Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physiological detection is performed through hand measurements, then health state monitoring is enabled, but measurement precision and reliability are insufficient
Solution Approach 1:
The patent replaces traditional mechanical hand-based physiological detection with an optical imaging system that captures eye images. The image capturing module uses optical fields to detect microvascular characteristics in the sclera and eyelid, substituting mechanical measurement with non-contact optical detection to improve precision while reducing device complexity.
Solution Approach 2:
The patent introduces an information processing system as an intermediary between the image capturing module and the final physiological state determination. This intermediary processes eye images to extract microvascular characteristics, enabling accurate physiological state detection without requiring complex direct measurement devices.
2Measurement precision
If eye images are continuously captured to obtain accurate physiological signals, then measurement precision improves, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by allowing the image capturing module to capture eye images either continuously or discontinuously based on predetermined conditions. This enables the system to balance measurement precision with energy consumption by adjusting the capture frequency according to actual monitoring needs.
Solution Approach 2:
The patent applies partial action by capturing only the necessary eye images required for physiological state detection rather than continuous full-frame imaging. The system processes eye images to extract only the relevant microvascular characteristics, reducing overall energy consumption while maintaining detection accuracy.
3Adaptability or versatility
If multiple modules are integrated for comprehensive physiological monitoring, then functionality and versatility improve, but device complexity increases
Solution Approach 1:
The patent merges multiple functional modules (image capturing module, wireless transmission module, information providing module, and power supply module) into a single integrated physiological state detection device. This combining approach provides comprehensive physiological monitoring functionality while managing device complexity through unified system architecture.
Solution Approach 2:
The patent achieves multi-functionality by designing a device that can perform eye image capture, wireless data transmission, information presentation, and power management all within one system. The image capturing module can detect various physiological states (fatigue, stress, health conditions) through different microvascular characteristics, providing universal applicability.
