Working Machine Display Layout for Clear Setting Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working machines, such as tractors, face difficulties in confirming operations when setting values are changed, and the lifting of lifting devices is not synchronized with other operation devices, leading to complex operations for operators.
Innovation Solution
A display device with candidate boxes and a contents display portion that moves to correspond with setting items, allowing operators to visually confirm setting information and simplify the operation of lifting devices by integrating it with other machine functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple buttons are provided to increase or decrease setting values, then the setting function is improved, but it becomes difficult to directly confirm how the working machine operates when the setting value is changed
Solution Approach 1:
The patent implements a feedback mechanism by displaying both the current setting value and the corresponding operation state on the display unit. When a button is pressed to change a setting value, the system immediately shows what operation will be performed or is currently performing, providing visual feedback that resolves the information loss problem while maintaining the multi-button setting functionality
2Device complexity
If only the selected setting value is displayed without showing the range, then the display is simplified, but it becomes impossible to visually know which value is selected within the range between maximum and minimum values
Solution Approach 1:
The patent segments the display into multiple components: the setting value range (minimum to maximum) is displayed separately from the currently selected value. This segmentation allows the display to show both the full range context and the specific selected value clearly, preventing information loss while maintaining relative simplicity
3Ease of operation
If the lifting device operates independently without synchronization with other operation devices, then the lifting control is simplified, but the operator must change revolving speed of the prime mover and other parameters manually, making the operation complex
Solution Approach 1:
The patent merges the lifting device control with other operation device controls through a unified control system. The lifting device is no longer independent but is integrated with the prime mover speed control and other operational parameters, allowing synchronized adjustment through a single operation interface that reduces overall operational complexity

AI summary
A display device (50) for a working machine (1), includes: a plurality of candidate boxes (140) in which candidate setting information to be set to the working machine (1) is represented, the candidate boxes (140) being displayed on a screen; and a contents display portion (141) in which a setting item relating to the working machine (1) is displayed. The display device (50) is characterized in that the display device (50) includes a display control portion (56) to move a display box to a position corresponding to the contents display portion (141) in performing the setting to the working machine (1), the display box being one of the plurality of candidate boxes (140) in which candidate setting information corresponding to the setting is displayed.
