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

VSEngineering 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

Engineering Contradiction:
Improveinformation accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

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.

Inventive Principle:
Principle #25Self-service

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.

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

2Extent of automation

If transponder-based detection is used, then information provision is automated, but costs and device complexity increase

Engineering Contradiction:
Improveautomation levelVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #26Copying

3Extent of automation

If transponder-based detection is used, then information provision is automated, but costs increase

Engineering Contradiction:
Improveautomation levelVSAvoidcost
Core Design Contradiction:
Extent of automationVSQuantity of substance

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.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
