Firearm Noise Suppressor With Nested Baffles And Rotated Notches
Solution Overview
Problem
Current noise suppressors for firearms are ineffective in reducing muzzle blast without increasing the size or weight, as larger baffle designs are required for better noise reduction but result in increased size and weight, compromising performance.
Innovation Solution
A noise suppressor design featuring a central axis with nested baffles, where the first and second baffles have double notches oriented 90 degrees relative to single notches in the remaining baffles, enhancing gas dissipation and minimizing muzzle blast without increasing size or weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the size of the baffle design is increased to reduce muzzle blast, then the noise reduction effectiveness is improved, but the size and weight of the noise suppressor increase
Solution Approach 1:
The baffle design is segmented into multiple individual baffles (first baffle, second baffle, third baffle, etc.) arranged in series within the suppressor body. Each baffle contains multiple notches that segment the gas flow path, allowing progressive dissipation of high-pressure gases through multiple stages rather than a single large chamber, thereby reducing noise without increasing overall suppressor size or weight.
Solution Approach 2:
The multiple baffles are nested within each other in a compact arrangement, with each subsequent baffle positioned inside or adjacent to the previous one. This nested configuration maximizes the gas expansion volume within a constrained external dimensions, allowing effective noise reduction while maintaining a compact suppressor size and weight.

This nested configuration maximizes the gas expansion volume within a constrained external dimensions, allowing effective noise reduction while maintaining a compact suppressor size and weight.
Solution Approach 2:
The baffles utilize radial notches that extend around the circumference of each baffle, creating three-dimensional gas flow paths. This radial dimension allows gases to expand and dissipate in multiple directions simultaneously, increasing the effective volume for noise reduction without proportionally increasing the linear length of the suppressor.
3Object-affected harmful factors
If traditional baffle designs are used, then the noise suppressor maintains simple structure, but the muzzle blast is not fully suppressed
Solution Approach 1:
The baffle design is segmented into multiple individual baffles (first baffle, second baffle, third baffle, etc.) arranged in series within the suppressor body. Each baffle contains multiple notches that segment the gas flow path, allowing progressive dissipation of high-pressure gases through multiple stages rather than a single large chamber, thereby reducing noise without increasing overall suppressor size or weight.
Solution Approach 2:
Each baffle is designed with specific local features including multiple notches at predetermined positions, alignment features, and sealing surfaces. These localized structural qualities enable each baffle to perform specific functions in the gas dissipation process while maintaining manufacturability and assembly simplicity through standardized components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively reduces muzzle blast by approximately 1.7 to 2.0 dB compared to traditional designs, maintaining performance without size or weight increments, as demonstrated by decibel measurements.
Implementation Method 1
a noise suppressor creates a significantly larger volume than exists in the firearm barrel. Noise suppressors can create this larger volume through a series of chambers, which are often referred to as 'baffles.' As the projectile exits the firearm barrel, high-pressure gases expand through the series of baffles, which reduces the noise from the muzzle blast.
Implementation Method 2
Each of a first and second baffle of the plurality of baffles may comprise a proximal end having a first or second aperture oriented along the central axis and aligned in a first orientation. A third baffle of the plurality of baffles may comprise a proximal end having a third aperture oriented along the central axis, where the third aperture is offset from the first and second apertures

AI summary
A noise suppressor design is provided that improves reduction of muzzle blast without increasing the size or weight of the noise suppressor. In various embodiments, a noise suppressor for a firearm might comprise a central axis and a plurality of baffles that each nests within adjacent baffles along the central axis. A first baffle and a second baffle of the plurality of baffles might each comprise a proximal end having a first/second aperture oriented along the central axis and a plurality of notches in the proximal end adjacent to the first/second aperture and aligned in a first orientation. A third baffle of the plurality of baffles might comprise a proximal end having a third aperture oriented along the central axis and a single notch in the proximal end adjacent to the third aperture and aligned in a second orientation that is 90 degrees relative to the first orientation.
