Modular Rifle Chassis with Interchangeable Adapters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rifle designs lack easy interchangeability and high-strength connections for forestocks and butt stocks, limiting adaptability and ergonomic configurations.
Innovation Solution
A modular rifle assembly with a central chassis and adapters that removably secure forestocks and butt stocks, utilizing a combination of slots, flanges, and fasteners to provide strong and adjustable connections, allowing for easy interchangeability and various ergonomic configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional rifle designs use fixed forestocks and butt stocks, then structural strength is maintained, but adaptability and ease of interchangeability are reduced
Solution Approach 1:
The rifle is divided into separate modular components: a central chassis, interchangeable forestocks, and interchangeable butt stocks. Each component can be independently selected and attached to create different rifle configurations, enabling adaptability while maintaining structural integrity through standardized connection interfaces.
Solution Approach 2:
The central chassis is designed with universal adapter interfaces that can accommodate multiple types of forestocks and butt stocks. The adapters serve multiple functions: providing strong mechanical attachment, enabling easy interchangeability, and maintaining structural strength across different component combinations.
2Ease of operation
If removable adapters are used to secure forestocks and butt stocks, then ease of interchangeability is improved, but connection strength may be compromised
Solution Approach 1:
Adapters serve as intermediary components between the central chassis and the forestock/butt stock. These adapters are specifically designed to provide both easy removal/installation capabilities and high-strength connections through features like slots, flanges, and multiple fastening points that distribute mechanical loads across the connection interface.

AI summary
A rifle assembly includes a central chassis for carrying an action including a trigger and a trigger guard, the central chassis having a front portion and a rear portion, a rifle fore-end for carrying a barrel, the fore-end having a rear portion, and a fore-end adapter having a rear portion removably secured to the central chassis front portion and a front portion removably secured to the fore-end rear portion. The rifle assembly further includes a rifle butt stock having a front portion and a butt stock adapter having a rear portion removably secured to the butt stock front portion and a front portion removably secured to the central chassis front portion.
