Flight Craft Container With Elastic Restraining Cage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Airtight containers used in flight craft that ascend to high altitudes face challenges in maintaining structural integrity due to significant pressure differences between the internal and external environments, which can lead to wall cracking if the container walls are not sufficiently strong.
Innovation Solution
The implementation of a container design featuring a main body that is airtight and a restraining member with a cage-like structure made of an elastic material, which adjusts to counteract the inward-to-outward force caused by pressure differences, thereby maintaining the structural integrity of the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the container walls are made thin to reduce weight, then the weight of the container is reduced, but the container cannot withstand the pressure difference between internal and external environments at high altitudes
Solution Approach 1:
The container is divided into two functional parts: a thin-walled main body for weight reduction and a separate restraining member (cage-like structure) for providing strength. The restraining member consists of multiple reinforcing ribs that are segmented and distributed across the container surface, creating a composite structure that combines the advantages of both thin walls and strong reinforcement.
Solution Approach 2:
The container employs a composite structure combining the main body wall and the restraining member with reinforcing ribs. This composite design allows the thin-walled main body to maintain low weight while the restraining member provides the necessary mechanical strength to withstand pressure differences, achieving both weight reduction and structural integrity.
2Strength
If the container walls are made thicker to withstand pressure difference, then the strength is improved, but the weight of the container increases
Solution Approach 1:
Instead of uniformly thickening the entire container wall, the reinforcement is segmented into discrete reinforcing ribs that are strategically positioned on the restraining member. This segmentation allows strength to be concentrated only where needed to withstand pressure loads, rather than distributing unnecessary material throughout the entire structure.
Solution Approach 2:
The reinforcing ribs on the restraining member provide localized strength enhancement at critical areas of the container. The main body walls remain thin with uniform thickness, while the restraining member introduces localized reinforcement only where structural support is required, optimizing the distribution of material for both weight efficiency and strength.
3Reliability
If an airtight container ascends to high altitude, then the internal environment can be maintained close to ground-level conditions, but the pressure difference between inside and outside causes significant force on the container walls
Solution Approach 1:
The restraining member with reinforcing ribs acts as a counterbalancing structural element that resists the outward force generated by the pressure difference. The ribs are designed to withstand and distribute the compressive and tensile forces acting on the container, providing mechanical counteraction to the pressure differential that arises from maintaining internal environment stability at high altitudes.

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 counteracts the pressure differences, ensuring the container's walls can withstand the forces without cracking, thus maintaining the airtightness and structural integrity of the container at high altitudes.
Implementation Method 1
a restraining member made of an elastic material having a cage-like structure and arranged to cover the main body; wherein the restraining member restrains a wall of the main body to generate a force that counteracts an inward to outward force that acts on the main body due to a difference between an internal and external pressure during flight

AI summary
A container for a flight craft is provided and comprises a main body that contains air and is airtight against an external space, and a restraining member having a cage-like structure and arranged to cover the main body, wherein the restraining member restrains a wall of the main body to generate a force that counteracts an inward to outward force that acts on the main body due to a difference between an internal and external pressure during flight. The flight craft may further comprise an adjusting mechanism that adjusts a length of a portion of the restraining member. The restraining member may be made of an elastic material.
