Work Vehicle Route Selection to Prevent Repetitive Topsoil Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Work vehicles performing automatic traveling on predetermined routes for spraying chemicals on crops consistently damage the topsoil due to repetitive travel paths, leading to soil degradation.
Innovation Solution
A route determination method and system that generates multiple candidate routes for work vehicles to travel along, allowing selection of a first candidate route as the target route, which deviates from previous paths to minimize soil damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the work vehicle travels along a predetermined target route for automatic traveling, then the work vehicle can perform automatic traveling while performing work on work target objects, but the topsoil of the work site is damaged due to repetitive travel paths
Solution Approach 1:
The patent applies dynamics by making the target route changeable rather than fixed. The route determination device dynamically adjusts the target route based on storage data that records previous travel paths, ensuring that the work vehicle travels on different routes in subsequent work sessions. This dynamic route adjustment maintains automatic traveling capability while preventing repetitive soil damage.
Solution Approach 2:
The patent changes the parameter of route position by determining a new target route that differs from previous routes. The route determination device modifies route parameters by selecting alternative paths from multiple candidate routes, changing the traveling position parameter to avoid repeated traversal of the same soil areas, thereby preventing topsoil damage while maintaining automation.
2Productivity
If the work vehicle travels on the same place every time, then automatic traveling can be performed efficiently, but the topsoil is damaged due to repetitive paths
Solution Approach 1:
The system maintains high productivity by implementing dynamic route selection that adapts to previous travel patterns. The route determination device efficiently selects alternative routes based on stored data, ensuring that work continues without interruption while naturally varying the travel paths to prevent soil damage, thus maintaining productivity without repetitive harm.
Solution Approach 2:
The patent implements feedback by using storage data that records previous target routes and incorporating this information into subsequent route determination. The system receives feedback from past traveling patterns and adjusts future routes accordingly, selecting paths that avoid previously traversed areas, thereby preventing soil damage while maintaining efficient work progression.
3Object-affected harmful factors
If multiple candidate routes are generated and a first candidate route is selected as the target route, then repetitive soil damage is prevented, but the system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the route determination process into distinct functional components: a generation processing part that creates multiple candidate routes, a determination processing part that selects the appropriate route, and a storage part that records previous routes. This segmentation manages system complexity by organizing the route determination functionality into modular, manageable segments that work together to prevent soil damage.
