Integrated Magazine Coupling System with Rotational Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ammunition magazine coupling methods are cumbersome, unreliable, require additional components or tools, and are limited in functionality, making them difficult to assemble and disassemble, especially for users with gloves or large fingers.
Innovation Solution
A bi-directional, self-aligning magazine coupling system integrated into the housing, featuring a rotational ¼ turn locking mechanism and preload ramps, allowing quick engagement and disengagement without tools, along with a debris cover and grip-enhancing design for easy handling and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external clamp style coupling devices are used, then magazines can be coupled together, but the coupling system becomes bulky and requires additional external components
Solution Approach 1:
The coupling system is integrated directly into the magazine housing structure, merging the coupling function with the magazine body rather than using separate external components. The housing includes integrated coupling elements such as protrusions and recesses that engage with each other to secure multiple magazines together, eliminating the need for external clamp-style devices.
Solution Approach 2:
The magazine housing serves multiple functions: it contains the ammunition follower and spring mechanism, provides structural support, and incorporates the coupling system for attaching multiple magazines together. This multi-functional design eliminates the need for separate dedicated coupling devices.
2Reliability
If taping magazines together is used, then magazines can be coupled, but the method is difficult to assemble and disassemble
Solution Approach 1:
The coupling system is divided into separate engageable components on adjacent magazines, with protrusions on one magazine fitting into recesses on another. This segmentation allows for quick engagement and disengagement by simply separating the magnetic components without requiring tools or complex manipulation.
Solution Approach 2:
The coupling system incorporates magnetic elements that provide automatic attraction and alignment when magazines are brought together, enabling dynamic self-alignment during assembly. The magnetic force maintains continuous engagement while allowing easy separation when force is applied, providing both reliability and ease of operation.
3Reliability
If external coupling devices are used, then magazines can be coupled, but tools such as screwdrivers are required
Solution Approach 1:
The coupling system uses magnetic elements that automatically attract and secure the magazines together without requiring manual tool operation. The magnetic force self-aligns the coupling components and maintains engagement, eliminating the need for screwdrivers or other tools to assemble or disassemble the coupling.
Solution Approach 2:
The traditional mechanical screw or clamp-based coupling system is replaced with a magnetic coupling mechanism. The magnetic field provides the securing force that previously required mechanical fasteners, allowing for tool-free operation while maintaining reliable attachment.
4Reliability
If external clamp style coupling devices are used, then magazines can be coupled, but the coupling system is limited to two magazines
Solution Approach 1:
The integrated housing design incorporates coupling elements on multiple sides of the magazine body, allowing the same magazine structure to couple with multiple other magazines simultaneously. The universal coupling interface enables flexibility in configuring magazine arrays of various sizes and arrangements.
Solution Approach 2:
The coupling system extends beyond a single coupling point to include multiple engagement points distributed across the magazine housing. This multi-dimensional arrangement of coupling elements allows magazines to be coupled in various configurations and orientations, enabling attachment of more than two magazines.
5Ease of repair
If traditional floor plate designs are used, then magazines can be disassembled, but users with gloves or large fingers have difficulty removing the floor plate
Solution Approach 1:
The floor plate incorporates a localized release mechanism with a protrusion that can be easily accessed and actuated by a gloved finger or thumb. This localized feature provides a specific grip point that is ergonomically designed for gloved hand operation, making floor plate removal easy even when wearing protective gear.

AI summary
Aspects of a magazine for use with a repeating firearm are described. One unique aspect is that the magazine is fabricated completely from a translucent polymer that is highly resistant to mechanical, chemical, and thermal failures commonly affecting magazines. Another aspect of the magazine is the inclusion of a coupling system fully integrated into the housing that allows magazines to be securely joined together without the use of tools or additional components. A further aspect of the magazine is the easy release button design allowing the magazine to be disassembled by large or gloved fingers without need for a tool to depress the release button.
