Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural spreaders face challenges in accurately determining and setting optimal parameters for distribution discs, leading to inefficiencies and errors due to manual input and increased costs associated with transponder-based solutions.
Innovation Solution
The method utilizes sensors to detect the discharge characteristics of the spreading material, allowing for automatic determination of distribution disc information, eliminating the need for manual input and transponder systems, and enabling automatic adjustment of settings like disc speed and throwing angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual input of spreading disc information is used, then the system is simple and low-cost, but input errors occur and information accuracy deteriorates
Solution Approach 1:
The agricultural spreading device automatically detects and identifies spreading disc information through sensors that read identifiers on the discs themselves, eliminating the need for manual input by operators. The system serves itself by autonomously acquiring disc type, serial number, and other relevant information directly from the attached discs.
Solution Approach 2:
The patent replaces manual mechanical input methods with automated sensor-based detection systems. Optical sensors or RFID readers automatically capture disc information, substituting the manual writing or typing process with non-contact electronic detection that occurs automatically when discs are mounted.
2Extent of automation
If transponder-based detection is used, then information provision is automated, but costs and device complexity increase
Solution Approach 1:
The patent extracts only the essential identification features directly from the spreading disc surface or structure, such as visual identifiers, barcodes, or simple RFID tags integrated into the disc itself. This approach automates information provision while avoiding the complexity of full transponder systems by reading only necessary identification data.
Solution Approach 2:
The sensor system creates a digital copy or representation of the physical disc information by reading identifiers directly from the disc. This digital copy is then used by the control system to automatically adjust spreading parameters, eliminating the need for physical manual input while maintaining system simplicity.
3Extent of automation
If transponder-based detection is used, then information provision is automated, but costs increase
Solution Approach 1:
The patent employs simple, low-cost identification methods such as printed barcodes, color-coded identifiers, or basic RFID tags that can be easily manufactured and attached to spreading discs. These inexpensive identification elements are read by durable sensor systems, achieving automation without the high costs associated with complex transponder systems.

AI summary
Method for operating an agricultural spreader. The invention relates to a method for operating an agricultural spreader (10), comprising the step of: acquiring information on at least one rotatably driven distribution disc (18A, 18B) of the agricultural spreader (10) by a detection device (22) of the agricultural spreader (10), wherein the acquiring of information on the at least one rotatably driven distribution disc (18A, 18B) of the agricultural spreader (10) by the detection device (22) of the agricultural spreader (10) is based on at least one sensor signal which depends on the discharge characteristics of the spreading material.
