Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensing functions are integrated into a single wearable device, then sensing versatility is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensing functions (image sensing for heart rate/blood oxygen/blood pressure, infrared sensing for temperature, sweat sensing, and ultraviolet sensing) into a single integrated sensor module. This merging approach achieves multi-functionality while managing complexity through unified module design rather than separate components.
Solution Approach 2:
The wearable device is designed as a universal platform that can perform multiple sensing functions simultaneously through a single sensor module. The module can detect various biological features (heart rate, blood oxygen, blood pressure, temperature, sweat, ultraviolet exposure) making it adaptable to different monitoring needs without requiring separate devices.
2Adaptability or versatility
If multiple sensing functions are integrated into a single wearable device, then sensing versatility is improved, but manufacturing cost increases
Solution Approach 1:
By merging multiple sensing functions into a single integrated module, the patent reduces the total number of components that need to be manufactured and assembled. This approach can lower manufacturing costs compared to producing and integrating multiple separate sensing devices, despite the increased complexity of the integrated module itself.
3Volume of moving object
If multiple sensing functions are integrated into a single wearable device, then device volume is reduced, but heat dissipation becomes more difficult
Solution Approach 1:
The sensor module is divided into distinct functional regions: an image sensor module for optical sensing, an infrared temperature sensor module for thermal sensing, and other sensing regions for sweat and ultraviolet detection. This segmentation allows each component to have its own heat management characteristics while maintaining a compact integrated structure.
Solution Approach 2:
Different regions of the sensor module are designed with properties optimized for their specific functions. The infrared temperature sensor region is structured to facilitate thermal detection, while the image sensor region is optimized for optical sensing. This local optimization helps manage heat dissipation in different areas of the compact module.
