Segmented Bucket Edge Protection System for Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edge protection systems for earth working machines are inefficient in covering base edge gaps between tooth assemblies, requiring customization and potential misalignment, which can lead to increased wear and stress.
Innovation Solution
A universal edge protection system comprising interlocking edge protection segments of predetermined widths, which can be easily aligned and bonded to the bucket edge, covering gaps between tooth assemblies while maintaining clearance to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single large edge protector is used to cover the base edge, then the coverage area is increased, but the device complexity and difficulty of installation increase
Solution Approach 1:
The edge protector is divided into multiple segments that can be separately installed along the base edge of the bucket. Each segment covers a portion of the base edge, and together they provide comprehensive protection. This segmentation reduces the complexity of manufacturing and installing a single large protector while maintaining full coverage.
2Manufacturing precision
If custom-sized edge protectors are manufactured to fit specific gap sizes, then the precision of fit is improved, but the manufacturing cost and time increase
Solution Approach 1:
The edge protector segments are designed with standardized dimensions and features that allow them to be used across multiple bucket sizes and configurations. The universal design enables the same segment design to fit various base edge gaps through combination, eliminating the need for custom manufacturing for each specific application while maintaining precise fit.
3Reliability
If edge protectors are tightly fitted to the base edge, then the protection effectiveness is improved, but the stress concentration on the bucket edge increases
Solution Approach 1:
The edge protector segments are designed with varying thicknesses and profiles along their length, with thicker sections positioned where impact forces are greatest and thinner sections where less protection is needed. This local variation in quality provides effective protection at critical locations while reducing overall material usage and stress concentration on the bucket edge.

AI summary
An edge protection segment for an edge protection system of a ground engaging implement is disclosed. The edge protection segment includes a first side, a second side, a width, a wedge portion, an exterior leg, and an interior leg. The second side is oppositely disposed and lateral to the first side. The width is up to 6 centimeters and is the distance between the first side and the second side. The exterior leg and the interior leg each extend from the wedge portion. The wedge portion, the exterior leg and the interior leg each extend between the first side and the second side.
