Bolt Action Slide Conversion Device Locking Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms with standard slides automatically open the chamber upon firing, which can affect accuracy and speed, and there is a need for a solution that allows for bolt-action operation while complying with regulations and user preferences.
Innovation Solution
A bolt-action conversion device that uses a locking plate and clamp assembly to prevent the slide from opening upon firing, allowing manual operation to expose the chamber for loading, compatible with various firearm types and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard slide is used in a firearm, then the chamber automatically opens upon firing, but this reduces accuracy and speed
Solution Approach 1:
The slide is segmented into two functional parts: the main slide body that remains stationary during firing, and a separate chamber-exposing mechanism that is manually actuated. This segmentation allows the slide to maintain structural integrity and seal the chamber during firing while still enabling chamber exposure when needed through manual operation of the charging handle.
Solution Approach 2:
A charging handle serves as an intermediary mechanism between the user and the chamber-exposing function. The charging handle is coupled to the slide and, when manually actuated, exposes the chamber without requiring automatic movement of the slide itself. This intermediary allows precise control over chamber exposure while maintaining chamber seal during firing.
2Reliability
If manual bolt-action operation is implemented, then accuracy and control are enhanced, but device complexity increases
Solution Approach 1:
The conversion device is designed to be universally compatible with multiple firearm platforms including pistols and rifles. The same basic mechanism (locking plate, charging handle, and coupling components) can be adapted to different firearm types, reducing the need for platform-specific complex mechanisms while achieving bolt-action functionality across various platforms.
Solution Approach 2:
Instead of modifying the entire firearm to implement bolt-action operation, the invention inverts the approach by adding a minimal conversion device to an existing semi-automatic slide. The conversion device includes a locking plate that prevents automatic slide movement and a charging handle that manually exposes the chamber, transforming the firearm's operation mode with minimal added complexity.
3Reliability
If the slide is prevented from opening upon firing, then chamber sealing is improved, but the mechanism becomes more complex
Solution Approach 1:
The automatic chamber-opening function is extracted from the firing process by removing the linkage between cartridge ignition and slide movement. The locking plate prevents the slide from being propelled backward by gas pressure, and the charging handle becomes the sole mechanism for chamber exposure, decoupling the firing function from the chamber-exposing function.
Solution Approach 2:
The locking plate incorporates dynamic elements including a spring-loaded follower that automatically engages and disengages the locking plate's locking surface during manual operation. This dynamic mechanism allows the locking plate to maintain a simple structure while providing reliable chamber sealing during firing and smooth manual operation during charging.

AI summary
A bolt-action conversion device includes a slide clamp having a longitudinal cavity, a first pin hole, and a receiver in a direction orthogonal to the longitudinal cavity and substantially adjacent to a forward end of the slide clamp. The device also includes a locking plate having a second pin hole. A body portion of the locking plate has a narrow dimension and a broad dimension relative to the narrow dimension. When the locking plate is inserted into the receiver of the slide clamp with the first pin hole and the second pin hole aligned, an opening is formed between an upper surface of the locking plate and an internal surface of the longitudinal internal cavity. The longitudinal cavity accepts a slide of a firearm such that the opening is aligned with the barrel and at least a portion of the locking plate is aligned with a frame.
