Personalized UV Exposure Alerts for Safe Sun Time Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack a practical way to track UV exposure and provide timely alerts for safe sun exposure, leading to potential health issues such as skin cancer and burns, with the UV index offering no guidance on safe activity levels.
Innovation Solution
A computerized system that allows users to input skin color, familial history, and SPF, calculating a maximum sun exposure time and providing alerts when reached, utilizing a mobile app and Arduino Uno with Bluetooth connectivity for real-time monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UV index is used to monitor sun exposure, then UV radiation levels can be measured, but it does not provide guidance on safe activity levels or total exposure time
Solution Approach 1:
The system performs preliminary actions by calculating the maximum safe exposure time before actual exposure occurs. It computes this value in advance based on user-specific parameters (skin color, age, gender) and environmental factors (UV index, time of day, season), then uses this pre-calculated limit to guide the user's sun exposure activities.
Solution Approach 2:
The system implements continuous feedback by monitoring actual UV exposure time in real-time and comparing it against the calculated maximum safe exposure time. When the exposure limit is approached or reached, the system provides alerts and notifications to warn the user, creating a closed-loop feedback mechanism that actively manages sun safety.
2Measurement precision
If personalized exposure limits are calculated based on skin color and familial history, then accuracy of exposure guidance is improved, but system complexity increases
Solution Approach 1:
The system applies parameter changes by adjusting the maximum exposure time calculation based on multiple user-specific parameters including skin color (Fitzpatrick scale), age, gender, and familial history of skin cancer. These parameters modify the base exposure limit to create a personalized recommendation that accurately reflects individual risk factors.
3Reliability
If real-time monitoring and alerts are implemented, then user safety is improved, but energy consumption and device requirements increase
Solution Approach 1:
The system implements self-service by using the device's existing sensors (such as ambient light sensors or GPS) and processing capabilities to perform the monitoring function. Rather than requiring external specialized equipment, the system leverages what the mobile device already has to track exposure time and deliver alerts, minimizing additional energy and hardware requirements.
