Multi-Blade Garden Transplanter with Mechanical Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held garden tools are limited in their ability to perform specific functions, such as digging into compacted soil, and are prone to breakage, especially at the juncture between the handle and the tool, due to their design limitations.
Innovation Solution
A multi-blade garden transplanter tool with a blade assembly featuring multiple blades arranged symmetrically around a center axis, including serrations, knife edges, and notches, combined with a handle secured to a tang made of higher durometer material for enhanced strength and ergonomic design, allowing for secure attachment and improved functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single flat trowel blade is used, then the tool can be inserted into compacted soil, but it cannot effectively loosen the soil without compromising tool integrity
Solution Approach 1:
The single flat trowel blade is segmented into multiple blades (at least three) extending outward along a center axis from the free end to the handle end. This segmentation allows the tool to effectively loosen compacted soil through the combined action of multiple blades while distributing mechanical stress, preventing tool failure.
Solution Approach 2:
The blade configuration transitions from a two-dimensional flat surface to a three-dimensional multi-blade structure extending radially outward. This dimensional change enables the tool to engage compacted soil more effectively from multiple angles simultaneously, improving soil loosening capability while maintaining structural integrity.
2Ease of operation
If known hand-held garden tools are used, then they can perform basic gardening tasks, but they are prone to breakage at the juncture between handle and implement
Solution Approach 1:
The tool employs composite material construction with a metal blade assembly and a handle made from plastic, rubber, or composite materials. This combination of materials optimizes both functionality and durability, reducing breakage at the handle-implement junction while maintaining effective gardening performance.
Solution Approach 2:
The blade assembly is nested within or securely attached to the handle structure, with the tang extending from the implement and being secured to the handle. This nested configuration strengthens the connection point and distributes mechanical loads, preventing breakage at the critical junction between handle and implement.
3Adaptability or versatility
If a hand-held shovel is used, then it can dig into loose soil, but it is not well-suited for digging into or loosening compacted soil
Solution Approach 1:
The multi-blade garden transplanter tool combines features of multiple traditional tools into a single implement. The blade assembly with at least three blades extending radially provides both the penetration capability of a shovel and the loosening ability of a cultivator, making it adaptable to various soil types including compacted soil while maintaining ease of operation.

AI summary
The present invention is directed to a hand tool that includes an implement, a tang extending from the implement, and a handle secured tot the tang. The handle includes an opposing surface facing away from the implement, and a portion of the tang is configured to engage a portion of the opposing surface to mechanically lock the handle and tang together. The present invention is also directed to a multi-blade garden transplanter tool that includes at least three blades extending outward along a center axis from a free end to a handle end, and a handle is secured to the handle end.
