Rotating Gas Flow Control Member for Firearm Impingement Block

Solution Overview

Problem

Current impingement systems in firearms suffer from continuous carbon-laden gas introduction, leading to contaminant buildup and excessive heat, resulting in misfiring, jamming, and increased wear, due to inadequate gas flow control and frequent cleaning needs.

Innovation Solution

An adjustable gas flow control member with calibrated rotational movement, comprising a shaft with longitudinal indentations and a control pin biased by a spring, is integrated into the impingement gas block to precisely control gas flow and prevent contaminant accumulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If gas flow control is implemented using conventional methods (controlling input flow only), then gas flow into the port is controlled, but excessive pressure and heat build-up occur on the impingement system block, and flow blow-back into the barrel increases

Engineering Contradiction:

Improvegas flow controlVSAvoidheat build-up on impingement block

Core Design Contradiction:

Quantity of substanceVSTemperature

Solution Approach 1:

The gas flow control function is segmented into two independent controllable elements: (1) an input flow control aperture that regulates gas entering the gas block, and (2) a diverter member with adjustable aperture that controls gas diversion to the port. This segmentation allows independent optimization of each control point to prevent both excessive heat build-up and flow blow-back into the barrel.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The diverter member acts as an intermediary element positioned within the gas block to intercept and redirect gas flow. By introducing this intermediate control mechanism, the system can manage gas distribution between the port and barrel, preventing direct blow-back while controlling heat-generating pressure build-up on the impingement block.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If fixed gas flow control is used, then simple structure is maintained, but precise control of gas flow diversion is not achieved

Engineering Contradiction:

Improvegas flow control structureVSAvoidprecise gas flow control

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The diverter member is designed as a movable component that can be rotated or adjusted to change the size and orientation of its aperture. This dynamic adjustment capability allows the user to precisely control gas flow diversion in real-time, transforming a static control system into an adaptable one that responds to varying operational requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system enables continuous adjustment of gas flow parameters by varying the diverter member position, which changes the aperture area and flow direction. This parameter control approach allows precise modulation of gas flow characteristics without requiring complex control systems, maintaining mechanical simplicity while achieving operational precision.
