Integrated Barrel Muzzle Device System with Interchangeable Projectile Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm sound suppressors often require additional weight and modifications to the barrel, and may not effectively suppress recoil and muzzle blast across different caliber projectiles, limiting their versatility and effectiveness.
Innovation Solution
The Integrated Barrel and Muzzle Device System features an interchangeable projectile tube and suppressor elements with open cell metal foam or 3D printed digital metal foam, which channels propellant gases through a high surface area, low mass, circuitous pathway to attenuate sound and reduce recoil, and can be adapted for various calibers without increasing barrel diameter or weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional sound suppressors are attached to the muzzle, then hearing protection and noise reduction are improved, but the firearm's weight increases and center of gravity changes
Solution Approach 1:
The suppressor is merged with the barrel to form an integrated assembly, eliminating the need for separate attachment hardware and reducing overall weight. The suppressor becomes an integral part of the barrel structure rather than a detachable accessory.
Solution Approach 2:
The integrated suppressor-barrel assembly is designed to accommodate multiple calibers through interchangeable insert tubes, making it universally applicable across different firearm configurations without requiring separate suppressors for each caliber.
2Object-affected harmful factors
If suppressors are designed for specific calibers, then sound suppression effectiveness is improved, but versatility across different calibers deteriorates
Solution Approach 1:
The suppressor is segmented into a main body and interchangeable insert tubes. Each insert tube is designed for a specific caliber, allowing users to swap tubes while keeping the main suppressor body. This segmentation enables caliber-specific optimization while maintaining overall suppressor versatility.
Solution Approach 2:
The suppressor system transitions from a static, caliber-specific design to a dynamic, interchangeable system. The ability to swap insert tubes allows the suppressor to adapt its internal geometry and gas channeling characteristics to match different caliber requirements, optimizing performance for each caliber while maintaining a single main suppressor body.
3Adaptability or versatility
If barrel diameter is increased to accommodate different calibers, then caliber versatility is improved, but device weight and manufacturing complexity increase
Solution Approach 1:
The interchangeable insert tubes are nested within the main suppressor body. Each insert tube contains the gas channels and internal geometry specific to a caliber, while the main suppressor body provides the external structure and mounting interface. This nesting approach allows multiple calibers to be accommodated within a single suppressor exterior, avoiding the need to manufacture multiple barrel diameters.
