Firearm Magazine Locking Mechanism with Rotor Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved magazine safety mechanisms for firearms that prevent unintentional and unauthorized firing, addressing issues such as accidental discharges due to poor training, mechanical unsoundness, and misuse by unauthorized users, while avoiding reductions in ammunition capacity, complexity, and weight.
Innovation Solution
A magazine with a locking mechanism that allows users to select between locked and unlocked conditions, featuring a rotor and elongated shaft with a block element to prevent firearm operation and extraction when locked, and enabling operation when unlocked, along with a status indicator for tactile confirmation of the locking state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magazine-based safety mechanism is implemented to prevent accidental discharge, then firearm safety is improved, but the ammunition capacity of the magazine is reduced
Solution Approach 1:
The blocking element is nested within the magazine body structure, utilizing the existing magazine space efficiently. The blocking element can be stored within the magazine housing when not in use, and only protrudes when needed to block the trigger bar, thus not reducing the overall ammunition capacity of the magazine.
Solution Approach 2:
The blocking element is extracted from the traditional firearm safety mechanisms and integrated into the magazine itself. This allows the safety function to be performed by the magazine without requiring separate safety devices that would occupy additional space or reduce ammunition capacity.
2Reliability
If a magazine-based safety mechanism is implemented to prevent accidental discharge, then firearm safety is improved, but the device complexity increases
Solution Approach 1:
The safety function is merged with the existing magazine structure and trigger bar mechanism. The blocking element works in conjunction with the trigger bar rather than requiring a completely separate safety system, thereby reducing overall device complexity while maintaining safety functionality.
Solution Approach 2:
The blocking element is designed to be manually operable by the user through simple manipulation. The mechanism serves itself by using the user's own hand movements to engage or disengage the blocking element, eliminating the need for complex automated safety systems.
3Reliability
If a magazine-based safety mechanism is implemented to prevent accidental discharge, then firearm safety is improved, but the weight of the magazine increases
Solution Approach 1:
The blocking element is designed as a simple, lightweight component that can be easily manufactured from low-density materials. Rather than using heavy metal safety mechanisms, the blocking element can be made from lightweight polymers or thin-walled metals, minimizing weight addition.
Solution Approach 2:
The blocking element only requires sufficient mass at the specific location where it contacts the trigger bar to effectively block movement. The rest of the magazine structure can remain lightweight, concentrating the necessary weight only where functionally required for the safety blocking action.
4Reliability
If a magazine-based safety mechanism is implemented to prevent accidental discharge, then firearm safety is improved, but the ease of operation deteriorates
Solution Approach 1:
The blocking element is positioned and dimensioned to be easily manipulated by the user's finger or thumb. The user can engage or disengage the blocking element through natural hand movements without requiring complex procedures, maintaining ease of operation while ensuring safety when needed.
Solution Approach 2:
The blocking element is pre-positioned within the magazine structure so that it is already in place to block the trigger bar when engaged. This preliminary positioning eliminates the need for complex adjustment or alignment procedures during operation, allowing the user to simply activate or deactivate the safety function with a simple motion.

AI summary
A magazine is provided for a firearm. The magazine comprises a locking mechanism. The locking mechanism has a user interface adapted to enable a user to select between a locked condition and an unlocked condition. The locking mechanism has a rotor movable between a first rotational position when the locking mechanism is in the locked condition and a second rotational position when the locking mechanism is in the unlocked condition. The magazine comprises an elongated shaft connected to the rotor. The magazine comprises a block element connected to the elongated shaft. The block element is adapted to move between a first position when the locking mechanism is in the locked condition in which at least one of firearm operation and magazine extraction are prevented, and a second position when the locking mechanism is in the unlocked condition in which firearm operation and magazine extraction are enabled.
