Customizable Firearm System with Quick-Change Barrel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bullpup style firearms have limited options for barrel configurations, which restricts users' ability to choose barrel length, caliber, twist rates, muzzle threading, and other characteristics, limiting customization and performance.
Innovation Solution
A customizable firearm system that integrates existing AR components, allowing for the use of various barrel types in a compact bullpup configuration, featuring a quick-change barrel assembly and a removable bolt carrier assembly for toolless barrel swaps and total caliber changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a longer barrel is used to enhance distance capabilities, then the overall length of the firearm increases, but mobility and maneuverability deteriorate
Solution Approach 1:
The firearm is divided into separable modules including the barrel assembly, bolt carrier assembly, and receiver. The barrel can be quickly detached and replaced, allowing users to switch between longer barrels for distance capabilities and shorter barrels for mobility, resolving the contradiction between these two requirements.
Solution Approach 2:
The system transitions from a fixed configuration to a dynamic, reconfigurable system. The quick-change barrel assembly and removable bolt carrier assembly enable the firearm to adapt its configuration based on operational needs, allowing optimization between distance and mobility as required.
2Adaptability or versatility
If multiple barrel configurations are offered to enhance customization, then device complexity increases, but ease of manufacture deteriorates
Solution Approach 1:
The receiver and mounting mechanisms are designed to be universal, accommodating multiple barrel configurations and calibers through standardized interfaces. This allows the core firearm platform to remain simple to manufacture while supporting extensive customization through interchangeable components.
Solution Approach 2:
Instead of manufacturing different firearm platforms for various configurations, the system changes parameters by swapping barrels with different lengths, calibers, and specifications. The standardized mounting system maintains manufacturing simplicity while enabling extensive parameter variation through the interchangeable barrel options.
3Device complexity
If traditional fixed barrel assemblies are used, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The barrel assembly is segmented into a modular quick-change design that separates the barrel from the receiver through standardized interfaces. This segmentation enables easy interchangeability of barrels while maintaining a relatively simple overall structure through the use of standardized mounting mechanisms.
