Work Machine Auto-Travel Control Using Screen-Aware Button Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional work machines with multiple functions on a single operation unit face difficulties in user understanding, leading to unintended operations due to confusion on which function is being executed, posing a risk of unintended actions.
Innovation Solution
Implementing an operation control method and system that differentiates actions based on the displayed screen on the operation terminal, executing specific actions only when the relevant screen for automatic steering is displayed, and transitioning screens to ensure the user is aware of the operation being performed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple functions are assigned to one operation unit, then the device complexity is reduced and ease of operation is improved, but the reliability deteriorates due to user confusion and unintended operations
Solution Approach 1:
The system provides visual feedback by displaying different icons or indicators on the operation screen corresponding to different display screens. When a specific display screen is active, its associated icon is highlighted or shown, giving the user immediate feedback about which function will be executed when the operation unit is pressed. This prevents unintended operations by ensuring the user knows the current function before activation.
2Device complexity
If multiple functions are assigned to one operation unit, then the device complexity is reduced, but the difficulty of detecting and measuring the current function increases
Solution Approach 1:
The system uses visual indicators such as different colors, icons, or display states to represent different active functions. When a particular display screen is active, its corresponding visual indicator changes appearance (e.g., color, brightness, or icon display), making it easy for the user to detect which function is currently active without increasing device complexity.
3Adaptability or versatility
If the operation unit executes different actions based on the displayed screen, then the adaptability is improved, but the device complexity increases due to conditional logic
Solution Approach 1:
The operation unit is designed as a universal control element that can trigger different functions depending on the active display screen. The control unit automatically determines which function to execute based on which display screen is currently active, allowing one operation unit to serve multiple purposes without requiring complex additional hardware or switches.

AI summary
A vehicle control device causes the work machine to execute automatic travel when an automatic travel button is operated by an operator in a state where a guidance screen relating to automatic travel of a work machine is displayed on an operation terminal, and does not cause the work machine to execute automatic travel when the automatic travel button is operated by the operator in a state where a non-guidance screen is displayed on the operation terminal.
