Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suppressor systems for firearms face challenges in securely coupling to muzzle brakes of varying diameters while ensuring compatibility and preventing unintended coupling, which can lead to noise reduction inefficiencies and safety issues.
Innovation Solution
A suppressor system with an inner core and muzzle brakes featuring specific bore diameters and coupling mechanisms, including protrusions and recesses, allows for coupling with brakes of equal or smaller diameters while preventing coupling with larger diameters, ensuring secure attachment and noise reduction through controlled gas expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the suppressor is designed to securely couple to muzzle brakes of varying diameters, then compatibility and adaptability are improved, but the risk of unintended coupling with incompatible brakes increases
Solution Approach 1:
The coupling mechanism employs asymmetric geometry where the protrusion on the suppressor has a specific shape and size that only fits into corresponding recesses on compatible muzzle brakes. This asymmetric design ensures that only brakes with matching dimensional parameters can be coupled, preventing unintended coupling while maintaining adaptability across compatible variants.
Solution Approach 2:
The coupling interface features localized dimensional variations in the protrusion and recess geometries that correspond to specific brake diameter ranges. Each suppressor variant has locally optimized coupling features designed for particular caliber ranges, allowing secure coupling only with brakes of compatible dimensions while rejecting incompatible ones.
2Adaptability or versatility
If the coupling mechanism allows interchangeability of suppressors with different brake diameters, then versatility is improved, but the complexity of the coupling system increases
Solution Approach 1:
The coupling mechanism is designed with universal features that allow a single suppressor design family to interface with multiple brake diameter variants. The protrusion and recess geometry follows a standardized pattern with scalable dimensional parameters, enabling one suppressor variant to potentially couple with multiple brake sizes while maintaining a consistent coupling interface architecture.
Solution Approach 2:
The coupling system utilizes parameter-based design where the fundamental geometry of the protrusion and recess remains constant, but specific dimensional parameters (such as diameter, length, and depth) are varied to accommodate different brake sizes. This allows interchangeability across calibers without requiring fundamentally different coupling mechanisms for each variant.
3Reliability
If the suppressor securely couples to the muzzle brake, then noise reduction effectiveness is improved, but the difficulty of removal and interchangeability is reduced
Solution Approach 1:
The coupling mechanism transitions from a loose fit to a secure locked position through a dynamic engagement process. The protrusion is designed to flex or deform slightly during installation, allowing initial insertion, then locks into place with positive engagement features that provide secure coupling. This dynamic behavior enables both secure attachment and controlled removal.
Solution Approach 2:
The coupling system incorporates preliminary alignment features such as tapered surfaces or guide edges on the protrusion and recess that automatically align the components during installation. This preliminary action facilitates easy insertion by guiding the suppressor into the correct position before the final locking engagement occurs, reducing the effort required for installation while maintaining secure coupling.

Function Achieved in This Case
The system effectively reduces noise by securely coupling to muzzle brakes of compatible diameters, minimizing noise and ensuring safety by preventing incompatible attachments, thus enhancing the suppressor's performance and usability across different firearm calibers.
Implementation Method 1
the expansion gas changes directions and expands over a larger distance and thus a longer period of time

AI summary
A suppressor system includes at least one inner core having a core bore defined therein, the core bore having a nominal core bore diameter. The inner core also includes a core-coupling portion. A plurality of muzzle brakes that each includes a bore having a nominal brake bore diameter. Each muzzle brake includes a brake-coupling portion. The inner core is configured to allow the brake-coupling portions of muzzle brakes having nominal brake bore diameters that are equal to or less than the nominal core bore diameter to couple to the core-coupling portion and to prevent the brake-coupling portions of muzzle brakes having nominal brake diameters that are greater than the nominal core diameter from coupling to the core-coupling portion.
