The method involves manufacturing prefabricated three-dimensional modules on robotic conveyors with formwork systems that allow for high-precision dimensions and rapid changes in size and shape, enabling floor-by-floor installation and connection of modules using robotic conveyors and lifting devices, which simplifies the construction process and enhances building stability and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional three-dimensional blocks are used for construction, then the construction process is simple, but the productivity is low and the space-planning flexibility is limited
Solution Approach 1:
The building is divided into standardized three-dimensional modules that can be manufactured separately and assembled systematically. Each module is a complete functional unit with standardized dimensions and connection interfaces, enabling parallel production and rapid assembly, thereby significantly improving construction productivity while maintaining configuration flexibility through modular组合
Solution Approach 2:
The module system incorporates adjustable and reconfigurable elements that allow the building configuration to be modified after construction. The standardized connection interfaces enable modules to be repositioned, added, or removed according to changing space-planning requirements, providing dynamic adaptability without compromising construction efficiency
2Manufacturing precision
If modular frames are used with complete factory finishing, then the quality and comfort of premises improve, but the mass of module structure per square meter increases and productivity decreases
Solution Approach 1:
Different levels of finishing and equipment installation are applied to different modules based on their specific functional requirements. Critical areas receive complete factory finishing while other areas use standardized base finishes, optimizing the balance between quality and productivity by avoiding unnecessary finishing work that would increase mass and production time
Solution Approach 2:
Essential structural elements and connection interfaces are prepared in advance during module manufacturing, while non-critical finishing work is designed for post-assembly completion. This preliminary preparation ensures high-quality structural assembly and rigidity without requiring all finishing operations to be performed in the factory, thereby maintaining construction productivity
3Ease of manufacture
If the same type of blocks are manufactured, then the manufacturing process is simplified, but the ability to change configuration and planning solutions is limited
Solution Approach 1:
A universal standardized module is designed with configurable internal layouts and adaptable connection interfaces. The module maintains standardized external dimensions and connection points for manufacturing simplicity, while incorporating adjustable internal partitions, movable walls, and reconfigurable services that enable diverse configuration and planning solutions according to different functional requirements
Solution Approach 2:
The module design incorporates nested or layered configurability where standardized structural elements contain adjustable internal components. The fixed external shell provides manufacturing simplicity while the nested internal elements can be reconfigured to create different spatial arrangements and functional layouts, achieving both manufacturing ease and configuration versatility
4Stability of the object's composition
If floor-by-floor re-laying of modules is performed, then the building rigidity and stability increase, but the construction time and labor costs increase
Solution Approach 1:
The floor-by-floor assembly process is segmented into parallel work streams where multiple modules on the same floor can be installed simultaneously using multiple lifting devices. The standardized connection interfaces enable independent installation of each module without sequential dependencies, maintaining structural stability requirements while reducing overall construction time through parallelization of assembly operations

AI summary
The invention relates to the field of construction. A method for constructing buildings consists in that prefabricated three-dimensional modules are manufactured on robotic conveyors arranged on a plant floor. A formwork system is formed on a first robotic conveyor and a three-dimensional monolithic reinforced-concrete module comprising a base plate and/or pillars and/or walls and/or beams and/or crosspieces and/or ceiling panels is manufactured in said formwork system. The manufactured module is transferred to a second robotic conveyor where structural components, utility lines and fitted furniture are installed on said module, interior and/or exterior finishing work is carried out and said module is packaged in a protective material. The prefabricated three-dimensional modules are transferred to a building site where they are installed in the desired location by means of lifting devices, are unpacked and the modules are assembled and connected to one another floor-by-floor, resulting in the formation of a building. A portion of the prefabricated three-dimensional modules of even-numbered floors are installed relative to a portion of the prefabricated three-dimensional modules of odd-numbered floors so that, in plan view, some of the walls thereof intersect.
