Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compressed spring is used to drive the piston and launch the projectile, then the system can achieve projectile launch capability, but the system becomes prone to mechanical failure due to stresses applied by the compressed spring
Solution Approach 1:
The patent replaces the spring-based mechanical power source with a pneumatic system that uses compressed gas stored in an external reservoir. The gas is delivered through a valve and nozzle to propel the projectile, eliminating the compressed spring and its associated mechanical stresses and failure modes.
Solution Approach 2:
The invention implements a pneumatic launching system where compressed gas from an external reservoir is directed through a valve mechanism and nozzle to generate propulsive force on the projectile. This pneumatic approach replaces the mechanical spring system and provides a more reliable power source.
2Adaptability or versatility
If existing pneumatic launching systems are used, then projectile launch is achieved, but performance and usability shortcomings persist along with limitations in compatibility with common airsoft equipment
Solution Approach 1:
The patent designs a pneumatic launching system that can be adapted to various airsoft gun configurations (AEG, spring-powered, gas-powered) and operating modes (single-shot, semi-automatic, fully automatic). The modular design with standardized components enables broad compatibility across different airsoft equipment while maintaining consistent performance.
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
Enhances accuracy, usability, and durability by providing consistent gas supply and mechanical reliability, suitable for various airsoft gun configurations.
Implementation Method 1
a forward force is applied to the nozzle when the firing chamber is filled. As the surface area acting on the rear of the nozzle is greater than the surface area of the front, the nozzle moves to the forward position
Implementation Method 2
A nozzle biasing chamber at the front of the nozzle receives a constant supply of gas from the input port. This gas applies a constant rearward biasing force on a surface at the front of the nozzle
Implementation Method 3
Flow through the fill port is selectively controlled by the position of the firing valve. When the firing valve is in the rearward (cocked) position gas flows through the fill port into the firing chamber
Data Source
AI summary
A pneumatic assembly for a projectile launching system including a body defining a continuous bore. A nozzle is positioned within the bore adjacent the forward end of the body and is moveable between a rearward position wherein the nozzle facilitates passage of a projectile through a projectile port and a forward position wherein the nozzle blocks the projectile port to prevent passage of a projectile therethrough.
