Solution Overview

Problem

Existing magazine loading devices are limited to loading cartridges with a single case head diameter, requiring multiple devices for different calibers, which is inefficient for users with rifles utilizing various case head diameters.

Innovation Solution

A magazine loading device featuring a movable rimlock mechanism with springs and a modular design that accommodates multiple calibers, including a pusher device with ergonomic handles and adaptable magazine adapters for one-handed operation, allowing for the rapid loading of multiple calibers and styles without the need for multiple devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a magazine loader is designed to work with cartridges of a single case head diameter, then the loading mechanism can be simple and reliable, but the user must own multiple devices for different calibers

Engineering Contradiction:
Improvecaliber compatibilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The magazine loader incorporates a universal rimlock mechanism that can accommodate multiple case head diameters through adjustable components. The device includes a set of interchangeable or adjustable rimlocks that can be configured to match different cartridge sizes, allowing a single device to serve multiple calibers including 5.56×45 mm, 7.62×51 mm, and 7.62×39 mm

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The loader features movable and adjustable components including a dynamic rimlock system that can adapt its positioning to accommodate different case head diameters. The slideway and channel components can be adjusted or reconfigured to match the specific requirements of different cartridge calibers

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a pusher device uses a pulling motion operated by forearm and wrist muscles, then the device can be compact, but it requires use of minor arm muscles and is less ergonomic

Engineering Contradiction:
Improveergonomic operationVSAvoidhandle mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Instead of requiring the user to pull the pusher device through a channel, the invention inverts the mechanism to allow the user to push cartridges along the slideway using a pushing motion. This inversion enables engagement of the major arm muscles (biceps and triceps) rather than the minor muscles of the forearm and wrist, significantly improving ergonomics

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If multiple magazine adapters are provided for different specifications, then versatility is improved, but the device complexity increases

Engineering Contradiction:
Improvemagazine type compatibilityVSAvoidadapter system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The magazine loader is divided into modular components including separate magazine adapters that can be independently selected and attached. Each adapter is designed for specific magazine types and capacities, allowing users to segment the overall system into manageable, interchangeable components based on their specific needs

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

AI summary

A device for loading a plurality of ammunition rounds or cartridges, containing a rim, groove, or flange, of non-determined size or into a firearm magazine of a non-determined capacity by means of a magazine adapter, in one or more hand strokes. The main chassis, or cartridge retainer, may be asymmetric in design allowing for ambidextrous operation and accessory expansion.
