Magnetic Ejection Magazine Door Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic magazine devices for firearms do not effectively utilize a magnet to remotely actuate an ejection mechanism for automatically ejecting the ammunition magazine when the last round is fed into the firearm.
Innovation Solution
An automatic magazine device that includes a hollow ammunition magazine with a follower attached to a magnet. The magnet urges a hingedly attached door into a disengaged position, allowing the ammunition magazine to drop out of the firearm when the last round is fed in.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active mechanical communication is used between the follower and ejection device, then reliable ejection can be achieved, but the device complexity and potential for mechanical failure increase
Solution Approach 1:
The patent replaces the traditional mechanical communication system between the follower and ejection device with a magnetic field-based actuation system. A magnet in the follower remotely actuates a magnetically responsive element in the door mechanism, eliminating the need for direct mechanical linkages and reducing mechanical failure points while maintaining reliable ejection functionality
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the follower and the door mechanism. The magnet in the follower creates a magnetic field that acts on the magnetically responsive element in the door, serving as a non-contact intermediary that transfers force without mechanical contact, thereby reducing complexity while maintaining reliability
2Force
If direct mechanical linkages are used for ejection, then force transmission is reliable, but the device complexity increases
Solution Approach 1:
The patent substitutes direct mechanical linkages with a magnetic field-based force transmission system. The magnet in the follower generates a magnetic field that directly actuates the magnetically responsive element in the door, transmitting force without mechanical contact and eliminating complex linkages while maintaining effective force transmission for door actuation
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 device ensures automatic ejection of the ammunition magazine without mechanical failure, reducing the need for active mechanical communication between the follower and the ejection device.
Implementation Method 1
a magnet is attached to the follower... The magnet urges the door into a disengaged position

AI summary
An automatically ejecting magazine device includes an ammunition magazine which is substantially hollow for receiving ammunition for a firearm. A follower is movably disposed within the ammunition magazine to support ammunition for the firearm and a magnet is attached to the follower. A door is hingedly attached to the ammunition magazine and the door has a recess which is engaged by a magazine release of the firearm to retain the ammunition magazine in the firearm. The magnet urges the door into a disengaged position such that the recess is not accessible to the magazine release. In this way the ammunition magazine can drop out of the firearm when the last round of ammunition is fed into the firearm.
