Double Piston Pneumatic Weapon with Bidirectional Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air weapons, such as pneumatic and PCP systems, face issues with low target accuracy, high vibration during shooting, and the need for auxiliary equipment like compressors, which are cumbersome and time-consuming, leading to decreased shooting range and power. Additionally, they lack efficient safety mechanisms and adjustable fore-sight systems, resulting in reduced shooting precision and increased risk of accidents.
Innovation Solution
A high-power pneumatic weapon system with a double piston mechanism that allows bidirectional air compression, a safety mechanism positioned in front of the trigger for automatic locking, and multiple rotatable fore-sight configurations, using soft metals for the trigger and hammer with flexible buffers to absorb shocks, and a check valve mechanism for efficient air release, enabling high-speed shooting and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a single piston and unidirectional compression mechanism is used, then the device structure is simple, but high compression and shooting speed cannot be achieved
Solution Approach 1:
The single piston is divided into two pistons operating in opposite directions. The first piston compresses air during forward motion, while the second piston compresses air during backward motion, enabling bidirectional compression and achieving high shooting speed and power without requiring multiple pumping cycles.
2Strength
If tempered steel is used for trigger and piston mechanisms to ensure structural strength, then the strength is sufficient, but material processing becomes difficult and costs increase
Solution Approach 1:
The trigger and hammer components are made from zamac (a zinc-based alloy), which provides sufficient strength while being much easier to process and manufacture than tempered steel. The material allows for molding techniques that reduce manufacturing complexity and costs while maintaining the required mechanical properties.
Solution Approach 2:
The design changes the material parameter from high-strength tempered steel to zamac alloy, accepting a slight reduction in absolute strength but gaining significant improvements in manufacturability, cost, and ease of processing while maintaining adequate strength through proper structural design.
3Reliability
If the safety latch is positioned at the side of the weapon, then the safety mechanism is functional, but accessibility is difficult and user concentration is interrupted
Solution Approach 1:
The safety latch is repositioned from the side of the weapon to the front area near the trigger, changing its spatial location to a more accessible dimension. This allows the user to operate the safety latch with the same finger used to pull the trigger, eliminating the need to reach to the side and maintaining continuous concentration during shooting.
4Ease of manufacture
If long and right-angled air passages are used from compressed air housing to barrel, then the structure is straightforward, but friction losses reduce shooting range and power
Solution Approach 1:
The air passages are designed with curved paths instead of long right-angled turns. The curved passages reduce the length of the air path and minimize friction losses by eliminating sharp corners, thereby preserving air pressure and shooting power while maintaining structural simplicity.
5Device complexity
If a fixed fore-sight is used, then the structure is simple, but shooting accuracy decreases when air content in the tube varies
Solution Approach 1:
The fixed fore-sight is replaced with an adjustable fore-sight mechanism that can be rotated to different positions. This dynamic adjustment allows the shooter to compensate for variations in air pressure and content in the tube, maintaining shooting accuracy across different operating conditions without significantly increasing structural complexity.
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 achieves higher shooting accuracy and power with reduced vibration, eliminates the need for auxiliary equipment, and provides easy access to safety features, allowing continuous shooting with minimal adjustments, while preventing accidental trigger pulls and reducing the risk of accidents.
Implementation Method 1
The first one is the mechanism with spring and piston. It operates through the logic of activation of the weapon through the pull of trigger by a spring mechanism operating by the use of a lever or barrel at the side of the weapon as a crank. The air becoming highly compressed through the compression of high-volume air in front of the piston by activated spring mechanism reaches to the barrel and enables shooting pellets inside the barrel.
Implementation Method 2
The trigger and hammer are made of soft and easily available metals, such as zamac, and they have mechanism with spring and flexible buffer for the absorption of shocks occurred during the operation of these parts.
Implementation Method 3
The structure of double pistons being one in another allows for obtaining highly compressed air. Air weapons composed of spring and piston cannot be set up successively (air filling). Since they cause high vibration during shooting, the target accuracy is low.
Implementation Method 4
For pumping successively, there is a mechanism releasing the compressed air, which can challenge the system. The piston carries on compressing air while the upper body opens and closes.
