Solution Overview

Problem

Current weather balloons lack the ability to maneuver laterally within the jet stream, leading to incomplete data collection and unpredictable jet stream paths, which affects weather prediction, transportation, and national security.

Innovation Solution

A lighter-than-air vehicle (LAV) equipped with an altitude movement device and an apparent wind generating device, such as a motorized propeller or drag balloon, to navigate laterally within the jet stream, combined with a three-vehicle control system for precise lateral movement and navigation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If weather balloons are used for jet stream navigation, then data collection is possible, but lateral movement control is lacking causing the vehicle to glide out of the jet stream path

Engineering Contradiction:
Improvejet stream data collectionVSAvoidlateral movement control
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the balloon's lateral position adjustable rather than fixed. The control system dynamically modifies the balloon's lateral movement characteristics by adjusting ballonet volume distribution, allowing the vehicle to actively track and remain within the jet stream path rather than passively drifting away.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes physical parameters of the balloon system, specifically the ballonet volume and its distribution, to control lateral movement. By varying these parameters, the system can generate lateral forces to counteract drift and maintain optimal positioning within the jet stream for continuous data collection.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the jet stream path is not accurately tracked, then weather prediction reliability decreases, but implementing lateral control increases device complexity

Engineering Contradiction:
Improveweather predictionVSAvoidcontrol system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control system operates autonomously using onboard sensors to detect jet stream position and automatic control algorithms to adjust ballonet volume. This self-service capability eliminates the need for complex external control infrastructure while maintaining reliable tracking, reducing overall system complexity despite enhanced functionality.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback control by continuously monitoring jet stream position via onboard sensors and automatically adjusting ballonet volume in response to detected position deviations. This closed-loop feedback mechanism ensures reliable jet stream tracking without requiring overly complex manual control systems.

Inventive Principle:
Principle #23Feedback

3Quantity of substance

If weather balloons rise and fall over a brief path, then some measurements are obtained, but most of the jet stream remains unmeasured

Engineering Contradiction:
Improvedata collection coverageVSAvoidtime in jet stream
Core Design Contradiction:
Quantity of substanceVSDuration of action of moving object

Solution Approach 1:

The patent enables continuous useful action by allowing the balloon to remain within the jet stream for extended periods through active lateral position control. Unlike traditional balloons that drift out and must be relaunched, this system continuously tracks the jet stream path, maximizing data collection duration and spatial coverage without interruption.

Inventive Principle:
Principle #20Continuity of useful action
