Side Dump Trailer Body Stiffening Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional side dump trailers experience undesirable flexing during use, leading to structural cracks due to insufficient stiffening, despite the use of side stiffening rails.
Innovation Solution
A multi-layered stiffening structure comprising front, intermediate, and rear body stiffening structures, along with elongated rail members, is secured to the exterior surfaces of the side dump body, utilizing angle members and rib assemblies to enhance rigidity and prevent twisting or bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If side stiffening rails are secured to the upper ends of the side walls, then flexing of the side dump body is reduced, but structural cracks still occur due to insufficient stiffening
Solution Approach 1:
The stiffening structure is divided into multiple segments: upper stiffening rails at the top, intermediate stiffening angles in the middle section, and lower stiffening angles near the bottom. This segmentation allows each component to address flexing in specific zones, providing comprehensive reinforcement throughout the side dump body and preventing structural cracks more effectively than a single continuous rail.
Solution Approach 2:
The invention transitions from one-dimensional stiffening (single horizontal rail) to two-dimensional reinforcement by adding vertical spacing between upper and lower stiffening elements. This creates a distributed stiffening system that resists flexing forces from multiple directions and prevents crack propagation through the entire height of the side wall.
2Reliability
If additional stiffening structures are added to reduce flexing, then structural integrity is improved, but device complexity increases
Solution Approach 1:
Different stiffening components are strategically placed at specific locations: upper stiffening rails are positioned at the top where flexing occurs during dumping, intermediate angles are placed in the middle section, and lower angles are positioned near the bottom. Each component's shape and position are optimized for its specific location, providing effective reinforcement without unnecessarily complicating the overall structure.

AI summary
The side dump trailer including a side dump body pivotally mounted on a wheeled frame and which is pivotally moveable between a transport position to at least one side dumping position. A body stiffening structure assembly is secured to the exterior surface of the side dump body and is comprised of two or more body stiffening structures welded to the exterior surface of the side dump body in a spaced-apart relationship. The body stiffening structures include elongated stiffening rails secured thereto and extending therebetween which are also welded to the side walls of the side dump body.
