Automatic Loading Control with Work-Machine Readiness Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic loading systems fail to properly assess the readiness of a work machine for loading operations, leading to improper control when a carrier approaches, even when the machine is not in a suitable state.
Innovation Solution
An automatic loading system that includes a position detection unit, controller, and external system, allowing an operator or AI to determine the validity of starting loading control through input signals and display of detection results, ensuring the work machine is in a suitable orientation and position before initiating loading operations.

Engineering Contradiction Analysis
1Productivity
If the controller automatically starts loading control when a carrier approaches, then loading operations can be performed efficiently, but loading control may start improperly when the work machine is not in a suitable state
Solution Approach 1:
The system performs preliminary assessment of the work machine's state (position, orientation, operational status) before initiating loading control. The determination subject evaluates whether the work machine is in a suitable state to perform loading, and only starts loading control when the assessment is positive, preventing improper loading attempts while maintaining efficient operation when conditions are favorable.
2Device complexity
If the controller alone determines when to start loading control, then the system remains simple, but there is no independent verification of loading readiness
Solution Approach 1:
The invention introduces a determination subject that acts as an intermediary between the carrier approach detection and the loading control execution. This determination subject independently assesses whether the work machine is in a suitable state for loading, providing verification beyond the controller's basic detection, thereby improving reliability without significantly complicating the overall system structure.

AI summary
A controller (50) is installed in a work machine (20) and configured to perform loading control based on a detection result of a position detection unit (41). An external system (70) is arrangeable outside the work machine (20) and communicable with the controller (50). The external system (70) is configured to output a loading control start signal for starting the loading control. The controller (50) starts the loading control on condition that the loading control start signal has been input from the external system (70) to the controller (50).
