Vegetation Removal Device With Segmented Tapered Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for removing vegetation from ground surfaces, such as yards and fields, are inefficient in capturing and collecting unwanted vegetation like weeds and flowers, as they lack effective mechanisms to securely grasp and remove vegetation without damaging the surrounding area.
Innovation Solution
A device with a body featuring multiple channels that narrow from an inlet to a pinch point, allowing vegetation to be captured and removed, utilizing a handle angled for ease of use and adjustable to accommodate different surfaces, and optionally integrable with conventional tools like rakes for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rakes or lawn tools are used to collect vegetation, then vegetation removal is possible, but the capture efficiency and security of grasping vegetation is insufficient
Solution Approach 1:
The body is divided into multiple channels, each capable of independently receiving and capturing vegetation. This segmentation allows simultaneous processing of multiple vegetation pieces, improving both capture reliability and overall productivity
Solution Approach 2:
Each channel has a specific pinch point location optimized for capturing vegetation of different sizes and types. The localized pinch points provide targeted grasping force where needed, enhancing capture efficiency without requiring uniform force across the entire device
2Reliability
If a simple rake structure is used, then the device is easy to manufacture, but it cannot securely grasp and remove vegetation without damaging surrounding areas
Solution Approach 1:
The body is segmented into multiple channels with defined inlet and pinch point regions. This segmentation provides structured vegetation guidance and capture paths, achieving secure grasping through geometric design rather than complex mechanical components
Solution Approach 2:
Instead of using active gripping mechanisms that move to grasp vegetation, the invention uses passive geometric convergence where channels naturally guide vegetation to pinch points. This inverted approach achieves secure grasping through shape rather than motion, simplifying manufacturing
3Reliability
If channels have uniform width, then manufacturing is simpler, but vegetation cannot be effectively pinched and captured
Solution Approach 1:
Each channel has non-uniform width with a specific pinch point location where the channel narrows. This local geometric variation creates effective vegetation capture zones while maintaining overall manufacturing simplicity through consistent channel patterns
Solution Approach 2:
The channel width parameter varies along the length of each channel, transitioning from wider inlet regions to narrower pinch point regions. This parameter change enables effective vegetation pinching and capture while the regular pattern of variation keeps manufacturing precision requirements manageable

AI summary
A device is provided for removing vegetation from ground surfaces. The device includes a body defining multiple channels, wherein each channel of the multiple channels has an inlet for receiving vegetation into the channel and a pinch point for capturing the vegetation in the channel. In connection therewith, a width dimension of each channel of the multiple channels at the inlet is greater than a width dimension of said channel at the pinch point.
