Solution Overview

Problem

Existing suppressor attachment methods, such as direct-thread and HUB mounts, suffer from wear and tear, leading to potential detachment and alignment issues, and require frequent tightening, which can be dangerous and cumbersome.

Innovation Solution

A suppressor connector with flexible pawls and outer hoods that allow for quick and secure attachment and detachment, utilizing a bi-directional ratcheting system to prevent unintended separation, featuring a flexible pawl mechanism that bends to engage with engagement teeth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If direct-thread or HUB mount methods are used to attach suppressors, then suppressors can be securely attached to firearms, but wear and tear occur on engagement surfaces leading to potential detachment and alignment issues

Engineering Contradiction:

Improveattachment securityVSAvoidservice life of engagement surfaces

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The suppressor attachment system is divided into separate functional components: a connector with pawls that engage with teeth on the muzzle device. This segmentation allows the engagement surfaces (teeth and pawls) to be replaceable and wear-resistant, while the main suppressor and firearm remain unaffected by wear

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pawls are designed to be flexible rather than rigid, allowing them to dynamically adjust during attachment and detachment. The flexible pawls can bend to accommodate minor misalignments and maintain consistent engagement force, reducing wear on both the pawls and engagement teeth

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If suppressors are permanently fixed to the barrel, then alignment is maintained, but suppressors cannot be removed for maintenance or when not needed

Engineering Contradiction:

Improvealignment stabilityVSAvoidremovability of suppressor

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The connector is pre-installed on the firearm muzzle with engagement teeth already in position. When attaching a suppressor, the pawls are already configured to engage with these teeth, ensuring immediate and accurate alignment without requiring adjustment during the attachment process

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If suppressors are frequently attached and detached, then adaptability is improved, but wear on engagement surfaces increases leading to detachment risks

Engineering Contradiction:

Improvefrequency of attachment/detachmentVSAvoidattachment security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The flexible pawls automatically self-adjust during each attachment cycle, bending to match the engagement teeth position and maintaining optimal engagement force. This self-adjusting mechanism compensates for wear over time, maintaining reliable attachment even after frequent use

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The engagement mechanism uses flexible pawls that change their physical state (bending angle, contact force) during engagement. This dynamic parameter adjustment allows the system to accommodate wear while maintaining secure attachment, as the pawls can deform to maintain proper engagement geometry

Inventive Principle:

Principle #35Parameter changes

4Reliability

If engagement teeth are used to prevent suppressor separation, then attachment security is improved, but alignment may shift during repeated tightening

Engineering Contradiction:

Improveprevention of unintended separationVSAvoidalignment precision

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The engagement teeth are designed with asymmetric profiles that engage unidirectionally with the pawls. This asymmetric design allows the pawls to prevent separation in the firing direction while accommodating minor alignment variations, maintaining both security and precision

Inventive Principle:

Principle #4Asymmetry

AI summary

A suppressor connector has distal end threads operable to couple the suppressor connector to a suppressor device and proximal end threads operable to couple to a muzzle of a firearm. At least one flexible pawl is coupled to the suppressor connector and has a free-floating proximal end that terminates beyond the proximal thread end of the set of proximal end threads of the suppressor connector and has an engagement face on the free-floating proximal end. At least one outer hood has a distal end coupled to the suppressor connector proximate to the distal end of the flexible pawl and a free-floating proximal end that at least partially covers the free-floating proximal end of the flexible pawl and that extends beyond and substantially parallel to the free-floating proximal end of the flexible pawl.
