Modular Home Rotation Pin Structure for Crane-Free Trailer Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current modular housing manufacturers face challenges in transporting modular homes to their final destination due to size restrictions and the need for cranes to lift and assemble modules, which are costly and labor-intensive.
Innovation Solution
A system and method involving a trailer that allows modular homes to be divided into portions, transported on a single trailer bed, and rotated and connected using robotic crawlers and winches, eliminating the need for cranes and manual labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If modular homes are transported as complete units, then transportation efficiency is improved, but size restrictions and road regulations prevent this approach
Solution Approach 1:
The modular home is divided into multiple segments that can be folded together. The housing structure includes foldable walls and partitions that allow the home to be collapsed into a compact configuration for transportation, then expanded at the destination to form the complete living space.
2Ease of manufacture
If cranes are used to lift and assemble modular modules, then assembly capability is improved, but cost and labor requirements increase significantly
Solution Approach 1:
The modular home includes self-contained assembly mechanisms such as spring-loaded expansion structures, telescoping walls, and automatic locking systems that enable the home to assemble itself without external cranes or heavy equipment. The structure transforms from a compact transport state to an expanded living state through automated or manual operation of integrated mechanisms.
3Length of moving object
If modular homes are divided into portions for transportation, then transportation feasibility is improved, but assembly complexity increases
Solution Approach 1:
Multiple modular segments are designed to fold together and interlock forming a unified structure. The segments include complementary joining mechanisms such as interlocking walls, integrated flooring systems, and combined roofing structures that merge the separate portions into a cohesive home without requiring complex assembly procedures.

Function Achieved in This Case
Enables efficient transportation and assembly of modular homes without cranes, adhering to size restrictions and reducing costs and labor requirements.
Implementation Method 1
a winch assembly coupled to a first lateral side of the bed and including a first winch and a boom. The first winch is configured to be connected to the first housing portion and to rotate the first housing portion about the first rotation pin
Implementation Method 2
extending a plurality of linear actuators coupled to overhanging portions of a modular structure positioned on a bed of a trailer until the linear actuators engage the ground and lift the modular structure off of the trailer
Implementation Method 3
the one or more crawlers to move the modular structure to an installation location

AI summary
A structure includes a first space defined by a plurality of walls and a floor assembly supporting the plurality of walls. The floor assembly includes a frame comprising a plurality of floor joists, at least one upper plate coupled to a top of the frame, and a skid plate coupled to a bottom of the frame, the skid plate comprising a circular opening. The floor assembly further includes a pin socket comprising a cylindrical pipe section positioned around the circular opening, the pin socket configured to receive a rotation pin within the cylindrical pipe section and configured to cause the rotation of the structure about the rotation pin when a lateral force is applied to the structure. The structure is configured to rest on the skid plate during the rotation.
