Pivot-Mounted Rifle Magazine Insert for Collision-Free Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rifle magazines face challenges in feeding cartridges into the chamber without collisions and require complex handling for reloading, especially when the breech is actuated.
Innovation Solution
An interchangeable magazine with a pivot-mounted magazine insert that can move between upward and downward positions, facilitated by a compression spring, allowing the top cartridge to be oriented obliquely for easier insertion and featuring a trigger unit for secure handling and quick reloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the magazine insert is fixed in position, then the structure is simple, but cartridge feeding becomes difficult and may cause collisions with the breech
Solution Approach 1:
The magazine insert is made movable rather than fixed, allowing it to pivot about a transverse axis between different positions. This dynamic capability enables the insert to move to an upper position during breech actuation to avoid collisions, while still providing stable cartridge feeding in the lower position.
Solution Approach 2:
The magazine system is divided into separate components: the carrier with housing and the magazine insert with cartridges. This segmentation allows the insert to be independently positioned and moved relative to the carrier, facilitating the pivoting motion needed for collision-free operation.
2Ease of operation
If the magazine insert is mounted to pivot about a transverse axis, then cartridge feeding is simplified, but the magazine insert requires additional mounting components
Solution Approach 1:
The magazine insert pivots about a transverse axis to dynamically adjust its position. During breech actuation, the insert moves to an upper position clear of the breech path, eliminating collisions. During normal operation, it remains in a lower position for proper cartridge alignment and feeding.
Solution Approach 2:
The pivot bearing is pre-positioned on the carrier, and the magazine insert is designed with the pivot connection already integrated. This preliminary arrangement ensures that the pivoting capability is built-in and ready for operation without requiring additional complex mounting procedures.
3Productivity
If the magazine and trigger unit are separate, then reloading is simpler, but handling and safety require more steps
Solution Approach 1:
The magazine insert with cartridges and the trigger unit are combined into a single integrated assembly. This merging allows both components to be removed and reinstalled together as one unit, simplifying the reloading process while maintaining safe handling procedures through the unified design.
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
Simplifies cartridge feeding and enhances reloading efficiency, ensuring safe and quick reassembly and disassembly of the magazine and trigger assembly, improving handling and safety of the rifle.
Implementation Method 1
The magazine insert is pressed into the upwardly pivoted cartridge feed position by a compression spring designed, for example, as a leaf spring
