Wearable Display Eyeball Protection Module for Eye Fatigue Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices with image display modules do not effectively protect users' eyes from fatigue, as they lack mechanisms to monitor and respond to blink periods and eyeball temperatures, leading to potential eye strain during prolonged use.
Innovation Solution
A wearable device equipped with an image display module, a lens frame, and an eyeball protection module that includes blink sensing units, temperature detection units, and spray driving units to induce blinking and apply air, water, or tear solution to the eyes based on monitored blink periods and temperatures, thereby reducing eye fatigue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an image display module is provided in a wearable device, then display functionality is achieved, but user eye fatigue increases during prolonged use
Solution Approach 1:
The system performs preliminary detection of blink patterns and temperature changes before significant eye fatigue occurs. The blink detection unit continuously monitors blink frequency, and the temperature detection unit tracks eyeball temperature, enabling the system to take preventive action by spraying tear solution or adjusting display parameters before fatigue sets in.
Solution Approach 2:
The system establishes a feedback loop where detection units continuously monitor eye health parameters (blink frequency, temperature), and control units adjust display module operations based on this feedback. When fatigue indicators are detected, the system automatically modifies display brightness, refresh rate, or triggers eye protection mechanisms.
2Reliability
If monitoring mechanisms for blink period and temperature are added, then eye protection capability is improved, but device complexity increases
Solution Approach 1:
The wearable device integrates multiple functions into unified components. The detection units serve dual purposes: monitoring both blink patterns and temperature changes for eye health assessment. The control unit coordinates multiple protection strategies (spray activation, display parameter adjustment) through a single integrated control system, reducing overall complexity despite enhanced functionality.
Solution Approach 2:
The system enables the display module to self-regulate based on detected eye conditions. When fatigue is detected through blink or temperature monitoring, the control unit automatically adjusts display parameters without requiring user intervention. The eye protection mechanism serves itself by using detection data to trigger appropriate protective actions.
3Reliability
If the eyeball protection module sprays air, water, or tear solution to induce blinking, then eye protection is enhanced, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The system uses tear solution or moisture as an intermediary substance to facilitate eye protection. Rather than directly stimulating the eye, the spray mechanism delivers a benign substance that naturally induces blinking and lubricates the eye surface. This intermediary approach enhances protection effectiveness while avoiding direct mechanical or chemical stimulation that would complicate manufacturing.

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 effectively reduces eye fatigue by monitoring and responding to user eye activity, improving user satisfaction and eye protection during extended use by displaying fatigue increase messages and adjusting display settings accordingly.
