Dump Body Removable Rear Component With Welded Wear Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dump bodies on machines like trucks experience excessive wear and tear and contact damage at the rear portion due to material sliding and contact with objects, compromising structural integrity and operational life.
Innovation Solution
A removable component for the dump body with a unified connection via welding surfaces across sidewalls and floors, providing a strong, robust attachment that minimizes wear and tear and facilitates easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If releasable fastening elements (bolts) are used to attach the replacement tail to the truck hopper, then the attachment can be easily assembled and disassembled, but the connection strength is insufficient and the attachment process is time consuming and complex
Solution Approach 1:
The patent replaces the mechanical fastening system (bolts and fastening elements) with a welding connection system. The removable component includes a welding surface that extends across the rear portion, allowing the component to be permanently attached to the base component of the dump body through welding, thereby achieving strong structural connection while maintaining replaceability.
2Reliability
If the rear portion of the dump body is made more durable to resist wear and tear, then the structural integrity is improved, but the cost and complexity of the dump body increases
Solution Approach 1:
The patent divides the dump body into two main segments: a base component and a removable component. The removable component is specifically designed to be replaceable and is positioned at the rear portion that experiences the most wear and tear. This segmentation allows the durable, wear-resistant removable component to be replaced independently without replacing the entire dump body, thereby maintaining structural integrity while managing complexity and cost.
Solution Approach 2:
The patent applies local quality by making only the rear portion (removable component) specially designed for wear resistance and replaceability, while the base component remains as the standard structure. The welding surface is specifically located at the rear portion where it is needed most, allowing enhanced durability exactly where wear and tear occurs without unnecessarily complicating the entire dump body structure.
3Strength
If the removable component is designed with a welding surface extending across sidewalls and floor, then the connection strength and structural integrity are improved, but the manufacturing complexity increases
Solution Approach 1:
The patent merges the welding surface across multiple surfaces (rear surface, sidewalls, and floor) of the removable component into a unified attachment system. This integration allows the welding to be performed across the entire interface between the removable component and base component, creating a strong, continuous structural connection that behaves as a single integrated piece while still maintaining the ability to replace the component as a unit.
