Work Machine Operation Pattern Display for Safer Control Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work machines face an increased burden due to the need for visual inspection of operation patterns, which can lead to unexpected machine movements if the checking operation is neglected.
Innovation Solution
A method and system that provides operation pattern information through a display device, allowing operators to change patterns easily by displaying screens that show current operations and enable pattern changes, reducing the reliance on visual inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operators visually inspect the switch lever position to check operation patterns, then they can verify the current pattern, but this increases the operational burden and risk of unexpected machine movements
Solution Approach 1:
The patent replaces the mechanical visual inspection method with an electronic display system. The display device shows operation pattern information on the operation screen, allowing operators to verify patterns without physically checking the switch lever position. This substitution of mechanical inspection with electronic information display reduces operational burden while maintaining verification reliability
Solution Approach 2:
The patent introduces an intermediary information display system between the operator and the operation pattern. Instead of direct visual inspection of the switch lever, the display device acts as an intermediary that presents pattern information in an accessible format on the operation screen, reducing the complexity of the verification process
2Ease of operation
If the operation pattern information is displayed on the operation screen, then operators can easily access pattern information, but this requires additional display and control system components
Solution Approach 1:
The patent makes the existing operation screen serve multiple functions: it displays both the operation pattern information and the actual operation patterns. By utilizing the existing display infrastructure for dual purposes, the system provides accessible pattern information without adding separate dedicated display devices, thereby limiting the increase in system complexity
Solution Approach 2:
The patent merges the pattern information display function with the existing operation screen. Instead of creating a separate display system, the control device integrates pattern information presentation into the already-present operation screen, combining multiple functions into a single interface to avoid increasing overall device complexity

AI summary
A method of controlling a work machine is a method of controlling the work machine provided with a machine body that moves according to an operation device operation and that is capable of changing an operation pattern which is a correspondence between the operation device operation and the machine body movement. The control method has presenting the operation pattern information, which shows the current operation pattern, at the time of switching from a state in which the machine body fails to move according to the operation device operation to a state in which the machine body moves according to the operation device operation.
