Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If travel paths are calculated without considering work information from preceding vehicles, then calculation simplicity is maintained, but work efficiency decreases due to perpendicular or skewed paths
Solution Approach 1:
The system performs preliminary acquisition and storage of work information from preceding field work vehicles before calculating the travel path for subsequent vehicles. This advance preparation enables the path calculation to consider actual field conditions created by previous operations, optimizing the subsequent vehicle's travel path to avoid perpendicular or skewed routes that reduce work efficiency
Solution Approach 2:
The system establishes a feedback loop where work information from preceding vehicles is continuously acquired, stored, and used to inform travel path calculations for subsequent vehicles. This feedback mechanism ensures that each vehicle's path is optimized based on the cumulative work state of the field, improving overall productivity while managing system complexity through structured information flow
2Productivity
If work information from preceding vehicles is acquired and utilized, then travel path optimization is achieved, but information management complexity increases
Solution Approach 1:
The system introduces a travel path generation device as an intermediary component that mediates between the work information from preceding vehicles and the subsequent vehicle's path calculation. This intermediary device processes, stores, and retrieves work information systematically, enabling travel path optimization without directly increasing the complexity of individual vehicle systems
Solution Approach 2:
The system creates and utilizes copies of work information from preceding vehicles in a structured database format. Rather than requiring direct communication between vehicles, the system copies relevant work state data (such as ridgeline information, harvested areas, and field conditions) into a centralized storage system that can be efficiently queried during path calculation, reducing information management complexity
3Productivity
If perpendicular or skewed travel paths are used, then path calculation simplicity is maintained, but work efficiency decreases
Solution Approach 1:
The system changes the parameters used in path calculation from fixed geometric patterns (perpendicular or skewed angles) to dynamic parameters based on actual field conditions. By incorporating work information such as ridgeline orientations, harvested area boundaries, and field-specific features, the path calculation adapts to optimize travel efficiency while maintaining computational feasibility through structured parameter management

AI summary
A slip determination system is provided that is capable of providing appropriate control information to a traveling vehicle when the traveling vehicle has proceeded to an area where a slip is likely to occur during automatic travel. The slip determination system includes: a vehicle position detection module for detecting a vehicle position; and an automatic travel control portion for enabling automatic travel based on the vehicle position and a set travel path; a slip amount calculation portion for calculating a slip amount of the traveling vehicle body, using an estimated movement distance of the traveling vehicle body calculated based on the number of revolutions of a driving axle of the traveling vehicle body, and an actual movement distance of the traveling vehicle body calculated based on the vehicle position; an appropriateness determination portion for performing appropriateness determination to determine, based on the slip amount, whether or not a state of a traveling ground surface is appropriate for automatic travel; and an automatic travel stop portion for stopping automatic travel based on a determination result.
