Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural working machines have limited flexibility in adjusting the interval of automatic traveling lines, which restricts their adaptability to varying working situations.
Innovation Solution
A working vehicle equipped with a reference registration controller, traveling line setter, and automatic steering controller that allows for the registration and adjustment of traveling reference lines, enabling the change of adjacency width between scheduled traveling lines based on user input or calculated work counts, facilitating adaptive automatic steering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the adjacency width between scheduled traveling lines is fixed at a constant interval, then the automatic traveling system is simple to operate, but the system lacks adaptability to varying working situations
Solution Approach 1:
The system transitions from fixed constant intervals to dynamically adjustable adjacency widths. The traveling line setter allows real-time modification of the interval between scheduled traveling lines based on actual working conditions, enabling the system to adapt flexibly to different agricultural tasks while maintaining operational simplicity through automated control.
Solution Approach 2:
The invention changes the parameter of adjacency width from a fixed constant value to a variable parameter that can be adjusted according to working requirements. By allowing the interval between traveling lines to be modified dynamically, the system achieves versatility in handling different crop rows, field conditions, and working scenarios without increasing operational complexity.
2Adaptability or versatility
If the adjacency width is changed frequently to adapt to different working conditions, then the versatility is improved, but the operation complexity increases
Solution Approach 1:
The system implements self-service functionality where the traveling line configuration automatically adapts to working conditions. The controller manages the complexity of adjusting multiple traveling line parameters, while the operator simply needs to input basic working information. The system then autonomously calculates and sets the appropriate adjacency widths, maintaining ease of operation while achieving high versatility.
3Ease of operation
If the traveling reference line is set before automatic steering, then the automatic traveling can be easily started, but the system cannot accommodate changes in working requirements during operation
Solution Approach 1:
The system maintains the simplicity of pre-setting the traveling reference line for easy startup, while simultaneously enabling dynamic adjustments to the scheduled traveling lines during operation. The traveling line setter allows modification of line intervals and positions based on actual working conditions, creating a hybrid system that combines ease of initiation with operational flexibility.
