Modular Building Assembly with Integrated Reinforcing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular container systems for temporary buildings, such as schools, face issues with manufacturing errors leading to poor finishes, reduced structural safety, and low reuse rates due to on-site assembly and the need for additional finishing work, which compromises the quality and earthquake resistance of the structures.
Innovation Solution
A method for constructing relocatable buildings using modules where 100% complete modules are manufactured in a factory, including internal and external finishing, and assembled on-site with integrated frame structures reinforced from foundation to roof using coupling pieces and reinforcing means, ensuring airtightness and improved structural safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If modules are assembled on-site with final finishing materials installed, then ease of construction is improved, but manufacturing precision deteriorates due to manufacturing errors accumulating in joined parts
Solution Approach 1:
The patent applies preliminary action by pre-assembling modules in a factory setting with controlled conditions before transport to the construction site. The modules are manufactured with precise finishing work completed in advance, eliminating on-site finishing operations. This preliminary factory assembly ensures high manufacturing precision while maintaining construction efficiency through standardized modular units.
2Productivity
If container modules are used for temporary buildings, then productivity is improved through fast assembly, but reliability deteriorates due to reduced structural safety and earthquake resistance
Solution Approach 1:
The patent employs composite materials by integrating steel frame structures with concrete infill panels in the modular construction system. This composite approach combines the high strength and ductility of steel with the compressive strength and rigidity of concrete, creating modules that achieve both rapid assembly through standardization and enhanced structural safety through material synergism, thereby improving earthquake resistance while maintaining productivity.
3Ease of operation
If modules are designed for easy transportation and lifting, then ease of operation is improved, but weight is reduced which compromises structural integrity
Solution Approach 1:
The patent applies segmentation by dividing the building into standardized modular units that can be independently manufactured, transported, and assembled. Each module is designed as a complete functional unit with integrated frame and finishing, allowing optimized weight distribution and standardized lifting points. This segmentation enables easy transportation and handling while maintaining structural integrity through the standardized design and connection systems.

AI summary
Proposed is a method for constructing a relocatable building by using modules, the method including a step a) of preparing a single module and installing a foundation block at a site, a step b) of forming a complex module having one room by assembling at least two single modules with each other on an assembly table near the site, a step c) of lifting the assembled complex module and installing the complex module on the foundation block, and a step d) of installing a roof module on an uppermost complex module and integrally reinforcing the foundation block, the complex module, and the roof module by using a reinforcing means.
