Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional smart wearable devices are used for health monitoring, then basic functions like sleep and heart rate monitoring are provided, but the ability to detect drowning in dangerous environments is lacking
Solution Approach 1:
The wearable device integrates multiple detection functions beyond basic health monitoring. It combines temperature sensing, pressure sensing, and acceleration sensing capabilities into a single device, enabling it to detect various environmental conditions and specifically identify drowning situations through multi-parameter analysis.
Solution Approach 2:
The drowning detection function is segmented into multiple independent detection modules: temperature detection module, pressure detection module, and acceleration detection module. Each module independently monitors its specific parameter, and their results are综合分析 (comprehensively analyzed) to determine drowning status, improving overall detection reliability.
2Measurement precision
If multiple detection signals are collected and analyzed to improve drowning detection accuracy, then detection precision is improved, but device complexity increases
Solution Approach 1:
The complex detection system is divided into separate functional modules: temperature detection module, pressure detection module, and acceleration detection module. Each module handles a specific sensing task independently, making the overall complex system manageable through modular design while maintaining high detection precision.
Solution Approach 2:
Multiple detection modules (temperature, pressure, acceleration) are merged into a single integrated wearable device with a unified control unit that coordinates all sensing operations. This combining approach enables comprehensive drowning detection through multi-parameter analysis while managing system complexity through centralized control.
3Speed
If real-time analysis of multiple detection signals is performed to quickly detect drowning, then response speed is improved, but energy consumption increases
Solution Approach 1:
The device performs periodic detection and analysis of temperature, pressure, and acceleration signals rather than continuous monitoring. The control unit analyzes these signals at regular intervals to determine drowning status, enabling quick response to dangerous situations while reducing overall energy consumption compared to continuous real-time analysis.
