Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction methods for multi-story and high-rise buildings face challenges with modular construction, including weight and transportation issues, high costs, and inefficiencies in on-site assembly, making it difficult to adapt manufactured housing techniques for such structures.
Innovation Solution
A construction system utilizing premanufactured, preassembled, and prefinished components, including non-weight bearing walls, interior, and exterior components, which are assembled in a factory and quickly installed on-site to create energy-efficient, multi-story buildings with standardized components, reducing material waste and labor costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manufactured housing modules are used for multi-story buildings, then construction speed and quality control improve, but weight and transportation costs increase significantly
Solution Approach 1:
The building is divided into multiple premanufactured modules that can be constructed separately in factories and then assembled on-site. Each module contains complete functional units (walls, floors, ceilings, utilities) that are transported and stacked to form multi-story buildings, resolving the contradiction by enabling rapid construction through modular assembly while managing weight through standardized sizing and distribution.
Solution Approach 2:
The invention transitions from traditional horizontal transportation of modules to vertical stacking and assembly. Modules are designed to be stacked vertically to create multi-story buildings, utilizing the vertical dimension to reduce the number of modules needed per building and thereby reducing overall transportation requirements and costs.
2Weight of moving object
If conventional on-site construction methods are used for high-rise buildings, then weight and transportation issues are avoided, but construction time and labor costs increase
Solution Approach 1:
Building modules are premanufactured in factories before site assembly, with all structural components, utilities, and finishes prepared in advance. This preliminary fabrication of complete modules in controlled factory environments enables rapid on-site assembly, dramatically reducing construction time compared to traditional sequential on-site building methods.
Solution Approach 2:
Multiple modules are manufactured simultaneously in factory assembly lines while site preparation occurs concurrently. The continuous production process in factories, combined with parallel site preparation and sequential module assembly, maintains continuous useful action throughout the construction process, maximizing productivity and minimizing total construction time.
3Manufacturing precision
If modules are manufactured at a distant factory, then construction quality and environmental control improve, but transportation costs and handling complexity increase
Solution Approach 1:
Modules are designed with standardized connection interfaces and attachment mechanisms specifically optimized for their intended locations in the building structure. Each module type (corner, interior, exterior wall modules) has customized features for its specific position, simplifying handling and assembly operations while maintaining high manufacturing precision through specialized factory production for each module category.

AI summary
Premanufactured structures for constructing buildings comprise a construction system for an energy efficient multi-story building with standard single or mixed units. The multi-story building is constructed using premanufactured structures: non-weight bearing walls with finished exterior including all electrical, insulating, plumbing and communications components that are premanufactured at a site distant from a building site, and the non-weight bearings walls are attached to a floor and ceiling slabs, interfacing with each other to enclose units of the building; interior components that are premanufactured at a remote site to connect to inside portions of the non-weight bearing walls; and exterior components that are premanufactured at the remote site to attach to exterior surfaces of the building. Non-weight bearing walls, interior components, and exterior components are installed and connected together to provide the energy efficient multi-story building with units with different floor plans, and optionally, a retail level with underground parking.
