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 sound suppression solution that maintains operational effectiveness.
Innovation Solution
A compact firearm silencer with three longitudinal chambers, where the third chamber can retract into the second using a spring, expanding to accommodate gases and then retracting, allowing for controlled venting and maintaining a compact form factor while providing effective sound suppression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the internal volume of the silencer is increased to suppress more sound, then the outer diameter becomes too large and interferes with sight lines
Solution Approach 1:
The silencer employs a telescoping inner tube that can be inserted within the outer tube, creating a nested configuration. This nesting arrangement allows the silencer to achieve a larger internal volume for effective sound suppression while maintaining a compact outer diameter that does not interfere with the firearm's sight lines. The inner tube contains acoustic treatment materials and gas porting structures that are nested within the outer tube's interior surface.
Solution Approach 2:
The invention transitions from a conventional single-dimensional cylindrical design to a multi-dimensional telescoping structure. The inner tube can extend axially from the outer tube to increase internal volume when needed, and retract to minimize overall length. This dimensional flexibility allows the silencer to adapt its volume and length based on operational requirements without compromising sight lines or sound suppression effectiveness.
2Area of stationary object
If the outer diameter is reduced to avoid interfering with sight lines, then the silencer length increases and impacts the overall length of the firearm
Solution Approach 1:
The silencer incorporates a dynamic telescoping mechanism where the inner tube can extend and retract relative to the outer tube. This dynamic structure allows the silencer to change its effective length and internal volume based on operational needs. When the inner tube is retracted, the silencer maintains a compact length that does not impact the overall firearm length, while still providing sufficient internal volume for sound suppression through the nested acoustic treatment structures.
3Object-affected harmful factors
If a fixed length chamber is used to suppress sound, then the silencer can effectively contain gases, but the overall length becomes too long
Solution Approach 1:
The telescoping inner tube is nested within the outer tube, with both containing acoustic treatment materials and gas porting structures. This nested configuration allows the silencer to provide effective sound suppression through multiple chambers and acoustic pathways while maintaining a compact overall length. The inner tube's telescoping capability further reduces the extended length when retracted, eliminating the need for an excessively long fixed chamber.
4Ease of manufacture
If conventional concentric cylindrical suppressors are used, then manufacturing is straightforward, but the design is cumbersome and interferes with sight lines
Solution Approach 1:
The telescoping inner tube and outer tube are manufactured as separate concentric cylindrical components using conventional manufacturing processes. The inner tube is then inserted into the outer tube and secured using standard fastening methods such as rivets, welds, or interference fits. This nested construction approach maintains manufacturing simplicity while achieving a compact outer diameter that does not interfere with sight lines, as the nested configuration maximizes internal volume utilization.
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 length, enhancing the maneuverability and operability of the firearm, and allowing for mass production at lower costs.
Implementation Method 1
A compact firearm silencer with three longitudinal chambers, where the third chamber can retract into the second using a spring
Implementation Method 2
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
