Solution Overview

Problem

Bolt-action firearms are limited to firing a single caliber and shape of ammunition due to their fixed magazine well, requiring multiple firearms for different ammunition types.

Innovation Solution

An interchangeable magazine well system that allows a single firearm to accommodate various ammunition shapes and calibers by using a magazine well housing with flanges and geometric interfaces, enabling quick exchange of different magazine wells and magazines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a fixed magazine well is used in bolt-action firearms, then the structural simplicity and manufacturing ease are improved, but the adaptability to different ammunition types deteriorates

Engineering Contradiction:
Improvestructural simplicityVSAvoidadaptability to different ammunition types
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The magazine well is divided into a permanent portion (integrated with the receiver) and an interchangeable portion (magazine well insert). The interchangeable portion can be removed and replaced with different inserts designed for various ammunition types, allowing the firearm to adapt to different calibers and magazine configurations while keeping the overall structure simple and easy to manufacture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The receiver is designed with a universal interface that can accommodate multiple types of magazine well inserts. This universal design allows a single receiver to support various ammunition types through interchangeable inserts, making the firearm multi-functional without requiring multiple complete firearm designs.

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

2Adaptability or versatility

If multiple firearms are used to fire different ammunition types, then the adaptability to different ammunition types is improved, but the device complexity and cost increase

Engineering Contradiction:
Improveability to fire different ammunition typesVSAvoidnumber of firearms required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single firearm receiver is designed to universally accept multiple magazine well inserts for different ammunition types. This eliminates the need for multiple separate firearms, reducing device complexity while maintaining the ability to fire various ammunition types through the interchangeable insert system.

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

Solution Approach 2:

The functionality of multiple firearms is merged into a single receiver by integrating multiple magazine well insert options. Instead of requiring separate firearms for different ammunition types, the receiver combines these functions through a unified interface that accepts various interchangeable inserts.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If an interchangeable magazine well system is implemented, then the adaptability to different ammunition types is improved, but the device complexity increases

Engineering Contradiction:
Improvecaliber and magazine type interchangeabilityVSAvoidmagazine well structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The magazine well is segmented into permanent structural components (receiver integration, mounting features) and interchangeable components (inserts for different calibers). This segmentation allows the complex adaptability features to be confined to removable inserts, keeping the main receiver structure relatively simple while achieving high versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The interchangeable complexity is localized to specific magazine well inserts rather than the entire firearm. Each insert is designed with specific geometric interfaces and internal features tailored to particular ammunition types, concentrating the complexity where it is needed while keeping the rest of the firearm simple.

Inventive Principle:
Principle #3Local quality

AI summary

A single bolt-action receiver with a lower having the ability to accept multiple shaped magazines through an interchangeable magazine well, defining a magazine chamber shape. The interchangeable magazine wells may further comprise a first flange and a first aperture and a second flange and a second aperture. The first interchangeable magazine well defining a first magazine chamber shape, may be configured to receive a first ammunition magazine containing a first shape and first caliber ammunition. The first interchangeable magazine well can be removed and a second interchangeable magazine well containing a second chamber shape, may be configured to receive a second ammunition magazine shape containing a second shape and second caliber ammunition.
