Fabric Roller Pickup for Grass Burr Removal Without Hand Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of suitable devices for efficiently removing stickers like grass burrs or 'goat heads' from grassy and other areas without manually handling them, which can be painful and inconvenient.
Innovation Solution
A roller apparatus with a rotatably mounted stretchable fabric sleeve made of suitable materials like polyester, acrylic, or burlap is used to pick up stickers, allowing them to be easily collected and disposed of without direct handling, with the sleeve being removable and replaceable when full.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If stickers are picked up by hand individually or in raked up bunches, then the task can be completed, but the process is painful and inconvenient due to direct handling of stickers
Solution Approach 1:
The patent introduces a fabric-covered roller as an intermediary tool between the user and the stickers. The fabric sleeve contacts and collects the stickers, allowing removal without direct hand contact. This mediator transfers the harmful interaction from the user's hands to the fabric surface, eliminating pain while maintaining effectiveness.
2Productivity
If no suitable device is used for removing stickers, then manual handling is required, but this lacks efficiency and reliability
Solution Approach 1:
The device segments the sticker removal function into distinct components: a roller mechanism for contact and movement, and a removable fabric sleeve for collection. This segmentation allows the fabric to be replaced when saturated, maintaining consistent performance and reliability while improving productivity through mechanized rolling action.
3Ease of operation
If a fabric sleeve is used to collect stickers, then direct handling is avoided, but the sleeve requires periodic removal and replacement
Solution Approach 1:
The fabric sleeve is designed to be dynamically replaceable rather than permanently fixed. This dynamic configuration allows the sleeve to be removed and replaced as needed, maintaining simplicity while enabling continuous operation. The removable design balances ease of operation with minimal complexity, avoiding permanent attachment systems.

AI summary
An apparatus and method for picking up stickers in grassy or other ground areas. A roller is rotatably mounted on a frame and a stretchable fabric is removably mounted and stretched on an outer surface of the roller. The fabric is of a construction and thickness to pick up stickers as the roller is moved by the frame and rotated in engagement with a grassy or other ground surface. When the fabric is full of stickers, it is removed from the roller and replaced with a new unused stretchable fabric that is removably mounted on the roller.
