Solution Overview

Problem

Loading a gun magazine is a repetitive and tiring task that causes sore thumbs and wrists, especially when filling to capacity, with pistol magazines being particularly difficult.

Innovation Solution

A magazine loader apparatus with a magazine holder, loading arm, plunger, and bullet loader that simplifies the loading process by allowing a bullet to be temporarily held and easily inserted into the magazine, featuring a bullet ram, feed platform, and angled bullet loader for efficient loading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If manual loading of magazine is performed, then the magazine can be filled to capacity, but the user experiences sore thumbs and wrists due to repetitive and tiring action

Engineering Contradiction:
Improvemagazine capacityVSAvoiduser fatigue
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent introduces a loading device as an intermediary tool between the user and the magazine. This device includes a loading chamber that receives bullets, a loading arm that moves the bullets, and a plunger that pushes bullets into the magazine. The device acts as a mediator that performs the repetitive pushing action, eliminating the need for the user to manually press each bullet into the magazine, thus preventing sore thumbs and wrist fatigue while still filling the magazine to capacity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The loading device is designed to perform the loading operation automatically once bullets are placed in the loading chamber. The loading arm mechanism and plunger work together to automatically push bullets from the loading chamber into the magazine without requiring continuous manual intervention for each bullet. This self-service mechanism reduces the repetitive manual action that causes user fatigue.

Inventive Principle:
Principle #25Self-service

2Quantity of substance

If pistol magazine is loaded to capacity, then the magazine is fully loaded, but the loading process becomes particularly difficult and tiring

Engineering Contradiction:
Improvemagazine capacityVSAvoidloading difficulty
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The loading device serves as an intermediary that handles the complexity of loading pistol magazines to capacity. The device includes a loading chamber sized to receive multiple bullets, a loading arm positioned to engage the bullets, and a plunger that applies force to push bullets into the magazine. This intermediary mechanism manages the complexity of filling pistol magazines completely, making the process easier despite the high capacity requirement.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The device allows bullets to be preliminarily placed in the loading chamber before the actual loading into the magazine occurs. The loading chamber serves as a preliminary holding area where bullets are positioned and prepared. The loading arm and plunger then perform the actual transfer action, separating the preparation phase from the forceful insertion phase, thereby reducing loading difficulty.

Inventive Principle:
Principle #10Preliminary action

AI summary

A magazine loader apparatus and method includes in one embodiment, a magazine holder where the magazine holder is configured to removably hold a magazine and where the magazine holder includes a loading chamber configured to receive a bullet. A loading arm connected with the magazine holder, a plunger connected with the loading arm, and a bullet loader where the bullet loader is configured to temporarily hold the bullet and where the bullet loader is removably connectable with the magazine holder at the loading chamber such that the bullet exits the bullet loader into the loading chamber.
