Movable Wall Extension for Side Dump Body Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Side dump trailers have limited carrying capacity due to their design, which restricts their height to avoid exceeding highway width restrictions, limiting their ability to increase capacity without compromising dumping functionality.
Innovation Solution
A wall extension apparatus is movably positioned on the upper ends of the side dump body, allowing it to pivot between a transport position and two dumping positions, using hydraulic cylinders or a pulley and cable system to increase carrying capacity without exceeding width restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the side walls of the side dump body are extended upward to increase carrying capacity, then the volume and load-carrying capacity are improved, but the side dump body would exceed highway width restrictions when in dumping position
Solution Approach 1:
The side walls are designed as movable rather than fixed structures. During transport, the side walls are positioned in a retracted configuration to comply with width restrictions. During dumping operations, the side walls can extend upward to increase carrying capacity. This dynamic reconfiguration allows the same structure to satisfy both contradictory requirements at different operational phases.
Solution Approach 2:
The side dump body is divided into a fixed base structure and movable side wall extensions. The side walls can be independently positioned relative to the base, allowing them to be raised for dumping while keeping the overall transport width within legal limits. This segmentation enables the structure to achieve both compact transport dimensions and expanded dumping capacity.
2Stability of the object's composition
If the side dump body is designed with fixed side walls to maintain structural stability, then the structural integrity is improved, but the ability to increase carrying capacity without exceeding width restrictions is worsened
Solution Approach 1:
The side walls are designed with controlled mobility rather than being completely fixed or completely free-moving. They can be positioned in stable configurations during both transport and dumping operations. The walls are supported by mechanisms that maintain structural integrity when extended, providing stability in both retracted and extended states while enabling increased carrying capacity when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The wall extension apparatus enhances the carrying capacity of side dump bodies by allowing them to pivot and dump contents from either side, maintaining compliance with highway width regulations while increasing load-carrying capacity.
Implementation Method 1
A forward hydraulic cylinder is secured to the forward end wall of the side dump body and to the forward end wall member of the wall extension apparatus and a rearward hydraulic cylinder is secured to the rearward end wall of the side dump body and to the rearward end wall member of the wall extension device for pivotally moving the wall extension apparatus
Implementation Method 2
a pulley and cable arrangement at the forward and rearward ends thereof
