Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-altitude balloons used for weather prediction and communications tend to drift due to cross winds, limiting their mission duration within a designated geographic region.
Innovation Solution
A system and method that includes a high-altitude balloon with a control system to determine and adjust its altitude based on environmental parameters, maximizing the time it remains within a specific geographic area by compensating for wind velocity and direction changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the balloon is launched to a fixed initial mission optimum altitude, then the balloon can reach a high altitude quickly, but the balloon drifts out of the designated geographic region due to cross winds
Solution Approach 1:
The patent implements dynamic altitude adjustment by continuously monitoring wind conditions and modifying the balloon's altitude in real-time. The control system adjusts the balloon's vertical position to exploit vertical wind shear, changing the balloon's characteristics from static to dynamic to counteract cross-wind drift and extend mission duration within the designated geographic region.
2Device complexity
If the balloon remains at a constant altitude, then the control system is simple, but the balloon cannot compensate for wind velocity and direction changes
Solution Approach 1:
The patent employs a feedback control system that continuously monitors wind velocity and direction, balloon position, and altitude. This feedback information is processed to generate control commands that adjust the balloon's altitude, creating a closed-loop system that maintains reliable position within the designated region while adapting to changing wind conditions.
3Duration of action of moving object
If the balloon descends to counteract cross winds, then the balloon can remain in the geographic region longer, but the mission life is limited by the balloon's maximum altitude capability
Solution Approach 1:
The patent utilizes parameter changes by modifying the balloon's altitude parameter in response to wind conditions. By changing altitude rather than relying solely on temperature adjustments or payload weight changes, the system exploits the vertical dimension to counteract cross-wind drift, thereby extending the time the balloon remains within the designated geographic region.
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
The system effectively extends the mission duration of high-altitude balloons by optimizing their altitude to counteract wind effects, ensuring they remain within the designated region for longer periods.
Implementation Method 1
Balloons are filled with a highly buoyant gas (e.g., helium) that allows the balloon to ascend to a maximum altitude
