Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If medical information is constantly transmitted from the medical device, then the information availability is improved, but the power consumption increases
Solution Approach 1:
The medical device transmits information only at periodic intervals when triggered by a request signal from the information device, rather than continuously transmitting. This periodic transmission mode ensures information is available when needed while allowing the device to enter low-power states between transmissions, thus resolving the contradiction between information availability and power consumption.
2Device complexity
If the medical device uses simple configuration with sound wave transmission, then the device complexity is reduced, but the transmission reliability may be affected
Solution Approach 1:
The system uses sound waves as an intermediary medium for transmitting medical information from the medical device to the information device. This acoustic intermediary allows simple device configuration without complex wireless communication hardware, while maintaining reliable transmission through the physical properties of sound wave propagation and reception.
3Loss of time
If the request signal reception unit receives signals continuously, then the response time is improved, but the power consumption increases
Solution Approach 1:
The request signal reception unit operates periodically or on-demand rather than continuously monitoring for signals. The device can enter sleep modes between request signal cycles, reducing power consumption while still maintaining the capability to respond promptly when a request signal is transmitted by the information device.
4Reliability
If the medical device transmits identification information for every request, then the security is improved, but the communication overhead increases
Solution Approach 1:
The medical device performs preliminary authentication by verifying identification information before transmitting medical information in response to a request signal. This preliminary security check ensures that only authorized information devices can retrieve data, while the authentication process is integrated into the request-response workflow to minimize additional communication overhead.
