Neoprene Goathead Roller With Adjustable Scraper Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods are inadequate for effectively collecting and removing goathead seed pods from the ground, which can cause punctures and damage to lawns and surfaces.
Innovation Solution
A metal roller with a neoprene-covered drum and adjustable scraper bar, equipped with a catch basin, designed to collect and remove goathead seed pods as it is rolled over the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a roller is used to collect goathead seed pods, then collection efficiency is improved, but the roller may damage lawns and surfaces due to the weight and pressure of the device
Solution Approach 1:
The device divides the collection function into two separate components: a neoprene-covered drum for picking up seed pods and an adjustable scraper bar for removing them. This segmentation allows each component to be optimized independently - the drum can be lightweight for lawn safety while the scraper handles the removal task, resolving the contradiction between collection efficiency and surface damage prevention.
Solution Approach 2:
The scraper bar is made adjustable in position relative to the drum, allowing the user to dynamically change the scraping distance based on the size of seed pods and ground conditions. This dynamic adjustment enables the system to maintain effective collection while adapting to different surface types, preventing damage to lawns and surfaces while preserving collection efficiency.
2Productivity
If the scraper bar is positioned close to the drum for effective scraping, then seed pod removal efficiency is improved, but the risk of fabric snagging and damage increases
Solution Approach 1:
The scraper bar position is made adjustable via bolts and wing nuts, allowing users to dynamically optimize the distance between the scraper and drum based on seed pod size and ground conditions. This dynamic positioning enables effective scraping while maintaining a safety margin to prevent fabric snagging, resolving the contradiction between removal efficiency and fabric durability.
Solution Approach 2:
The system allows changing the operational parameter (scraper-to-drum distance) based on conditions. By adjusting this parameter, users can achieve effective seed pod removal for large pods while using a larger clearance for smaller pods or delicate surfaces, thereby preventing fabric damage while maintaining removal efficiency.
3Object-affected harmful factors
If the roller is designed to be lightweight for lawn safety, then damage prevention is improved, but the effectiveness of scraping seed pods from the ground decreases
Solution Approach 1:
The device separates the weight-bearing function from the scraping function. The neoprene-covered drum remains lightweight for lawn safety, while the adjustable scraper bar provides the mechanical leverage needed for effective seed pod removal. This segmentation allows the lightweight structure to prevent damage while the scraper component delivers scraping effectiveness.
Solution Approach 2:
The adjustable scraper bar acts as an intermediary mechanical element that transfers the user's pushing force efficiently to the seed pods. This intermediary component provides the necessary scraping power without requiring the entire roller structure to be heavy, thus maintaining lawn safety while achieving scraping effectiveness.

Function Achieved in This Case
Efficiently collects and removes goathead seed pods, preventing damage to lawns and surfaces while allowing for easy disposal of collected pods.
Implementation Method 1
The drum is covered with a sewn sleeve made of neoprene fabric
Implementation Method 2
The drum is covered with a sewn sleeve made of neoprene fabric
Implementation Method 3
There is a scraper bar that is adjustable, based on the size of the goat heads, to scrape the goatheads from the fabric
Implementation Method 4
The catch basin is emptied of goatheads by 'dumping' the catch basin upside down onto a tarp or cement surface

AI summary
The Goathead Roller is a product to get rid of goat head seeds/pods on the ground from the puncture vine family of weeds. It is a 13-inch diameter roller, 24 inches wide, and a handle attached to the roller. The total weight is about 25 pounds. The drum is covered with a sewn sleeve made of neoprene fabric. There is an adjustable scraper bar to scrape the goatheads from the fabric and into a catch basin as the Goathead Roller is rolled forward. The scraper bar has wing nuts on the top of the bar to make it easier to adjust the distance of the scraper bar from the fabric. A catch basin is attached to the roller frame underneath the scraper bar. The catch basin is emptied by ‘dumping’ the catch basin upside down.
