Pistol Slide Locking Mechanism Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pistol designs require coordinated force and fluency to disassemble the slide, which can be challenging for inexperienced users due to the need to manage the forces of multiple springs simultaneously.
Innovation Solution
A locking slide mechanism comprising two small plates arranged in a slot, where the spring plate can be easily pulled out and pivoted away from the barrel path, allowing the slide to be disassembled without coordinated force application, featuring a 'U'-shaped spring plate and an 'A'-shaped retaining plate for secure locking and easy release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single locking slide is used to secure the barrel and slide, then the locking mechanism is simple and reliable, but disassembly requires coordinated force application against multiple springs which is difficult for inexperienced users
Solution Approach 1:
The single locking slide is divided into two separate plates: a retaining plate (4) and a spring plate (6). This segmentation allows the spring plate to be independently manipulated and removed from the slot, enabling disassembly without requiring coordinated force application against multiple springs simultaneously. The retaining plate maintains the locking function while the spring plate's independent removal simplifies the disassembly process.
2Strength
If the locking slide is positioned to securely lock the barrel, then the locking strength is high, but the slide cannot be easily released without applying force against spring pressure
Solution Approach 1:
The spring plate (6) is designed to be extractable from the slot independently from the retaining plate (4). By taking out the spring plate first, the spring pressure is removed from the locking mechanism, allowing the barrel and slide to be released without requiring users to apply force against active spring pressure. The retaining plate maintains the locking strength when the spring plate is in place.
3Device complexity
If a one-piece locking slide is used, then the structure is simple, but it requires coordinated two-handed operation to disassemble which reduces ease of use
Solution Approach 1:
The locking slide is segmented into two functionally distinct plates that can be manipulated separately. The spring plate (6) can be independently removed from the slot by pulling it laterally, eliminating the need for coordinated two-handed operation. This segmentation increases structural complexity slightly but dramatically improves ease of operation, especially for inexperienced users.
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 easy and safe disassembly of the pistol slide by inexperienced users, as the design allows the slide to be pulled forward without requiring simultaneous force application against multiple springs, enhancing usability and safety.
Implementation Method 1
a lower plate, a spring plate 6, onto which the coil spring 7 presses upwards from below

AI summary
The invention relates to a pistol with a grip (1) and a slide (16) having a barrel (8) and movable thereon along guides (18). The grip incorporates a locking device for the forward movement of the barrel (8), which includes a retaining plate (4) for a barrel projection (5) that is movable in a slot (2) and acted upon by a spring (7). To facilitate operation, a spring plate (6) is provided in the slot (2) between the spring (7) and the retaining plate (4). This spring plate is designed to be partially retractable from the slot (2) transversely to the central plane of the pistol. In this extended position, it can be pivoted, together with the retaining plate (4), against the force of the spring (7). This allows the retaining plate (4) to move out of the path of movement of the barrel projection (5), and the slide can then be pulled forward.
