Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional UV exposure monitoring methods are used, then device complexity is reduced, but measurement precision deteriorates due to inability to accurately measure indirect UV radiation
Solution Approach 1:
The system divides UV radiation measurement into multiple components by using a grid of individual UV sensors that can detect direct and reflected radiation separately. Each sensor in the grid contributes to the overall measurement, allowing precise characterization of different UV exposure pathways without requiring a single complex sensor system.
Solution Approach 2:
The UV sensor grid system serves multiple functions simultaneously: it measures direct UV radiation, detects reflected UV radiation from surfaces, tracks user position and time duration, and provides cumulative exposure calculations. This multi-functionality achieves high measurement precision while distributing complexity across multiple simple, identical sensor units rather than requiring one complex system.
2Reliability
If comprehensive UV exposure tracking is implemented, then reliability of skin cancer risk assessment improves, but ease of operation deteriorates due to multiple data collection requirements
Solution Approach 1:
The system automatically collects and processes UV exposure data without requiring active user participation. The sensor grid continuously measures radiation levels, the mobile device automatically tracks position and time duration, and the processor computes cumulative exposure and provides alerts. This self-service approach maintains high reliability through comprehensive data collection while maximizing ease of operation by eliminating manual user input requirements.
Solution Approach 2:
The system provides real-time feedback to users through alerts and notifications that indicate when UV exposure limits are approaching or exceeded. This feedback mechanism maintains reliable risk assessment by continuously monitoring exposure parameters while simplifying operation for users who receive automated guidance without needing to manually manage their own exposure tracking.
3Productivity
If real-time UV monitoring is provided, then productivity of UV protection management improves, but use of energy increases due to continuous sensor operation
Solution Approach 1:
The UV sensors operate in periodic cycles rather than continuous mode, activating to take measurements at intervals and then entering low-power states. The mobile device similarly samples position and time data at periodic intervals rather than continuously. This periodic operation maintains adequate productivity for UV protection management by capturing sufficient exposure data while significantly reducing energy consumption compared to continuous operation.
Solution Approach 2:
The system replaces continuous mechanical sensing with event-driven measurement approaches where sensors activate based on environmental conditions or time intervals rather than continuous operation. The processor uses algorithms that can calculate cumulative exposure from discrete measurement points rather than requiring continuous data streams, reducing energy usage while maintaining management efficiency.
