Material Layering Control for Premature Direction Reversal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Material moving machines, such as dozers, often experience inefficient and uneven layer creation during material relocation, leading to unsteady movement and inefficiencies in operations like mining, where layers are stacked on top of each other.
Innovation Solution
A computer-implemented method and control system that monitors the location of the material moving machine, identifies premature direction reversals, and instructs the machine to reposition improperly placed material piles to their target locations, ensuring accurate stacking and efficient material movement by using sensors and algorithms to adjust the machine's path and blade operations.

Engineering Contradiction Analysis
1Productivity
If the material moving machine operates autonomously to maintain consistent productivity, then productivity is improved, but the precision of material pile placement deteriorates due to premature direction reversals
Solution Approach 1:
The control system continuously monitors the machine's location and compares it against the work plan to detect premature direction reversals. This feedback mechanism allows the system to identify placement errors and trigger corrective actions, maintaining both productivity and precision in autonomous operation.
Solution Approach 2:
The system automatically detects and corrects premature direction reversals without human intervention. The control system identifies the error, calculates the correction, and executes the remedy autonomously, allowing the machine to self-correct while maintaining consistent productivity.
2Productivity
If the machine moves material as stacked layers to expose material for mining, then the mining operation efficiency is improved, but the layer uniformity deteriorates resulting in unsteady movement
Solution Approach 1:
The control system monitors material pile placement against the work plan and detects when premature direction reversals create uneven layers. This feedback enables real-time identification of uniformity issues and triggers corrective actions to restore proper layer formation.
Solution Approach 2:
The system proactively corrects placement errors by detecting premature reversals and automatically remediating them before they significantly impact layer uniformity. This preliminary correction prevents the accumulation of errors that would otherwise create unsteady layers.
3Manufacturing precision
If the control system monitors and corrects premature direction reversals to improve placement precision, then manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The control system performs self-diagnosis by automatically detecting premature direction reversals through location monitoring and work plan comparison. This self-service capability enables precision improvement without requiring external monitoring or complex manual intervention systems.
Solution Approach 2:
The system uses existing location parameters and work plan data to detect anomalies, transforming routine monitoring data into corrective actions. By leveraging existing system parameters rather than adding new sensors or complex detection mechanisms, the solution improves precision while minimizing added complexity.
