Solution Overview

Problem

Existing agricultural tillage combinations require separate equipment for applying granular and liquid fertilizers, necessitating frequent changes when switching between the two, which is inefficient and time-consuming.

Innovation Solution

A modular design for the fertilizer storage container and dosing device that allows for quick conversion between granular and liquid fertilizer applications, using interchangeable metering devices and quick-change fastening systems, along with a pressure-tight reservoir for uniform liquid fertilizer distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If separate equipment is used for granular and liquid fertilizers, then dosing precision is improved, but device complexity and switching time increase

Engineering Contradiction:
Improvedosing precisionVSAvoidequipment configuration
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The storage container is designed with a universal interface that can accommodate both granular and liquid fertilizer dosing devices. The container includes a closure piece with a standardized connection interface that accepts different types of dosing devices through quick-change coupling mechanisms, allowing one storage container to serve multiple functions for different fertilizer types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The dosing system is segmented into separate, interchangeable components: the storage container, the closure piece, and the dosing device. This segmentation allows the dosing device to be detached and replaced independently while the storage container remains, enabling quick switching between granular and liquid fertilizer configurations without replacing the entire system.

Inventive Principle:
Principle #1Segmentation

2Reliability

If dedicated storage containers are used for each fertilizer type, then dosing reliability is improved, but loss of time during conversion increases

Engineering Contradiction:
Improvedosing reliabilityVSAvoidconversion time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The storage container is pre-equipped with a standardized closure piece that has ready-made connection interfaces for different dosing devices. Quick-change coupling mechanisms are pre-installed on the closure piece, allowing dosing devices to be rapidly attached or detached without requiring complex assembly or disassembly procedures, thus maintaining reliability while minimizing conversion time.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If interchangeable dosing devices are implemented, then adaptability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvefertilizer type flexibilityVSAvoiddevice assembly
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The closure piece is manufactured as a universal component with standardized connection features that can interface with multiple types of dosing devices. This universal design allows the same closure piece to work with both granular and liquid fertilizer dosing devices, simplifying manufacturing by producing a single versatile component rather than multiple specialized ones.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Productivity

If quick-change devices are used for dosing device replacement, then productivity is improved, but device complexity increases

Engineering Contradiction:
Improveswitching speedVSAvoidquick-change mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The quick-change mechanism is segmented into simple, standardized coupling features on the closure piece that match corresponding interfaces on the dosing devices. This segmentation creates a straightforward connect-and-disconnect system using basic mechanical coupling elements, achieving rapid switching without requiring complex mechanisms.

Inventive Principle:
Principle #1Segmentation

AI summary

The dispensing system that can be used for both seed and manure in an agricultural process uses exchangeable tanks [1] with a fast action connector [2] for fitting [3] to the dispenser. This has a feed blower [6] with a hose connection [5] to a number of dispensing nozzle lines [8].
