Aircraft Insulating Bag Drainage for Faster Humidity Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft insulation materials, such as glass wool, retain water due to humidity, leading to increased weight and prolonged drying times, which affects fuel consumption and CO2 emissions.
Innovation Solution
An insulating bag with a drainage system in the bottom region and a discharge that pierces through the packaging foil, allowing efficient water removal via a discharge, reducing water collection and drying time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If holes are made into the reinforced foil to remove water, then water can be removed from the insulation material, but water collects in the bottom region below the holes and drying time is prolonged
Solution Approach 1:
The invention transitions from point-based water removal (holes) to a linear drainage path (groove leading to discharge). The groove creates a one-dimensional channel that guides water from the bottom region to the discharge, eliminating water accumulation pockets and significantly reducing drying time while maintaining effective water removal.
Solution Approach 2:
The groove acts as an intermediary element between the insulation material and the discharge. It collects water from the bottom region and transports it to the discharge, preventing water accumulation and enabling efficient, continuous drainage without prolonged drying times.
2Quantity of substance
If a plurality of holes are made through the packaging foil for humidity removal, then water can be removed from the insulation material, but holes allow additional humidity to enter the insulation material
Solution Approach 1:
The invention extracts the drainage function from multiple discrete holes and consolidates it into a single integrated discharge system with a groove. This single discharge location performs both water removal and humidity blocking functions, eliminating the harmful effect of multiple holes allowing humidity entry while maintaining effective water drainage.
3Quantity of substance
If water collects in the bottom region of the insulating bag, then the insulation material retains moisture, but this increases weight and fuel consumption
Solution Approach 1:
The groove is pre-formed in the packaging foil during manufacturing, creating a ready-made drainage pathway before the insulating bag is put into service. This preliminary structural preparation ensures that water is immediately directed to the discharge upon condensation, preventing weight increase from water accumulation during flight operations.
