Foldable Transportable Buildings with Fork Tube Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction methods, such as 'stick-built' techniques, are inefficient and costly, as they require on-site assembly of raw materials, leading to increased labor and time costs, and there is a need for innovative solutions to reduce these expenses while maintaining structural integrity and ease of transportation.
Innovation Solution
A folded building structure comprising a multi-layered laminate design with a foam panel layer sandwiched between structural layers, featuring edge reinforcements and fork tubes for load transfer and assembly, allowing for compact shipping and easy assembly on-site, adhering to transportation dimensions without the need for oversized permits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If stick-built construction methods are used, then structural integrity can be achieved, but labor costs and construction time increase significantly
Solution Approach 1:
The building structure is divided into modular panels that are pre-assembled in factories and then transported to the construction site. Each panel is a self-contained unit with standardized dimensions and integrated components, allowing rapid on-site assembly without complex field construction activities.
Solution Approach 2:
All manufacturing activities including cutting, assembling, and finishing are performed in advance at factory locations. Panels are produced with precise tolerances and quality control before shipping, eliminating the need for time-consuming on-site fabrication and reducing construction duration.
2Loss of time
If factory-fabricated modular panels are used, then construction time and labor costs are reduced, but transportation dimensions and shipping costs increase
Solution Approach 1:
The panel design incorporates nested or overlapping configurations that allow large surface area panels to be compacted into smaller transportable units. Panels can be folded, telescoped, or arranged in nested patterns that reduce their effective dimensions during shipping while maintaining full size when deployed.
Solution Approach 2:
The panel structure utilizes three-dimensional geometry and spatial arrangement to maximize the amount of building material that can be transported within standard shipping container dimensions. By optimizing the panel's thickness, folding patterns, and stacking arrangements, the design fits large-area panels into conventional transportation constraints.
3Productivity
If modular panel design is implemented, then assembly speed increases, but structural strength and load-bearing capacity may be compromised
Solution Approach 1:
The panels utilize composite material construction combining wood products, metal fasteners, and engineered materials to achieve high strength-to-weight ratios. The multi-layer composite structure provides both the rigidity needed for load-bearing applications and the modularity required for rapid assembly.
Solution Approach 2:
The panel design incorporates curved or arched structural elements that distribute loads more effectively across the panel surface. These geometric features enhance the load-bearing capacity of the modular panels while maintaining their ability to be quickly assembled using standardized connection systems.
