Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural vehicles face challenges in efficiently navigating and straightening paths during operations like planting and harvesting, as existing systems struggle to minimize non-covered areas and deviations from straight lines, leading to inefficiencies and increased operational costs.
Innovation Solution
A system comprising a processor and GNSS unit that generates guidance paths using algorithms like the least square method, allowing for user-defined thresholds and machine learning adjustments, to command an automatic steering system for agricultural vehicles, ensuring subsequent passes are straight and minimize crowding and non-covered areas.

Engineering Contradiction Analysis
1Ease of operation
If existing guidance systems use fixed straight-line paths, then navigation simplicity is improved, but non-covered areas and deviations increase leading to operational inefficiency
Solution Approach 1:
The guidance system dynamically adjusts path geometry based on actual field conditions and vehicle position. Instead of fixed straight-line paths, the system generates adaptive guidance paths that correct deviations iteratively, allowing the path to evolve from initial non-straight trajectories to optimized straight-line coverage while minimizing non-covered areas.
Solution Approach 2:
The system implements feedback mechanisms where vehicle position data from GNSS receivers is continuously processed to calculate deviations from desired paths. This feedback drives iterative corrections to guidance paths, adjusting subsequent passes to compensate for previous deviations and crowding, thereby improving both navigation simplicity and operational efficiency.
2Manufacturing precision
If guidance paths are adjusted to minimize non-covered areas, then coverage completeness is improved, but path deviation from straight lines increases
Solution Approach 1:
The field coverage problem is segmented into multiple iterative passes, where each pass corrects a portion of the total deviation. Rather than attempting to minimize all non-covered areas in a single straight path, the system divides the correction into sequential segments, with each pass addressing specific deviation patterns while maintaining overall straightness.
Solution Approach 2:
The system applies partial corrections to guidance paths on each pass, adjusting only the necessary portions to minimize non-covered areas without over-correcting and creating excessive deviations. This controlled partial action allows progressive improvement of coverage completeness while maintaining acceptable path straightness.
3Shape
If iterative path correction is applied to straighten subsequent passes, then path straightness is improved, but system complexity increases
Solution Approach 1:
The system replaces complex mechanical path adjustment mechanisms with computational algorithms. Instead of physical devices to mechanically straighten paths, the invention uses software-based iterative correction algorithms that process GNSS data and generate adjusted guidance paths, significantly reducing mechanical complexity while achieving path straightness.
Solution Approach 2:
The iterative correction system changes key parameters such as path offset distances, correction angles, and spacing between passes to optimize straightness. By systematically adjusting these parameters across multiple passes, the system achieves path straightness through parameter optimization rather than complex mechanical interventions.
