Compact Firearm Silencer With Retractable Third Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm silencers require large volumes to effectively suppress sound, leading to cumbersome designs that increase the length of the firearm and interfere with sight lines, necessitating a compact and space-saving solution that maintains sound suppression efficacy.
Innovation Solution
A compact firearm silencer with three longitudinal chambers, where the third chamber can retract into the second using a mechanical compression member, expanding to accommodate gases and then retracting to maintain a compact form factor, allowing for effective sound suppression without increasing the firearm's length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the internal volume of the silencer is increased to improve sound suppression, then the outer diameter becomes too large and interferes with sight lines
Solution Approach 1:
The silencer is divided into multiple longitudinal chambers (first chamber, second chamber, third chamber) that process gases in sequence. This segmentation allows the total internal volume to be distributed along the length of the silencer rather than requiring a large diameter single chamber, thus maintaining effective sound suppression while keeping the outer diameter compact and non-interfering with sight lines.
Solution Approach 2:
Instead of increasing volume by expanding the outer diameter (two-dimensional expansion), the invention extends the silencer in the longitudinal dimension. The multiple chambers are arranged end-to-end along the barrel axis, converting radial volume expansion into axial length extension, which preserves a compact outer diameter while achieving the necessary internal volume for sound suppression.
2Area of stationary object
If the outer diameter is reduced to improve compactness, then the silencer length must be increased which impacts the overall length of the firearm
Solution Approach 1:
The third chamber is designed with movable walls that can expand and retract dynamically. During normal operation, the chamber retracts to maintain a compact overall length. When gases need to be contained, the chamber expands to provide the necessary volume, thus achieving both compactness and adequate length when needed without permanently increasing the firearm's overall length.
3Object-affected harmful factors
If a fixed length chamber is used to suppress sound, then the silencer becomes too long and impacts the overall length of the firearm
Solution Approach 1:
The silencer employs dynamic chamber expansion and retraction mechanisms where the third chamber can extend when needed for sound suppression and retract to minimize overall length. This dynamic behavior allows the silencer to provide adequate sound suppression volume only when gases are present, rather than maintaining a permanently long fixed chamber, thus reducing the impact on the firearm's overall length.
Solution Approach 2:
The movable chamber walls are retracted into the body of the silencer after serving their purpose of containing and suppressing gases. This recovery mechanism allows the silencer to return to a compact state, discarding the extended length temporarily, thus maintaining a shorter overall length when sound suppression is not actively needed.
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 silencer achieves significant sound suppression comparable to larger designs while maintaining a compact form factor, enhancing the operability and maneuverability of the firearm, and can be mass-produced at lower costs.
Implementation Method 1
The mechanical compression member, such as a concentric spring, between the second and third chambers can be compressed to retract the third chamber into the second chamber
Implementation Method 2
Silencers (also known as suppressors) for firearms operate on the principles of converting a portion of this sound energy into heat energy by diverting or trapping the pressurized gas in chambers within the silencer body
Implementation Method 3
The pressurized gas is forced to expand into the spaces within the silencer, thereby decreasing the pressure, velocity and temperature of the gases prior to their release into the atmosphere or external environment

AI summary
A compact silencer (suppressor) device for a firearm comprising of multiple chambers which trap the gases from a projectile exiting the barrel of a gun to slow down the gases and reduce the temperature, sound, and flash associated with the projectile. In one embodiment, the first chamber which attaches to the barrel of the firearm comprises of sound baffling materials or gas porting baffles which vent gases from the second chamber passing rearward. The second chamber comprises of a chamber which can accommodate a retractable third chamber of the device, the second and third chamber of the device can have sound baffles to slow down the gases from the projectile.
