Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a wearable device with multiple sensors is used to track UV and light exposure, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines UV sensors, IR sensors, and ambient light sensors into a single wearable device unit. This merging of multiple sensing functions into one device achieves precise multi-spectral exposure tracking while avoiding the complexity of managing separate devices for each measurement type.
Solution Approach 2:
The wearable device is designed with multi-functionality, serving as a universal monitoring tool that tracks UV radiation, infrared radiation, and visible light exposure simultaneously. This universal approach improves measurement precision across different radiation types without requiring multiple specialized devices.
2Reliability
If real-time monitoring and analysis are implemented, then reliability of exposure information is improved, but use of energy increases
Solution Approach 1:
The system implements periodic action by calculating UV index and cumulative dose at specific intervals rather than continuously processing data in real-time. This approach maintains reliable exposure information while significantly reducing energy consumption compared to continuous real-time processing.
Solution Approach 2:
The patent uses an intermediary computing device to perform the energy-intensive calculations of UV index and cumulative dose analysis. The wearable sensor collects data with minimal energy use, then transfers it to an external computing device for processing, thereby maintaining reliability while minimizing the wearable device's power consumption.
3Object-affected harmful factors
If personalized protection recommendations are provided, then object-affected harmful factors are reduced, but device complexity increases
Solution Approach 1:
The patent employs an intermediary computing device to handle the complex algorithms for personalized protection recommendations. The wearable device collects exposure data and user profile information, then the intermediary device processes this data through sophisticated algorithms to generate personalized advice, reducing skin damage risk without burdening the wearable device with excessive complexity.
Solution Approach 2:
The system replaces complex mechanical or computational processing within the wearable device with software-based algorithms running on an external computing device. This substitution allows for sophisticated personalized recommendation engines that reduce harmful UV exposure effects without increasing the hardware complexity of the wearable sensor itself.
