Shovel Loading Display with Bar Graph and Scale Marks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shovel systems primarily display information numerically, making it difficult for operators to visually ascertain the progress of their work.
Innovation Solution
A display device for shovels that includes a hardware processor to display a bar-shaped image indicating the ratio of the loaded amount to the maximum load capacity, with scale marks representing different load ranges, enhancing visual understanding of the loading progress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If numerical information is used to display loading status, then information precision is improved, but ease of operation is worsened
Solution Approach 1:
The patent creates a visual copy (bar-shaped image) of the numerical loading status data. The bar graph visually represents the loaded amount ratio, allowing operators to quickly assess loading progress without interpreting numerical values. This visual copy maintains measurement precision while dramatically improving ease of operation.
Solution Approach 2:
The patent employs color changes in the bar-shaped image to indicate different loading stages. Scale marks are assigned different colors corresponding to different ranges of the loaded amount ratio, enabling operators to instantly grasp the loading status through color perception rather than numerical analysis.
2Loss of information
If detailed numerical data is displayed, then information completeness is improved, but device complexity is worsened
Solution Approach 1:
The patent extracts only the essential information needed for operational decision-making (the loaded amount ratio) and displays it in a simplified bar-shaped image format. While detailed numerical data is processed in the background, only the most critical visual representation is presented to the operator, reducing display system complexity while maintaining information completeness for operational purposes.

AI summary
A display device for a shovel includes a hardware processor configured to display, on the display device, a bar-shaped image indicating the ratio of the loaded amount of a load to the maximum load amount of a conveying vehicle, the load being conveyed from an end attachment included in an attachment attached to the upper swing body of the shovel to the cargo bed of the conveying vehicle. Scale marks attached to the bar-shaped image indicate scale intervals each of which is assigned to a different range of the ratio.
