Depth Indicators for Shovel Training Simulator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Real-world training for operators of industrial machines like shovels is challenging due to the difficulty in providing proper depth perspectives in two-dimensional computer-based simulators, which limits the effectiveness of operator training for tasks such as digging and loading materials.
Innovation Solution
A simulated training environment is generated using a processor, including a simulated shovel and dipper, with indicators providing depth-related information, such as level-grade plane detection and shovel-to-truck alignment, to alert operators of improper positioning and enhance their training experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a two-dimensional monitor or screen is used to display the training environment, then the device complexity is reduced and ease of operation is improved, but the depth perspective and spatial accuracy deteriorate
Solution Approach 1:
The patent overlays depth-related information indicators on the two-dimensional display to provide third-dimensional spatial context. Virtual indicators such as depth markers, level-grade plane indicators, and swing path indicators are superimposed on the 2D screen to convey depth information that would otherwise require 3D visualization, effectively adding a dimensional layer of information to the flat display.
Solution Approach 2:
The patent introduces virtual indicators as intermediary elements between the operator and the simulated environment. These indicators act as mediators that translate complex spatial relationships into simplified visual cues on the 2D display, such as color-coded depth zones and alignment indicators, allowing operators to perceive depth information without requiring true 3D visualization.
2Measurement precision
If real-world or on-site training is provided, then the training effectiveness and depth perspective accuracy are improved, but the training cost and time consumption increase
Solution Approach 1:
The patent creates a virtual copy of the real-world shovel operating environment through a simulated training environment that replicates key spatial relationships, equipment geometry, and operational contexts. This virtual copy includes digital models of shovels, haul trucks, banks, and terrain, allowing operators to practice in a realistic setting without the time and resource constraints of physical field training.
Solution Approach 2:
The patent enables operators to perform preliminary training actions in the simulated environment before transitioning to real equipment. By practicing digging operations, dipper positioning, and material loading in the virtual simulator with depth indicators, operators develop spatial awareness and operational skills in advance, reducing the training time required when working with actual shovels.
3Measurement precision
If depth-related indicators are added to the simulated training environment, then the depth perspective accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent employs color-coded indicators to convey depth information efficiently. Different colors represent different depth zones or spatial relationships, such as green for acceptable depth ranges, yellow for warning zones, and red for prohibited areas. This color-coding system provides intuitive depth feedback without requiring complex visual displays or additional hardware.
Solution Approach 2:
The patent divides the simulated environment into discrete depth zones and spatial regions that are independently marked with indicators. Rather than attempting to display continuous three-dimensional depth information, the space is segmented into manageable zones with specific indicator markers, simplifying the overall system while maintaining effective depth communication.

AI summary
Systems and methods for training an operator. One system includes a computing device including a processing unit and computer-readable medium. The computer-readable medium stores a training simulator application. The training simulator application, when executed by the processing unit, is configured to (i) receive an operating command from the operator, (ii) generate a simulated working environment and a simulated shovel having a simulated dipper, the simulated shovel and the simulated dipper positioned within the simulated working environment based on the operating command, (iii) generate an indicator providing depth-related information to an operator relating to a position of the simulated dipper with respect to a point-of-reference within the simulated working environment, and (iv) output the simulated working environment and the indicator to at least one output device for display to the operator.
