Barrel Mounting System Using Segmented Sleeve and Collar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms barrels often become damaged during conflicts or training, leading to compromised accuracy and potential misfires or explosions, and existing mounting systems are not efficient for quick adaptation to different environments or barrel changes.
Innovation Solution
A barrel mounting system comprising a mount receiver, barrel sleeve with threads, and barrel collar, which allows for easy installation and removal of barrels with limited expertise, enabling quick adaptation to diverse environments by securing the barrel to the firearm body using a mounting nut or clamp and adjustable sleeve insert.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional barrel mounting system is used, then the barrel is securely fixed to the firearm body, but the barrel exchange process becomes time-consuming and complex
Solution Approach 1:
The mounting system is divided into separate modular components: a mount receiver attached to the firearm body, a barrel sleeve that fits over the barrel, and a barrel collar. This segmentation allows each component to be independently assembled and disassembled, enabling rapid barrel exchange while maintaining secure fixation through the coordinated interaction of these modular elements.
Solution Approach 2:
The system incorporates dynamic adjustment capabilities through threaded connections and adjustable components. The barrel sleeve and collar can be rotated and positioned to different degrees, allowing the operator to quickly tighten or loosen the mounting mechanism during barrel exchange, thus reducing the time required while ensuring reliable fixation.
2Reliability
If a complex mounting system with multiple components is used, then the barrel can be securely mounted, but the system becomes difficult to operate and assemble
Solution Approach 1:
By dividing the mounting system into distinct segments (mount receiver, barrel sleeve, barrel collar), each with a specific function, the system becomes more manageable. The segmented design allows operators to work with smaller, simpler components individually rather than manipulating a complex integrated assembly, thereby improving ease of operation while maintaining mounting security.
Solution Approach 2:
The barrel sleeve is designed to fit over the barrel, and the barrel collar is positioned to engage with the sleeve and receiver. This nested arrangement of components creates a logical assembly sequence where each part fits into the previous one, simplifying the overall assembly process despite having multiple components, and making disassembly equally straightforward.
3Adaptability or versatility
If the firearm is adapted for different environments by modifying the barrel, then the weapon suits diverse conditions, but the adaptation process requires significant expertise and time
Solution Approach 1:
The mounting system enables dynamic reconfiguration of the firearm by allowing quick barrel exchanges without permanent modifications. Operators can adapt the firearm to different environments by simply replacing the barrel component rather than performing complex modifications, thereby maintaining high adaptability while reducing the perceived complexity through standardized interfaces and simplified assembly procedures.
4Productivity
If a quick-release mounting system is used, then barrel exchange is rapid, but the security and reliability of barrel fixation may be compromised
Solution Approach 1:
The segmented design with separate mounting components allows for a controlled release mechanism. The barrel sleeve and collar can be quickly disengaged from the receiver through a systematic sequence of actions, enabling rapid exchange while ensuring that each component maintains its structural integrity and fixation security during both mounted and exchanged states.

AI summary
A barrel mounting system to mount a barrel to a barrel mount of a firearm body includes a mount receiver secured to the barrel mount. The mount receiver includes axial channels and receiver threads disposed on an interior surface. The system further includes a barrel sleeve disposed around the barrel proximal to the proximal end of the barrel. The barrel sleeve includes sleeve threads disposed near a proximal end on an exterior surface and sized to slide through the axial channels and, when rotated, to engage the receiver threads. The system further includes a barrel collar disposed around the barrel and secured to the barrel and to limit the axial position of the barrel sleeve.
