Integrated Magazine Extension Spring Guide for Hunting Rifles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magazine extensions for semi-automatic and pump-action hunting rifles increase capacity but reduce spring compression, leading to feeding problems and complexity in assembly, with independent components prone to loss.
Innovation Solution
A magazine extension system featuring a tubular body with an integrated extension spring and spring guide, secured by a cover pin, which maintains spring compression and guides the magazine spring, ensuring consistent operation and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a cylindrical hollow extension tube is attached to the end of the magazine tube to increase magazine capacity, then the magazine capacity increases, but the spring compression decreases leading to reduced propulsion force and feeding problems
Solution Approach 1:
The patent combines the extension tube, extension spring, and spring guide into a single integrated magazine extension assembly. This merging ensures that when the extension is attached to the magazine tube, the extension spring is pre-positioned and pre-compressed within the extension tube, maintaining proper spring force for feeding ammunition into the chamber even as capacity increases
2Reliability
If an extension spring and spring guide are used with a magazine extension to maintain spring compression, then feeding problems are eliminated, but the system complexity increases and components are prone to loss
Solution Approach 1:
The extension spring and spring guide are integrated into the extension tube assembly during manufacturing, creating a single unified component. This eliminates the need for separate assembly steps and reduces the number of independent parts that could be lost, while maintaining the reliability benefits of having both the spring and guide in place
Solution Approach 2:
The spring guide is positioned inside the extension tube, and the extension spring is nested within the extension tube alongside the spring guide. This nested arrangement consolidates multiple components into a compact integrated unit that functions as a single assembly, reducing complexity while maintaining functional integrity
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
The system effectively increases magazine capacity without compromising spring force, preventing feeding issues and simplifying assembly and transport by integrating the spring and guide within a secure, modular design.
Implementation Method 1
At least one extension spring which one end may be connected to the extension spring guide and the other end may be connected to the extension body cover
