Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional plant application devices are used to apply pesticide, then the pesticide application process is simple and quick, but residual pesticide remains in the tank causing environmental contamination and waste
Solution Approach 1:
The invention extracts and removes residual pesticide from the tank using a suction device with nozzles positioned below the tank. The suction device actively draws out remaining pesticide through collection channels and filters, separating it from the tank environment to prevent contamination while maintaining efficient application operations
Solution Approach 2:
The system implements feedback through sensors that detect residual pesticide levels in the tank and automatically control the suction device operation. When residual pesticide is detected, the system activates suction nozzles and collection mechanisms to remove the residue, then monitors until the tank is sufficiently emptied, creating a closed-loop control system that eliminates contamination without manual intervention
2Object-affected harmful factors
If the tank is completely emptied to eliminate residues, then environmental safety is improved, but additional time and complexity are required for the emptying process
Solution Approach 1:
The invention merges the suction device with the existing tank structure by integrating collection channels directly into the tank bottom and positioning suction nozzles within the tank interior. This combination eliminates the need for separate external emptying equipment, reducing overall system complexity while achieving complete residue removal for environmental safety
Solution Approach 2:
The system performs self-service through automatic sensor-controlled operation. Sensors detect residual pesticide and automatically activate suction mechanisms, control collection channels, and manage the emptying process without external intervention. The system monitors its own tank status and executes the complete emptying sequence autonomously, minimizing operational complexity while ensuring thorough residue elimination
3Ease of operation
If residual pesticide is not collected, then the device operation is simpler and faster, but pesticide is wasted and pollutes the environment
Solution Approach 1:
The system performs preliminary action by positioning collection channels and suction nozzles in advance within the tank structure, ready to capture residual pesticide immediately after application stops. The sensors are pre-positioned to detect residues, and the collection system is prepared to activate automatically, preventing waste before it can be discharged into the environment while requiring minimal operational input
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
The system effectively eliminates residual pesticides, ensuring environmental safety and optimizing pesticide use by accurately determining and applying the required amount, thus preventing waste and ensuring complete tank emptying.
Implementation Method 1
The frame (1) comprises a pressure source (15), a tank (16), and a computer (17)... The computer (17) regulates the amount of plant protection product applied to the plants... The pesticide is applied by pressure or airflow
Implementation Method 2
Any pesticide residue that cannot be applied to the plant rows is drawn across a collection wall on the other side of the respective plant row and into a collection container... this collection wall is referred to as a suction bar with suction nozzles attached to it. The suction nozzles serve to capture any residual pesticide by suction
Implementation Method 3
The computer (17) uses an application sensor to detect the amount of pesticide applied
Implementation Method 4
It also uses a residual pesticide sensor to detect the amount of pesticide residue that cannot be applied

AI summary
The invention relates to a method for operating a plant application device (P) with a frame (1), wherein the frame (1) comprises a pressure source (15), a tank (16) and a computer (17) and applies a plant protection product from a first side onto a row of plants (10, 11) via a spreading nozzle (4, 4.1, 4.2, 4.3, 5, 5.1, 5.2, 5.3) of a spreading bar (2, 3) and draws in residual plant protection product via a suction nozzle (6, 6.1, 6.2, 6.3, 7, 7.1, 7.2, 7.3) of a suction bar (8, 9), and performs the following steps: - the computer (17) detects the plant protection product via a spreading sensor (18, 19); - the computer (17) detects the residual pesticide via a residual detection sensor (20, 21) - the computer (17) controls the pressure source (15) and a media application from the tank (16) to the application nozzle (4) so that the residual pesticide quantity approaches zero.
