Modular Building Fabrication Using Container-Based Preassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction industry faces challenges such as cost overruns, labor shortages, inadequate communication, disorganized document management, and inefficient planning, leading to delays and increased project risks.
Innovation Solution
A method for rapid fabrication of modular building components using standardized shipping containers, which involves framing, installation of plumbing and electrical systems, and assembly in a controlled environment, followed by on-site integration with a foundation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional on-site construction methods are used, then workers can assemble structures directly at the project location, but construction time increases and productivity decreases
Solution Approach 1:
The building is divided into modular components that can be pre-assembled in factories and then transported to the construction site for rapid assembly, resolving the contradiction by separating the manufacturing and assembly processes spatially and temporally
Solution Approach 2:
Modular building components are pre-fabricated in controlled factory environments before being transported to the construction site, allowing simultaneous preparation of multiple components and reducing on-site construction time
2Productivity
If modular construction methods are adopted, then construction time is reduced and productivity increases, but initial setup and planning complexity increases
Solution Approach 1:
Standardized modular components are designed to serve multiple functions and be used in various building configurations, reducing the variety of unique parts needed and simplifying the overall system while maintaining high productivity
3Loss of substance
If traditional construction methods are used, then material delivery can be done on-site, but material waste increases and environmental impact worsens
Solution Approach 1:
Building modules are pre-fabricated in controlled factory environments where materials can be precisely measured, cut, and assembled with minimal waste, and excess materials can be recovered and reused, significantly reducing material waste and environmental impact compared to traditional on-site construction
4Reliability
If on-site construction is performed, then all materials can be delivered directly to the project location, but weather-related delays increase and reliability decreases
Solution Approach 1:
The construction process is segmented into factory-based module fabrication and on-site assembly, allowing the majority of construction activities to occur in controlled factory environments that are immune to weather conditions, thereby improving project completion reliability
Solution Approach 2:
Building modules are pre-fabricated in controlled factory environments before being transported to the construction site, protecting the construction process from weather-related delays and improving project reliability

AI summary
A method for the construction of a habitable structure. The method including the receiving of a module consisting of four walls, a ceiling, and a floor. Next the method requires the reviewing of a set of shop drawings to determine the required modifications to the module to fabricate at least one bathroom and a kitchen within the interior of the module. The method requires installing framing, plumbing and electrical consistent with the shop drawings and then transferring the module to a job site where it is attached to a pad or a foundation. Next the method requires the constructing of additional living space around the footprint of the module and within the perimeter of the at least one of the pad or the foundation.
