Ammunition Magazine Pull Mechanism for Deformation-Free Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual loading of ammunition cartridges into gun magazines is time-consuming and painful, and conventional devices often result in magazine deformation and issues with cartridge feeding, with existing solutions either having complex components prone to contamination or a pull element that dangles outside the magazine.
Innovation Solution
An ammunition magazine design featuring a spring and follower system with a pull mechanism that allows the follower to be compressed and then released, enabling easy loading without pressing cartridges against the spring bias, and a releasable lock that prevents the pull element from protruding, ensuring it remains within the magazine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual loading is used, then the magazine structure remains simple, but the loading process is time-consuming and painful
Solution Approach 1:
The magazine system performs the compression action automatically through the spring mechanism. When the pull element is released, the spring self-compresses to push the follower and cartridges upward, eliminating the need for manual pressing by the user.
Solution Approach 2:
The system transitions from a static manual pressing operation to a dynamic automated process. The spring provides continuous dynamic force to compress and push cartridges, replacing the static manual effort with a dynamic mechanical system.
2Ease of operation
If a pull element is used to compress the spring, then loading becomes easier, but the pull element dangles outside the magazine causing contamination risk
Solution Approach 1:
The pull element is nested within the magazine structure during operation. It extends through the follower for compression, then is retrieved and stored inside the magazine body, similar to a nested doll configuration where one element is contained within another.
Solution Approach 2:
The problematic dangling portion of the pull element is extracted and removed from the external environment. The pull element is completely contained within the magazine housing, eliminating exposure to external contaminants while maintaining its functional capability.
3Device complexity
If conventional manual loading is used, then no additional components are needed, but the magazine lips deform over time affecting cartridge feeding
Solution Approach 1:
The spring mechanism performs the compression and pushing action automatically, serving the loading function without requiring repeated manual intervention. This self-service action prevents the cumulative deformation that occurs with repeated manual pressing on the magazine lips.
Solution Approach 2:
The spring acts as an intermediary between the user's single compression action and the multiple cartridge loading operations. It mediates the force application, distributing the loading action smoothly without concentrating stress on the magazine lips, thereby preventing deformation.
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
Facilitates efficient and comfortable loading of ammunition without deforming the magazine and eliminates the risk of contamination or component failure, as the pull element is securely housed within the magazine, enhancing cartridge feeding reliability.
Implementation Method 1
a spring and follower system with a pull mechanism that allows the follower to be compressed and then released
Implementation Method 2
The spring, being in contact with the base plate, biases the follower towards the open end

AI summary
Ammunition magazine comprises a follower having a pull receiving passage adapted to cooperate with a pull, the passage is defined by at least one passage wall that extends from an underside surface of the follower to a head engaging surface, a pull extends through the follower at the pull receiving passage through a port in the floor plate and has a head at a head end connected to a semirigid elongated body to a tail at a tail end, the body is adapted and sized to slide within the pull receiving passage of the follower, the head is larger than the pull receiving passage and adapted to engage with head engaging surface of the follower when the pull is pulled towards the floor plate to compress the follower spring and disengage from the head engaging surface of the follower when the pull is pushed into the loaded magazine.
