Construction Machinery Display Layout for Operation Pattern Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices for construction machinery do not prioritize the display of operation patterns appropriately during different stages of operation, making it difficult for operators to intuitively recognize changes in operation patterns while maintaining visibility of high-priority information.
Innovation Solution
A display control device with a first display portion for state quantity meters and a second display portion below it, displaying motor rotation speed and operating time, along with current operation pattern information, allowing operators to recognize operation pattern changes at appropriate times without interfering with high-priority displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display device shows all information simultaneously, then comprehensive information is available, but the operator cannot easily distinguish priority information during different driving stages
Solution Approach 1:
Different regions of the display device are assigned different display qualities and priorities. The first display region displays priority information (state quantities, warnings) that requires immediate attention, while the second display region displays operation pattern information. This local differentiation in display quality and priority allows the operator to easily distinguish which information requires attention at any given time, while still providing comprehensive information across both regions.
2Device complexity
If the display device uses a single display region, then the structure is simple, but it is difficult to provide prioritized display information during different driving stages
Solution Approach 1:
The display device transitions from a single display region to a multi-region display structure, adding a spatial dimension to information prioritization. By dividing the display into a first display region for priority information and a second display region for operation pattern information, the system gains the ability to adaptively prioritize different types of information during different driving stages without significantly increasing overall structural complexity.

AI summary
[Problem] To provide a display control device for construction machinery that allows an operator to intuitively recognize changes in an operation pattern at appropriate timing. [Solution] A display control device for construction machinery causes a first display portion (DpA) to display a meter (Ic1, Ic2, Ic3) indicating a state quantity of the construction machinery and causes a second display portion located below the first display portion to display a rotation speed (Ic4) of the motor of the construction machinery, an operating time (Ic5) of the construction machinery, and current operation pattern information (Ic6 ) of the construction machinery.
