Gas Projectile Platform Trigger Spool Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional gas-powered paintball guns lack consistency in pressure for ejecting projectiles due to trigger actuation, leading to suboptimal pressure leakage when the trigger is partially depressed.
Innovation Solution
A gas gun projectile platform with a rotating trigger, a first spool biased against a magnet, and a pad assembly that allows pressure to be transferred to a second spool to overcome spring force, ensuring consistent pressure for projectile ejection by releasing the bolt pressure area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional trigger actuation is used, then the gun can be operated, but the pressure for ejecting the projectile becomes inconsistent and leaks when the trigger is partially depressed
Solution Approach 1:
The trigger system is segmented into multiple functional components: a trigger member, a spool member, a valve member, and a magnet member. Each component performs a specific function in the pressure control sequence, allowing the system to decouple the trigger actuation from direct pressure release and instead use a staged mechanism that ensures consistent pressure delivery regardless of trigger pressure variations
Solution Approach 2:
The spool member acts as an intermediary between the trigger and the valve member. When the trigger is actuated, it moves the spool member, which in turn actuates the valve member to release pressure. This intermediary mechanism filters out variations in trigger pressure and ensures that a consistent amount of pressure is released for projectile ejection
2Productivity
If pressure is used to actuate the trigger, then the trigger can be activated, but the pressure leaks and becomes suboptimal for projectile ejection
Solution Approach 1:
The system performs preliminary actions by using the trigger actuation to sequentially position the spool member and then actuate the valve member before the actual pressure release occurs. This staged preliminary action ensures that pressure is not lost through premature or partial release, and that the full pressure is delivered efficiently to the projectile for optimal ejection

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides consistent pressure for ejecting projectiles independently of trigger pressure, ensuring reliable and efficient projectile ejection by separating the first spool from the magnet and positioning the second spool rearward to release stored pressure in the bolt area.
Implementation Method 1
a first spool biased against a magnet
Implementation Method 2
the second spool is configured to be positioned rearward overcoming a spring force
Implementation Method 3
an ejection pressure stored in a bolt pressure area is transmitted to a chamber and ejects a projectile from a barrel
