Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lightweight automatic firearms experience reduced accuracy due to repeated recoil forces, necessitating a design that maintains accuracy without the weight penalties of heavier systems.
Innovation Solution
A recoil-operated automatic weapon with a linkless ammunition feed system and a cylindrical telescoped or case-less ammunition system, featuring a barrel and bolt assembly that moves linearly relative to the barrel's bore axis, and a chamber that linearly moves to seal against the barrel, allowing for precise firing and efficient ammunition feeding without links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If lightweight automatic firearms are used, then weight is reduced and portability is improved, but accuracy deteriorates due to repeated recoil forces
Solution Approach 1:
The patent implements a dynamic recoil management system where the barrel and chamber assembly moves rearward on recoil cushions during firing, then returns forward using a spring mechanism. This dynamic operation absorbs and distributes recoil forces over time, reducing their impact on accuracy while maintaining lightweight construction. The movable barrel-chamber assembly on guided rails allows controlled motion that mitigates recoil effects.
Solution Approach 2:
The patent introduces recoil cushions as intermediary elements between the barrel-chamber assembly and the weapon stock. These cushions act as mediators that absorb and dampen recoil forces, preventing direct transmission of shock to the shooter and reducing accuracy degradation. The spring mechanism serves as another intermediary that stores and releases energy to manage recoil dynamics.
2Reliability
If traditional linked ammunition systems are used, then reliability is improved, but device complexity increases and link-related misfires occur
Solution Approach 1:
The patent extracts and eliminates the link component from the ammunition system, transitioning from linked cartridges to caseless or cased telescoped ammunition without connecting links. This removal of the link element simplifies the feed system, reduces potential failure points, and eliminates link-related misfires while maintaining reliable ammunition delivery through direct magazine-to-chamber feeding.
Solution Approach 2:
The ammunition feeding system operates on a self-service basis where the cylindrical magazine automatically presents rounds to the chamber through coordinated movement of the barrel-chamber assembly and magazine components. The system uses the recoil-driven cyclic motion to automatically cycle ammunition from the magazine into the chamber without requiring complex feed mechanisms or link assemblies.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances accuracy and reliability by minimizing recoil impacts and eliminating link-related misfires, while the linkless feed system ensures consistent ammunition presentation, improving operational efficiency and user training.
Implementation Method 1
a recoil spring contained within the stock and adapted to be compressed by and push the barrel extension forward
Implementation Method 2
A shock tube is contained within the buffer body and comprises a series of orifices in its circumferential side that allow the hydraulic fluid to pass from the shock tube to the buffer body and vice versa
Implementation Method 3
The piston rod is pushed forward by the recoil spring. As the piston moves forward, there are fewer and fewer orifices for the piston to push hydraulic fluid through, this results in a gradual reduction of flow area
Implementation Method 4
The toggle rollers are guided by the toggle rail, causing the rear toggles to rotate about an axis, which then causes the front toggles to rotate about an axis. This motion straightens the toggles, pushing the chamber forward

AI summary
A recoil-operated, impulse averaging, air-cooled, magazine-fed, automatic weapon. An operating group of the weapon includes a chamber, a bolt, a barrel extension and one or more toggles. The recoil action of the weapon from firing a first round drives the toggles in a motion constrained by a cam way. The toggles then drive the chamber in a linear reciprocating motion ejecting a first round and over-riding the next round. An impulse averaging system controls the speed of the recoil.
