Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a system that accurately measures and communicates ultraviolet (UV) information to users, allowing them to understand UV exposure levels and locations, as increased UV radiation poses health risks such as skin cancer and cataracts, and existing technologies do not effectively provide this information in a portable and user-friendly manner.
Innovation Solution
A portable UV measurement system comprising a measurement device that detects UV radiation and a display device capable of communication, which acquires position information and stores UV data correlated with measurement positions, allowing users to understand UV exposure levels and locations through a user-friendly interface, including a wearable timepiece that provides notifications and visual indicators for high UV levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultraviolet measurement is performed using a portable device, then measurement accuracy of UV exposure is improved, but the ability to provide location context and historical data is worsened
Solution Approach 1:
The system divides functionality between two devices: a portable measurement device (wearing device) that accurately measures UV exposure, and a separate information terminal (smartphone/computer) that stores and processes location and historical data. This segmentation allows each device to specialize in its strength while working together as an integrated system.
Solution Approach 2:
The wearing device acts as an intermediary that collects UV measurement data and transmits it to the information terminal. The information terminal then correlates this data with location information from GPS and historical storage, providing comprehensive context that neither device could provide alone.
2Loss of information
If position information is acquired and stored with UV data, then understanding of measurement location is improved, but device complexity and data management burden are worsened
Solution Approach 1:
The information terminal automatically performs data correlation without user intervention. When UV measurement data is received from the wearing device, the system automatically associates it with location information from GPS and stores it with timestamp correlation, eliminating the need for manual data management by the user.
Solution Approach 2:
The information terminal serves multiple functions: storing UV measurement data, acquiring location information via GPS, managing historical data, and presenting correlated information to the user. This multi-functionality consolidates complex data management tasks into a single device the user already possesses.
3Reliability
If real-time UV information is provided to users, then user safety and preventive capability are improved, but energy consumption and notification frequency are worsened
Solution Approach 1:
The system performs UV measurements at predetermined time intervals rather than continuously. The wearing device measures UV exposure periodically, transmits data to the information terminal at these intervals, and the terminal processes and stores the information batched, reducing energy consumption while maintaining effective monitoring.
Solution Approach 2:
The information terminal analyzes accumulated UV data and provides selective notifications to the user based on threshold values and patterns. Rather than notifying for every measurement, the system provides feedback only when UV exposure reaches concerning levels or when patterns indicate increased risk, reducing notification frequency while maintaining safety reliability.
