Solution Overview

Problem

Existing firearm gas flow regulation systems lack the ability to precisely adjust gas flow across a continuous range of preset positions with a nonlinear gradient and often direct exhaust gas back towards the operator, leading to unreliable performance and potential health hazards.

Innovation Solution

A low-profile gas block system with a gas plug regulator that allows nonlinear adjustment of gas flow through varying segment areas and geometries, combined with detents and a position selector for precise positioning, and a design that vents discharge gas away from the operator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing gas flow regulation systems use a small number of presets with linear gradient adjustment, then the device complexity is reduced, but the gas flow control precision and adaptability are insufficient

Engineering Contradiction:
Improvegas flow control precisionVSAvoidgas flow regulation mechanism complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The gas plug is made rotatable within the gas plug bore, transforming the static gas flow regulation into a dynamic system. By rotating the gas plug, the alignment between the regulator portion opening and the gas port changes continuously, enabling precise nonlinear adjustment of gas flow across a wide range without requiring multiple discrete preset positions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the geometric parameter (angular orientation) of the gas plug regulator portion relative to the gas port. This parameter change creates a nonlinear gradient in gas flow restriction, allowing the same mechanical structure to provide both fine adjustment at low flow settings and coarse adjustment at high flow settings.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If existing systems direct exhaust gas through the gas block, then the gas flow system is simplified, but discharge gas is reflected back towards the operator causing health hazards

Engineering Contradiction:
Improveoperator exposure to discharge gasVSAvoidgas block structure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The gas block internal structure is segmented into separate channels: one for directing gas flow away from the operator and another for venting exhaust gas. The gas block includes a first channel that directs discharge gas away from the operator and a second channel that vents exhaust gas from the piston, preventing harmful gas reflection while maintaining structural organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The gas block acts as an intermediary component that intercepts discharge gas before it can reflect back towards the operator. It provides a controlled pathway that redirects the gas flow in a safe direction and separately manages exhaust venting, thereby mediating between the barrel and the operator environment.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the gas block is made larger to accommodate traditional gas flow regulation components, then the gas flow control capability is improved, but the hand guard design is compromised and accessories cannot be installed

Engineering Contradiction:
Improveaccessory installation capabilityVSAvoidgas flow regulation capability
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The gas plug regulator portion is nested within the gas plug, which itself is inserted into the gas plug bore of the gas block. This nested arrangement allows the regulation mechanism to be compact, enabling the gas block to maintain a low profile that fits under extended hand guards while still providing sophisticated nonlinear gas flow control through the internal regulator portion.

Inventive Principle:
Principle #7Nested doll (Nesting)

Function Achieved in This Case

Enables flexible and precise control of gas flow, preventing discharge gas from being directed back towards the operator, enhancing firearm reliability and safety by accommodating various ammunition types and accessories while minimizing gas reflection.

Implementation Method 1

The regulator portion includes an opening that is placed in fluid communication with the aperture when the regulator portion is inserted into the gas plug bore. By rotating the gas plug, the operator can align the opening with the aperture to various degrees, thereby controlling the area of fluid communication and regulating gas flow in a nonlinear manner.

AI summary

A firearm gas piston system provides tool-less removal and adjustment of gas flow along a nonlinear gradient and directs exhaust discharge away from the operator. The system includes a gas block with gas channels for directing exhaust gas away from an operator and a gas plug bore configured to accommodate insertion of a gas plug. The gas plug can include an actuator for rotating the gas plug, a key that fits within a key notch and key channel inside the gas plug bore to secure the gas plug within the bore, and a regulator portion to control the flow of discharge gas from a firearm barrel. The regulator portion includes a passage with two opening segments that accept discharge gas from the barrel and direct the gas through another opening disposed in a regulator cutout and to a piston portion of the gas block.
