Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm suppressors are inadequate in effectively reducing the energy and noise of exhaust gases, as they rely on simple baffle designs that do not fully dissipate the energy of high-speed exhaust gases, leading to incomplete sound suppression and flash reduction.
Innovation Solution
The design incorporates a baffle assembly with conical sections, expansion surfaces, and ports that dissipate energy by creating expansion and compression effects through alternating convex and concave corners, and an end cap assembly with multiple exit paths to further reduce pressure and turbulence, thereby enhancing sound suppression and flash reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple baffle designs are used in suppressors, then the device complexity is reduced, but the energy dissipation effectiveness of exhaust gases deteriorates
Solution Approach 1:
The suppressor is divided into multiple expansion chambers separated by baffle walls with multiple ports. Each chamber segment independently dissipates exhaust gas energy through its own set of expansion surfaces and ports, creating a staged energy reduction process that is more effective than a single-chamber design while maintaining manageable complexity.
Solution Approach 2:
The baffle walls incorporate curved expansion surfaces with specific radii of curvature. These curved surfaces create controlled expansion of exhaust gases as they pass through the suppressor, utilizing fluid dynamics principles to dissipate energy more effectively than flat surfaces while adding minimal structural complexity.
2Ease of manufacture
If conventional baffle designs are used, then the manufacturing process is simplified, but the sound suppression effectiveness deteriorates
Solution Approach 1:
The baffle walls are designed with pre-calculated expansion surface geometries and port configurations that optimize sound suppression before the exhaust gas enters the suppressor. The expansion surfaces are positioned and dimensioned to create specific flow patterns that maximize noise reduction, allowing the baffles to be manufactured as precision components that deliver predictable acoustic performance.
Solution Approach 2:
The suppressor design utilizes specific geometric parameters including expansion surface radii, port diameters, and chamber volumes that are optimized to reduce sound pressure levels. By carefully controlling these parameters during manufacturing, the suppressor achieves effective sound suppression while maintaining manufacturability through standardized dimensional specifications.
3Device complexity
If simple expansion chambers are used, then the device structure is simplified, but the flash reduction effectiveness deteriorates
Solution Approach 1:
The suppressor design extends the exhaust gas path in the radial dimension through multiple expansion chambers arranged in series. Exhaust gases are forced to expand and change direction multiple times as they pass through each chamber, increasing the path length and time for energy dissipation without significantly increasing the axial length of the suppressor, thereby reducing flash intensity while maintaining compact structure.

AI summary
A suppressor baffle and a firearm suppressor for suppressing the volume of the report of a firearm includes a fitting for mounting the suppressor on a firearm, a sleeve, and a baffle assembly. The sleeve is supported by the fitting. The baffle assembly is at least partially received in an internal volume defined by the sleeve. A first baffle in the plurality of baffles has a conical section with a proximal opening and a port. The port is elongate in a direction along the circumference of the conical section. The port provides a fluid path through the conical section from an entrance chamber of the suppressor to an internal conical volume defined by the conical section. Gas flowing along the first baffle is directed through the port, causing energy dissipation in the gas.
