Smart Whiteboard Cleaner with Row Segmentation and Absence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional whiteboards lack self-cleaning capabilities, making it difficult to maintain confidentiality and requiring manual effort for erasing, which can be time-consuming and prone to forgetting.
Innovation Solution
A smart whiteboard system that automatically erases content by dividing the board into rows with switchable erasers, allowing user-selective erasure and automatic cleaning based on user inputs and absence detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual erasing is used, then the whiteboard can be cleaned, but it requires time and manual effort
Solution Approach 1:
The whiteboard system automatically detects user absence and triggers the eraser to clean the board without manual intervention. The system serves itself by monitoring occupancy sensors and autonomously initiating the erasing process, eliminating the need for manual erasing operations.
Solution Approach 2:
The system performs erasing action in advance by detecting user absence and automatically cleaning the board before new content needs to be written. This preliminary automatic action prevents the accumulation of old content and eliminates the need for manual erasing at the moment it is needed.
2Reliability
If the entire whiteboard is erased, then confidentiality is maintained, but all content is lost including useful information
Solution Approach 1:
The whiteboard is divided into multiple selectable regions or rows, each with its own erasure control. Users can selectively erase only specific segments containing confidential information while preserving other segments with useful content, achieving both confidentiality and information retention.
Solution Approach 2:
Different regions of the whiteboard have different erasure states - some areas are erased while others retain content. The system applies erasure locally to specific segments rather than uniformly across the entire board, allowing selective confidentiality protection.
3Loss of time
If automatic erasing is implemented, then time is saved, but the system complexity increases
Solution Approach 1:
The whiteboard system incorporates occupancy sensors and automatic control logic that enable self-service functionality. The system monitors itself and autonomously triggers the eraser based on detected user absence, saving time without requiring complex external automation systems.
Solution Approach 2:
Manual mechanical erasing operations are replaced with an automated electronic control system that uses sensors and microcontrollers to trigger the eraser motor. This substitution eliminates manual labor while implementing a relatively simple electronic control architecture.
4Loss of information
If selective region erasing is enabled, then content preservation is possible, but the control interface becomes more complex
Solution Approach 1:
The whiteboard surface is divided into multiple independently controllable regions or rows. Each segment can be selectively erased by triggering its corresponding eraser unit, allowing users to preserve useful content in some regions while removing confidential information from others.
Solution Approach 2:
Instead of erasing the entire whiteboard or no part of it, the system enables partial erasure of only the necessary segments. This partial action approach erases exactly what is needed for confidentiality while preserving other content, optimizing the balance between security and information retention.

AI summary
A method to erase at least a certain amount of content presented on a whiteboard with a whiteboard cleaner is provided. The method includes uniformly dividing whiteboard screen into plurality of horizontal rows, wherein each row is configured with a switch button. The method includes selecting at least one switch button, by a user, to signify the certain amount of content that the user admires to erase. Further, the method includes receiving a command, by a transceiver, to automatically erase the certain amount of content selected by the user, wherein the command corresponds to an electronic signal configured with each switch button. The method further includes determining, by a processor, absence of the user for a predetermined time period, wherein based on determination, the system shuts off the white board to restrict access of unknown person to view the content of the whiteboard.
