Garden Tool Attachment Lift Locking for Quick Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Garden tools often have limited functionality due to single-use modules, reducing their utilization rate, especially when attachments like snow throwers need to adjust their position for effective operation.
Innovation Solution
An adjusting device with a lifting device and locking mechanism allows quick and convenient adjustment of an attachment's position between a first and second position, using a pedal assembly, connecting portions, and a locking mechanism to facilitate seamless transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a garden tool has only a single function module, then the structure is simple, but the utilization rate is reduced due to seasonal limitations
Solution Approach 1:
The garden tool is designed with a universal interface that allows different attachments (lawn mower, snow thrower, etc.) to be connected to the same driving body, enabling the tool to perform multiple functions across different seasons and conditions
2Ease of operation
If the attachment position is fixed, then the structure is simple, but the use effect is reduced when obstacles need to be overcome
Solution Approach 1:
The attachment is designed to be dynamically adjustable in position, allowing it to be lowered close to the ground for effective gardening work and lifted high to overcome obstacles, with a locking mechanism to maintain the desired position
3Productivity
If the attachment position adjustment is manual and complex, then the device complexity is low, but the adjustment time is excessive
Solution Approach 1:
The adjusting device incorporates a self-locking mechanism that automatically maintains the attachment position without requiring continuous manual effort, allowing quick adjustment and automatic positioning
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the practicality of garden tools by enabling them to perform multiple tasks across seasons, reducing maintenance and increasing usability through efficient attachment positioning.
Implementation Method 1
a locking mechanism including: a fixing portion connected to the garden tool; and a locking portion, rotatably connected with the fixing portion; wherein the locking portion is engaging with the lifting device when the attachment is in the first position
Implementation Method 2
the lifting device comprises a pedal assembly rotatably connected to the attachment, and a connecting portion connected to the pedal portion and the attachment

AI summary
An adjusting device includes a lifting device for adjusting a position of an attachment in use and a locking mechanism. The lifting device is switched between a locking position and a free position under a locking action of the locking mechanism, the lifting device drives the attachment to move to a first position when the lifting device is in the locking position; and the lifting device drives the attachment to move to a second position so as to work when the lifting device is in the free position. The adjusting device has a simple structure, a low production cost, an easy maintenance, and a garden tool using the adjusting device can conveniently and quickly adjust the position of the attachment connected to the garden tool.
