Fixed Ammunition Feeding Device With Spring Latch

Solution Overview

Problem

Existing ammunition feeding devices for firearms are often removable, requiring users to carry multiple magazines to support ammunition needs, which can be inconvenient and increase the risk of mismanagement.

Innovation Solution

A fixed ammunition feeding device with a spring latch that automatically deploys and secures the magazine in place once fully seated, preventing removal without disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a removable magazine system is used, then ease of operation is improved, but reliability deteriorates due to risk of accidental removal

Engineering Contradiction:

Improveease of magazine changeVSAvoidrisk of accidental removal

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The magazine system is divided into two distinct states: removable magazines for ease of change and fixed magazines for reliability. The invention transitions from a single removable magazine design to a system that can operate in both removable and fixed configurations, allowing users to select the appropriate mode based on operational requirements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The magazine retention mechanism is made dynamic, allowing it to transition between removable and fixed states. The spring latch mechanism can be engaged to secure the magazine firmly in place during operation, while still allowing intentional removal when needed, providing adaptability between the two opposing requirements.

Inventive Principle:

Principle #15Dynamics

2Reliability

If a fixed magazine system is used, then reliability is improved, but ease of operation deteriorates due to difficulty in removal

Engineering Contradiction:

Improvesecurity of magazine attachmentVSAvoiddifficulty of magazine removal

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The magazine retention mechanism is made dynamic, allowing it to transition between removable and fixed states. The spring latch mechanism can be engaged to secure the magazine firmly in place during operation, while still allowing intentional removal when needed, providing adaptability between the two opposing requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The spring latch mechanism is designed to automatically engage and secure the magazine when inserted, providing self-securing functionality that eliminates the need for manual latching operations while maintaining the ability to remove the magazine through the magazine release mechanism.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If multiple magazines are carried, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveammunition supply flexibilityVSAvoidnumber of magazines to manage

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The magazine system is divided into two distinct states: removable magazines for ease of change and fixed magazines for reliability. The invention transitions from a single removable magazine design to a system that can operate in both removable and fixed configurations, allowing users to select the appropriate mode based on operational requirements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system allows changing the retention parameter of the magazine from removable to fixed through engagement of the spring latch mechanism. This parameter change enables a single magazine to provide the functionality of multiple magazine configurations, reducing the need to carry and manage multiple separate magazines.

Inventive Principle:

Principle #35Parameter changes
