Modular Harrow Tine Attachment for Variable Soil Cultivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional harrows have narrow, widely spaced tines that limit soil cultivation efficiency and require separate devices for different soils and applications, leading to high costs.
Innovation Solution
A modular attachment system for harrow tines that allows adjustable diameter and depth, using a sleeve and widening element made of steel, enabling variable effective range and depth penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional narrow tines are used, then the device structure is simple, but the soil cultivation efficiency is limited and coverage area is small
Solution Approach 1:
The tine is divided into modular components: a base tine and an attachable widening element. This segmentation allows the widening element to be detached or attached as needed, increasing soil coverage area when required while maintaining the simple base structure for other applications, thus resolving the contradiction between productivity and device complexity.
Solution Approach 2:
The tine configuration is made dynamic and adjustable through the attachable widening element. Users can adapt the tine width according to specific soil conditions and cultivation requirements, enabling the same device to achieve high productivity across diverse applications without requiring multiple fixed-configuration devices.
2Adaptability or versatility
If tines with fixed diameter are used, then the device is simple to manufacture, but it is not suitable for all cultivation soils and applications
Solution Approach 1:
The base tine is designed as a universal component that can accommodate different widening elements for various soil types and applications. The standardized interface allows one base tine to serve multiple functions by simply changing the attachment, achieving versatility without requiring complex manufacturing of multiple specialized tines.
Solution Approach 2:
The tine diameter parameter can be changed by attaching different widening elements with varying dimensions. This allows the same base tine to be adapted to different soil conditions (e.g., narrow for grain fields, wider for other soils) without manufacturing complexity, as only the attachment parameter changes.
3Adaptability or versatility
If separate processing devices are used for different soils, then each device is optimized for its specific application, but the overall cost increases
Solution Approach 1:
Instead of requiring multiple separate processing devices for different soils, the invention provides a universal base tine that can be equipped with different widening elements. This single versatile device replaces multiple specialized devices, reducing the quantity of equipment needed while maintaining application-specific optimization through interchangeable attachments.
