Adjustable Firearm Stock Rail Mount Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm stocks are not typically detachable or mountable to accessory rails, leading to discomfort and reduced accuracy and safety for users of varying sizes.
Innovation Solution
An adjustable firearm stock with a base that mounts on a firearm's rail, featuring an extension element and locking actuator, allowing for customizable orientation and secure attachment to the firearm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the firearm stock is built into the firearm as a fixed component, then the structural strength and stability are improved, but the adaptability to different user sizes is worsened
Solution Approach 1:
The stock is divided into a fixed base portion integrated with the firearm and a detachable extension element that can be adjusted or removed. This segmentation allows the main structural component to remain fixed for strength while the extension portion adapts to different users through adjustment mechanisms or interchangeable parts.
Solution Approach 2:
The stock transitions from a completely fixed structure to a dynamic system where the extension element can be adjusted in length or configuration. This allows the stock to adapt to different user sizes while maintaining a secure connection to the firearm through the base portion.
2Adaptability or versatility
If the firearm stock is made detachable and mountable to accessory rails, then the adaptability to different users is improved, but the structural strength and stability are worsened
Solution Approach 1:
The stock system is segmented into a heavily constructed base portion that maintains structural integrity and a separate extension element that provides adaptability. The base remains fixed to the firearm while the extension can be adjusted or detached, separating the strength function from the adaptability function.
Solution Approach 2:
The base portion is designed with universal mounting capabilities (such as rail interfaces) that allow the stock to be attached to different firearm configurations while maintaining its structural role. This universal mounting system enables adaptability without compromising the base's strength.
3Ease of operation
If the stock is made adjustable for different user sizes, then the ease of operation and comfort are improved, but the device complexity is worsened
Solution Approach 1:
The adjustable stock is segmented into a simple fixed base and a separate extension element containing the adjustment mechanism. This concentrates the complexity in one detachable component rather than the entire stock, making the adjustment system easier to manufacture and maintain while preserving handling comfort.

AI summary
A firearm includes: a rail secured to the firearm; and an adjustable firearm stock secured to the rail, the adjustable firearm stock including: a base removably secured to the rail of the firearm and defining an extension element bore; and an extension element positioned in the extension element bore, the extension element configured to move along an axis of the extension element bore. A method of using a firearm includes: mounting a base of an adjustable firearm stock to a rail of the firearm; and sliding an extension element of the adjustable firearm stock through an extension element bore of the base to adjust the adjustable firearm stock to a desired orientation.
