Solution Overview

Problem

The lack of industry standardization in magazine catches limits the interchangeability of different magazines with a single firearm model, as existing latching mechanisms are incompatible with various magazine types due to differing retention feature locations and styles.

Innovation Solution

A modular and interchangeable magazine well insert system that uses a universal actuation member to operate multiple magazine retention systems, including side and front latching mechanisms, allowing for the use of magazines with different catch styles and calibers, with interchangeable magazine well inserts configured to mate with a common mounting interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single latching mechanism is designed for a specific magazine type, then the latching mechanism can reliably retain that specific magazine type, but the firearm cannot accommodate different magazine types with varying catch styles and positions

Engineering Contradiction:
Improvemagazine interchangeabilityVSAvoidlatching mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The magazine well is divided into multiple interchangeable insert components, each configured for a specific magazine catch style. This segmentation allows the user to swap inserts rather than redesigning the entire latching mechanism, thereby achieving magazine interchangeability while keeping individual insert designs relatively simple.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The magazine well system is designed to accept multiple types of magazine inserts, each serving a specific function for different magazine catch styles. The universal magazine well structure can accommodate front catch, side catch, and other variations through interchangeable inserts, making the system multi-functional and adaptable to various magazine types.

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

2Adaptability or versatility

If the latching mechanism is designed to accommodate multiple magazine types, then magazine interchangeability is improved, but the complexity of the latching mechanism increases

Engineering Contradiction:
Improvemagazine interchangeabilityVSAvoidlatching operation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

By segmenting the latching function into separate interchangeable inserts, each insert maintains a simple, dedicated latching design for its specific magazine type. This prevents the need for a single complex mechanism that would be difficult to operate, while still achieving multi-magazine compatibility through insertion swapping.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The interchangeable insert acts as an intermediary between the magazine and the firearm's action. Each insert is designed with specific latching features that match particular magazine catch styles, simplifying the interaction between the magazine and firearm while enabling compatibility with multiple magazine types through the mediator insert.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If different latching mechanisms are provided for different magazine types, then compatibility with various catch styles is achieved, but the device complexity and number of parts increases

Engineering Contradiction:
Improvecatch style compatibilityVSAvoidnumber of latching components
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The latching system is segmented into modular inserts that can be independently designed and manufactured for specific catch styles. This segmentation allows for specialized optimization of each insert for its intended magazine type while keeping the overall system manageable through standardized mounting interfaces and a limited number of insert variants.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The magazine well is designed as a universal mounting structure that can accommodate multiple types of latching inserts. This universal interface reduces the need for entirely separate latching mechanisms for different magazine types, as the same mounting location can accept different inserts depending on the desired magazine compatibility.

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

AI summary

A modular magazine well insert system accepts and latches different types of magazines including front and side catch styles. The system includes a plurality of magazine well inserts each having a common mounting interface which interfaces with a mounting feature formed in a receptacle of the firearm stock. The inserts may have a common basic configuration with some different features adapted for use with different magazine catch features, such as latching levers for front catch magazines or lateral apertures to access side catch magazines. A universal latch stud slideably mounted in the stock comprises features which cooperate with each of the magazine well inserts to retain and release both catch styles of magazines in the insert.
