Evacuation Cabin Segmented Housing for Flood Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recreational vehicles and trailers are neither floatable nor water-sealable, making them inadequate as evacuation cabins during tsunami events, as they cannot protect occupants from flooding and may tip over in water.
Innovation Solution
A self-supporting evacuation cabin with an upper and lower housing sealed integrally and water-sealably, equipped with solar panels, ventilators, furniture, and a power source to maintain stability, and mounted on a chassis with wheels for mobility, featuring a water-sealable door system and reinforced construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional trailer or recreational vehicle is used, then it can provide temporary living conditions, but it is neither floatable nor water-sealable and cannot protect occupants from flooding
Solution Approach 1:
The evacuation cabin is divided into an upper housing and a lower housing that are sealed together. The lower housing acts as a floatation chamber while the upper housing provides living space, allowing the structure to be both water-sealable and floatable simultaneously.
Solution Approach 2:
The lower housing serves multiple functions: it provides structural support, creates buoyancy for floatability, and forms a water-tight seal with the upper housing. This multi-functional design resolves the contradiction between being land-based and water-adaptable.
2Adaptability or versatility
If a boat is used for evacuation, then it is floatable, but it is not water-sealable and runs a risk of overturn
Solution Approach 1:
By separating the floatation function (lower housing) from the living space (upper housing) and sealing them together, the design achieves both floatability and water-sealing, eliminating the risks associated with conventional boats.
3Reliability
If the evacuation cabin is designed to float, then it can withstand flooding, but the center of gravity may be too high causing instability
Solution Approach 1:
A power source is installed in the lower housing to act as a counterweight, lowering the center of gravity of the entire structure. This prevents the cabin from overturning while maintaining its floatation capability.
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
The evacuation cabin provides a safe, stable, and mobile shelter that can float above water, maintaining stability and protecting occupants from flooding, while allowing for temporary living conditions during emergencies.
Implementation Method 1
a power source acting as a weight to lower the center of gravity of the evacuation cabin so as to maintain the evacuation cabin in a stable condition when water floods the ground
Implementation Method 2
the upper housing and the lower housing are sealed integrally and water-sealably... the evacuation cabin can float above the ground

AI summary
An evacuation cabin includes an upper housing and a lower housing. The upper housing has a joining portion along a bottom edge of the upper housing and an opening at middle of one side of the upper housing for receiving an upper part of a water-sealable door. The lower housing has a joining portion corresponding and sealed to the joining portion of the upper housing such that the upper housing and the lower housing are sealed integrally and water-sealably, and an opening corresponding to the opening of the upper housing and for receiving a lower part of the water-sealable door. There are accommodated in the lower housing a power source acting as a weight to lower the center of gravity of the evacuation cabin so as to maintain the evacuation cabin in a stable condition when water floods the ground. A chassis, provided underneath the evacuation cabin, is mounted with an axle for installing wheels so that the evacuation cabin can stand stationary or be transported as a trailer by a mobile.
