Split Side Plate Structure for Replaceable Earth-Removal Wear Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounted earth removal devices have side plates that are prone to high wear due to contact with the ground, requiring replacement of the entire side plate, which is cumbersome and inefficient.
Innovation Solution
The side plates are designed in a multipart fashion, comprising a lift component and a swivel component, allowing the ground contact section to be replaced independently, while the other components remain on the device housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the side plate is designed as a one-piece structure, then the structural strength and simplicity are improved, but the maintenance difficulty and replacement effort increase due to high wear on the ground contact section
Solution Approach 1:
The side plate is divided into multiple components: a lift component, a swivel component, and a ground contact section. This segmentation allows the ground contact section to be replaced independently when worn, without replacing the entire side plate assembly, thereby reducing maintenance effort and cost while maintaining the structural integrity of the non-wearing parts.
2Device complexity
If the ground contact section is integrated with the lift component, then the structural simplicity is improved, but the replacement time and effort increase when the ground contact section wears out
Solution Approach 1:
The side plate assembly is segmented into a lift component and a separate ground contact section. The ground contact section can be detached and replaced independently, significantly reducing replacement time and effort compared to replacing an integrated one-piece structure, while the segmentation is designed to maintain overall structural simplicity.
3Ease of manufacture
If the side plate is designed as a single component, then the manufacturing process is simplified, but the device lifespan is reduced due to inability to replace only worn parts
Solution Approach 1:
The side plate is designed as a multipart assembly with a lift component and a replaceable ground contact section. This allows the ground contact section to be replaced when worn, extending the overall lifespan of the side plate assembly without significantly complicating the manufacturing process, as each component can be manufactured separately and assembled.
