Gas-Operated Rifle Barrel Segmentation for Simplified Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas-operated rifles face difficulties in simplified assembly and disassembly of the barrel due to complex retention mechanisms, making disassembly cumbersome and time-consuming.
Innovation Solution
The design features a barrel with a rear part that can be firmly connected to the lock housing and a front part that cantilevers freely, allowing for easy lifting and disconnection without additional front-end disassembly, along with a gas extraction block receptacle for simplified assembly and integration of the pressure piston within the gas extraction block for easy dismantling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the barrel is firmly connected to the lock housing with additional retaining elements, then the barrel is securely fixed, but the disassembly process becomes complex and time-consuming
Solution Approach 1:
The barrel is divided into two distinct parts: a rear part that can be firmly connected to the lock housing, and a front part that cantilevers freely without additional connections. This segmentation allows the rear part to maintain secure fixation while the front part enables simple disassembly by lifting, resolving the contradiction between secure mounting and ease of disassembly.
2Reliability
If the barrel requires additional retaining elements for fixation, then the barrel is securely mounted, but the number of parts and assembly complexity increases
Solution Approach 1:
By segmenting the barrel into rear and front parts with different connection characteristics, the design reduces the number of retaining elements needed. The rear part uses minimal fixation points while the front part requires no additional connections, simplifying the overall assembly structure while maintaining secure mounting.
Solution Approach 2:
Instead of making the entire barrel firmly connected with multiple retaining elements, the invention inverts the approach by making only the necessary rear part firmly connected while allowing the front part to cantilever freely. This inversion reduces complexity while maintaining the required security for proper function.
3Ease of manufacture
If the barrel is made as a single integrated piece, then manufacturing is simplified, but disassembly requires more steps to access retention mechanisms
Solution Approach 1:
The barrel is segmented into rear and front parts that can be manufactured separately and then assembled. This segmentation allows each part to be optimized for its specific function while enabling simple disassembly. The rear part with fixation features can be manufactured and tested independently, as can the front part, before final assembly, improving both manufacturability and serviceability.
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
This design significantly simplifies the assembly and disassembly process, allowing for quick and easy barrel removal and installation without the need to dismantle the fore-end, enhancing the overall ease of use and maintenance of the semi-automatic rifle.
Implementation Method 1
a gas extraction block 24 which projects downwards with a gas cylinder 25 and a gas extraction bore 26 opening into the barrel 2, in which a pressure piston 27 is guided in an axially displaceable manner
Implementation Method 2
The pressure piston 27 contains a piston rod 28 which projects through a rear bore in the gas extraction block 24 and which cooperates with the carrier 10 of the closure actuating device 5 to move the closure body 6 into the unlocked position

AI summary
The invention relates to a gas-operated rifle with a lock housing (1), a guide rod (4) projecting forward from the lock housing (1) in the direction of firing, a breech actuation device (5) slidably arranged on the guide rod (4) which cooperates with a breech body (6) to move it between a locked position and an unlocked position, and a barrel (2) attached to the lock housing (1) with a gas extraction block (24) which includes at least one gas extraction bore (26) opening into the barrel (2) and a pressure piston (27) slidably guided in the gas extraction block (24) for moving the breech actuation device (5) against the force of a breech spring (7).Simplified assembly and disassembly of the barrel can be achieved by the barrel (2) comprising a rear part (17) that can be placed on the lock housing (1) and firmly connected to it, and a front part (18) that cantilevers freely from the lock housing (1) without a fixed connection to the guide rod (4).
