Cartridge Package with Longitudinal Slots for Rapid Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cartridge packages require manual insertion of cartridges into magazines, leading to finger fatigue and difficulty in loading larger caliber cartridges due to spring force, especially in harsh conditions.
Innovation Solution
A cartridge package with an elongated housing divided into sub-compartments and longitudinal slots, allowing for efficient loading of cartridges into a magazine using a second magazine as a pusher, reducing manual effort and accommodating a higher number of cartridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fingers are used to push cartridges from the cartridge package into the cartridge magazine, then the loading operation can be performed, but finger fatigue occurs quickly and it becomes impossible to push cartridges in harsh weather conditions or with larger caliber cartridges
Solution Approach 1:
A second cartridge magazine is used as an intermediary tool to push cartridges from the cartridge package into the first cartridge magazine. This mediator transfers the loading function from human fingers to the magazine mechanism, eliminating finger fatigue and enabling reliable loading of large caliber cartridges that would be impossible to push manually.
2Productivity
If cartridges are loaded one by one by hand into the cartridge magazine, then precise control of each cartridge is achieved, but the loading time becomes excessively long
Solution Approach 1:
Multiple cartridges are loaded simultaneously by using the second cartridge magazine as a pusher to transfer multiple cartridges at once from the cartridge package into the first cartridge magazine. This combines multiple individual loading operations into a single action, dramatically increasing productivity and reducing the time required for the loading operation.
3Reliability
If a large spring force is used in the cartridge magazine to ensure proper cartridge seating, then reliable cartridge retention is achieved, but it becomes impossible for an ordinary person to press the cartridges into the magazine
Solution Approach 1:
The second cartridge magazine serves as a mediator that applies the necessary force to overcome the strong spring resistance in the first cartridge magazine. This intermediary tool enables ordinary persons to load large caliber cartridges that would otherwise be impossible to press in due to the great spring force, while still ensuring reliable cartridge retention through proper spring tension.

AI summary
The cartridge package (100) comprises an elongated housing (110) with a first 5 compartment (120) being divided into two sub-compartments (121, 122) with a flexible intermediate wall (117). Each sub-compartment receives a row (R1, R2) of cartridges (150). Opposite side walls (111, 112) of the housing are provided with a longitudinal slot (160, 162). A mouth portion (130) extending outwards from a top end (E2) of the housing comprises a second compartment 10 (135) having an open top end (E3) and being adapted to receive a mouth portion of a first cartridge magazine in order to load the cartridges from the cartridge package into the first cartridge magazine. The width of each longitudinal slot is dimensioned to receive an edge of a second cartridge magazine in order to push a respective row of cartridges from the cartridge package into the first cartridge magazine.
