Shovel Work Display Chronological Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shovels lack a clear and understandable method to indicate how they are used, as the amount of work done varies significantly with different operational methods, making it difficult to assess fuel consumption effectively.
Innovation Solution
A shovel equipped with a cabin, a display device, and a main pump driven by internal combustion, featuring an information acquiring device and a controller that calculates and displays the amount of work per predetermined period in chronological order, using sensors and spatial recognition devices to provide a clear visual representation of work progress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If fuel consumption per unit time is displayed, then energy usage information is provided, but the understandability of work efficiency is insufficient
Solution Approach 1:
The system implements feedback by displaying work amount information alongside fuel consumption data, creating a closed-loop information system that allows operators to understand the relationship between fuel usage and actual work output, thereby improving comprehensibility of efficiency metrics
Solution Approach 2:
The display device serves multiple functions by simultaneously presenting both fuel consumption per unit time and calculated work amount information, making the system versatile in providing comprehensive operational feedback without requiring separate display systems
2Loss of information
If work amount calculation is added, then work efficiency information is provided, but device complexity increases
Solution Approach 1:
The controller automatically calculates work amount by itself using existing sensor data from the shovel's operational parameters, eliminating the need for separate measurement devices or manual input systems, thereby adding functionality while minimizing complexity increase
Solution Approach 2:
The work amount calculation function is merged into the existing controller that already manages fuel consumption monitoring, combining multiple information processing tasks into a single integrated system rather than adding separate dedicated hardware
