Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional continuous glucose monitoring systems require a fixed, predetermined stabilization time for sensor transmitters after insertion, which can lead to inaccurate data if the sensor is not fully stabilized, and prevent users from accessing biological information during this time.
Innovation Solution
A method to variably adjust the stabilization time for sensor transmitters based on the stability of the measured blood glucose data, allowing for dynamic adjustment of stabilization stages to ensure accurate and timely data output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed predetermined stabilization time is used for sensor transmitters, then the sensor can be stabilized before data output, but users cannot access biological information during this time and accurate data cannot be provided if the sensor stabilizes earlier
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed, uniform stabilization time to a variable stabilization time that adapts to each sensor transmitter's actual stabilization status. The system dynamically adjusts the stabilization duration based on real-time assessment of sensor performance metrics, allowing the stabilization period to be shorter when the sensor stabilizes quickly and longer when needed, thereby resolving the contradiction between ensuring measurement accuracy and minimizing time loss.
Solution Approach 2:
The patent implements feedback by continuously monitoring the sensor transmitter's output during the stabilization period and using this information to determine when stabilization is complete. The system assesses whether the biological information data meets predetermined accuracy criteria and adjusts the stabilization time accordingly, providing feedback loops that ensure measurement precision while avoiding unnecessary waiting time.
2Reliability
If a uniform predetermined stabilization time is applied to all sensor transmitters, then the system ensures consistent stabilization protocol, but sensors that stabilize earlier cannot provide data timely and sensors that require longer stabilization cannot achieve accurate measurements
Solution Approach 1:
The patent applies parameter changes by modifying the stabilization time parameter from a fixed uniform value to a variable value that adapts to each sensor transmitter's characteristics. The system changes the stabilization time parameter based on observed sensor performance, allowing the protocol to maintain reliability through systematic assessment while achieving adaptability to individual sensor variations in stabilization rates.
3Productivity
If the communication terminal displays biological information data during the stabilization period, then users can access information early, but inaccurate data is provided to the user
Solution Approach 1:
The patent uses feedback by monitoring the quality and stability of biological information data during the stabilization period and using this feedback to determine when it is appropriate to begin displaying data to users. The system assesses whether the data meets predetermined accuracy thresholds before releasing it for user access, ensuring both timeliness and precision by displaying data as soon as it becomes reliable.
