Work Machine Display Switching by Movement State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work machine control systems require multiple switch presses to switch between display screens, leading to poor operability.
Innovation Solution
A work machine control method that switches display screens based on a predefined pattern and adjusts this pattern according to the machine's movement state, using a switching operation unit and processors to manage the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single switching switch is used to cycle through display screens in a predetermined order, then the display screen can be switched among multiple modes, but the operability deteriorates because operators need to press the switching switch many times to reach the desired screen
Solution Approach 1:
The patent applies the Dynamics principle by making the switching pattern adaptive rather than fixed. The control unit dynamically changes the switching sequence based on the detected operation state of the work machine. When the machine is traveling, the system cycles through screens in a travel-oriented sequence; when working, it uses a work-oriented sequence. This dynamic adaptation reduces the number of presses needed to reach relevant screens, directly improving operability while maintaining versatility.
Solution Approach 2:
The patent implements Parameter changes by modifying the switching pattern parameter based on the operation state. The control unit detects whether the machine is in travel or work mode and changes the screen switching sequence parameter accordingly. This allows the same switching switch to provide different switching behaviors appropriate to each operational context, reducing unnecessary presses and improving ease of operation without sacrificing the ability to access all display screens.
2Loss of information
If multiple display screens are provided for different work machine information, then comprehensive information can be displayed, but the device complexity increases due to the need for multiple switching mechanisms
Solution Approach 1:
The patent applies the Universality principle by designing a single switching switch that performs multiple functions. Instead of providing separate switching mechanisms for different screen groups, one switch handles all screen transitions by adapting its switching pattern based on the detected operation state. This multi-functional approach maintains comprehensive information display capability while significantly reducing device complexity by eliminating redundant switching components.
