Modular Gun Barrel System with Universal Mounting Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic rifles, such as AR-15 and Ruger 10/22, have limited universality of parts and components due to differences in bullet caliber, length, gunpowder quantity, and firing range, restricting the use of interchangeable barrels and bullets across different models.
Innovation Solution
A gun device with a modular design allowing the replacement of barrels of different sizes, featuring a gun body with a threading and positioning slot, a guide adapter with a projecting part and groove, and a barrel key, enabling the integration of AR-15 and Ruger 10/22 barrels, facilitating the use of 0.22 inch caliber bullets in AR-15 rifles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional automatic rifles use fixed barrel designs specific to their caliber (AR-15 using 5.56mm bullets, Ruger 10/22 using 0.22 inch caliber bullets), then each rifle achieves optimal performance for its designated bullet type, but the universality of parts and components is limited, requiring users to choose bullets according to their equipment
Solution Approach 1:
The barrel is designed as a separable component that can be removed and replaced. The barrel includes a barrel body and a barrel cap that can be detached, allowing users to switch between different barrel types (AR-15 caliber and Ruger 10/22 caliber) based on shooting needs, thereby achieving bullet compatibility without redesigning the entire rifle
Solution Approach 2:
The gun body is designed with universal mounting features (threading and positioning slots) that can accommodate different barrel types. The standardized interface allows a single gun body to work with multiple barrel configurations, enabling one rifle to function with both 5.56mm AR-15 bullets and 0.22 inch caliber Ruger 10/22 bullets
2Length of moving object
If AR-15 automatic rifles use 5.56mm caliber bullets for medium- and long-distance field combats, then firing range and ballistics performance are optimized, but recoil and noise levels increase compared to smaller caliber options
Solution Approach 1:
The barrel design allows dynamic switching between different caliber configurations based on the shooting scenario. Users can select the AR-15 barrel for long-range combat where maximum range is needed, or switch to the Ruger 10/22 barrel for close-range shooting where lower recoil and noise are preferable, making the rifle adaptable to different operational requirements
3Ease of operation
If Ruger 10/22 automatic rifles use 0.22 inch caliber bullets for private hunting with low recoil and noise, then ease of operation and manufacturing cost are improved, but firing range and bullet performance are limited compared to AR-15 caliber
Solution Approach 1:
The interchangeable barrel system enables dynamic adaptation to shooting purposes. For private hunting where low recoil and noise are advantageous, users can install the Ruger 10/22 barrel. For field combats requiring extended range, users can switch to the AR-15 barrel, thus optimizing the rifle's performance characteristics based on the specific application
4Manufacturing precision
If automatic rifle manufacturers precisely calculate and correct all part dimensions for each model, then manufacturing precision and durability are ensured, but the universality of parts and components is reduced, making it impossible for different models to use the same parts
Solution Approach 1:
The barrel is segmented into a barrel body and a removable barrel cap with standardized threading and positioning slots. This segmentation allows the barrel to be designed with universal mounting features that match the gun body's standardized interface, enabling precise manufacturing of individual components while maintaining interchangeability across different rifle configurations
Solution Approach 2:
The gun body incorporates universal threading and positioning slot designs that are consistent across different barrel types. This standardization allows precise manufacturing of each component while ensuring compatibility, so that AR-15 and Ruger 10/22 barrels can both be properly installed on the same gun body through precise dimensional control

AI summary
A gun device allowing replacement of barrels with different sizes, having a gun body, one end of the gun body has an opening. The opening outer edge has a threading and a positioning slot. The gun body connects with a first size barrel by connecting the threading with a lock. The gun device further comprising: a guide adapter, a second size barrel and a barrel key. The guide adapter has a positioning body, a projecting part, and a first groove, the projecting part alignment connects with the positioning slot. The second size barrel has a second groove, the first groove corresponding with the second groove.
