Solution Overview

Problem

Current firearm gas-operated reloading systems require manual tuning for each specific round, which can be time-consuming and prone to jamming due to improper gas adjustment, leading to inefficiencies in ejecting and loading rounds.

Innovation Solution

A delayed-opposed-piston gas action system that includes a bolt, bolt carrier, gas block, bolt piston, and vent piston, where expelled gas is vented to eject the casing and load a new round, utilizing springs and pistons to automate the process, reducing the need for manual adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual gas adjustment is used to tune the firearm for each specific round, then the gas can be optimized for ejection and loading, but the process becomes time-consuming and complex

Engineering Contradiction:
Improvereliability of ejection and loadingVSAvoidtime required for manual tuning
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system automatically adjusts gas port positioning based on detected round characteristics without requiring manual intervention. The gas adjustment mechanism is self-regulating, using the round's own properties (diameter, pressure) to determine the optimal gas port configuration, thereby eliminating time-consuming manual tuning while maintaining reliable ejection and loading

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates sensors that detect round characteristics and provide feedback to the gas adjustment mechanism. This closed-loop control allows the system to automatically optimize gas port positioning based on real-time measurements of the inserted round, ensuring reliable operation without manual intervention

Inventive Principle:
Principle #23Feedback

2Reliability

If manual gas adjustment is used, then gas can be optimized for each round, but the process is prone to user error and jamming

Engineering Contradiction:
Improvereliability of ejection and loadingVSAvoidease of gas adjustment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The gas adjustment mechanism automatically positions the gas port based on detected round characteristics without requiring user intervention. This eliminates user error in gas adjustment while maintaining optimal gas flow for reliable ejection and loading across different round types

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system replaces manual mechanical adjustment with an automated mechanism that uses sensors and actuators to position the gas port. This substitution of manual operation with an automated control system eliminates user error while maintaining ease of use, as the system handles adjustment automatically

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If fixed gas port size is used, then the system is simpler, but it cannot adapt to different rounds and causes jamming

Engineering Contradiction:
Improveadaptability to different roundsVSAvoidcomplexity of gas adjustment system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The gas port positioning is made dynamic rather than fixed. The system automatically adjusts the gas port position based on detected round characteristics, allowing the same physical mechanism to serve multiple round types. This dynamic adaptation maintains versatility while keeping the underlying mechanism relatively simple through automated control

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The gas adjustment mechanism is designed to handle multiple round types universally. A single adjustable gas port system can accommodate different calibers and round characteristics by automatically positioning itself, eliminating the need for multiple fixed gas ports or manual intervention, thus achieving versatility without proportional increases in complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

System for a delayed-opposed-piston gas action assembly. Specifically, the system is comprised of a bolt, a bolt carrier, a gas block, a bolt piston, and a vent piston. Each piston will have a corresponding piston cup that will act on the piston from the gas discharged from the round. Each piston will also have a corresponding spring to bring the piston back to its original position after the gas has dissipated from the system. During the process of the firearm being discharged, the two pistons will act on the bolt carrier, causing the casing of the round to be ejected from the firearm, and a new round to be loaded into the firearm, so that the firearm can be discharged again.
