Remote Work Vehicle Bucket Height Notification via Virtual 3D Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote operation of work vehicles, operators struggle to accurately recognize the bucket height due to the lack of tactile feedback, leading to potential inefficiencies in operations like excavation and loading.
Innovation Solution
A bucket height notification device that includes a bucket height specification unit to calculate the height from the ground to the bucket and a notification unit to inform the operator, using sensors and display devices to provide visual and potentially haptic feedback of the bucket height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote operation is implemented using two-dimensional images, then the operator can operate the work vehicle from a distance, but the operator cannot recognize the bucket height with a sense of perspective
Solution Approach 1:
The patent creates a virtual three-dimensional space that copies and reconstructs the physical work environment. By generating a virtual model of the bucket and ground based on sensor data (GPS, inclination sensors, depth sensors), the system provides the remote operator with a realistic three-dimensional visualization that replicates the spatial relationships and bucket height information as if the operator were physically present in the work vehicle.
2Ease of operation
If remote operation is implemented without tactile feedback, then the operator can operate from a distance, but the operator cannot feel vibrations to recognize bucket height
Solution Approach 1:
The patent implements multiple feedback mechanisms to compensate for the lack of tactile feedback in remote operation. Depth sensors continuously measure the actual distance between the bucket and ground, providing real-time data feedback. The system also uses vibration sensors to detect when the bucket touches the ground, and this information is transmitted to the operator through the control interface, creating a closed-loop feedback system that enables precise bucket height control without direct tactile sensation.
3Loss of information
If three-dimensional visualization is added to remote operation interface, then the operator can recognize bucket height with perspective, but the device complexity increases
Solution Approach 1:
The patent makes existing components perform multiple functions to minimize additional complexity. The display device that originally showed only two-dimensional camera images is enhanced to simultaneously render three-dimensional virtual models of the bucket and ground. The control device integrates multiple sensor inputs (GPS, inclination, depth) and processes them to generate both the visual three-dimensional representation and the operational control signals, making the system multi-functional without requiring completely separate dedicated components for each function.

AI summary
A bucket height notification device includes a bucket height specification unit and a bucket height notification unit. The bucket height specification unit specifies a bucket height from a ground surface to a bucket of work equipment included in a work vehicle related to remote operation. The bucket height notification unit notifies of the bucket height.
