Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a wearable device is designed for continuous health monitoring, then biometric data collection capability is improved, but device comfort and wearability deteriorate due to the need for multiple sensors and components
Solution Approach 1:
The patent combines multiple sensing functions (optical sensing, electrical sensing, temperature sensing) into a single integrated sensing module that contacts the user's skin at one location. This consolidation maintains comprehensive biometric monitoring capability while reducing the overall device size and improving comfort during wear.
2Adaptability or versatility
If the sensing module is designed to accommodate various wrist sizes, then adaptability is improved, but the structural complexity increases due to adjustable strap mechanisms
Solution Approach 1:
The strap is designed with dynamic adjustability, allowing it to be resized and reconfigured to fit different wrist circumferences. This dynamic adjustment capability enables the device to adapt to various users and wrist sizes without requiring multiple fixed-size devices, thereby improving versatility while maintaining manageable complexity through standardized adjustment mechanisms.
3Measurement precision
If the glass-to-metal assembly is designed for optimal optical interaction, then measurement precision is improved, but manufacturing complexity increases
Solution Approach 1:
The optical sensing system employs a nested structure where a glass window is integrated within a metal housing. The glass window is positioned within the metal structure to optimize optical interaction with the skin, while the metal housing provides mechanical support and shielding. This nested arrangement achieves optimal optical measurement conditions while consolidating multiple structural functions into a compact assembly, thereby managing manufacturing complexity.
