Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric detection is used for user identification, then security and accuracy of user identification is improved, but system complexity and cost increase
Solution Approach 1:
The system divides user identification into multiple stages: first using simple methods (ID card, barcode, QR code) for initial identification, then using biometric detection (fingerprint, face recognition, iris) for verification. This segmentation allows the system to achieve high reliability without requiring complex biometric systems to operate alone, thereby reducing overall system complexity while maintaining security.
2Loss of energy
If continuous monitoring is implemented for energy management, then energy conservation is improved, but device complexity and power consumption increase
Solution Approach 1:
The system automatically monitors device usage patterns, user behavior, and environmental conditions without requiring manual intervention. The control host continuously collects data from various sensors and devices, analyzes energy consumption patterns, and automatically adjusts device operations to optimize energy usage. This self-service approach enables continuous monitoring while minimizing the need for additional complex monitoring infrastructure.
Solution Approach 2:
The system implements real-time feedback loops where sensor data about device usage and environmental conditions is continuously fed back to the control host, which then automatically adjusts device operations. This feedback mechanism enables the system to respond dynamically to changing conditions, optimizing energy conservation without requiring overly complex manual monitoring and control systems.
3Adaptability or versatility
If multiple detection devices are integrated for comprehensive control, then functionality and user experience are improved, but system complexity and coordination difficulty increase
Solution Approach 1:
The control host is designed as a universal platform that can manage multiple types of detection devices and controlled devices through standardized communication protocols. Rather than requiring specialized control logic for each device type, the control host provides a unified interface and control mechanism that works across diverse devices, thereby reducing integration complexity while maintaining comprehensive functionality.

Implementation Method 1
An optical pulse oximeter generally emits a red light beam (wavelength of about 660 nm) and an infrared light beam (wavelength of about 910 nm) to penetrate a part of the human body and detects an intensity variation of the penetrating light based on the feature that the oxyhemoglobin and the deoxyhemoglobin have different absorptivities in particular spectrum
