Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing landscaping devices fail to efficiently create and maintain uniform, concentric circles around trees, leading to inconsistent and non-concentric tree wells when using trimming tools.
Innovation Solution
A landscape trimming tool attachment device with a telescoping extension shaft, curved collar, and attachment portion, featuring detents and notches for secure connection, diameter markers, and a hand grip, allowing for adjustable extension and secure attachment of trimming tools to create uniform tree wells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a freehand method is used to walk around the tree while trimming, then the operator can trim the tree well, but the resulting circles are non-concentric and inconsistent in diameter
Solution Approach 1:
The patent introduces a guiding device as an intermediary between the operator and the trimming tool. This device includes a curved collar that fits around the tree and a telescoping extension shaft with a guide arm that extends outward to define the trimming path. The guide arm acts as a physical mediator that constrains the trimming tool to maintain a constant distance from the tree trunk, ensuring concentric circles while allowing the operator to simply follow the guide arm during operation.
Solution Approach 2:
The guiding device is segmented into multiple functional components: a curved collar section that contacts the tree, a telescoping extension shaft that provides adjustable length, and a guide arm that defines the trimming radius. This segmentation allows each component to perform its specific function independently while working together as a unified system to solve the concentricity problem.
2Object-affected harmful factors
If guard-style devices are used to prevent damage to the tree, then the tree is protected from trimming tool contact, but the trimming tool cannot be extended sufficiently away from the tree to create uniform concentric circles
Solution Approach 1:
The patent employs a telescoping extension shaft that can dynamically adjust its length during operation. The shaft includes nested tubular sections that can slide relative to each other, allowing the guide arm to extend to various distances from the tree trunk. This dynamic adjustment capability enables the operator to select the appropriate trimming radius while maintaining protection against tree damage, as the collar prevents the tool from getting too close regardless of the extension length.
3Manufacturing precision
If a fixed-length extension device is used, then the trimming tool can be positioned at a consistent distance from the tree, but the device cannot be adjusted for different tree sizes or desired tree well diameters
Solution Approach 1:
The telescoping extension shaft provides dynamic adjustability through nested tubular sections that can be extended or retracted to achieve different lengths. This allows the device to adapt to various tree trunk diameters and desired tree well sizes while maintaining precise control over the trimming distance once set. The collar can be positioned at different heights on the tree trunk, and the extension shaft can be adjusted to different lengths, providing versatility for different applications.
Solution Approach 2:
The device allows changes in key parameters: the extension length of the shaft and the height position of the collar on the tree trunk. By adjusting these parameters, the operator can accommodate different tree sizes and create tree wells of various diameters. The telescoping mechanism enables continuous or discrete adjustment of the trimming radius, making the device adaptable to diverse landscaping requirements.
