Rollable Grid-Casing Dirt Remover for Currentless Bag Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dirt removers require manual operation and are not suitable for cleaning difficult-to-access areas, such as small containers like bags or handbags, as they are typically large and electrically powered.
Innovation Solution
A powerless, automatic dirt remover with a grid-shaped, rollable casing and a dirt-absorbing body that moves independently, using static or adhesive surfaces to attract dirt through openings in the casing, allowing it to roll and collect dirt without electricity, especially in containers like bags or suitcases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used for dirt removal, then the dirt remover can be simple in structure, but it cannot clean difficult-to-access areas and requires active user operation
Solution Approach 1:
The dirt remover is designed to move and clean surfaces automatically without requiring manual operation. The device uses its own weight and the movement of the container it is placed in to roll across surfaces and collect dirt through its adhesive surface, making it self-sufficient in performing the cleaning function.
Solution Approach 2:
The dirt remover is divided into functional components: a rollable casing body with openings, a dirt-receiving body with adhesive surface, and a drive mechanism. This segmentation allows each component to perform its specific function while keeping the overall structure relatively simple.
2Area of stationary object
If the dirt remover is made large for effective cleaning, then it can clean surfaces effectively, but it cannot be used in small containers like bags or handbags
Solution Approach 1:
The dirt remover utilizes the third dimension by rolling movement. Instead of expanding the cleaning surface area in two dimensions, the device maintains a compact volume by using a cylindrical/rollable shape that can move through the container space, effectively accessing areas that would be unavailable to a larger flat surface.
Solution Approach 2:
The dirt remover is designed to be placed inside containers like bags or handbags. The compact rollable structure nests within the container while its adhesive surface extends through openings to contact and clean the inner surfaces of the container, maximizing cleaning capability within limited space.
3Extent of automation
If electricity is used to power the dirt remover, then automatic movement is achieved, but the device becomes complex and cannot be used in small containers
Solution Approach 1:
The dirt remover exploits the movement of the container it is placed in as its power source. When the user moves or carries the container (bag, handbag, etc.), this movement is transmitted to the dirt remover, causing it to roll automatically. The device converts the container's movement into its own rolling motion through friction and mechanical coupling, requiring no separate power system.
Solution Approach 2:
The container itself acts as an intermediary between the user's movement and the dirt remover's operation. The user's handling of the container transfers mechanical energy to the dirt remover, which then uses this energy to move and clean surfaces automatically without requiring an internal power source.
4Strength
If the casing body is solid for structural integrity, then it protects internal components, but it cannot provide access for the dirt-absorbing body to interact with the environment
Solution Approach 1:
The casing body is designed with a grid shape featuring multiple openings distributed across its surface. This porous-like structure allows the adhesive surface of the dirt-receiving body to contact and interact with dirt on external surfaces while the grid framework maintains sufficient structural strength to protect internal components and provide rollable integrity.
Solution Approach 2:
Different regions of the casing body have different properties: the grid areas provide openings for environmental access and dirt contact, while the connecting framework maintains structural strength. The adhesive surface on the dirt-receiving body is concentrated in specific locations to maximize dirt collection while minimizing interference with the rollable movement.
