Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data streams from multiple sensors are synchronized with high precision, then the effectiveness of therapeutic parameter adaptation is improved, but the device complexity increases
Solution Approach 1:
A centralized server acts as an intermediary to receive, synchronize, and process data streams from multiple implantable sensors. The server performs temporal alignment using timestamps and corrects transmission delays, enabling coordinated therapeutic parameter adjustments without requiring complex synchronization logic in each implantable device.
Solution Approach 2:
The patent introduces a temporal dimension through precise timestamping of data streams from multiple sensors. By organizing data along the time axis and performing temporal alignment, the system achieves high-precision synchronization across distributed sensors, transforming a spatial distribution problem into a temporal processing solution.
2Loss of information
If multiple sensor data streams are collected and synchronized for comprehensive analysis, then the quality of data analysis is improved, but the loss of time in data transmission and processing increases
Solution Approach 1:
Timestamps are attached to data streams at the source (植入式传感器) before transmission, performing preliminary time-tagging action. This allows the server to synchronize and align data streams efficiently upon receipt without requiring complex real-time coordination during data collection, reducing overall processing time.
Solution Approach 2:
The system implements delay correction mechanisms where the server analyzes transmission delays from different sensors and applies compensatory time shifts to align data streams. This feedback-based delay correction ensures accurate temporal alignment while minimizing the time penalty associated with processing multiple data streams.
3Measurement precision
If implantable devices store and process large amounts of sensor data locally, then the measurement precision is improved, but the volume of data requiring transmission increases
Solution Approach 1:
The patent extracts the heavy computation and data storage functions from the implantable devices and relocates them to an external server. Implantable sensors perform only data acquisition and local timestamping, then transmit raw data streams to the server for comprehensive processing, storage, and analysis. This extraction reduces the computational burden and data volume requirements at the implantable site.
