Wheel Loader Bucket With Sloped Side Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bucket designs for wheel loaders lack productivity and cost-effectiveness, with limited manufacturing efficiency and smooth material handling.
Innovation Solution
A bucket configuration featuring a center section and sloped lateral side sections that increase filling volume, facilitate smooth material flow, and maintain standard dimensions for tipping, while simplifying manufacturing and attachment to wheel loaders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the bucket filling volume is increased, then productivity is improved, but the standard dimensions for tipping may be compromised
Solution Approach 1:
The patent introduces sloped lateral side sections that extend in both the width direction and rearward direction, creating bucket pockets that utilize three-dimensional space. This dimensional expansion allows increased filling volume without proportionally increasing the longitudinal dimensions required for tipping, as the additional capacity is achieved through lateral and rearward extension rather than forward extension.
2Ease of operation
If the bucket shape is made smoother for easier material handling, then ease of operation is improved, but manufacturing complexity may increase
Solution Approach 1:
The floor section is divided into distinct segments: a center section and lateral side sections with sloped profiles. This segmentation allows each section to be optimized independently - the center section provides structural stability while the sloped lateral sections create smooth material flow paths. The segmented design simplifies manufacturing compared to a monolithic complex curved shape, as each segment can be formed using standard fabrication processes.
3Productivity
If the bucket is designed for faster filling, then productivity is improved, but the depth of crouching into heap may be reduced
Solution Approach 1:
The sloped lateral side sections create bucket pockets that extend rearward from the center section, utilizing the rearward dimension to increase filling capacity. This allows the bucket to achieve greater filling volume without increasing the longitudinal depth of crouching into the material heap, as the additional capacity is achieved through lateral and rearward expansion rather than deeper forward crouching.
