Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital data transmission is used to connect physiological information sensors to the processing apparatus, then communication interface unification is achieved, but real-time processing capability deteriorates
Solution Approach 1:
The patent segments the data transmission process into multiple subframes within a main frame, allowing different types of data to be transmitted in different time slots. This segmentation enables the processing apparatus to receive and process physiological information data in real-time while maintaining periodic processing for other data types, thus resolving the contradiction between unified digital communication and real-time processing capability.
2Quantity of substance
If multiple physiological information sensors are connected to the processing apparatus, then data acquisition capability is improved, but layout freedom deteriorates
Solution Approach 1:
The patent implements a universal communication interface structure that can accommodate multiple physiological information sensors with different types of data acquisition capabilities. The processing apparatus uses a unified data reception framework that can handle various sensor types through standardized protocols, allowing flexible sensor placement and configuration while maintaining the ability to process data from multiple sources simultaneously.
3Reliability
If periodic processing is maintained for physiological information data, then data processing reliability is improved, but real-time processing efficiency deteriorates
Solution Approach 1:
The patent implements periodic data transmission and processing cycles organized into main frames and subframes. Each main frame contains multiple subframes that are processed in sequence, with specific subframes dedicated to real-time data reception and others dedicated to periodic processing. This periodic structure ensures reliable data processing while maintaining real-time responsiveness for critical physiological information.
