Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual washing of foam portions of board erasers is harmful to health and inefficient, as it requires direct contact with chalk dust and takes a lot of time.
Innovation Solution
A device with a case, cleaning boxes, a flushing mechanism, pressing parts, and a rotating mechanism that allows for automatic cleaning of board erasers, where water is used to flush and squeeze out dust from the erasers without manual contact, and the wastewater is stored and reused.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual washing of foam portion is used, then the user can clean the board eraser, but the user's hands contact chalk dust which is harmful to health
Solution Approach 1:
The patent introduces a container with water as an intermediary medium between the user and the chalk dust. The foam portion is washed inside the container, allowing water to capture and contain the chalk dust during the cleaning process, preventing direct contact between the user's hands and the harmful dust particles.
Solution Approach 2:
The system enables the board eraser to clean itself through automatic flushing mechanisms. Water is automatically supplied to rinse the foam portion, and the wastewater containing chalk dust is collected and disposed of automatically, eliminating the need for manual handling of contaminated water.
2Productivity
If manual washing of foam portion is used, then the user can clean the board eraser, but the cleaning process takes lots of time
Solution Approach 1:
The board eraser cleaning system performs self-service through automatic flushing mechanisms. Water is automatically supplied to rinse the foam portion, and the wastewater containing chalk dust is collected and disposed of automatically, eliminating the need for manual handling of contaminated water and significantly reducing cleaning time.
Solution Approach 2:
The system maintains continuous water flow during the cleaning process, ensuring that the foam portion is constantly rinsed without interruption. This continuous action prevents re-deposition of chalk dust and ensures thorough cleaning in minimal time.
3Object-affected harmful factors
If water is used to flush the board eraser, then chalk dust can be removed, but wastewater containing chalk dust needs to be disposed of
Solution Approach 1:
The container serves as an intermediary that captures and contains the wastewater containing chalk dust. Instead of allowing the contaminated water to be dispersed or require manual disposal, the container collects it in a centralized location, making disposal more efficient and preventing secondary contamination.
Solution Approach 2:
The system facilitates the discarding of wastewater containing chalk dust through automatic drainage or collection mechanisms. The container design allows for easy emptying and reuse, enabling the recovery and reuse of clean water while efficiently disposing of contaminated water.
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 enables automatic and efficient cleaning of board erasers, preventing user exposure to chalk dust and significantly reducing the time required for the cleaning process.
Implementation Method 1
Water can enter the cleaning box from the water inlet to clean the board eraser placed in the cleaning box
Implementation Method 2
The first power member which may be a pump is connected with the piping and is configured to supply impetus to water in the piping
Implementation Method 3
Each pressing part is connected with a second power member that is configured to drive the pressing part connected with it to slide

AI summary
Device and method for cleaning board erasers are provided. The device includes a case, one or more cleaning boxes, a flushing mechanism, one or more pressing parts and a rotating mechanism. Each cleaning box is configured for holding and cleaning a board eraser. The flushing mechanism includes a piping and a first power member for pumping water into the cleaning boxes to flush and clean the board erasers placed in the cleaning boxes. The rotating mechanism is configured to drive the cleaning boxes to rotate to set in an initial state or a working state. In the initial state, a user can put a board eraser into a cleaning box. In the working state, the board eraser in the cleaning box can be flushed and cleaned, and can be pressed by the pressing part to squeeze out water in the board eraser.
