Solution Overview

Problem

Existing magazine coupling devices do not provide a means to securely and easily connect multiple standard firearm magazines without structural modifications, nor do they allow for quick and secure access to additional magazines.

Innovation Solution

A coupling device featuring floor plate structures with shared bases, button release holes, and release channels that allow multiple magazines to form a locked unit with separation capability, utilizing existing magazine components for secure attachment and quick release, without modifying the individual magazines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If existing magazine coupling devices are used to connect multiple magazines together, then the firearm's magazine capacity is increased, but the individual magazines require structural modifications and the connection is not secure or easily accessible

Engineering Contradiction:
Improvemagazine capacityVSAvoidstructural modifications required
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The coupling device serves as an intermediary component that connects multiple magazines together without requiring modifications to the magazines themselves. The device includes a body with channels that receive and secure the floor plates of individual magazines, allowing them to function as a unified multi-magazine unit while preserving the integrity of each individual magazine.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If magazines are connected securely to form a locked unit, then the connection reliability is improved, but the ability to quickly access and separate individual magazines is reduced

Engineering Contradiction:
Improveconnection securityVSAvoidquick access capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The coupling device incorporates dynamic elements including movable floor plates that can be independently removed from each magazine, and release buttons that allow for quick disconnection. The floor plates are retained by retention members that can be easily actuated, enabling the user to quickly access or separate individual magazines from the connected unit while maintaining secure connection during use.

Inventive Principle:
Principle #15Dynamics

3Reliability

If multiple magazines are connected as a single unit, then the risk of lost or damaged magazines is reduced, but the complexity of the coupling device increases

Engineering Contradiction:
Improvemagazine retentionVSAvoidcoupling device structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The coupling device is segmented into modular components including a body with individual channels for each magazine, movable floor plates for each magazine position, and independent retention members. This segmentation allows the device to securely hold multiple magazines while maintaining simplicity through standardized repeating units that can be manufactured and assembled efficiently.

Inventive Principle:
Principle #1Segmentation

AI summary

A magazine coupling device includes two or more floor plate structures sharing a common base for connecting a plurality of magazines together to form a single connected unit. Each floor plate structure replaces a magazine floor plate secured to a bottom end of a detachable magazine. A release button receptacle extends through the base. A release button access channel extends from the release button receptacle to an outer surface of the base forming an access opening to allow access to the release button receptacle from outside the coupling device.
