Solution Overview

Problem

Existing agricultural fluid application systems face challenges in accurately monitoring and adjusting fluid distribution due to issues such as nozzle plugging, pressure variations, and spray pattern uniformity, which affect the efficiency and precision of applications like fertilizers, herbicides, and pesticides.

Innovation Solution

A system incorporating cameras and lights on a boom arm of a sprayer to capture images of spray patterns, analyze them using artificial intelligence, and adjust nozzle operation based on real-time feedback to ensure uniform distribution and identify blockages or drift.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional fluid application systems are used without real-time monitoring, then the system complexity is low, but the manufacturing precision and application uniformity deteriorate due to nozzle plugging and pressure variations

Engineering Contradiction:
Improvespray pattern uniformityVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary detection of spray patterns using cameras before fluid application issues become problematic. Image capture and AI analysis occur continuously in real-time, allowing the system to predict and prevent nozzle plugging and pressure variations before they significantly degrade spray uniformity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements a closed-loop feedback system where cameras capture spray patterns, AI algorithms analyze the images to detect deviations, and the system responds by adjusting nozzle operations or alerting operators. This real-time feedback continuously corrects spray pattern uniformity, maintaining high manufacturing precision despite system complexity.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If real-time monitoring and AI analysis are implemented, then the measurement precision of spray patterns improves, but the use of energy and device complexity increase

Engineering Contradiction:
Improvespray pattern detection accuracyVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent replaces traditional mechanical spray pattern analysis methods with optical imaging and AI-based digital analysis. Cameras capture spray patterns non-contactly, and machine learning algorithms process the images to detect patterns, blockages, and drift with high precision. This substitution reduces energy consumption compared to mechanical measurement devices while improving measurement accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates optical copies (images) of the spray patterns using cameras instead of direct physical measurement. These digital copies are then analyzed by AI algorithms to determine spray characteristics, blockages, and drift. This copying approach enables high-precision measurement with lower energy consumption than traditional mechanical sensors.

Inventive Principle:
Principle #26Copying

3Area of stationary object

If multiple cameras and lights are added to the boom arm, then the measurement precision and coverage area improve, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvemonitoring coverage areaVSAvoidnumber of components
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent designs the camera and light system on the boom arm to serve multiple functions: capturing spray patterns for analysis, detecting nozzle blockages, identifying drift, and monitoring overall application uniformity. By making the imaging system multi-functional, the patent achieves comprehensive coverage area without proportionally increasing device complexity, as the same hardware infrastructure supports multiple detection objectives.

Inventive Principle:
Principle #6Universality (Multi-functionality)
