Work Machine Camera Screen Switching by Disable-State Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing work machine control systems require multiple presses of a single switching switch to switch between desired screens, leading to poor operability.
Innovation Solution
A work machine control method and system that enables and disables control states based on the operation of a disabling operation unit, allowing seamless switching between a camera screen and a basic screen without the need for repeated button presses.
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 switching switch multiple times to reach the desired screen
Solution Approach 1:
The system performs preliminary action by automatically switching the display screen to the camera screen when the disabling operation unit is operated, without requiring the operator to press a switching button. This anticipates the operator's need to view the camera screen and executes the switching action in advance, improving ease of operation while maintaining simple device complexity
Solution Approach 2:
The system implements self-service by automatically changing the display content based on the operation state of the disabling operation unit. The display device monitors the operation unit's state and autonomously switches between basic screen and camera screen, eliminating the need for manual switching operations and improving operational efficiency
2Device complexity
If the display screen switches in a predetermined order with each press of the switching switch, then the device complexity is minimized, but the loss of time increases as operators wait for the desired screen to appear
Solution Approach 1:
The system executes preliminary action by pre-configuring the switching logic to directly transition to the camera screen when the disabling operation unit is activated. This eliminates the sequential switching delay and immediately presents the desired screen, reducing time loss while keeping the control system simple
Solution Approach 2:
The system uses feedback by continuously monitoring the operation state of the disabling operation unit and automatically adjusting the display screen accordingly. This closed-loop approach ensures the display responds immediately to operator intentions, minimizing time loss without increasing control system complexity

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 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 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 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 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 to the camera screen.
