Firearm Magazine Spring Base Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm magazines have limited storage capacity due to space occupied by the spring and insert piece, are difficult to assemble and disassemble, and have many parts prone to malfunction.
Innovation Solution
A firearm magazine design with a housing, a spring having a downward bent section that fits inside the base, reducing space usage and allowing for more cartridges, and a loader for easy stacking and positioning, along with a slideable base secured by the bent section, minimizing parts and simplifying assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the spring and insert piece are mounted inside the housing as in prior art magazines, then the magazine can function properly, but the storage capacity for cartridges is reduced due to space occupation by these components
Solution Approach 1:
The patent combines the spring mounting function directly into the base structure. The spring is mounted inside the base rather than requiring a separate insert piece, merging two components into one integrated structure. This eliminates the space required for the insert piece while maintaining spring functionality.
Solution Approach 2:
The patent utilizes the vertical dimension by having the spring extend downward into the base structure. Instead of occupying horizontal space within the housing cavity, the spring is positioned in the vertical dimension within the base, effectively moving the component from the housing volume to the base volume, thereby increasing cartridge storage space.
2Reliability
If the magazine is designed with multiple parts including separate base piece, insert piece, and pin mounting system, then the functionality is achieved, but the assembly and disassembly process becomes difficult
Solution Approach 1:
The patent merges the base piece and insert piece into a single integrated base structure. The spring mounting features are directly formed in the base, eliminating the need for a separate insert piece. This reduction in part count directly simplifies the assembly and disassembly process while maintaining all necessary functions.
Solution Approach 2:
The patent removes the pin mounting system and separate insert piece from the design. The base is designed to be directly removable from the housing without requiring pins or additional fastening mechanisms, extracting unnecessary components that complicated the assembly process.
3Stability of the object's composition
If the magazine includes multiple separate parts such as base piece, insert piece, and pin, then the structural requirements are met, but the number of parts increases leading to higher possibility of malfunction
Solution Approach 1:
The patent combines multiple separate parts into fewer integrated components. The base piece and insert piece are merged into a single base structure, and the pin mounting system is eliminated. This consolidation reduces the total number of parts from three separate components (base piece, insert piece, pin) to a single integrated base, thereby reducing the probability of malfunction while maintaining structural stability.
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
Increases storage capacity by utilizing space efficiently, reduces the number of parts to minimize malfunctions, and facilitates easy assembly and disassembly, providing a tactical advantage by accommodating additional cartridges within the same height.
Implementation Method 1
A spring is mounted inside the housing and adapted to receive a cartridge. The spring is biased against the cartridge
Implementation Method 2
The spring is of a generally spiral shape terminating with a downward bent section

AI summary
A magazine for improved stacking capacity includes a housing, a front wall connected to a back wall by sidewalls, a base, a spring adapted to be received inside a recess in the base in order to reduce the space occupied by the spring. The spring having various spiral sections wherein the spiral section having different lengths so that the spiral sections fit into each other when the spring is compressed against cartridges in order to enable stacking of additional cartridges.
