Shovel Display Monitor Fuel Efficiency Graph Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of shovels cannot view fuel efficiency information on display monitors during operation due to the need to switch screens, which requires releasing the operation lever and is impractical during work.
Innovation Solution
A display system that simultaneously displays fuel efficiency graphs with different time axes and operational work modes on a single screen, allowing operators to monitor fuel efficiency without releasing the operation lever.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display monitor shows multiple screens for different information, then the information completeness is improved, but the ease of operation deteriorates because the operator must release the operation lever to switch screens
Solution Approach 1:
The patent combines multiple information screens (fuel efficiency graph, work mode display, and other operational data) into a single integrated display screen. This allows the operator to view all necessary information simultaneously without switching between multiple screens, thereby maintaining ease of operation while preventing loss of information.
Solution Approach 2:
The patent utilizes the spatial dimension of the display screen by arranging multiple information elements (fuel efficiency graphs with different time axes, work mode indicators, and other parameters) in a multi-dimensional layout on a single two-dimensional screen. This enables comprehensive information display without requiring additional screens or interrupting the operator's workflow.
2Measurement precision
If the display monitor shows comprehensive fuel efficiency data, then the measurement precision is improved, but the device complexity increases due to multiple screen switching requirements
Solution Approach 1:
The patent merges multiple display functions and information layers into a single integrated display interface, eliminating the need for multiple physical screens or complex screen switching mechanisms. This reduces device complexity while maintaining comprehensive fuel efficiency monitoring capabilities with high measurement precision.
3Loss of information
If the operator releases the operation lever to check display information, then the information accessibility is improved, but the productivity decreases due to work interruption
Solution Approach 1:
The patent presents all necessary fuel efficiency information and work mode data in advance on a single display screen, organized in a manner that allows the operator to quickly grasp key metrics without needing to switch screens or search for information. This enables the operator to access comprehensive data instantly while maintaining continuous control of the operation lever, thereby preventing work interruption and maintaining productivity.

AI summary
A shovel includes a cabin in which a display monitor is provided, a main pump that generates a hydraulic pressure, an internal combustion engine that drives the main pump, and a display control part configured to generate display information to be displayed on the display monitor based on information communicated between the display control part and the internal combustion engine, and cause the generated display information to be displayed on the display monitor. The display control part is configured to cause a graph showing the fuel efficiency of the internal combustion engine over time and the operational work mode of the shovel corresponding to a time for which the fuel efficiency is calculated to be simultaneously displayed on the single display screen of the display monitor.
