Camera-Guided Sprayer Boom Control for Uniform Nozzle Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural fluid application systems lack precise control over fluid distribution, leading to inefficiencies and inconsistencies in spray patterns due to factors like nozzle clogging and varying flow rates.
Innovation Solution
The implementation of cameras and lights on a boom arm of a sprayer, coupled with a network and processing system, allows for real-time monitoring and adjustment of nozzle operation, enabling precise control over fluid application by analyzing spray patterns and nozzle performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS-based guidance systems are used to improve steering accuracy, then field burn reduction is improved, but system cost and complexity increase
Solution Approach 1:
The patent replaces complex GPS-based electronic guidance systems with a simple mechanical implement trailering system that uses physical drag and alignment forces to guide the implement behind the tractor, eliminating the need for satellites, receivers, and complex control electronics while maintaining acceptable steering accuracy
Solution Approach 2:
The implement trailering system is self-aligning through mechanical forces - the implement naturally trails behind the tractor following the tractor's path without requiring active control systems, sensors, or power consumption, as the drag and tension forces automatically maintain proper positioning
2Productivity
If implement trailering systems are used to reduce field burn, then productivity is improved, but control precision deteriorates
Solution Approach 1:
The patent introduces a trailering connection as an intermediary mechanical element between the tractor and implement that transfers steering commands through physical forces, allowing the implement to follow the tractor's path with minimal intervention while maintaining simple steering control through the drag and alignment forces of the trailering system
