Trailer Torsion-Resistant Chamber Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trailers suffer from high torsion deflection and weight, limiting their ability to haul heavy payloads efficiently and maintaining structural integrity under torque and bending stress.
Innovation Solution
The design incorporates a substantially closed torsion-resistant chamber formed by an elongated shell connected to the floor, which includes interconnected plates or extrusions, strategically distributing mass away from the neutral axis and enhancing stiffness-to-weight ratio, thereby reducing torsion deflection and maintaining bending resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional trailer structure is used, then manufacturing simplicity is maintained, but torsion deflection increases and weight increases
Solution Approach 1:
The trailer structure is divided into modular components including the floor, elongated shell, and interconnected plates that form the torsion-resistant chamber. This segmentation allows for optimized weight distribution and targeted reinforcement where needed, reducing overall weight while maintaining torsion resistance.
Solution Approach 2:
The trailer employs composite construction combining the floor, elongated shell, and interconnected plates to create a torsion-resistant chamber. This composite structure achieves superior torsion resistance compared to conventional monolithic designs, providing strength without excessive weight.
2Stability of the object's composition
If conventional trailer structure is used, then manufacturing simplicity is maintained, but torsion deflection increases
Solution Approach 1:
The structure is segmented into the floor, elongated shell, and interconnected plates forming a modular torsion-resistant chamber. This segmentation enables controlled deformation characteristics and improved torsion resistance while keeping the overall design manageable.
Solution Approach 2:
The interconnected plates and elongated shell provide localized reinforcement at critical areas where torsion stress concentrates, such as near the front axle and at corner points. This local quality enhancement reduces torsion deflection without requiring complex reinforcement throughout the entire structure.
3Strength
If mass is distributed away from neutral axis, then torsion resistance improves, but structural complexity increases
Solution Approach 1:
The mass distribution is achieved through segmented construction with the elongated shell and interconnected plates positioned at specific locations. This segmentation allows strategic placement of material away from the neutral axis to maximize torsion resistance while maintaining manufacturing feasibility.
Solution Approach 2:
The design utilizes three-dimensional spatial arrangement of the elongated shell and interconnected plates to create a torsion-resistant chamber. By distributing mass in multiple dimensions rather than simply adding more material, the structure achieves superior torsion resistance with controlled complexity.

AI summary
Improved trailers (e.g., semi-trailers) are disclosed. The trailers may include a floor having a top surface and a bottom surface, where the top surface is adapted to transport a payload, and an elongated shell connected to the bottom surface of the floor, where the elongated shell defines a portion of a substantially closed torsion-resistant chamber of the trailer. The trailers may have a torsion resistance that is substantially higher than conventional trailers of similar size and/or load capacity. The trailers may weigh substantially less than conventional trailers of similar size and/or load capacity. The trailers may realize a bending resistance that is at least equivalent to the bending resistance of conventional trailers of similar size and/or load capacity.
