Trailer Chassis Table Compartment With Welded Beam Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailer chassis assemblies for under-chassis storage are difficult to install and expensive, limiting the storage of folding tables in recreational vehicles and towed trailers.
Innovation Solution
A storage compartment is mounted to the frame beams of a trailer chassis using C-shaped beams welded between I-beams, providing accessible storage for folding tables with a removable cover for protection, and allowing easy installation and cost-effective integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing under-chassis storage bins are used, then storage space is provided, but installation becomes difficult and cost increases
Solution Approach 1:
The storage compartment is divided into modular components: C-shaped beams that attach to frame beams, cross members that provide structural support and access, and a removable cover. This segmentation allows for easier installation and assembly compared to monolithic storage solutions, directly addressing the contradiction between ease of manufacture and storage functionality.
Solution Approach 2:
The storage compartment structure serves multiple functions: the C-shaped beams provide structural attachment, the cross members enable access and additional support, and the assembly can accommodate various stored items including folding tables. This multi-functionality maintains storage effectiveness while simplifying the overall design and installation process.
2Ease of operation
If storage space is added for folding tables, then carrying burden is reduced, but storage space becomes even more limited
Solution Approach 1:
The storage compartment utilizes the vertical dimension by positioning it between the head and foot of the I-beams, effectively using under-chassis space that would otherwise be unused. This dimensional approach provides accessible storage for folding tables without significantly increasing the horizontal footprint, thus maintaining ease of operation while preserving available storage volume.
3Strength
If C-shaped beams are welded between frame beams, then structural strength is improved, but manufacturing complexity increases
Solution Approach 1:
The attachment structure is segmented into discrete C-shaped beams that can be independently fabricated and then welded to the frame beams. This segmentation allows for simplified manufacturing of individual components while achieving strong structural attachment, resolving the contradiction between strength and manufacturing complexity.

AI summary
A trailer chassis includes a first frame beam, a second frame beam parallel to and spaced from the first frame beam, and a plurality of cross members connected between the first frame beam and the second frame beam. A storage compartment for a folding table or the like is cooperable with the first and second frame beams.
