Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If physiological signals are transmitted via wired or wireless modules to cloud platforms for analysis, then the system can collect and store physiological data, but the user cannot obtain real-time feedback and must wait several hours to days for analysis results
Solution Approach 1:
The patent segments the feedback system into multiple transmission modes: local real-time feedback mode and remote feedback mode. The local mode provides immediate feedback without cloud dependency, while the remote mode enables long-distance communication. This segmentation resolves the contradiction by providing different feedback speed options for different usage scenarios.
Solution Approach 2:
The system dynamically switches between different signal transmission modes based on network conditions and user needs. The processing unit can select between local processing, cloud processing, or hybrid modes, allowing the system to adapt feedback time and system complexity dynamically rather than being fixed in one configuration.
2Ease of operation
If the system uses cloud platform transmission for physiological signal analysis, then remote access is enabled, but real-time feedback cannot be provided
Solution Approach 1:
The patent divides the feedback system into local and remote segments. The local segment handles real-time feedback requirements, while the remote segment provides cloud-based analysis. This allows the system to satisfy both remote access needs and real-time feedback requirements through different segments operating in parallel.
Solution Approach 2:
The patent introduces a local processing unit as an intermediary between the physiological signal source and the cloud platform. This intermediary can process signals locally for immediate feedback while also transmitting to the cloud for remote access, mediating between the conflicting requirements of real-time response and remote capability.
3Ease of operation
If the system transmits physiological signals over long distances to cloud servers, then remote feedback becomes possible, but data transmission time increases
Solution Approach 1:
The patent segments data transmission into two paths: local transmission for time-critical feedback and remote transmission for non-time-critical analysis. This segmentation allows the system to maintain fast local response while also providing remote access capability, resolving the speed-distance tradeoff.
Solution Approach 2:
The patent applies local quality by providing different transmission qualities for different destinations. Local transmissions receive high priority for speed, while remote cloud transmissions can tolerate longer delays. This differential quality approach resolves the contradiction between remote capability and transmission speed.

AI summary
Provided is a method for long-distance transmission of physiological signals in a closed loop system, including generating a signal at a user terminal of the closed loop system, compressing the signal to generate a compressed signal, transmitting the compressed signal from the user terminal to a computing terminal of the closed loop system, receiving and comparing the compressed signal with a database at the computing terminal to generate a comparison result and a feedback signal, and transmitting the feedback signal from the computing terminal to the user terminal. A time interval between generating the signal and receiving the feedback signal at the user terminal is less than a threshold.
