Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Reliability
If dedicated storage containers are used for each fertilizer type, then dosing reliability is improved, but loss of time during conversion increases
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.
3Adaptability or versatility
If interchangeable dosing devices are implemented, then adaptability is improved, but manufacturing complexity increases
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.
4Productivity
If quick-change devices are used for dosing device replacement, then productivity is improved, but device complexity increases
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.

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].
