Rifle Breech Mechanism Segmentation for Simplified Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breech mechanisms for firearms are difficult to dismantle and assemble, requiring complex procedures and multiple parts, which complicates maintenance and disassembly.
Innovation Solution
A breech mechanism with a control element that includes an unlocking ramp and a pin-shaped control element, allowing for easy insertion and removal, and a disassembly safety device to prevent unintended disassembly, along with a breech actuation device that can be slidably guided between guide surfaces, facilitating the breech's movement into locking and unlocking positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional breech mechanism with multiple locking blocks and complex actuation components is used, then the locking reliability is improved, but the device complexity and difficulty of disassembly increase
Solution Approach 1:
The breech mechanism is divided into separable components: a closure body that can be detached from the barrel assembly, and a control element that can be independently removed. This segmentation allows the locking mechanism to maintain reliability through precise mating surfaces and locking features, while simultaneously enabling easy disassembly by simply separating the segmented components without complex procedures
Solution Approach 2:
The control element is extracted as a separate, removable component from the closure body. This control element contains the essential locking and unlocking functionality, allowing it to be taken out for maintenance or replacement without disassembling the entire breech mechanism. The extraction principle simplifies the overall structure by isolating the control function into a standalone unit that can be easily manipulated
2Stability of the object's composition
If a complex multi-component breech mechanism is used, then the locking stability is improved, but the ease of operation for disassembly and assembly deteriorates
Solution Approach 1:
The closure body is segmented into modular components that maintain stable locking through precision-engineered interfaces. The segmentation allows each component to be independently manufactured and assembled, ensuring stable locking while enabling straightforward disassembly by separating the modular segments along defined interfaces
Solution Approach 2:
The control element is designed with preliminary positioning features and guide surfaces that automatically align components during assembly. This preliminary action ensures stable locking is achieved automatically when components are brought together, eliminating the need for complex alignment procedures or multiple adjustment steps during disassembly and assembly operations

AI summary
The invention relates to a bolt for a rifle comprising a bolt actuation device (5) that is longitudinally displaceable along the rifle and a bolt body (6) that is movable between a locked position and an unlocked position by the bolt actuation device (5). The bolt actuation device (5) is connected to the bolt body (6) via a control element (31) that is movable transversely to the bolt body (6) and designed as a connector, and which interacts with the bolt body (6) to displace it between an upper locked position and a lower unlocked position.
