Solution Overview
Problem
Existing plant treatment systems fail to accurately treat critical weeds at early growth stages due to fixed thresholds, leading to untreated vegetation with high negative impact on yield and food safety.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed threshold is used for triggering treatment product application, then the treatment decision process is simple, but critical weeds at early growth stages may not be treated when vegetation density is low
Solution Approach 1:
The patent implements dynamic threshold adjustment by modifying the fixed threshold value based on real-time vegetative indicator measurements. The control system continuously adapts the treatment trigger threshold according to current vegetation density and composition, enabling reliable detection and treatment of critical weeds at all growth stages while maintaining a relatively simple control architecture.
Solution Approach 2:
The system changes the threshold parameter dynamically based on vegetative indicators such as vegetation density, species composition, and growth stage. By adjusting this key parameter in response to measured conditions, the system ensures that treatment decisions remain accurate across varying field conditions without requiring complex additional hardware.
2Object-affected harmful factors
If treatment is applied based on fixed thresholds, then the control system is simple to operate, but environmental impact increases due to unnecessary treatment application
Solution Approach 1:
The system incorporates feedback from vegetative indicator measurements to continuously adjust treatment decisions. By measuring actual vegetation conditions and feeding this information back to the control system, the patent enables precise treatment only when and where needed, reducing environmental impact while maintaining simple operation through automated decision-making.
Solution Approach 2:
The control system dynamically adjusts the treatment threshold parameter based on measured vegetative indicators, enabling it to distinguish between situations requiring treatment and those that do not. This parameter adaptation reduces unnecessary treatment application and its environmental impact while keeping the system easy to operate through automated adjustments.
3Measurement precision
If real-time image analysis is performed to detect vegetation, then treatment accuracy improves, but processing time and computational requirements increase
Solution Approach 1:
The patent extracts and focuses on specific key vegetative indicators (such as vegetation density, species type, and growth stage) from the full image data rather than processing all image information. This extraction of essential features maintains high detection accuracy while significantly reducing computational burden and processing time.
Solution Approach 2:
The system changes the processing approach by focusing on specific parameter extraction (vegetative indicators) rather than comprehensive image analysis. By identifying and measuring only the most relevant parameters for treatment decisions, the system achieves high measurement precision with reduced computational requirements and faster processing.
