Agricultural Spraying Device Cotyledon Weed Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural spraying methods apply plant protection agents uniformly across fields, failing to account for the specific cotyledon class of crop plants and weeds, which affects treatment effectiveness and increases the risk of phytotoxicity.
Innovation Solution
A method utilizing an agricultural spraying device equipped with a control unit and optical acquisition unit to identify the cotyledon class of crop plants and weeds, assigning weed identification numbers based on their class, and adjusting the application of spray products accordingly to optimize treatment effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If full-surface application of spray mixture is used, then complete field coverage is achieved, but plant protection agents are wasted in areas where they are not needed
Solution Approach 1:
The patent implements local quality by differentiating spray application based on local field conditions. The control unit activates individual nozzles or sections only in areas where weeds are detected, rather than applying spray uniformly across the entire field. This ensures that plant protection agents are applied only where needed, reducing waste while maintaining effective treatment coverage.
2Measurement precision
If site-specific application is used to reduce spray mixture usage, then treatment precision is improved, but the complexity of the spraying device increases
Solution Approach 1:
The patent introduces an intermediary sensor system that detects weed presence and communicates this information to the control unit. This intermediary layer enables precise treatment decisions without requiring complex direct control mechanisms, as the sensor acts as a mediator between the field conditions and the spray application system.
Solution Approach 2:
The spraying device is segmented into individually controllable nozzles or sections. Each nozzle or section can be independently activated or deactivated based on local weed detection, allowing precise treatment of specific areas without treating the entire field. This segmentation enables targeted application while maintaining system manageability.
3Ease of operation
If uniform treatment of all weeds is applied, then application process is simplified, but treatment effectiveness varies depending on weed species and crop type
Solution Approach 1:
The patent applies local quality by differentiating treatment strategies based on the specific combination of crop plant type and weed type detected. The control unit selects appropriate spray products and application parameters tailored to the identified weed-crop combination, ensuring optimal treatment effectiveness for each local condition rather than applying a uniform approach across the entire field.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enables a site-specific, effective application of spray products by tailoring the treatment strategy to the cotyledon class of both crop plants and weeds, improving treatment success and reducing phytotoxicity risks.
Implementation Method 1
acquiring a field section of the agricultural land by means of an optical acquisition unit of the agricultural spraying device in order to obtain image information

AI summary
A method for applying at least one spray product to agricultural land having crop plants and weeds. The crop plants and weeds can be assigned to a cotyledon class of monocotyledons or to a cotyledon class of dicotyledons. The at least one spray product is applied to the acquired field section of the agricultural land by means of at least one spray nozzle unit of an agricultural spraying device depending on the cotyledon class of the crop plants and a first ascertained weed identification number and/or a second ascertained weed identification number.
