Ammunition Retainer Tabs Prevent Siphon Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ammunition boxes experience jamming and siphon effects due to the non-symmetric design of linked ammunition, causing movement and interlocking of bullets when tilted or subjected to vibration, leading to loss of fire.
Innovation Solution
An ammunition retainer apparatus with elongated body and spaced tabs is placed on top of divider walls, locking the linked ammunition belt in place, preventing movement between chambers and eliminating siphon effects while allowing free withdrawal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If linked ammunition is stored in ammunition boxes with divider walls creating multiple chambers, then the ammunition can be organized and stored efficiently, but the non-symmetric design of bullets causes them to move between chambers when tilted or vibrated, leading to interlocking and jamming
Solution Approach 1:
A retainer member is introduced as an intermediary component between the divider wall and the linked ammunition. This retainer member extends across the top surface of the divider wall and physically blocks the ammunition from moving between chambers, mediating the interaction between the storage structure and the ammunition to prevent harmful movement while maintaining organized storage
2Adaptability or versatility
If the ammunition box is tilted during transport or use, then gravity causes linked ammunition to fall towards the lowest point, moving from one chamber to another, but this movement causes the pointed projectile end to entangle between bullets or fall on top of other ammunition, creating interlocking and jamming
Solution Approach 1:
The retainer member is positioned in advance on top of the divider walls to create a preliminary barrier against gravitational movement. When the box is tilted, the retainer members already in place prevent the ammunition from moving towards the lowest point, countering the gravitational force before it can cause entanglement or jamming
3Productivity
If one chamber is emptied during firing and the ammunition level drops below the neighboring chamber's level, then the siphon effect causes linked ammunition to move from one chamber to the next, but this movement causes interlocking and ammunition jamming
Solution Approach 1:
The retainer member acts as a mediator that blocks the siphon effect by preventing the ammunition from moving between chambers based on level differences. It maintains consistent ammunition flow from each chamber to the feeding mechanism without allowing uncontrolled movement between chambers that would cause interlocking
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 solution effectively prevents jamming and siphon effects by securing the linked ammunition, ensuring it remains in its original chamber until pulled out, maintaining consistent ammunition flow and preventing interlocking.
Implementation Method 1
Another problem is the siphon effect that will occur when one chamber is emptied during firing and the level of linked ammunition gets below the neighboring chamber's level. When this occurs the linked ammunition will start to move from one chamber to the next due to the siphon effect
Implementation Method 2
During pitch the linked ammunition has a tendency to fall towards the lowest point in the ammunition box due to gravity, thereby falling from one chamber to another

AI summary
An ammunition retainer apparatus for restraining a continuous belt of linked ammunition cartridges loaded into bays of an ammunition box or magazine from flowing over a divider wall from a first bay to a second bay adjacent to the first bay. The ammunition retainer apparatus comprises an elongated body having on a first side, a first pair of tabs rigidly attached to the body and protruding from the body in a first direction, and on a second side, a second pair of tabs rigidly attached to the body and protruding from the body in a second direction.
