Fixed Stock with Integral Storage and Cam Plug
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm butt stocks lack ease of installation and integration with firearms, and often do not provide accessible storage for accessories, which are essential for civilian use and personal preference.
Innovation Solution
A fixed butt stock design featuring a slip-on geometry that interfaces with a firearm's receiver extension tube using a cam plug for secure attachment, incorporating a storage compartment with a door for easy access, enhancing stability and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed butt stock is designed with simple slip-on geometry, then ease of installation is improved, but storage functionality is worsened
Solution Approach 1:
The patent combines the butt stock structure with an integrated storage compartment into a single unified component. The storage compartment is built into the butt stock body itself, merging two separate functions (support and storage) into one device, thereby achieving both easy installation and storage functionality simultaneously
2Quantity of substance
If a storage compartment is added to the butt stock, then storage capacity is improved, but device complexity is worsened
Solution Approach 1:
The butt stock is segmented into distinct functional zones: the main stock body for support, the cam plug mechanism for attachment, and the storage compartment with door for storage. This segmentation allows each component to be optimized independently while maintaining overall simplicity of the entire assembly
3Reliability
If a cam plug attachment mechanism is used, then reliability of attachment is improved, but ease of operation is worsened
Solution Approach 1:
The cam plug is pre-positioned within the butt stock body during manufacturing, with its cam surface already oriented correctly. This preliminary action eliminates the need for complex alignment procedures during installation, allowing the user to simply insert and rotate the plug to achieve secure attachment

AI summary
The present invention is a fixed stock with integral storage that utilizes a cam plug inside the storage compartment to secure the stock to a firearm. In the preferred embodiment, the cam plug interfaces with the hind edge of the stock body and is therefore visible outside the stock, for a stronger and more secure hold.
