Work-Travel Sequence Icon Management for Agricultural Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driving support systems for traveling work vehicles, such as tractors and combine harvesters, face challenges in managing multiple sequences of operations during headland turns, making it difficult for drivers to understand and execute complex sequences, especially when dealing with a mixture of different operations and unclear distance or time intervals.
Innovation Solution
A driving support system that includes a device controller, display, storing means, read-out means, screen processor, and work-travel managers to manage multiple work-travel sequences on a single screen, converting control data into icons for easy understanding and editing, with attributes like work time and travel distance assigned to each icon for precise timing, and selection buttons to navigate through sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple work-travel sequences are managed using traditional display methods showing only ordinal numbers, then the system can store and execute multiple sequences, but the driver cannot accurately understand the content and timing of each sequence
Solution Approach 1:
The patent creates visual copies of sequence information through icons that represent each operation. Instead of displaying abstract ordinal numbers, the system generates graphical representations (icons) that copy and visualize the actual operation content, making it comprehensible to the driver while maintaining the capability to manage multiple sequences
Solution Approach 2:
The patent transforms one-dimensional ordinal number displays into two-dimensional visual displays with icons arranged spatially. By adding visual dimensions (graphics, positioning, icons) to the display, the system preserves multi-sequence management capability while dramatically improving information comprehension
2Ease of operation
If distance intervals or time intervals of operations are not displayed, then the system can simplify the display interface, but the driver cannot accurately understand the timing and spacing of operations
Solution Approach 1:
The patent segments the sequence information into distinct visual elements: icons representing operations and separate visual indicators for distance/time intervals. This segmentation allows the display to maintain simplicity through modular presentation while providing precise timing and spacing information through dedicated visual segments for each parameter
3Device complexity
If only a number of selected sequence is displayed, then the system can reduce display complexity, but the driver cannot understand the content of the sequence
Solution Approach 1:
The patent uses visual characteristics including icons and their arrangements to encode sequence content information. Different icons represent different operation types, and their visual presentation provides content understanding while maintaining display simplicity through standardized visual symbols
Solution Approach 2:
The system creates visual copies of operation content through icons that represent each step. These graphical representations copy the essential meaning of each operation, allowing the driver to understand sequence content without displaying complex textual or numerical information

AI summary
A driving support system includes a device control unit that outputs operation control signals to a travel operation device causing a traveling vehicle body to travel and a work operation device causing a ground work apparatus to operate. A recorder records control data in execution processing order as a work-travel sequence. A readout means reads out the control data recorded by the recorder and transmits the control data to the device control unit. A screen processor converts the control data for each execution processing unit to an icon and displays in a display a work-travel sequence screen displaying the icon in the execution processing order. The system manages a plurality of the work-travel sequences on the same work-travel sequence screen.
