Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms produce loud noises during operation, posing a hearing damage risk to operators and enabling detection of their presence and location, necessitating suppressors that reduce the audible signature.
Innovation Solution
A firearm suppressor assembly comprising a mount body, core, and tube with baffles that form chambers to dissipate kinetic energy and reduce blast intensity, achieving a peak sound level below 136.62 dB as measured by MIL-STD-1474D.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a suppressor is designed to reduce peak sound pressure level, then hearing protection is improved, but the audible signature reduction may compromise operational detection capabilities
Solution Approach 1:
The suppressor divides the internal volume into multiple discrete chambers separated by baffles with specific aperture patterns. This segmentation allows different frequency ranges to be managed in different chambers, reducing peak sound pressure while maintaining low-frequency acoustic cues that preserve audible signature for operational detection.
Solution Approach 2:
Different portions of the suppressor interior have different baffle configurations and aperture densities tailored to specific frequency ranges. The proximal, intermediate, and distal chambers each have optimized local structures that selectively attenuate harmful high-frequency noise while preserving beneficial low-frequency signature characteristics.
2Object-affected harmful factors
If baffle structures are added to reduce blast intensity, then sound level is decreased, but device complexity increases
Solution Approach 1:
The baffle system is segmented into multiple standardized chambers with repeating geometric patterns. Each chamber uses similar baffle designs with varying aperture configurations, allowing modular manufacturing and assembly while achieving progressive blast intensity reduction across the length of the suppressor.
Solution Approach 2:
The suppressor employs composite construction with a titanium alloy outer shell and internally integrated baffle structures made from heat-resistant alloys. This composite approach reduces overall weight while maintaining the structural integrity needed to contain high-pressure blast waves without requiring excessive material thickness.

AI summary
A suppressor for a firearm is disclosed. The suppressor may have a first longitudinal axis and include a mount body for receiving a muzzle of a firearm barrel. The mount body may include a first proximal end, a first distal end spaced from the first proximal end along the first longitudinal axis, a collar adjacent to the first proximal end, and an annular stem adjacent to the first distal end. The annular stem may include a first outer side wall surface which comprises a first screw thread, and a first interior side wall surface which comprises a second screw thread. The suppressor further may include a core connected to the mount body, and a tube disposed over the core and the annular stem. The mount body, core, and tube may form a plurality of chambers for sound signature reduction of a host firearm.
