Garden Multitool Swing Head With Interchangeable Working Attachments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swing shovels are limited to ground-level tasks and lack versatility for use as garden tools, failing to meet user demands for a variety of gardening functions.
Innovation Solution
A garden multitool equipped with a shaft and handle assembly, allowing a back-and-forth swing tool to be used for gardening tasks, featuring interchangeable heads such as a saw blade, steel wire head, and shovel blade, with a high swing frequency and adjustable angle for enhanced versatility and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a swing shovel is designed for ground-level tasks only, then the structure can be simplified, but the versatility and functional utilities are limited
Solution Approach 1:
The patent applies universality by enabling the swing shovel to perform multiple functions through interchangeable working heads. The device can switch between ground-level tasks (using shovel blade) and gardening tasks (using saw blade or steel wire head), transforming a single-function tool into a multi-functional garden multitool that satisfies diverse user demands
2Productivity
If a speed reduction structure is added to the swing working assembly, then the swinging frequency can be reduced for better control, but the weight of the working head increases and operating efficiency decreases
Solution Approach 1:
The patent applies the extraction principle by removing the speed reduction structure from the swing working assembly. This eliminates unnecessary mechanical components that would increase weight and reduce operating efficiency, while the electric motor directly drives the working head to achieve high-frequency swinging motion for improved productivity
3Productivity
If the back-and-forth swing angle is increased, then the cutting depth or removal efficiency may improve, but the tool becomes difficult to operate in narrow spaces
Solution Approach 1:
The patent applies dynamics by implementing an adjustable swing angle mechanism that allows the working head to adapt its swinging range based on operational requirements. The swing angle can be adjusted between different positions, enabling the tool to achieve effective cutting depth in open spaces while maintaining compact operation in narrow spaces, thus improving both productivity and ease of operation

AI summary
A garden multitool, which relates to a power tool, including a working assembly, the working assembly having an electric motor and a working head, the electric motor actuating the working head to swing back and forth on a working plane; the garden multitool further includes a shaft and a handle assembly, the working assembly being attached to a front end of the shaft, the handle assembly being attached to a rear end of the shaft, a lengthwise direction of the shaft being parallel to the working plane. By appropriately improving the structure of the garden multitool, the functional utilities of the swing power tool are reasonably extended, which helps to enhance user experience.
