Firearm Valve Piston for Recoil Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current semi-automatic firearms require two separate pistons for handling different cartridge weights, leading to difficulties in handling, storage, and mounting, as well as significant kickback force during heavy cartridge use, causing user discomfort and potential damage.
Innovation Solution
A novel operating system that adjusts kickback force using a valve piston, valve spring, and valve adjustment nut, allowing for automatic discharge of excess gas through barrel bracket gas discharge holes, eliminating the need for piston replacement and reducing kickback force across varying cartridge weights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate pistons are used for lightweight and heavyweight cartridges, then the firearm can operate with different cartridge weights, but the handling and storage become difficult and the device complexity increases
Solution Approach 1:
The patent implements a universal piston design that can handle both lightweight and heavyweight cartridges through a single component. The piston is equipped with an adjustable valve mechanism that can regulate gas pressure to accommodate different cartridge power levels, eliminating the need for multiple specialized pistons while maintaining compatibility across cartridge types.
Solution Approach 2:
The piston incorporates an adjustable valve that changes the system parameters (gas pressure regulation) based on the cartridge type being used. By modifying the pressure regulation parameter rather than changing the entire piston component, the system achieves adaptability to different cartridge weights while using a single universal piston design.
2Reliability
If two separate pistons are used for different cartridge weights, then proper gas pressure regulation is achieved, but the storage and handling difficulty increases
Solution Approach 1:
The universal piston with integrated adjustable valve serves multiple functions: it maintains reliable gas pressure regulation while also simplifying storage and handling by eliminating the need to manage multiple separate piston components. The single-component design reduces the risk of loss or damage during storage and simplifies the replacement process.
Solution Approach 2:
The valve mechanism is extracted as an integrated component of the universal piston rather than requiring separate piston assemblies. This extraction and integration of the pressure regulation function into a single replaceable unit simplifies storage and handling while maintaining reliable pressure regulation across different cartridge types.
3Force
If a heavy charged piston is used for high pressure cartridges, then the recoil force is reduced, but the kickback force during heavy cartridge use causes significant blow on the user's shoulder
Solution Approach 1:
The adjustable valve mechanism changes the gas pressure parameter dynamically based on cartridge type. For heavyweight cartridges, the valve regulates to release excess gas pressure, preventing excessive kickback force from being transmitted to the user's shoulder while still utilizing the full power of heavy cartridges when appropriate.
Solution Approach 2:
The system converts the potentially harmful excessive gas pressure from heavy cartridges into a beneficial controlled force. The valve mechanism captures the excess pressure energy and releases it in a controlled manner through the barrel bracket gas discharge holes, transforming what would be harmful kickback into manageable operational force.
4Ease of operation
If a lightweight charged piston is used for low pressure cartridges, then the mechanism operation is enabled, but the kickback force during heavy cartridge use causes significant blow on the user's shoulder
Solution Approach 1:
The adjustable valve mechanism modifies the gas pressure parameter to match the cartridge type. When lightweight cartridges are used, the valve opens fully to allow maximum gas pressure for reliable mechanism operation. When heavy cartridges are used, the valve regulates to limit kickback force, protecting the user from excessive shoulder blow while still enabling mechanism operation.
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 system effectively reduces kickback force, ensuring comfortable shooting and preventing mechanism damage by adjusting pressure values without replacing pistons, enabling smooth operation with both lightweight and heavyweight cartridges.
Implementation Method 1
a spring regulation portion that transfers in a controlled manner the motion obtained by the operating gas pushing back the piston to the mechanism
Implementation Method 2
the powder gas pressure formed during the shot in the firearms such as rifle to be applied as a an unlocking force to the mechanism
