Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a comprehensive sleep monitoring system with multiple sensors and functionalities is implemented, then the information completeness and functionality are improved, but the device complexity increases making it difficult to operate and prone to errors
Solution Approach 1:
The system is divided into three main modules: a sensing unit with multiple sensors (pressure, temperature, humidity, light, sound, motion), a bedside device for data processing and control, and a mobile terminal for user interaction. This segmentation allows each module to have specialized functions, reducing overall system complexity while maintaining comprehensive monitoring capabilities.
Solution Approach 2:
The bedside device serves multiple functions: it processes data from various sensors, controls environmental parameters (lights, sounds, temperature), provides user interface operations, and communicates with the mobile terminal. This multi-functionality consolidates diverse operations into a single device, improving ease of operation despite comprehensive functionality.
2Adaptability or versatility
If multiple sensors and processing functions are integrated into the system, then the functionality and information provided are improved, but the ease of operation deteriorates
Solution Approach 1:
The mobile terminal acts as an intermediary between the user and the complex sensing/processing system. It provides a simplified interface for users to view sleep data, receive notifications, and control system functions without needing to understand the underlying sensor operations or data processing complexity.
Solution Approach 2:
The system automatically processes sensor data, identifies sleep stages, detects health risks, and generates notifications without requiring user intervention. The bedside device autonomously correlates data from multiple sensors and determines when to alert users or medical personnel, reducing operational burden on users.
3Measurement precision
If the system correlates data from multiple sensors and provides detailed sleep analysis, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The system merges data from multiple independent sensors (pressure, temperature, humidity, light, sound, motion) into a unified analysis framework. The bedside device correlates these diverse data streams to comprehensively determine sleep stages and detect health risks, achieving high measurement precision through integrated multi-sensor analysis.
