Shovel Display Device 3D Bucket Attitude Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shovel operators have difficulty intuitively understanding the attitude of the bucket due to multiple display formats and limited time to view the display screen during operation.
Innovation Solution
A shovel with a display device that shows the bucket's attitude information in a three-dimensional model, allowing for intuitive understanding without requiring constant focus on the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple display formats (side view, front view) are used to show bucket attitude information, then the information completeness is improved, but the ease of understanding deteriorates
Solution Approach 1:
The patent combines multiple view formats (side view, front view, and top view) into a single integrated three-dimensional model display. This merging allows the operator to perceive complete bucket attitude information from multiple angles simultaneously within one unified visual representation, eliminating the need to switch between separate display formats and improving both information completeness and ease of understanding.
Solution Approach 2:
The patent transitions from two-dimensional display formats to a three-dimensional model display. By adding the third dimension, the system enables intuitive spatial understanding of bucket attitude while maintaining information completeness. The three-dimensional model naturally incorporates side, front, and top perspectives in a single visualization, resolving the contradiction between providing comprehensive information and ensuring ease of understanding.
2Measurement precision
If the operator focuses on the display screen to check bucket attitude, then the accuracy of understanding is improved, but the productivity deteriorates
Solution Approach 1:
The three-dimensional model provides intuitive spatial representation that allows operators to quickly grasp bucket attitude without prolonged screen observation. The added dimension creates a natural, easy-to-interpret visual format that maintains high accuracy of understanding while reducing the time needed to interpret the display, thereby improving operational efficiency.
Solution Approach 2:
The patent employs color coding in the three-dimensional model to highlight different aspects of bucket attitude (such as different colors for different angular measurements or status indicators). This visual enhancement allows operators to rapidly extract accurate information from the display without needing to study the screen extensively, thus maintaining measurement precision while improving productivity.
