Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If analog signals are used for patient monitoring, then signal transmission is simple, but signal attenuation and distortion occur during transmission
Solution Approach 1:
The patent replaces the traditional analog electrical signal transmission system with a digital communication system. The monitoring device converts physiological signals to digital data, which is then transmitted through the cable to the display device. This substitution eliminates signal attenuation and distortion issues inherent in analog transmission, as digital signals can be regenerated without loss of quality.
2Adaptability or versatility
If multiple specialized cables are used for different sensors, then each cable is optimized for its specific sensor, but cable management becomes complex during patient transfer
Solution Approach 1:
The patent creates a universal cable design that can connect to multiple types of sensors through interchangeable connectors. The cable includes a first connector for the monitoring device and a second connector that can be exchanged to match different sensor types. This allows a single cable to serve multiple functions and sensor types, eliminating the need for multiple specialized cables and simplifying cable management during patient transfers.
Solution Approach 2:
The patent implements a dynamic connector system where the second connector can be easily exchanged or replaced based on the sensor type being used. This dynamic adaptability allows the cable to change its configuration to match different sensors, providing versatility while maintaining ease of operation. The interchangeable connector design enables quick switching between sensor types without requiring multiple dedicated cables.
3Ease of manufacture
If analog cables with specific connector configurations are used, then connector design is simple, but sensor combinations are limited with a single monitoring device
Solution Approach 1:
The patent designs the cable with a universal interface capability, where the second connector can be exchanged to match different sensor types. This allows a single monitoring device to work with multiple sensor combinations by simply changing the connector on the cable, not the entire cable assembly. The monitoring device itself remains unchanged, but the interchangeable connectors provide the necessary adaptability for various sensor configurations.
