Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building structures for rural areas with small spans are complex to assemble, require numerous materials, result in material waste, and are not reusable, leading to environmental pollution and long construction periods.
Innovation Solution
A modular building system using prefabricated reinforced concrete components, including a foundation block, wall panels, and vertical columns with specific engagement structures and protrusions/recesses for quick assembly, allowing for easy disassembly and reassembly, with cement poured into joints for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional brick wall or reinforced concrete structures are used, then the building has sufficient strength and stability, but the construction process becomes complicated and requires many auxiliary materials
Solution Approach 1:
The building is divided into standardized modular components including wall panels, floor panels, roof panels, and column assemblies that can be manufactured separately and assembled on-site. Each module is designed with standardized dimensions and connection interfaces, transforming the complex traditional construction process into a simplified assembly operation.
Solution Approach 2:
The modular components are pre-manufactured in factories with embedded reinforcement structures and connection elements already in place. The wall panels have pre-installed hanging posts, floor panels have pre-formed arc-shaped overlap grooves, and column assemblies have pre-attached protruding posts, eliminating the need for on-site construction of these elements.
2Stability of the object's composition
If traditional building materials are used, then the building structure is stable, but the materials cannot be reused and cause environmental pollution when removed
Solution Approach 1:
The modular building components are designed for disassembly and reuse. When the building reaches the end of its service life or needs relocation, the wall panels, floor panels, roof panels, and column assemblies can be systematically dismantled and reused for new construction projects, significantly reducing construction waste and environmental pollution.
Solution Approach 2:
The building transitions from a fixed permanent structure to a movable and reconfigurable system. The standardized connection interfaces allow the building to be disassembled, transported, and reassembled at different locations, providing dynamic adaptability while maintaining structural integrity throughout its lifecycle.
3Stability of the object's composition
If traditional building structures are used, then the building is stable, but it is fixed rather than movable
Solution Approach 1:
The building system transforms from a static fixed structure to a dynamic movable structure through standardized modular components with connection interfaces designed for easy assembly and disassembly. The wall panels, floor panels, roof panels, and column assemblies can be systematically disconnected and repositioned, enabling the building to adapt to different locations and usage requirements while maintaining structural stability.
4Reliability
If prefabricated reinforced concrete components are used for large-span buildings, then the structure is safe and reliable with quick assembly, but the structure becomes complicated for small-span rural buildings
Solution Approach 1:
The modular components are designed with different configurations suitable for specific structural positions and building types. Wall panels have hanging posts positioned according to their location (corner, edge, or middle), floor panels have arc-shaped overlap grooves arranged to match the building layout, and column assemblies have protruding posts configured for small-span rural building requirements, allowing simplified structures where appropriate.
Solution Approach 2:
The same basic modular components (wall panels, floor panels, roof panels, column assemblies) can be used for both large-span and small-span buildings by adjusting the arrangement and quantity rather than requiring fundamentally different structural systems. The standardized interfaces and modular nature allow the system to adapt to different building scales and types.

AI summary
The present invention discloses a modular building for civil use, which comprises a wall panel (6), a floor panel (5), a vertical column, and a foundation block (1).A protrusion (11) is provided at a center of a bottom surface of the foundation block (1), and a recess (12) is provided at a center of a top surface of the foundation block (1).A protruding post matched with the recess (12) of the foundation block (1) is provided at a bottom part of the vertical column. An engagement structure for connecting with the wall panel (6) and/or the floor panel (5) is provided on the vertical columns. The modular building for civil use is mainly applied to a civil building having a small span, and is an integrated transportable modular home made from reinforced concrete. Pre-made structural components for constructing the building, such as the wall panel (6), the floor panel (5), the vertical column, and the foundation block (1), are cast in a factory before being shipped to a building site. The structural components can befit together, and then cement can be poured into gaps at the joints thereof to complete construction. 90% of the construction work for the building can be completed in a factory, thereby enabling fast on-site assembly, rapid transport, and safe and reliable operation.
