Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glucometers and pedometers do not effectively interact to correlate blood glucose levels with exertion levels, leading to inaccurate calorie expenditure measurements and lack of noise resistance, and there is a need for a cost-effective method to transmit data for real-time patient instructions.
Innovation Solution
A cellular-based Glucometer (CBG) system that uses a three-axis accelerometer pedometer to measure movement in any direction, correlating current from a blood-glucose strip with blood glucose levels, and transmits data over a cellular network for central monitoring and recommendation generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voltage is calculated directly from current flow in glucometers, then measurement simplicity is improved, but noise resistance deteriorates
Solution Approach 1:
The patent introduces an intermediary measurement approach by measuring impedance changes rather than directly calculating voltage from current. The glucometer measures impedance of the blood sample, and glucose concentration is determined from impedance changes over time, which are less susceptible to electrical noise interference.
Solution Approach 2:
The patent replaces the electrical measurement system (direct voltage calculation from current) with an impedance-based measurement system. This substitution uses electrical properties (impedance) that are inherently more resistant to noise while still providing accurate glucose concentration measurements.
2Ease of manufacture
If existing pedometers require particular orientation to differentiate axes, then manufacturing simplicity is improved, but measurement precision deteriorates
Solution Approach 1:
The patent transitions from 2D acceleration sensing (requiring specific orientation) to 3D acceleration sensing with three orthogonal axes. This dimensional expansion allows the device to accurately measure acceleration in any direction without requiring specific orientation, thereby improving measurement precision while maintaining manufacturing simplicity through standardized sensor integration.
Solution Approach 2:
The patent makes the pedometer universally applicable to any orientation by implementing three-axis acceleration sensing. The device can accurately measure steps and calorie expenditure regardless of how it is worn or positioned on the user's body, enhancing its multi-functional adaptability.
3Device complexity
If glucometers and pedometers operate independently, then device complexity is reduced, but information correlation capability deteriorates
Solution Approach 1:
The patent merges previously separate glucometer and pedometer functions into a single integrated system. The combined device simultaneously measures glucose concentration and physical activity, enabling real-time correlation between blood glucose levels and exertion levels to provide more accurate health monitoring and lifestyle recommendations.
Solution Approach 2:
The patent implements feedback mechanisms where data from both the glucometer and pedometer are continuously correlated and analyzed. The system uses this correlated information to provide feedback recommendations to users about optimal exercise timing, dietary adjustments, and insulin management based on the relationship between glucose levels and physical activity.

AI summary
The Cellular GPRS system includes a cellular-based Glucometer (CBG) for blood glucose monitoring, a pedometer for exertion measurement, combined with user-entered dietary or other diabetes-relevant information. Data from all inputs is transmitted over a cellular network, using a GPRS or other wireless link. The data is preferably stored in the device prior to being transmitted wirelessly over the cellular airway to a central computer server. The remote computer server will evaluate the data received and respond with a data packet (making recommendations on further glucose measurement, exercise, diet, insulin requirements or other).
