Solution Overview

Problem

Existing buckets for earth moving machines, such as scrapers, face challenges in varying capacity without increasing weight or limiting movement, especially in narrow spaces, and existing solutions like rock guards do not effectively enhance capacity while maintaining operational flexibility.

Innovation Solution

A bucket design with a variable capacity achieved through an extension plate that slides within the bucket's volume, allowing the capacity to increase without altering the bucket's width, using guide means and cut-out portions to ensure smooth operation and unobstructed movement, and allowing for customization and cost-effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the bucket capacity is increased to handle greater quantities of material, then the productivity is improved, but the weight of the bucket increases making it more difficult to control

Engineering Contradiction:
Improvematerial handling capacityVSAvoidbucket weight
Core Design Contradiction:
ProductivityVSWeight of moving object

Solution Approach 1:

The bucket incorporates a movable extension plate that can be positioned in different locations along the bucket walls, allowing the bucket capacity to be dynamically adjusted. This enables the operator to increase capacity when needed while maintaining a smaller, more manageable size for routine operations, thus resolving the contradiction between handling large quantities and maintaining control.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bucket is divided into a fixed base structure and a separate movable extension plate. This segmentation allows the extension plate to be independently positioned or removed, enabling flexible capacity adjustment without permanently increasing the bucket's base weight or compromising control during normal operations.

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If the bucket width is increased to expand capacity, then the volume is improved, but the bucket becomes unsuitable for narrow space operations

Engineering Contradiction:
Improvebucket capacityVSAvoidbucket width
Core Design Contradiction:
Volume of moving objectVSLength of moving object

Solution Approach 1:

Instead of permanently increasing the bucket width, the extension plate can be moved to different positions along the length of the bucket, dynamically expanding capacity only when needed. When the plate is retracted to its initial position, the bucket maintains its original narrow width profile, allowing it to operate in confined spaces.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The extension plate utilizes the longitudinal dimension of the bucket (along its length) rather than expanding the transverse width. By sliding the plate along the bucket walls in the longitudinal direction, capacity is increased without increasing the bucket's width, thus maintaining suitability for narrow space operations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Volume of moving object

If rock guards or spill guards are attached to increase capacity, then the volume is improved, but the movement of the bucket is limited

Engineering Contradiction:
Improvebucket capacityVSAvoidbucket movement freedom
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The extension plate is designed to be movable rather than fixed, allowing it to be positioned optimally for different operations. When not in use, it can be retracted to its initial position where it does not interfere with bucket rotation or movement, maintaining full operational freedom while still providing capacity expansion capability when needed.

Inventive Principle:
Principle #15Dynamics
