Digging Fork With Angled Tines for Breaking Soil Clumps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digging tools struggle to effectively break up hard clumps of soil, which can hinder root growth for plants, as they often impale rather than break the clumps, making soil preparation inefficient.
Innovation Solution
A digging fork with angled second and third tines forming a wedge shape and connected by bars, allowing the tines to converge and form a single point, enabling the tool to break clumps of soil by tapering outward from the distal ends towards the shaft, thereby facilitating easier soil preparation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional digging tools with parallel tines are used, then the structure is simple and easy to manufacture, but the tool cannot effectively break up hard clumps of soil as it only impales them
Solution Approach 1:
The patent applies asymmetry by configuring the second and third tines at angles to each other, forming a wedge shape, while the first and fourth tines remain substantially parallel. This asymmetric arrangement allows the angled tines to converge and form a single point that effectively breaks hard soil clumps, while the parallel tines maintain structural simplicity and ease of manufacture.
2Ease of manufacture
If the tines are made parallel and evenly spaced, then the manufacturing is easier, but the tool lacks the wedge shape needed to break hardened soil
Solution Approach 1:
The patent applies local quality by making only the second and third tines angled to form a wedge shape, while keeping the first and fourth tines substantially parallel. This localized angular configuration provides the necessary wedge shape for breaking hardened soil clumps, while maintaining uniform and easy manufacturing for the majority of the tine structure.
3Productivity
If the tines converge to a single point, then the tool can effectively break soil clumps, but the structural complexity increases due to connecting bars
Solution Approach 1:
The patent applies segmentation by dividing the tine structure into distinct sections connected by bars. The bars connect adjacent tines at specific positions, creating a segmented framework that supports the convergent wedge shape of the second and third tines while maintaining structural integrity with minimal additional components.

Function Achieved in This Case
The fork efficiently breaks up clumps of soil, allowing for easier digging in claggy conditions compared to conventional tools, enhancing soil preparation for planting by effectively penetrating and breaking hardened soil without impaling it.
Implementation Method 1
the second and third tines are angled towards each other to form a wedge shape; the pair of tines tapering outwardly from the distal point or distal ends towards the shaft of the fork

AI summary
A digging fork has a shaft at an end of which extends in a row first, second, third and fourth tines. The second and third tines are angled towards each other to form a wedge shape and the first and fourth tines are substantially parallel to each other.
