Prefabricated Room Units with Cellular Board for Self-Supporting Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for constructing multi-storey rooms and ship cabins require heavy, space-consuming load-bearing structures that conduct heat and sound, and fail to effectively connect prefabricated units for self-supporting, insulated solutions.
Innovation Solution
The use of prefabricated room units with cellular board structures for walls, floors, and ceilings that are connected via a connecting profile, eliminating the need for separate load-bearing structures and allowing units to support each other, thereby forming a self-bearing, insulated, and fire-safe arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional load-bearing structures (steel decks, floor structures) are used to support prefabricated room units, then the structural strength and stability are sufficient, but the weight and space consumption increase significantly
Solution Approach 1:
The patent merges the load-bearing function with the room units themselves. The prefabricated room units are designed to carry each other vertically without requiring separate load-bearing decks or floor structures. This integration eliminates the need for heavy steel support structures while maintaining structural integrity, directly resolving the contradiction between structural strength and weight reduction.
Solution Approach 2:
The patent extracts the load-bearing function from traditional separate structures (decks, floor structures) and transfers it to the room units themselves. By removing the need for continuous load-bearing bases and allowing room units to support each other directly, the heavy steel support structures are eliminated, achieving significant weight reduction while preserving structural strength.
2Stability of the object's composition
If traditional load-bearing structures are used, then structural stability is ensured, but the construction time and cost increase
Solution Approach 1:
The load-bearing connections between room units are designed to be pre-fabricated and integrated into the room units before installation. This preliminary preparation allows for rapid assembly on-site without requiring time-consuming installation of separate load-bearing structures, thereby maintaining structural stability while reducing construction time.
Solution Approach 2:
By combining the load-bearing function with the room units themselves, the patent eliminates the need for separate installation phases for support structures. The room units are designed to be self-supporting, allowing direct vertical stacking and connection, which streamlines the construction process and reduces overall construction time while ensuring structural stability.
3Strength
If continuous load-bearing bases are used, then structural support is provided, but heat and sound conduction increase
Solution Approach 1:
The patent segments the continuous load-bearing base into discrete connection points between individual room units. This segmentation interrupts the continuous path for heat and sound conduction that exists in traditional steel deck structures. The load-bearing function is maintained through localized connections, while the harmful thermal and acoustic conduction is reduced by breaking the continuous metallic path.
Solution Approach 2:
The patent introduces intermediary elements at the connection points between room units that provide load-bearing support while reducing thermal and acoustic conduction. These intermediaries act as mediators that transfer mechanical loads while minimizing the transmission of heat and sound, thereby resolving the contradiction between structural support and harmful conduction.
4Strength
If separate load-bearing structures are used, then structural function is fulfilled, but the device complexity increases
Solution Approach 1:
The patent merges the load-bearing structure with the room units themselves, eliminating the need for separate support systems. The room units are designed to carry each other vertically through integrated connection mechanisms, reducing the overall number of structural components and simplifying the structural system while maintaining full load-bearing functionality.
Solution Approach 2:
The patent extracts the load-bearing function from separate structural systems and transfers it to the room units. By removing the need for independent load-bearing decks, floor structures, and support columns, the structural system is simplified to consist only of the essential connection elements between room units, significantly reducing device complexity.

AI summary
Room arrangements include at least two superposed prefabricated load-bearing room units. The room units have a ceiling, a floor and at least two walls that are made at least mainly of cellular board. Ships, buildings and methods for constructing a room arrangement are also provided, especially the construction of multi-storey rooms, for example, cabin compartments in ships or block of flats without middle decks or intermediate floors.
