Work Machine Display Switching via Disable-State Camera Screen Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing work machines require multiple switch presses to switch between desired display screens, leading to poor operability for operators.
Innovation Solution
Implement a control method and system that enable and disable machine control based on a disabling operation unit, allowing seamless switching between camera and basic screens using first and second switching processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single switching switch is used to switch between display screens in a predetermined order, then the device complexity is reduced, but the ease of operation deteriorates because operators need to press the switch multiple times to reach the desired screen
Solution Approach 1:
The system pre-establishes multiple display modes (first display mode showing camera images, second display mode showing work machine information) and automatically switches between them based on the operation unit state, eliminating the need for operators to manually press switches multiple times to navigate through screens
Solution Approach 2:
The display device automatically adjusts its output based on feedback from the operation unit state (enabled/disabled), creating a responsive system that changes display content according to operational context without requiring manual intervention
2Device complexity
If the display screen switches in a predetermined order with each press of the switching switch, then the device complexity is reduced, but the loss of time increases as operators wait to reach the desired screen
Solution Approach 1:
The system prepares multiple display modes in advance and automatically selects the appropriate mode based on the operation unit state, eliminating the time-consuming sequential switching process and allowing immediate access to relevant information
Solution Approach 2:
The display mode dynamically changes based on the operational state (enabled/disabled), adapting to current needs in real-time rather than following a fixed predetermined sequence, thus reducing time loss
3Loss of information
If the display device shows camera screens during disabled state, then the monitoring capability is maintained, but the reliability decreases due to risk of unintended machine movements
Solution Approach 1:
The display content is segmented into different modes: the first display mode shows camera images for monitoring during disabled state, while the second display mode shows work machine information during enabled state, separating monitoring functions from control functions to prevent confusion and ensure safety
Solution Approach 2:
The system preemptively changes display content based on the operation unit state to prevent potential safety issues - by showing only work machine information (not camera screens) when the machine is enabled for operation, it eliminates the risk of unintended movements caused by operator distraction or confusion

AI summary
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 either a first switching process or a second switching process. The first switching process is a process that the display screen displayed on the display device is switched, according to switching from the enabled state to the disabled state according to an operation state of a disabling operation unit, from a camera screen that includes a captured image of a monitoring area around the work machine to a basic screen that does not include the captured image. The second switching process is a process that the display screen displayed on the display device is switched, according to switching from the disabled state to the enabled state according to the operation state of the disabling operation unit, from the basic screen to the camera screen.
