Solution Overview

Problem

Strong winds during inclement weather cause contortion and damage to rawinsonde balloons when helium is injected, leading to increased observational costs and manpower requirements due to the inability to reuse damaged balloons.

Innovation Solution

A rotating gas injection device featuring a handgrip, gas injection tube, ball bearing module, and outer ring cover that allows the neck of the balloon to make tight contact with the outer ring and cover, enabling rotation and preventing contortion by using the gas injection tube as a rotation axis, thereby reducing damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If gas is injected into the rawinsonde balloon during inclement weather, then the balloon can be inflated and used for observation, but strong winds cause the balloon to rotate and contort, leading to damage

Engineering Contradiction:
Improveobservation capabilityVSAvoidballoon integrity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent introduces a protective device as an intermediary between the wind environment and the balloon neck. This device includes a cylindrical protective cover with a guide groove that allows controlled rotation while preventing uncontrolled twisting of the balloon neck, thus mediating the harmful effects of wind-induced rotation

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The protective device incorporates dynamic elements including a rotatable cylindrical cover with guide grooves that enable controlled rotation. The structure transitions from a static protective cover to a dynamic system that can rotate with the balloon while maintaining protection, allowing the balloon to respond to wind forces without suffering damage

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If the rawinsonde balloon is damaged due to contortion, then the balloon cannot be reused, but this increases observational costs and manpower requirements

Engineering Contradiction:
ImprovereusabilityVSAvoidoperational cost
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The protective device is applied beforehand to cushion the balloon neck from wind-induced contortion forces. The cylindrical cover with guide grooves prevents excessive twisting before it can cause damage, enabling the balloon to withstand inclement weather conditions and be reused for subsequent observations

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A rotating gas injection device for preventing damage to a rawinsonde balloon, comprising: a handgrip part; a gas injection tube; a ball bearing module including an inner ring, an outer ring, wherein the inner ring and the outer ring are rotatably engaged by means of the balls; and an outer ring cover positioned outside of the outer ring to form space between the outer ring cover and the outer ring; wherein, after an insertion of a neck of the rawinsonde balloon into the space, a distance between the outer ring and the outer ring cover is controlled to be decreased so that the neck of the rawinsonde balloon makes tight contact, and in response to an external force exerted on the neck of the rawinsonde, the outer ring is allowed to be rotated together with the neck by means of the balls.
