Work Machine Display Layout for Blade and Ripper Camera Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for work machines, such as crawler dozers, face challenges in displaying a large amount of information effectively, as displaying multiple images reduces the data quality of each image, making it difficult to select and view relevant data during different operations like excavation and ripping.
Innovation Solution
A display system for work machines that includes multiple cameras and a display control unit, which sets divided display sections to showcase images from specific camera groups corresponding to different work implements, such as the excavating blade and ripper, allowing for increased information display without reducing image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data of multiple captured images are displayed on the display screen simultaneously, then the amount of information displayed is increased, but the data quality and information content of each individual captured image is reduced
Solution Approach 1:
The display screen is divided into multiple display regions, with each region dedicated to showing data from a specific camera. This segmentation allows multiple images to be displayed simultaneously without reducing the quality or information content of individual images, as each image is displayed in its own dedicated region rather than being compressed into a shared space
2Quantity of substance
If data of all captured images are displayed on the display screen, then the amount of information is increased, but it becomes difficult to select and view specific relevant data
Solution Approach 1:
Each display region is assigned specific functional characteristics based on the work implement it corresponds to (e.g., first display region for excavating blade, second display region for ripper). This local quality differentiation allows operators to easily identify and select relevant data by knowing which region corresponds to which work implement, making information retrieval intuitive and efficient
3Ease of operation
If the same in-vehicle camera data is displayed regardless of work type, then the system is simple to operate, but the information displayed is not optimized for different work operations
Solution Approach 1:
The display control unit dynamically changes the displayed camera data based on the current work implement in use. When the excavating blade is being used, the first camera group data is displayed; when the ripper is being used, the second camera group data is displayed. This dynamic adaptation maintains ease of operation while ensuring the displayed information is always relevant to the current work operation
Solution Approach 2:
The system uses feedback from the work implement status (which implement is currently being used) to automatically select and display the appropriate camera group data. This feedback mechanism ensures that the displayed information is always optimized for the current work operation without requiring manual intervention from the operator
Data Source
AI summary
An amount of information of data of a captured image displayed on a display unit is increased. A display control unit sets a plurality of divided display sections for a display unit. The display control unit sets a first camera group and a second camera group including one or more of a plurality of cameras. The first camera group captures an image of a work performed with a blade. The second camera group captures an image of a work performed with a ripper. The display control unit displays data of captured images output from cameras included in one of the first and second camera groups in a corresponding plurality of divided display sections.
