Hoeing Share Geometry for Soil Loosening Over Stones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoe shares are limited in their ability to efficiently loosen soil and manage obstacles like stones during mechanical weed control, often requiring chemical herbicides for effective weed management.
Innovation Solution
A hoeing blade design featuring a mounting section, transition section, primary and secondary tillage sections, and a forward projection for breaking up soil, allowing for efficient soil loosening and obstacle navigation while minimizing mechanical resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hoe shares are pressed through the soil during use, then soil loosening is achieved, but mechanical resistance increases when obstacles like stones are encountered
Solution Approach 1:
The patent inverts the conventional pushing action by implementing a pulling action. The share is designed to be pulled through the soil rather than pushed, which allows it to navigate over obstacles like stones without encountering high mechanical resistance, while still achieving effective soil loosening through the pulling force
2Productivity
If chemical herbicides are used for weed control, then effective weed management is achieved, but environmental harm and chemical dependency increase
Solution Approach 1:
The patent replaces chemical herbicides with a mechanical weed control system. The specially designed share with its unique geometry and pulling action mechanically cuts and uproots weeds through soil cultivation, providing effective weed control without relying on chemical substances
3Device complexity
If the hoe blade has a simple single-section design, then device complexity is reduced, but soil cultivation effectiveness decreases
Solution Approach 1:
The patent divides the hoe blade into multiple functional sections: a mounting section for attachment, a transition section for force distribution, and a tillage section for soil cultivation. This segmentation allows each part to perform its specific function optimally, enhancing overall soil cultivation effectiveness while maintaining a relatively simple integrated structure
