Firearm Sound Suppression Cover for Marking Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sound suppression devices for firearms suffer from degradation of markings on the outer tube due to hot discharge gases and sparks, which causes serial numbers and manufacturer's information to become unreadable or obliterated over time.
Innovation Solution
A sound suppression device with a cover system that includes a pair of longitudinal beams and cover plates or a tubular member to protect the outer tube from hot gases and sparks, preventing direct contact and thus preserving the markings, and allowing for easy cleaning or replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the outer tube is directly exposed to the expansion chambers, then the sound suppression device can be simpler in structure, but the markings on the outer tube will degrade and become unreadable due to hot gases and sparks
Solution Approach 1:
A cover is introduced as an intermediary component between the expansion chambers and the outer tube. The cover protects the outer tube from direct exposure to hot gases and sparks, preventing marking degradation while maintaining structural simplicity. The cover can be easily removed for cleaning or replacement without complicating the overall device structure.
2Reliability
If the outer tube is protected from hot gases, then the markings remain intact, but the device requires additional components to achieve this protection
Solution Approach 1:
The cover serves as a simple intermediary component that provides protection without adding significant complexity. It is designed to be easily installed and removed, allowing for maintenance without requiring complex disassembly procedures.
Solution Approach 2:
The cover is designed as a separate, removable component that can be easily detached from the inner core. This segmentation allows the cover to be independently maintained, cleaned, or replaced without affecting the rest of the sound suppression device, thereby minimizing the impact of added complexity.
3Ease of repair
If the cover is made removable for cleaning, then maintenance becomes easier, but the mounting structure becomes more complex
Solution Approach 1:
The cover is designed as a separable component with a simple mounting structure that allows easy removal and reinstallation. The mounting structure uses basic features such as pockets defined by recessed surfaces on the inner core, enabling straightforward assembly and disassembly without complex fastening mechanisms.
Solution Approach 2:
The cover is designed to be easily removable and reinstallable by the user without requiring specialized tools or procedures. This self-service design enables users to perform routine cleaning and maintenance tasks independently, improving ease of repair while keeping the mounting structure simple.
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 cover system effectively shields the outer tube from degradation, maintaining the integrity of markings and facilitating maintenance, while ensuring effective noise suppression and spark reduction.
Implementation Method 1
The expansion chambers enable discharge gases produced by firing the firearm to expand and cool, thereby suppressing noise and sparks
Implementation Method 2
The cover protects the outer tube from the hot gases and sparks generated by the firing

AI summary
A sound suppression device for a firearm includes an inner core and an outer tube surrounding the inner core. The inner core defines a central chamber extending the length of the inner core and has axially spaced baffles that define expansion chambers in fluid communication with the central chamber that enable hot gases generated by the firearm to expand and cool. A cover disposed between the outer tube and the inner core closes the expansion chambers and separates the expansion chambers from the outer tube.
