Work Machine Display Switching Using Cutoff Lever State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing work machine control systems require multiple switch presses to navigate between different display screens, leading to poor operability as operators need to repeatedly switch between driving information and camera images.
Innovation Solution
A control method and system that enables switching between an enabled and disabled state using a cutoff lever, displaying relevant screens on a display device, including a first switching process from a camera screen to a basic screen when disabled and vice versa when enabled, simplifying the navigation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single switching switch is used to navigate between display screens, then the device complexity is reduced, but the ease of operation deteriorates as operators need to press the switch multiple times to reach desired screens
Solution Approach 1:
The system performs preliminary actions by automatically switching the display screen to show camera images when the disabling operation unit is operated, without requiring the operator to press a switching switch multiple times. This anticipates the operator's need to view camera images and proactively displays them, thereby improving ease of operation while maintaining simple device architecture
Solution Approach 2:
The system incorporates feedback by detecting the operation state of the disabling operation unit and automatically adjusting the display content accordingly. When the disabling operation unit is operated, the system feedbacks by switching to camera image display, creating a responsive system that adapts to operator actions without requiring complex manual switching
2Reliability
If multiple switch presses are required to switch between driving information and camera images, then the reliability of screen switching is improved, but the loss of time increases due to repeated operations
Solution Approach 1:
The system performs the screen switching action preliminarily and automatically when the disabling operation unit is operated, eliminating the need for multiple sequential switch presses. This reduces the time required to access camera images while maintaining reliable switching through the operational state detection mechanism
3Ease of operation
If the display screen automatically switches based on operation state, then the ease of operation is improved, but the device complexity increases due to additional control logic
Solution Approach 1:
The system merges the function of the disabling operation unit with the screen switching control. By combining these functions, the system achieves automatic screen switching based on operational state without adding separate complex control mechanisms, thus improving ease of operation while minimizing the increase in device complexity

AI summary
[Problem] A work machine control method, a work machine control program, a work machine control system, and a work machine that can improve operability are provided. [Solution] The work machine control method includes displaying, on a display device, a display screen including information related to the work machine and executing at least one of a first switching process and a second switching process. The first switching process is a process in which the display screen to be displayed on the display device 2 is switched, in accordance with switching from the enabled state to the disabled state according to an operation state of a disabling operation unit, from a camera screen Dp12 that includes a captured image of a monitoring area around the work machine to a basic screen Dp11 that does not include the captured image. The second switching process is a process in which the display screen to be displayed on the display device is switched, in accordance with switching from the disabled state to the enabled state according to the operation state of the disabling operation unit, from the basic screen Dp11 to the camera screen Dp12.
