Automated ADT Dump Control for Stable Material Spread
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Articulated dump trucks face challenges in achieving an even spread of loads during unloading, requiring additional labor and time, and stability issues during tipping, which increase fuel costs and reduce vehicle utilization.
Innovation Solution
A transport vehicle with a chassis, wheel assemblies, a load bin, and load bin actuators controlled by a system that considers vehicle speed, inclination, load weight, and material type to optimize load spreading and stability, allowing for automated and efficient unloading while ensuring stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ADT unloads material without automated control, then the unloading process is simple, but the load spread is uneven requiring additional labor and time
Solution Approach 1:
The system enables the ADT to automatically control its own dumping operation by using sensors to detect material characteristics and automatically adjusting the dump bed angle and actuator speed to achieve even material distribution without operator intervention
Solution Approach 2:
The patent replaces manual mechanical operation with an automated control system that uses sensors, processors, and actuators to detect material properties and dynamically adjust the dumping process, substituting human judgment and manual control with automated electronic control
2Productivity
If the ADT increases unloading speed to reduce cycle time, then fuel costs decrease, but stability during tipping is compromised
Solution Approach 1:
The system dynamically adjusts the dump bed angle and actuator speed based on real-time detection of material characteristics and vehicle conditions, allowing the unloading process to adapt its parameters to maintain stability while optimizing speed for each specific situation
Solution Approach 2:
The patent implements a feedback control system where sensors continuously monitor material properties and vehicle status during dumping, and the processor uses this information to automatically adjust actuator commands to maintain both speed and stability
3Manufacturing precision
If the ADT stops to unload material, then the load can be spread evenly, but the unloading time increases
Solution Approach 1:
The system enables continuous unloading operation by automatically controlling the dump bed movement to distribute material evenly while the vehicle remains in motion or maintains minimal movement, eliminating the need to stop and manually spread material
