Vision Protection System with Distance Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic device users, especially children, often fail to take regular breaks to rest their eyes, leading to eye strain and increased risk of nearsightedness due to prolonged screen time, with existing methods lacking effective enforcement to interrupt their usage and monitor proper viewing distance.
Innovation Solution
A system that automatically switches electronic devices from a working mode to a resting mode after a predetermined time, featuring a distance detector to ensure proper viewing distance, with customizable settings for age-specific eye exercises and reminders, and the option to bypass for emergencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electronic device continuously operates in working mode to maintain productivity, then user convenience and device utilization are improved, but the viewer's eyesight deteriorates due to prolonged screen time
Solution Approach 1:
The system implements periodic switching between working mode and resting mode based on predetermined time intervals. A timer module counts working time and automatically triggers mode switching, ensuring regular breaks are taken without manual intervention. This periodic action resolves the contradiction by enforcing eye rest periods while maintaining overall device productivity.
Solution Approach 2:
The system uses feedback from the timer module and mode switch signals to control the display state. When working time reaches the predetermined threshold, the system receives feedback and automatically switches to resting mode, blanking the screen. This closed-loop feedback mechanism ensures continuous monitoring and enforcement of eye protection protocols.
2Object-affected harmful factors
If the system automatically switches to resting mode to protect eyesight, then eye strain is reduced, but the viewer's work or entertainment is interrupted
Solution Approach 1:
The system performs preliminary actions by pre-setting the working time threshold and rest mode parameters before actual use. The timer module is pre-configured with predetermined time values, and the system automatically executes the mode switch when the threshold is reached, eliminating the need for user decision-making at the moment of interruption.
Solution Approach 2:
The system serves itself by automatically monitoring working time, detecting when the threshold is reached, and executing the mode switch without requiring user intervention. The timer module and control logic work autonomously to enforce eye protection protocols, reducing the burden on the user to manually manage break times.
3Object-affected harmful factors
If the screen is blanked out during resting mode to force eye rest, then eyesight protection is improved, but the user loses access to their current work content
Solution Approach 1:
The system extracts the essential function of eye protection by selectively blanking only the display screen during resting mode, while leaving other system functions intact. The timer module and mode control logic remain operational, and the system can quickly restore the display when returning to working mode, minimizing information loss while achieving the vision protection goal.
4Object-affected harmful factors
If a distance detector is added to monitor viewing distance, then eyesight protection is enhanced, but the device complexity increases
Solution Approach 1:
The system achieves multi-functionality by integrating the distance detector with the existing mode switching mechanism. The distance detection capability is combined with the timer and display control functions, allowing a single system to monitor both time-based and distance-based eye protection parameters, thereby reducing overall system complexity through functional integration.

AI summary
The vision protection method and system thereof is provided to ensure a viewer to rest his/her eyes after viewing on an electronic device for a certain period, wherein the eyesight protection method includes the steps of initially counting down a predetermined working time of a working mode, switching the working mode to a resting mode to temporarily halt the current working mode of the electronic device, and resuming the operation of the working mode that the viewer was previously working on. In that manner, the viewer is enforced to rest his/her eyes after every certain period.
