Prefabricated Container House with Expandable Dwelling Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prefabricated houses are cumbersome to move and extend, as they require extensive assembly and are limited by their fixed size, making it difficult to increase living space efficiently.
Innovation Solution
A prefabricated container house design that includes a transportable main frame member and housed dwelling forming members, which can be easily assembled and expanded at the installation site, allowing for minimal assembly work and nearly tripled living space through modular expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a prefabricated house is assembled at a construction site with housing frame members and partitioning members, then the house can be built as a dwelling, but it takes time to disassemble and cannot be moved easily
Solution Approach 1:
The house is divided into a main body (transportable unit) and house forming body (dwelling structure). The main body contains all necessary components (floor members, roof members, wall members) that can be segmented and reassembled at different locations, enabling both easy assembly and movability
Solution Approach 2:
The house forming body members are housed inside the main body during transport, similar to nested dolls. At the construction site, these members are drawn out and assembled to form the dwelling. This nesting approach allows the house to be compact for transport yet expandable for assembly, resolving the contradiction between movability and ease of assembly
2Adaptability or versatility
If a trailer house is assembled into a complete house structure, then it can be moved to any installation site, but the size is limited and cannot be extended
Solution Approach 1:
The house forming body is segmented into multiple detachable members (floor members, roof members, wall members) that can be independently stored and assembled. This segmentation allows the house to be extended by adding more members without limiting the base movability of the main body
Solution Approach 2:
The house structure allows for extension in multiple dimensions. The main body can be extended by drawing out house forming body members to increase living space horizontally, and multiple main bodies can be stacked vertically to create multi-story dwellings. This dimensional flexibility resolves the contradiction between movability and extensibility
3Stability of the object's composition
If a prefabricated house is fastened at the construction site, then it provides structural stability, but it cannot be moved and extension work is cumbersome
Solution Approach 1:
The connection between the main body and house forming body is designed to be dynamic rather than fixed. The house forming body members can be drawn out from and retracted into the main body, allowing the structure to transition between a stable assembled state and a movable disassembled state. This dynamic design resolves the contradiction between structural stability and movability

AI summary
A prefabricated container house includes a container type main frame member when on a chassis capable of being pulled by a trailer truck; and dwelling forming members which can be housed in the main frame member, and which can be drawn out of the main frame member at an installation site, and assembled into a house.
