on the suppressor clamps. The spring force counteracts the tensile loads generated by recoil and blast forces, preventing the coupling from loosening or failing under these harmful conditions while allowing the suppressor to effectively reduce muzzle effects.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The spring mechanism provides beforehand cushioning by maintaining pre-loaded engagement pressure on the clamps before recoil forces occur. This pre-positioning ensures that the coupling is already stressed and ready to withstand the sudden loads of recoil and blast, preventing failure rather than reacting to it after the fact.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
