Solution Overview
Problem
Existing blood glucose management systems face challenges in accurately synchronizing time data between dosing devices and blood glucose measuring devices, leading to errors in historical monitoring and treatment optimization, particularly due to deviations in clock precision and user adjustments.
Innovation Solution
A blood glucose system that utilizes a dosing device with an integrated time counter generating relative time values and a blood glucose measuring device with an integrated time standard, where the data processing unit converts relative time values into absolute time values using the time standard, eliminating the need for precise clocks in the dosing device and simplifying user operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an integrated time standard (clock) is implemented in the dosing device, then time synchronization accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the time standard function from the dosing device and relocates it to the data processing apparatus. The dosing device only retains a simple time counter for recording relative time values, while the data processing apparatus contains the integrated time standard (clock) that provides accurate absolute time values for synchronization.
Solution Approach 2:
The patent introduces a communication interface as an intermediary between the dosing device and data processing apparatus. This interface enables the transfer of time data and allows the data processing apparatus to synchronize time with the dosing device without requiring the dosing device to have its own complex time standard.
2Adaptability or versatility
If user-adjustable clocks are provided in the dosing device, then adaptability to different time zones is improved, but reliability of time synchronization deteriorates
Solution Approach 1:
The patent removes the user-adjustable clock function from the dosing device and places time zone adaptation capabilities in the data processing apparatus. The dosing device maintains a fixed time counter that records relative time values without user adjustment, ensuring consistent and reliable time synchronization.
Solution Approach 2:
The data processing apparatus is designed with multi-functionality to handle different time zones and date formats. It can receive time data from the dosing device, adjust for time zone differences, and present the data in the appropriate time format without requiring changes to the dosing device itself.
3Measurement precision
If precise clocks with high running precision are installed in the dosing device, then measurement precision of time values is improved, but manufacturing cost increases
Solution Approach 1:
The patent extracts the expensive precise clock from the dosing device and relocates it to the data processing apparatus. The dosing device only requires a simple, inexpensive time counter that can record relative time values, significantly reducing manufacturing costs while maintaining sufficient precision for the intended application.
Solution Approach 2:
The patent uses a simple time counter in the dosing device that does not require high precision or expensive components. This basic time recording mechanism is sufficient for the application, and the more expensive precise clock is only needed in the data processing apparatus where it can be shared across multiple devices.
