Continuous and long-time usage of traditional diapers can lead to health issues such as rashes and bacterial infections due to inadequate monitoring of wetting and other vital signs, requiring real-time health condition monitoring without caregiver intervention.
Innovation Solution
A smart diaper system with a low-cost screen-printed sensor array embedded in the diaper, capable of detecting body temperature, respiration rate, wetness, and volatile organic compounds, transmitting data wirelessly to peripheral devices via Bluetooth, allowing for non-invasive and continuous monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional diapers are used for continuous monitoring, then caregiver intervention is required, but this increases labor burden and reduces monitoring efficiency
Solution Approach 1:
The diaper system performs self-monitoring of health metrics including body temperature, respiration rate, and wetting levels through embedded sensors that automatically detect and transmit data without requiring caregiver intervention or manual checking
Solution Approach 2:
Manual visual inspection by caregivers is replaced with electronic sensor arrays that continuously monitor physiological parameters, substituting mechanical human observation with automated electronic detection systems
2Adaptability or versatility
If multiple sensors are integrated into the diaper, then health monitoring capability is improved, but manufacturing complexity increases
Solution Approach 1:
A single sensor array integrates multiple sensing functions including temperature sensing, respiration rate detection, and wetting level monitoring into one unified system, allowing the diaper to perform diverse health monitoring tasks simultaneously
Solution Approach 2:
Multiple sensor types and electronic components are combined into a single integrated sensor array module that is pre-assembled and then incorporated into the diaper during manufacturing, simplifying the production process while maintaining comprehensive monitoring capability
3Reliability
If real-time monitoring is implemented, then health issue prevention is improved, but data transmission requirements increase system complexity
Solution Approach 1:
The system continuously monitors physiological parameters and provides real-time feedback through wireless transmission to external devices, enabling immediate detection of health changes and timely intervention to prevent health issues
Solution Approach 2:
A wireless transmission module serves as an intermediary between the embedded sensor array and external monitoring devices, handling data communication without requiring direct physical connections or complex wiring within the diaper structure
