Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for loading materials onto conveyance vehicles, such as dump trucks, lack efficient automatic control coordination between work machines and conveyance vehicles, leading to suboptimal loading operations.
Innovation Solution
A system comprising a work machine and a conveyance vehicle with position sensors and processors that communicate to determine and adjust a target stop position for the conveyance vehicle based on the work machine's position and offset distance, enabling precise automatic control and coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic control is implemented for loading work, then loading efficiency is improved, but coordination between work machine and conveyance vehicle deteriorates
Solution Approach 1:
The patent merges the control systems of the work machine and conveyance vehicle into a unified automatic control system. The controller of the work machine receives position information from both its own position sensor and the conveyance vehicle's position sensor, enabling coordinated automatic control of both machines during loading operations without requiring separate manual operations.
Solution Approach 2:
The patent introduces position sensors as intermediary devices that provide real-time position data to the controller. The work machine's controller uses this intermediary position information from both machines to calculate appropriate movements and maintain proper coordination, enabling automatic control while preserving reliable coordination between the work machine and conveyance vehicle.
2Reliability
If manual operation is used for loading work, then coordination between work machine and conveyance vehicle is maintained, but loading efficiency deteriorates
Solution Approach 1:
The system enables self-service automatic control where the work machine's controller autonomously manages the loading operation by integrating position data from both machines. The controller automatically determines the appropriate movements and coordination without requiring manual intervention, allowing the system to serve itself while maintaining efficient and coordinated loading operations.
3Ease of operation
If conveyance vehicle position is not precisely controlled, then operational flexibility is maintained, but loading precision deteriorates
Solution Approach 1:
The patent implements dynamic position control for the conveyance vehicle by continuously receiving real-time position data from its position sensor and feeding it to the work machine's controller. This dynamic information flow allows the system to adapt to the conveyance vehicle's actual position while maintaining precise loading control, balancing operational flexibility with loading precision through continuous adjustment.
Data Source
AI summary
A system includes a conveyance vehicle, and a work machine that loads materials onto the conveyance vehicle. A first processor of a work machine determines a target stop position of a conveyance vehicle based on a position of the work machine, a target offset distance, and the direction of the loading position. A second processor of the conveyance vehicle acquires data indicative of the target stop position of the conveyance vehicle from the work machine. The second processor controls the conveyance vehicle to move the conveyance vehicle to the target stop position.
