Artillery Shell Camera Descent via Pneumatic Balloon
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shell-type monitoring apparatuses face limitations in achieving wide-angle reconnoitering and prolonged operational time, especially when used for military or topographical photography, as they often experience sudden falls due to lack of controlled descent mechanisms.
Innovation Solution
The apparatus incorporates a gas storage system with a variable volume portion and a moving flow path to slowly lower and rotate a photographing unit, allowing for extended data collection from various angles without electrical power, using a gas supply to move the unit along the body's surface and a guide system for controlled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the photographing unit is lowered quickly to complete data collection faster, then productivity is improved, but reliability deteriorates due to sudden falls causing accidents
Solution Approach 1:
The patent uses a gas storage unit connected to a balloon through a flow path to provide controlled pneumatic pressure. The gas expands the balloon gradually, which in turn slowly lowers the photographing unit through the side surface of the shell-type monitoring apparatus. This pneumatic mechanism enables controlled descent that prevents sudden falls while maintaining operational efficiency.
2Adaptability or versatility
If the photographing unit is rotated to cover more angles, then adaptability is improved, but device complexity increases due to additional moving mechanisms
Solution Approach 1:
The patent employs gas expansion from the gas storage unit to rotate the photographing unit. The gas flows through the moving flow path and expands the balloon, creating rotational movement that positions the photographing unit at different angles. This pneumatic rotation mechanism achieves wide-angle reconnoitering capability while maintaining relatively simple device structure compared to traditional motorized systems.
