Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible piezoelectric film devices are used for sleep monitoring, then sleep monitoring capability is achieved, but non-invasive blood glucose detection capability is lost
Solution Approach 1:
The patent combines sleep monitoring and non-invasive blood glucose detection functions into a single flexible piezoelectric film device. The detection module integrates optical components (light emitting unit, sensing unit) with the piezoelectric structure, allowing both sleep monitoring and blood glucose detection to be performed simultaneously by the same device without requiring separate systems.
Solution Approach 2:
The flexible piezoelectric film device is designed to perform multiple functions: it can detect sleep states through piezoelectric sensing and simultaneously detect blood glucose levels through the integrated detection module with optical components. This multi-functional design allows a single device to replace what would traditionally require separate monitoring systems.
2Adaptability or versatility
If blind holes are added to embed detection module, then non-invasive blood glucose detection is enabled, but device structure complexity increases
Solution Approach 1:
The detection module is embedded within the flexible piezoelectric film structure by placing it in blind holes formed in the protective layer. The light emitting unit and sensing unit are positioned within these cavities, nesting the optical detection components inside the existing piezoelectric device architecture rather than adding external components.
Solution Approach 2:
The patent transitions from a planar two-dimensional structure to a three-dimensional structure by forming blind holes (cavities) in the protective layer. This vertical dimensionality change allows the detection module to be embedded within the device thickness, integrating optical components without significantly increasing the device's footprint area.
