Dozer Controller for Uniform Pile Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dozer machines often form piles of varying sizes due to factors like depressions on the work surface and material shedding, leading to uneven surfaces when compacted.
Innovation Solution
A method and system where a controller determines the volume of material transported by the machine and adjusts parameters such as pile height and area based on comparisons with a threshold volume, ensuring equal-sized piles are formed and deposited at regular intervals.

Engineering Contradiction Analysis
1Productivity
If a dozer machine pushes material to form piles, then material is moved and piles are formed, but the piles vary in size leading to uneven surfaces
Solution Approach 1:
The system performs preliminary measurement of the actual material volume before pile formation, then uses this information to adjust deposition parameters in advance to achieve uniform pile sizes
Solution Approach 2:
The system implements a feedback loop where sensors measure actual material volume, the controller compares it with target values, and adjusts deposition parameters based on the deviation to maintain consistent pile sizes
2Manufacturing precision
If the machine deposits material to form piles, then piles are created on the worksite, but the time and effort required to achieve equal-sized piles increases
Solution Approach 1:
The system enables the machine to automatically measure, calculate, and adjust its own deposition parameters without operator intervention, making the system self-regulating for consistent pile formation
Solution Approach 2:
The patent replaces manual operator judgment and mechanical adjustment with an automated electronic control system that uses sensors and algorithms to determine optimal deposition parameters

AI summary
A method for depositing a pile of material by a machine at a worksite. The method includes determining, by a controller, a volume of material transported by the machine. The method further includes determining, by the controller, at least one parameter associated with the pile to be formed by the determined volume based on a comparison of the determined volume with a threshold volume and operating the machine to deposit the determined volume to form the pile, on a working surface of the worksite, based on the at least one parameter.
