Firearm Adapter for Barrel Exchange

Solution Overview

Problem

The high cost and impracticality of owning multiple firearms for different activities, such as target shooting and hunting, due to the need for firearms of varying calibers and sizes.

Innovation Solution

A modification kit comprising an adapter with external and internal threaded surfaces, a securing element, and a barrel with a coupling portion and flange, allowing for the detachable coupling of different barrels to a bolt action rifle, enabling the rifle to be reconfigured for various activities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple firearms of different calibers and sizes are owned for different activities, then suitability for various activities is improved, but cost and device complexity increase

Engineering Contradiction:

Improvesuitability for various activitiesVSAvoidnumber of firearms

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The receiver is designed with a universal adapter interface that can accommodate multiple types of barrels through standardized coupling mechanisms. The adapter includes external threaded surfaces that interface with the receiver's internal threaded surfaces, allowing the same receiver to be used with barrels of different calibers and lengths for various activities including target shooting and hunting.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The firearm system is divided into separable components: the receiver, the adapter, and the barrel. The adapter acts as an intermediate component that can be detached and reattached to different barrels. This segmentation allows users to exchange barrels based on activity requirements while retaining the same receiver, reducing the need to own multiple complete firearms.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple firearms are owned for different activities, then activity-specific suitability is improved, but cost increases

Engineering Contradiction:

Improveactivity-specific suitabilityVSAvoidtotal cost

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The receiver is designed with a universal adapter interface that can accommodate multiple types of barrels through standardized coupling mechanisms. The adapter includes external threaded surfaces that interface with the receiver's internal threaded surfaces, allowing the same receiver to be used with barrels of different calibers and lengths for various activities including target shooting and hunting.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If barrels of different calibers and lengths are exchanged, then adaptability for different activities is improved, but ease of operation decreases

Engineering Contradiction:

Improvebarrel exchange capabilityVSAvoidbarrel installation complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The firearm system is divided into separable components: the receiver, the adapter, and the barrel. The adapter acts as an intermediate component that can be detached and reattached to different barrels. This segmentation allows users to exchange barrels based on activity requirements while retaining the same receiver, reducing the need to own multiple complete firearms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The adapter serves as an intermediary component between the receiver and the barrel. It includes external threaded surfaces for coupling to the receiver's internal threaded surfaces and internal features for securing the barrel. This intermediary design simplifies the exchange process by providing a standardized interface that reduces installation complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A kit for modifying a firearm includes an adapter, and the adapter includes an external threaded surface configured to detachably couple to an internal threaded surface of a receiver of the firearm. An adapter bore is disposed opposite the external threaded surface, and the adapter bore is configured to receive a barrel of the firearm. The kit further includes a securing element, and the securing element includes a securing element bore configured to receive the barrel. The securing element is configured to detachably couple to the adapter and thereby secure the barrel to the adapter.
