Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerological sondes have limited capability to provide detailed data on the intensity and strength of cyclonic storms, relying primarily on GPS-based location and movement data, which does not adequately capture turbulence and wind conditions.
Innovation Solution
An aerological sonde with a self-sustaining design featuring a sonde casing that forms the sole drag surface, equipped with gyroscopic and accelerometer sensors to measure turbulence and orientation, allowing it to freely migrate in atmospheric flows and accurately capture turbulence data without additional stabilizing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional aerological sondes use GPS-based location and movement data to measure storm conditions, then the device structure remains simple, but the measurement precision of turbulence and wind conditions is insufficient
Solution Approach 1:
The patent replaces GPS-based location tracking with direct physical measurement using a turbulence sensor (gyroscope and accelerometer) that measures the actual motion and orientation of the sonde itself. This substitution of mechanical sensing for satellite-based positional calculation enables direct turbulence measurement while maintaining reasonable device complexity.
Solution Approach 2:
The patent introduces a turbulence sensor as an intermediary measurement device that directly senses atmospheric turbulence through the sonde's motion response. The gyroscope and accelerometer act as intermediaries between the atmospheric conditions and the measurement system, providing direct turbulence data rather than deriving it from GPS position changes.
2Stability of the object's composition
If aerological sondes use additional stabilizing components like parachutes or balloons, then the stability of the sonde is improved, but the device complexity and additional drag increase
Solution Approach 1:
The patent employs the sonde casing itself to provide both structural protection and aerodynamic drag functions. The outer casing surface is designed to form the drag surface, eliminating the need for separate parachute or balloon components. This self-service approach maintains stability while reducing device complexity.
Solution Approach 2:
The sonde casing serves multiple functions simultaneously: it protects the internal electronics and measurement instruments, provides the aerodynamic drag surface for atmospheric interaction, and defines the overall structure of the device. This multi-functionality eliminates the need for separate stabilizing components.
3Productivity
If aerological sondes descend quickly to the surface, then the measurement time is reduced, but the productivity of data collection is improved
Solution Approach 1:
The patent optimizes the terminal velocity parameter of the sonde by designing the outer casing drag surface area and shape. By adjusting the drag coefficient and surface area relative to the sonde's mass, the terminal velocity is controlled to provide an optimal balance between measurement duration and productivity, allowing sufficient time for detailed turbulence measurements while maintaining efficient data collection rates.
