Angled Trailer Frame for Portable Structure Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trailers are inefficient for transporting portable toilet structures due to high wind resistance and lack of standardized elements for quick and secure loading/unloading, especially on conventional flat bed trailers.
Innovation Solution
A trailer design with a central axle, angled base frame, and securing rods that positions the portable structure at a 45-degree angle, reducing wind resistance and enhancing stability by deflecting wind laterally and accommodating the diagonal dimension of the structure, with a wider axle for increased stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If portable toilet structures are transported on conventional flat bed trailers, then they can be moved between locations, but wind resistance is high and stability is reduced due to the shape of the structures and wind resistance exerted against the housing walls
Solution Approach 1:
The trailer positions the portable toilet structure at a 45-degree angle rather than parallel to the direction of travel, creating an asymmetric orientation that reduces the effective wind surface area and allows wind to deflect laterally around the structure, thereby reducing wind resistance and improving stability
Solution Approach 2:
The invention introduces a angular dimension (45-degree angle) to the positioning of the portable toilet structure on the trailer, transforming the traditional linear alignment with the direction of travel into an angled configuration that exploits lateral wind deflection to reduce aerodynamic resistance
2Ease of operation
If conventional flat bed trailers are used, then portable structures can be transported, but there is no standardized element for quickly and easily securing the portable toilet structure to the trailer
Solution Approach 1:
The trailer is pre-equipped with standardized securing elements (chains, hooks, or rods) positioned at predetermined locations on the angled base frame, allowing for quick attachment to the portable toilet structure without requiring complex assembly or adjustment during loading and unloading operations
Solution Approach 2:
The standardized securing elements are designed to work with multiple types of portable toilet structures, providing a universal attachment system that can quickly secure different structures without requiring custom fabrication or complex adaptation
3Object-affected harmful factors
If the portable toilet structure is positioned at a 45-degree angle on the trailer, then wind resistance is reduced and stability is improved, but the trailer requires a wider axle and angled base frame design
Solution Approach 1:
The trailer design segments the base frame into angled support members that form the 45-degree configuration, allowing the complex angled structure to be constructed from simpler modular components rather than requiring a monolithic complex frame

Function Achieved in This Case
The trailer design reduces wind resistance and improves stability during towing, ensuring smoother operation and increased safety for occupants and other road users by naturally deflecting wind and maintaining structural integrity at highway speeds.

AI summary
A trailer for use primarily for transporting a portable structure in which a frame is mounted on an undercarriage with the wheels of the undercarriage near the longitudinal center and the portable structure is positioned at an angle to reduce wind resistance while the structure is being transported on the trailer. The portable structure is secured to the trailer by placing the skid plates of the portable structure under frame elements affixed to the trailer frame.
