Roller Assembly with Scraper for Spiked Object Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for removing spiked objects like stickers and thorns from surfaces are inefficient and pose risks of injury due to the lack of an effective mechanism for clean-up and disposal.
Innovation Solution
A device with a frame, a roller assembly that rotates to collect spiked objects, a scraper to detach them from the roller, and a collection tray to capture the objects, allowing for easy cleanup and prevention of re-introduction of stickers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a roller is used to pick up stickers from the ground, then collection efficiency is improved, but the device becomes difficult to clean and dispose of collected stickers
Solution Approach 1:
The roller is divided into multiple segments or sections, allowing the collected stickers to be accessed and removed from between the segments. This segmentation enables efficient collection while facilitating easy cleanup by allowing users to access and remove accumulated stickers without disassembling the entire roller.
Solution Approach 2:
A brush or scraper component is introduced to actively remove and extract the collected stickers from the roller surface. This extraction mechanism automatically or semi-automatically transfers stickers from the roller to a collection container, solving the cleanup difficulty while maintaining high collection efficiency.
2Device complexity
If manual removal of stickers is performed, then no special device is needed, but it is time-consuming and poses injury risks
Solution Approach 1:
The roller acts as an intermediary tool between the user and the stickers. Instead of direct manual contact with sharp stickers, the roller collects them through rolling contact, reducing injury risk. The brush component then mediates the transfer of stickers from the roller to a collection container, maintaining simplicity while dramatically improving removal efficiency.
3Productivity
If existing roller devices are used to collect stickers, then collection function is achieved, but frequent manual clearing is required which reintroduces inefficiency and injury risk
Solution Approach 1:
The brush component continuously or periodically removes collected stickers from the roller during operation. This continuous action prevents accumulation of stickers on the roller, eliminating the need for frequent manual clearing interruptions and maintaining continuous collection productivity while reducing user exposure to injury risks.
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
The device efficiently collects spiked objects from surfaces, facilitates easy cleanup, and prevents potential injuries associated with manual removal and existing devices.
Implementation Method 1
the roller assembly is further configured to cause spiked objects disposed along the surface to attach or stick to the roller assembly as the roller assembly rolls over the spiked objects
Implementation Method 2
a scraper configured to detach the spiked objects from the roller assembly as the spiked objects attached to the roller assembly contact the scraper due to the roller assembly rotating
