Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used to connect sensors to centralized units, then signal transmission is achieved, but signal artifacts occur and patient comfort deteriorates
Solution Approach 1:
The patent extracts the harmful wired connection component from the system by implementing a fully wireless architecture. The wireless sensor node contains all necessary components (sensor, processor, transceiver, power source) to transmit data without physical cables, thereby eliminating signal artifacts caused by wired connections while maintaining reliable signal transmission.
Solution Approach 2:
The patent replaces the mechanical wired connection system with an electromagnetic wireless communication system. The transceiver component uses radio frequency signals to transmit patient data from the sensor node to the centralized unit, substituting physical cable connections with electromagnetic wave transmission, which eliminates mechanical interference and signal artifacts.
2Reliability
If wired connections are used, then data transmission is reliable, but patient mobility and comfort are restricted
Solution Approach 1:
The patent removes the constraining wired connection from the monitoring system, allowing patients to move freely. The wireless sensor node transmits data through air interface using radio frequency signals, completely eliminating the physical tether that restricted patient mobility in traditional wired systems.
Solution Approach 2:
The patent substitutes the mechanical constraint of wired connections with electromagnetic wireless communication. This allows patients to engage in daily activities, exercise, and move throughout their environment without being tethered to monitoring equipment, while maintaining continuous reliable data transmission.
3Duration of action of stationary object
If wired monitoring devices are used, then continuous monitoring is achieved, but water resistance and bathing capability are lost
Solution Approach 1:
The patent extracts the water vulnerability associated with wired connections and replaces it with a wireless architecture. The wireless sensor node can be designed with water-resistant sealing, allowing patients to bathe and swim while maintaining continuous monitoring capability through wireless data transmission that is not affected by water exposure.
Solution Approach 2:
The wireless monitoring system provides universal functionality across different environments including water. The sensor node can operate continuously during bathing, swimming, and other water-based activities while maintaining monitoring function, making the system adaptable to various patient lifestyles and activities.
4Quantity of substance
If traditional monitors are used, then basic vital sign recording is achieved, but two-way communication and emergency alerting are not available
Solution Approach 1:
The wireless sensor node incorporates multiple functions including sensing, processing, wireless transmission, and two-way communication capabilities. The transceiver can both send patient data to the centralized unit and receive alerts or commands, enabling emergency notification systems where patients can be alerted to seek medical attention or where emergency services can be notified automatically.
Solution Approach 2:
The system implements feedback through two-way communication between the sensor node and centralized unit. The centralized unit can send alerts, notifications, or control signals back to the wireless sensor node, enabling interactive monitoring, emergency alerting, and remote system management capabilities that enhance patient safety and response time.
