Compressed Air Gun Trigger Structure with Pressure Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compressed air guns face challenges in withstanding high pressures due to their complex gas path structure, leading to poor stability and limited shot speed, making them less powerful than firearms and prone to perishability.
Innovation Solution
A trigger structure for compressed air guns that includes a separated pressure lock and eject chamber with a piston and trigger assembly, allowing for full auto and semi-auto shooting modes by controlling air pressure and flow, ensuring the gun can only fire when the eject chamber is fully refilled, and featuring a bullet wheel for automatic bullet loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the gas path structure is made complicated to achieve higher shot speed, then the pressure requirement increases, but the structure becomes harder to withstand high pressure and causes poor stability
Solution Approach 1:
The gas path is segmented into distinct functional chambers: a pressure lock chamber for pressure control and storage, and an eject chamber for projectile ejection. This segmentation allows each chamber to be optimized for its specific function, enabling high pressure operation in the pressure lock chamber while maintaining structural stability in the eject chamber.
Solution Approach 2:
The pressure lock chamber acts as an intermediary between the compressed air source and the eject chamber. It mediates the pressure transmission, allowing the system to build and maintain high pressure without directly exposing the eject chamber structure to extreme pressure fluctuations, thereby improving overall structural stability.
2Power
If the pressure in the compressed air chamber is increased to improve power, then the structure becomes more prone to perishability
Solution Approach 1:
The compressed air chamber is divided into a pressure lock chamber that withstands high pressure and an eject chamber that operates at controlled pressure levels. This segmentation allows the system to achieve high power through pressure buildup while the pressure lock chamber is specifically designed to withstand the high pressures without structural failure.
Solution Approach 2:
The pressure lock mechanism provides beforehand cushioning by controlling the pressure release timing and rate. The pressure lock prevents sudden pressure drops that could cause structural shock and damage, allowing the system to operate at high pressures while protecting the overall structure from pressure-induced perishability.
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 solution enhances the stability and power of compressed air guns by allowing controlled high-pressure operation, enabling full auto and semi-auto modes while preventing firing until the chamber is refilled, thus maintaining efficiency and extending the gun's operational lifespan.
Implementation Method 1
a compressed air chamber which is connected with a compressed air supplier; the compressed air chamber is separated into at least a pressure lock chamber and an eject chamber
Implementation Method 2
the pressure lock blocks the air channel between the pressure lock chamber and the eject chamber pressed air when the gun is fired and then springs back to let air refill the eject chamber
Implementation Method 3
a piston which is sliding along the eject chamber, locked by a trigger assembly to block the outlet while not firing

AI summary
A compressed air gun trigger structure, the air refill lock cooperates with the trigger assembly to facility full auto and semi auto shooting. That is while the pressure of the eject chamber is lower than the set scale, the air refill lock will lock the piston even though the trigger is triggered by user. So the compressed air gun cannot be fired when the pressure is low. When the eject chamber is fully refilled and the pressure will push the air refill lock to releases the trigger and while user triggered the trigger, the compressed air gun is fired. That is the semi-auto mode. If the user keep holding the trigger, air refill lock will automatically trigger the piston for firing when the eject chamber is fully refilled. That is the full-auto mode.
