Frusto-Conical Baffle Ports for Firearm Suppressor Noise and Heat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm suppressors face issues with system heating, excessive combustion gas venting, and hearing protection, particularly in coaxial chambered designs that compromise on weight, strength, and component complexity.
Innovation Solution
The use of biconvex or lens-shaped ports on the peripheral edge of frusto-conical baffles in a cylindrical housing, which facilitates high-velocity gas flow and turbulence, reducing sound pressure and heat generation without the need for extraneous walls or complex coaxial chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If coaxial chambered designs are used to reduce sound pressure, then noise suppression is improved, but system weight and heat generation increase
Solution Approach 1:
The patent extracts the harmful coaxial chamber structure from the suppressor design. By eliminating the extraneous walls and coaxial chambers, the design reduces system weight while maintaining noise suppression through alternative means (baffle ports and turbulence generation).
Solution Approach 2:
The patent applies local quality by creating specific port geometries (biconvex, kidney-bean shaped, teardrop shaped) at critical locations on the baffles. These localized port designs generate turbulence and reduce sound pressure without requiring the complex coaxial chamber structure throughout the entire suppressor.
2Object-affected harmful factors
If coaxial chambered designs are used to reduce sound pressure, then noise suppression is improved, but system heating increases
Solution Approach 1:
The patent removes the extraneous walls and coaxial chambers that trap heat within the suppressor. By extracting these heat-trapping structures, the design allows for better heat dissipation while maintaining noise suppression through the baffle port system.
Solution Approach 2:
The patent uses locally optimized port geometries on the baffles that generate turbulence to reduce sound pressure without creating the heat-trapping coaxial chamber environment. The ports are strategically positioned and shaped to achieve noise reduction without the associated thermal problems.
3Weight of moving object
If conventional baffle porting is used to reduce weight, then system weight is reduced, but sound pressure reduction is insufficient
Solution Approach 1:
The patent applies local quality by implementing specific port geometries (biconvex, kidney-bean shaped, teardrop shaped) at critical locations on the baffles. These localized port designs generate turbulence and reduce sound pressure more effectively than conventional porting, achieving better noise suppression without adding significant weight.
Solution Approach 2:
The patent changes the geometric parameters of the baffle ports from conventional circular or rectangular shapes to optimized curves (biconvex, kidney-bean, teardrop). These parameter changes in port geometry create more effective turbulence and sound pressure reduction while maintaining lightweight construction.
4Device complexity
If simple baffle design is used to reduce complexity, then device complexity is reduced, but hearing protection is insufficient
Solution Approach 1:
The patent uses local quality by implementing specific port geometries at critical locations on the baffles. This approach provides effective hearing protection through localized turbulence generation rather than requiring complex coaxial chambers and extraneous walls throughout the entire suppressor structure.
Solution Approach 2:
The patent changes the geometric parameters of the baffle ports to optimized shapes that generate effective turbulence for hearing protection. These parameter changes in port geometry provide superior noise reduction compared to simple conventional porting, achieving better hearing protection without proportionally increasing device complexity.
