Dump Body Corner Heating via Vertical Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dump body designs, particularly V-shaped and round bodies, face challenges in efficiently heating corners due to the placement of single linear ribs, leading to poor releasability of earth and sand, as the corners are not adequately heated by the exhaust gas flow path.
Innovation Solution
The implementation of a dump body design featuring a linear hollow lower rib with a flow-path forming section in a box shape that allows exhaust gas to bypass and directly heat corners, utilizing multiple openings and partitions to enhance heat distribution and retention, ensuring efficient heating of corners with a V-shaped or round body configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single linear rib is provided on the front plate, then productivity and production cost are improved and weight is reduced, but the corner heating efficiency deteriorates because the corner is spaced from the rib
Solution Approach 1:
The patent extends the heating function from a single linear horizontal dimension to a three-dimensional configuration by adding vertical ribs that extend downward from the horizontal rib. This creates a volumetric heating zone that can reach corners spaced below the rib level, solving the heating efficiency problem while maintaining the simplicity of the linear rib structure.
Solution Approach 2:
The rib structure is segmented into multiple functional components: a horizontal rib for general heating and vertical ribs for corner-specific heating. This segmentation allows each component to perform its specialized function efficiently while maintaining the overall simplicity and cost-effectiveness of the design.
2Temperature
If the rib is provided in a form conforming to the V-shape or round shape of the body, then corner heating efficiency is improved, but productivity and production cost deteriorate and weight increases
Solution Approach 1:
Instead of making the entire rib structure conform to complex V-shape or round shapes, the patent applies local quality by adding vertical ribs only at specific locations where corner heating is needed. The main horizontal rib remains simple and linear for easy manufacturing, while localized vertical extensions provide the necessary corner heating functionality.
3Reliability
If the inner curvature radius of the corner is increased, then releasability of earth and sand is improved, but a rib of irregular cross section is required which deteriorates productivity and production cost
Solution Approach 1:
The rib structure is segmented into simple horizontal and vertical components rather than requiring a single complex irregular cross-section rib. This segmentation maintains ease of manufacture while still achieving the necessary corner coverage for enhanced releasability when combined with increased curvature radius.
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
This design effectively enhances the releasability of earth and sand from corners by ensuring thorough heating, even in configurations where the corner is spaced from the single linear rib, improving productivity and reducing production costs while maintaining weight reduction benefits.
Implementation Method 1
exhaust gas from an engine is circulated in an exhaust gas flow path defined by an inner space of ribs provided in the body, thereby heating the body
Implementation Method 2
Heating the body vaporizes water contained in the earth and sand so that the earth and sand is dried
Implementation Method 3
the exhaust gas flow path comprises a flow-path forming section in a shape of a box that defines a bypass for an exhaust gas flowing in the exhaust gas flow path to go downward relative to the lower rib

AI summary
A dump body includes a front plate, a bottom plate integrally provided on a lower part of the front plate, and a pair of right and left side plates provided on sides of the front plate and the bottom plate. On a lower part of an outer surface of the front plate, a linear hollow lower rib extending in a right-left direction and a pair of right and left vertical ribs that are in communication with the lower rib at lower ends thereof are provided. An exhaust gas flow path of an exhaust gas is defined including an inner space of the lower rib and an inner space of the vertical ribs. The exhaust gas flow path is in communication a flow-path forming section of a box shape that allows the exhaust gas flowing in the exhaust gas flow path to go downward relative to the lower rib.
