Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Work vehicles face challenges in accurately updating ridge-adjacent positions during automatic travel in deformed fields, leading to inappropriate notifications, which requires complex operations to reset reference points.
Innovation Solution
A work vehicle equipped with a control unit that can dynamically change control reference positions using a satellite positioning system, allowing for flexible updates of ridge-adjacent positions during both automatic and manual travel, enabling proper notification without interrupting operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reference route is generated based on fixed point A and point B, then the automatic travel can be performed extensively in regular fields, but the notification becomes inaccurate in deformed fields requiring complex resetting operations
Solution Approach 1:
The patent applies dynamics by enabling the reference route to be dynamically updated during automatic travel. The control unit allows re-setting of point A or point B based on the vehicle's current position and detected ridge-adjacent positions, transforming the previously static reference route into a dynamic one that adapts to field deformations without requiring manual intervention to reset both points
Solution Approach 2:
The system applies self-service by automatically detecting ridge-adjacent positions using the satellite positioning system and autonomously determining when to update the reference route. The control unit monitors the vehicle position continuously and automatically triggers reference point updates based on predetermined conditions, eliminating the need for manual operation to reset reference points in deformed fields
2Reliability
If the point A and point B are reset frequently to update ridge-adjacent positions in deformed fields, then the notification accuracy improves, but the operation time and complexity increase
Solution Approach 1:
The patent ensures continuity of useful action by allowing the automatic travel to continue uninterrupted while the reference route is updated. The control unit performs dynamic updates of point A or point B during ongoing automatic travel based on satellite positioning data, eliminating the need to stop and manually reset both reference points, thus maintaining continuous work while improving notification accuracy
Solution Approach 2:
The system applies preliminary action by pre-establishing the relationship between vehicle position and ridge-adjacent positions using satellite positioning before notification is needed. The control unit continuously monitors position data and proactively updates the reference route when predetermined conditions are met, ensuring accurate notification is ready in advance rather than requiring reactive manual resetting

AI summary
A rice transplanter 1 is configured so as to be capable of, while utilizing a satellite positioning system to specify the rice transplanter position, autonomous travel along a travel route set parallel to a reference route SC generated on the basis of preset points A and B. The rice transplanter 1 is provided with a control unit that, during autonomous travel, activates a notification device if the rice transplanter position approaches a ridge-adjacent position L1 specified on the basis of point A or a ridge-adjacent position L2 specified on the basis of point B. The control unit is configured so as to be capable of changing one of the ridge-adjacent position L1 and ridge-adjacent position L2 to a ridge-adjacent position L3 specified on the basis of a point P different from points A and B. After said change, the control unit activates the notification device on the basis of the ridge-adjacent position L3 instead of said one of the ridge-adjacent position L1 and ridge-adjacent position L2.
