Fixed Barrel Pistol Disassembly Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Training pistols with fixed barrels deviate significantly from real weapons during disassembly due to differences in mass and energy, making it difficult to replicate the disassembly process of real weapons with rotary or break-open barrels, which is essential for realistic training.
Innovation Solution
A training pistol design with a fixed barrel and non-positive ground closure, where the barrel is arranged in a locking block within the grip, and an unlocking ramp on the breech allows for intuitive disassembly without mechanical release devices, mimicking the disassembly process of real weapons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed barrel with blowback action is used in training pistols, then the design is simplified and mass is reduced, but the disassembly process deviates significantly from real weapons
Solution Approach 1:
The patent applies the copying principle by replicating the disassembly sequence of real rotary-barrel weapons in the training pistol. The breech block is copied to rotate and disconnect from the barrel, and the barrel is copied to be extractable from the grip, mirroring the operational steps of real weapons despite using a fixed barrel blowback mechanism.
Solution Approach 2:
The patent applies segmentation by dividing the pistol into distinct separable components: the grip containing the trigger mechanism, the barrel mounted in the grip, and the breech block that can rotate and disconnect. This segmentation enables the multi-step disassembly process that mimics real weapons, contrasting with the integrated design of conventional fixed-barrel pistols.
2Ease of operation
If the barrel is made extractable and the breech block is made rotatable, then disassembly similarity to real weapons is improved, but the structural integrity and rigidity are compromised
Solution Approach 1:
The patent applies dynamics by making the connection between components conditional rather than fixed. The barrel can be firmly mounted in the grip during operation but becomes extractable when the breech block is rotated to the disconnected position. The breech block itself rotates between locked and disconnected states, providing dynamic adaptability that maintains rigidity when needed while enabling disassembly when required.
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
Enables a compact and component-efficient design that closely resembles real weapons' disassembly procedures, enhancing training realism without compromising functionality.
Implementation Method 1
an unlocking ramp on the breech allows for intuitive disassembly without mechanical release devices
Implementation Method 2
The barrel is arranged in a locking block, which ensures the connection to the grip, and is thus fixed to the housing

AI summary
The invention relates to a fixed-barrel pistol, in particular a training weapon, comprising a grip (2), slide (4) and barrel (3), a slide stop device, a firing pin mechanism (10) and preferably a disassembly lever (7) which can be moved into a disassembly position in which it releases the forward movement of the slide (4). This release is only possible when no magazine is in the chamber and the slide (4) is locked in place.The invention is characterized in that the barrel (3) is fastened in the grip (2) by a locking means (14), that the locking means (14) can be brought into a release position in which it releases the barrel (3), that a release gap (18) is provided between the barrel (3) and the breech (4), upon overcoming this gap after the disassembly lever (7) has been moved into the disassembly position, a release ramp (13) provided on the breech (4) forces the locking means (14) into the release position.
