Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physiological detection devices use traditional measurement methods, then device structure is simple, but measurement precision and reliability are insufficient
Solution Approach 1:
The patent replaces traditional mechanical contact-based physiological measurement methods with an optical imaging system. The head-mounted device uses image capturing modules to photograph microvascular characteristics in the user's eyes, eliminating the need for physical contact sensors while significantly improving measurement precision and reliability of physiological state detection.
Solution Approach 2:
The patent introduces an information processing system as an intermediary between the image capturing module and the final physiological state analysis. This intermediary processes the captured images, extracts microvascular characteristics, and generates physiological state signals, thereby enhancing detection accuracy while keeping the head-mounted device structure relatively simple.
2Reliability
If physiological detection devices implement continuous monitoring, then health management effectiveness is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by allowing the image capturing module to continuously or discontinuously capture eye images within a predetermined period. The system can operate in continuous monitoring mode for critical physiological parameters or switch to periodic sampling for stable conditions, thereby maintaining reliability while managing energy consumption effectively.
Solution Approach 2:
The patent applies dynamics by making the monitoring mode adjustable between continuous and discontinuous operation. The system can dynamically switch between these modes based on user needs, physiological stability, and power availability, optimizing the balance between continuous monitoring capability and energy consumption.
3Adaptability or versatility
If head-mounted device includes multiple functional modules, then physiological state detection capability is enhanced, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the head-mounted device with multiple functional modules that can operate independently or in combination. The device includes image capturing modules for physiological detection, wireless transmission modules for data communication, information providing modules for feedback, and power supply modules for energy management, all controlled by a signal control module, enabling versatile physiological state detection while managing complexity through integrated control.
4Measurement precision
If image capturing module continuously captures eye images, then physiological state signal accuracy is improved, but data transmission load increases
Solution Approach 1:
The patent applies extraction by having the information processing system extract only the essential physiological state signals from the continuously captured eye images. Instead of transmitting all raw image data, the system processes images locally to extract microvascular characteristics and generates compact physiological state signals, thereby maintaining accuracy while significantly reducing data transmission load.
