Self-Locking Magazine Mechanism for Firearm Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ammunition magazines for firearms, particularly those in compliance with California's regulations, require manual locking mechanisms that can be cumbersome and lack a tool-free, self-actuating locking mechanism to prevent removal without disassembling the firearm action.
Innovation Solution
A self-locking mechanism using a spring-loaded locking wheel that automatically engages and disengages upon downward movement of the magazine, ensuring secure attachment without tools, and can be unlocked only by inserting a tool into a specific bore.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual locking mechanism is used to secure the magazine to the firearm, then the magazine can be securely attached, but the locking process becomes cumbersome and requires additional user actions
Solution Approach 1:
The locking mechanism is self-actuating through downward movement of the magazine body relative to the receiver, automatically engaging the locking member without requiring manual intervention or additional user actions to secure the magazine to the firearm
Solution Approach 2:
The locking member is pre-positioned within the receiver such that downward movement of the magazine body automatically triggers engagement, performing the locking action in advance of any potential removal attempt
2Adaptability or versatility
If a fixed magazine is required to comply with regulations, then regulatory compliance is achieved, but the magazine cannot be removed without disassembling the firearm action
Solution Approach 1:
The locking mechanism transitions from a static fixed state to a dynamic system where the locking member can be actuated by downward movement, allowing the magazine to be securely attached during use and easily removed by applying downward force, thus providing both regulatory compliance and operational flexibility
3Ease of operation
If a tool-free locking mechanism is implemented, then ease of operation is improved, but the complexity of the mechanism increases
Solution Approach 1:
The locking function is extracted from a separate manual operation and integrated into the natural downward movement of the magazine body, using the existing motion required for magazine insertion to automatically engage the locking member, thereby simplifying the overall system
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 mechanism provides a secure, tool-free locking solution that complies with regulatory requirements by automatically locking the magazine in place within the firearm, preventing removal without disassembly, thus enhancing user safety and regulatory compliance.
Implementation Method 1
the locking mechanism includes a spring biasing the locking member towards the first position
Data Source
AI summary
An ammunition magazine includes a self-locking mechanism configured to prevent the magazine from being removed from a firearm without disassembly of the firearm action.
