Solution Overview

Problem

Loading cartridges into firearm magazines can be difficult, especially when the magazine is nearly full, due to the spring force required, which may be challenging for individuals with weaker hands or arthritis.

Innovation Solution

A clamping assembly and loader assembly that includes a main frame, side plates, and pivotable connection plates, allowing for the secure clamping and loading of cartridges into a firearm magazine with enhanced leverage and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If cartridges are loaded one at a time against spring force, then the magazine can be filled to capacity, but the loading difficulty increases significantly when the magazine is nearly full

Engineering Contradiction:

Improvenumber of cartridges loadedVSAvoidloading difficulty

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

A loading tool with a clamping assembly acts as an intermediary device between the user and the magazine. The clamping assembly secures the magazine during loading, while the plunger member provides mechanical advantage to overcome spring force. This intermediary tool distributes the loading effort across multiple components rather than requiring direct manual force against the spring.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The clamping assembly incorporates pivotable connection plates that allow dynamic adjustment and movement during the loading process. The plunger member is movably coupled to the cartridge member, enabling it to move dynamically as cartridges are loaded. This dynamic design allows the system to adapt to the increasing spring force as the magazine fills.

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If manual loading is performed without assistance, then no additional equipment is needed, but individuals with weaker hands or arthritis cannot load the magazine

Engineering Contradiction:

Improvesimplicity of loading mechanismVSAvoiduser capability requirement

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The loading tool serves as a mechanical intermediary that amplifies user input force. The plunger member's movable coupling to the cartridge member creates a lever arm that provides mechanical advantage, allowing users with limited hand strength to generate sufficient force to compress the spring and load cartridges.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The loading tool is divided into distinct functional components: the clamping assembly (with main frame, side plates, and connection plates) that secures the magazine, and the plunger member that applies loading force. This segmentation allows each component to be optimized for its specific function while working together to reduce the physical effort required.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If a clamping assembly with pivotable connection plates is used, then loading ease is improved, but the device complexity increases

Engineering Contradiction:

Improveloading easeVSAvoidclamping assembly structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The pivotable connection plates provide dynamic movement capability that adapts to the loading process. As the plunger compresses the spring and loads cartridges, the connection plates can pivot to accommodate the changing geometry and forces, maintaining effective clamping throughout the loading sequence without requiring complex adjustment mechanisms.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The clamping assembly merges multiple functions into a single integrated structure: the main frame provides overall support, the side plates clamp the magazine, and the pivotable connection plates simultaneously serve as both structural connectors and movement joints. This merging reduces the need for separate components while maintaining the required functionality.

Inventive Principle:

Principle #5Merging (Combining)
