Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route planning systems for agricultural machines require computing-intensive algorithms to determine the working width of a plow, leading to frequent plow release and inefficiency, especially in complex field geometries.
Innovation Solution
A method that divides the field into sections with straight boundaries, calculates the distance between the plow position and section boundaries using a central point, and adjusts the working width based on this distance, allowing for efficient field cultivation with minimal computational effort.

Engineering Contradiction Analysis
1Manufacturing precision
If computationally intensive algorithms are used to determine the route and working width, then the route can be optimized based on complex field geometries, but the plow frequently starts and stops leading to reduced productivity
Solution Approach 1:
The field is divided into multiple sections with straight boundaries, and the working width is calculated separately for each section based on simple geometric relationships. This segmentation allows the use of simple calculations instead of complex global optimization algorithms, maintaining route optimization while enabling continuous plow operation.
Solution Approach 2:
The approach changes from using complex computational parameters (global route optimization algorithms) to simple geometric parameters (section boundaries, central points, and distances). This parameter transformation enables real-time calculation of working width without frequent interruptions to plow operation.
2Manufacturing precision
If complex algorithms are used to calculate working width in complex field geometries, then accurate furrow placement can be achieved, but computational effort increases significantly
Solution Approach 1:
The field is segmented into sections with straight boundaries, allowing the use of simple geometric calculations (distance from central point along circular arc) instead of complex algorithms. This maintains furrow placement accuracy while dramatically reducing computational requirements.
Solution Approach 2:
The patent uses simple, easily calculable geometric parameters (section boundaries, central points, arc distances) that can be computed quickly and discarded, replacing complex computational models. This enables real-time working width adjustment with minimal computational resources.
3Manufacturing precision
If the plow working width is frequently adjusted based on complex calculations, then the field can be cultivated evenly, but the plow operation becomes interrupted and inefficient
Solution Approach 1:
The calculation method changes from complex global optimization to simple geometric parameters (distance from central point along circular arc). This enables continuous plow operation with real-time working width adjustment, maintaining furrow uniformity without operational interruptions.
Solution Approach 2:
The patent enables continuous plow operation by using simple geometric calculations that can be performed in real-time without interrupting the plowing process. The working width is continuously adjusted based on the plow's position relative to section boundaries, maintaining furrow uniformity while avoiding frequent starts and stops.
