Off-Grid Mobile House Structure With Ground Screw Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional houses utilizing renewable energy still have a significant ecological footprint due to the need for extensive infrastructure installation, such as potable water networks, sewerage systems, and electricity connections, which disrupts the environment.
Innovation Solution
A mobile house design that uses ground screws for support, integrating renewable energy systems like solar cells, rainwater harvesting, and waste water treatment, allowing for off-grid operation without disturbing the environment, thus eliminating the need for conventional utility connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional houses are connected to public utility infrastructures (potable water network, sewerage network, electricity network), then the house can access essential services, but the environment is substantially altered and disturbed through founding, laying pipes, and digging
Solution Approach 1:
The mobile house generates its own electricity through solar panels, filters and stores its own water through onboard filtration systems, and manages waste through compact treatment units. This self-sufficiency eliminates the need for connections to external utility networks, allowing the house to operate independently without disturbing the environment through infrastructure installation
Solution Approach 2:
The utility systems are divided into modular, self-contained units that can be integrated into the mobile house structure. Instead of requiring continuous external infrastructure, each utility function (energy, water, waste) is segmented into independent systems that operate autonomously within the house
2Adaptability or versatility
If the house is designed as a permanent structure with infrastructure connections, then utility access is ensured, but the house cannot be easily relocated and leaves a permanent ecological footprint
Solution Approach 1:
The house is designed with dynamic characteristics, being mobile and relocatable rather than fixed. The supporting structure uses ground screws that can be installed and removed without permanent damage to the ground, allowing the house to be moved to different locations while maintaining structural integrity and functionality
Solution Approach 2:
The house transitions from a static, permanently connected structure to a mobile, self-sufficient unit. By changing the parameters of connectivity (from permanent to temporary/removable) and autonomy (from grid-dependent to self-generating), the house achieves both relocatability and environmental compatibility
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 mobile house achieves zero ecological footprint by being self-sufficient in energy and water supply, with renewable energy systems and minimal environmental impact, enabling easy relocation without disrupting the site environment.
Implementation Method 1
The electric energy supply system is self-sufficient and employs renewable energy, in particular solar cells
Implementation Method 2
fresh air for ventilation is introduced into the house through a heat exchanger such that the exiting exhausted warmer air heats the introduced fresh but colder air
