Construction Machinery Display Layout for Operation Pattern Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices for construction machinery do not prioritize the display of operation patterns effectively during different stages of operation, making it difficult for operators to intuitively recognize changes in operation patterns at the appropriate timing.
Innovation Solution
A display control device with a first display portion showing state quantities and a second display portion showing motor rotation speed and operation pattern information, where operation pattern information is displayed below the state quantities, allowing operators to recognize changes in operation patterns without interfering with high-priority displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display shows all information simultaneously, then comprehensive information is provided, but the operator cannot easily distinguish priority information during different operation stages
Solution Approach 1:
The patent applies local quality by giving different display regions different functions and visual characteristics. The first display region displays state quantities with high visibility, while the second display region displays operation pattern information in a differentiated manner. This local differentiation allows the operator to easily distinguish priority information while maintaining comprehensive information display.
Solution Approach 2:
The display control device dynamically adjusts the display content and priority based on the current operation stage. During different operation phases (starting, running, stopping), the system can emphasize different information types, making priority recognition easier while maintaining comprehensive information availability.
2Loss of information
If operation pattern information is displayed prominently, then changes in operation pattern are easily recognized, but the display layout becomes complex and may interfere with other critical displays
Solution Approach 1:
By segmenting the display into distinct regions, the patent simplifies the overall layout complexity. The operation pattern information is confined to a specific second display region, preventing it from interfering with other critical displays while maintaining easy recognition of operation pattern changes through dedicated display space.

AI summary
A display control device for construction machinery causes a first display portion to display a meter 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 of the motor of the construction machinery, an operating time of the construction machinery, and current operation pattern information of the construction machinery.
