Gas Balloon Container With Perforated Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flight craft containers experience condensation issues due to temperature changes during ascent, which impede visibility and can cause water damage, and existing solutions may not adequately prevent condensation under varying ambient conditions.
Innovation Solution
A container design featuring three or more plates spaced apart, where at least one plate is airtight and others have strategically sized holes to allow gas flow and pressure equalization without convection, creating a gradual temperature and pressure gradient that reduces condensation likelihood.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If holes are provided in the container walls to equalize pressure, then pressure difference is resolved, but gas convection occurs causing condensation
Solution Approach 1:
The patent applies local quality by providing holes only in specific plates (outer plate and intermediate plate) rather than all plates, and by making the holes have specific dimensions that allow pressure equalization while preventing convection. This localized approach with specific hole characteristics resolves the contradiction between pressure equalization and condensation prevention.
Solution Approach 2:
The patent changes the parameter of hole size to a specific range that permits gas flow for pressure equalization but restricts convective flow. By carefully controlling the hole dimensions (area and size), the system achieves pressure balance without enabling the convection that leads to condensation.
2Object-affected harmful factors
If the container structure is reinforced to prevent condensation, then condensation is reduced, but weight and rigidity requirements increase
Solution Approach 1:
The patent segments the container wall into multiple plates (outer plate, intermediate plate, inner plate) with specific hole configurations. This segmentation creates pressure equalization zones that prevent condensation without requiring additional weight-bearing reinforcement, thus reducing overall container weight while maintaining condensation prevention.
3Stress or pressure
If a double layer structure with holes is used, then pressure equalization is achieved, but condensation may still form under varying ambient conditions
Solution Approach 1:
The patent enhances reliability by applying local quality differently across multiple plates rather than uniformly. The outer plate and intermediate plate have holes for pressure equalization, while the inner plate remains airtight to protect contents. This differentiated local quality approach ensures reliable condensation prevention under varying ambient conditions.
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
This design effectively minimizes condensation on the container walls, maintaining clear visibility and preventing water damage, while also reducing the overall weight and rigidity requirements of the container.
Implementation Method 1
one or more holes of a size that allows gas to flow in and out of two spaces within which the at least one plate is located
Implementation Method 2
the holes being sufficiently large to allow gas to flow in and out but not to allow convection of the gas
Implementation Method 3
air in contact with the wall cools and water vapor in the air changes to water, resulting in condensation whereby water vapor forms on the inside of the walls

AI summary
A container for a flight craft such as a gas balloon is provided. Part of the walls of the container is constituted of three separated plates. The first plate has one or more holes that causes gas to flow in and out of two spaces so that the pressure difference between a first space and a second space separated by the first plate is resolved but does not cause gas convection between those two spaces. As the flight craft ascends, a relationship T1<T2<T3<T4 occurs among the temperatures inside the first to a fourth space. The temperature gradient between the inside and outside of the container becomes less pronounced. Condensation is unlikely to form on any of the three plates. The first plate with the holes buffers the force that the second plate is subjected to due to a pressure difference between the inside and outside of the container.
