Dual Blade Parallel Garden Hoe with Adjustable Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garden hoes are inefficient for creating multiple parallel rows simultaneously, requiring manual alignment and additional tools, leading to increased time and effort in gardening or farming.
Innovation Solution
A handheld dual-headed garden hoe with aligned blades on a shaft, allowing for simultaneous tilling of multiple parallel rows with adjustable blade spacing and loose attachment to prevent rust and improve shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single blade garden hoe is used, then the device is simple to operate, but it can only work the soil in a single direction requiring movement around plants
Solution Approach 1:
The garden hoe is divided into multiple independent blade segments (first blade and second blade) that are offset from each other, allowing each blade to work different rows of plants independently. This segmentation enables the user to till multiple directions without moving around the plants, improving productivity while maintaining ease of operation.
Solution Approach 2:
The blades are arranged in an offset configuration rather than being aligned in a single plane, adding a dimensional aspect to the blade arrangement. This offset positioning allows the blades to cover different angular directions, enabling multi-directional tilling from a single stationary position.
2Manufacturing precision
If multiple rows are tilled one at a time, then alignment can be achieved, but it requires additional tools and increased time
Solution Approach 1:
The device incorporates multiple blades (first blade and second blade) that are pre-aligned at fixed offsets, allowing simultaneous creation of multiple parallel rows in a single pass. This eliminates the need for sequential row creation and removes the requirement for additional alignment tools like stakes and string.
Solution Approach 2:
Multiple row-creating functions are merged into a single tool by attaching multiple blades to one handle. This combination allows the user to create multiple aligned rows simultaneously, integrating the alignment function that previously required separate tools into the main hoeing operation.
3Stability of the object's composition
If rigid blade attachment is used, then structural stability is improved, but shock is transmitted to the user and rusting occurs
Solution Approach 1:
The blade attachments are designed to be movable rather than rigidly fixed. The first blade and second blade can move independently within their mounting positions, allowing the structure to dynamically absorb shocks from hitting rocks or roots while maintaining operational stability during normal use.
Solution Approach 2:
The loose attachment mechanism provides inherent shock absorption capability before shocks are transmitted to the user. The ability of blades to move slightly in their mounts cushions impact forces, preventing direct transmission of shocks to the user's hands and arms.

AI summary
The dual blade garden hoe device includes an elongated handle having a shaft mounted at the working end thereof. A pair of blades is secured onto the shaft and disposed at a variable pitch. The blades can be positioned at various locations along the length of the shaft to create different widths between the blades. The blades comprise a cutting portion that create a pair of parallel troughs when dragged through soil. When the blades are in contact with the ground, each blade creates a separate and parallel trough, thereby reducing the time and effort needed to make a systematic gardens design or a plurality of farming rows. Additionally, the blades can move in a back and forth motion, depending upon the direction of travel, and laterally depending on obstructions in the soil.
