Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional pneumatic launch device with gradual gas pressure release is used, then the structure is simple, but the control over ejection pressure is insufficient leading to inconsistent drone deployment
Solution Approach 1:
The pressurization chamber is pre-filled with compressed gas before launch, and the temporary closing means is pre-positioned to seal the passage opening. This preliminary preparation allows for precise control of gas pressure buildup to a predetermined trigger pressure, ensuring consistent and reproducible ejection pressure without requiring complex real-time control systems.
Solution Approach 2:
The invention changes the physical state parameter of the gas from a gradual release process to an instantaneous release at a specific trigger pressure. By setting a predetermined trigger pressure and using temporary closing means that opens instantaneously when this pressure is reached, the system achieves precise control over ejection pressure while maintaining structural simplicity.
2Reliability
If compressed gas is gradually released behind the drone, then the device structure is simple, but the deployment speed and height cannot be reliably controlled
Solution Approach 1:
The invention replaces complex mechanical pressure control mechanisms with a pressure-sensitive temporary closing means that automatically opens when a predetermined trigger pressure is reached. This substitution uses the inherent properties of the pressure-sensitive component to achieve reliable and reproducible pressure control without requiring additional complex control systems.
Solution Approach 2:
The temporary closing means acts as a feedback mechanism that responds to the gas pressure in the pressurization chamber. When the pressure reaches the predetermined trigger pressure, the temporary closing means automatically opens, creating a closed-loop control system that ensures consistent ejection pressure and reliable drone deployment.
3Productivity
If safety margins are added to prevent drone contact with vehicle antennae, then contact avoidance is ensured, but the deployment distance increases reducing operational efficiency
Solution Approach 1:
By precisely controlling the ejection pressure through the predetermined trigger pressure mechanism, the invention achieves consistent and reliable drone deployment parameters. This allows for optimized ejection velocity that ensures safe clearance from vehicle antennae while minimizing the deployment distance, thereby maintaining high operational efficiency without requiring excessive safety margins.

AI summary
A device for pneumatic launching of a drone includes a launch tube, a pressurization chamber situated at the rear of the tube and provided with a passage opening leading into the tube, and a device for temporarily closing the passage opening. The temporary closing device is arranged to change from a closed configuration to an open configuration instantaneously under the action of the gas pressure inside said chamber, after the latter has reached a trigger pressure, and the cross section of the passage opening is sufficiently large that, instantaneously with the change to the open configuration, the gas pressure prevailing in the chamber and the space located behind the drone, then in communication with each other, is the desired launching pressure for the drone.
