Solution Overview
Problem
Conventional glucose monitoring methods for diabetes patients, such as SMBG, are inconvenient and infrequent, leading to delayed detection of hyperglycemic or hypoglycemic conditions, and continuous glucose monitoring systems are cumbersome and require uncomfortable finger pricking.
Innovation Solution
A system featuring a pre-connected analyte sensor with a sensor carrier that facilitates temporary and permanent electrical connections, includes an identifier, and is designed for easy integration with manufacturing and wearable devices, enabling efficient handling and data tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional SMBG methods are used, then device complexity is reduced, but measurement frequency and reliability deteriorate due to infrequent monitoring
Solution Approach 1:
The monitoring system is segmented into a simple wearable sensor component and a separate processing/display device, allowing continuous monitoring without requiring complex integrated systems. The sensor can be used standalone with basic functionality.
Solution Approach 2:
A receiver device acts as an intermediary between the simple sensor and the user, handling complex data processing, calibration, and display functions externally while keeping the wearable sensor itself simple and comfortable.
2Measurement precision
If continuous monitoring is implemented, then measurement precision is improved, but ease of operation deteriorates due to uncomfortable finger pricking
Solution Approach 1:
The painful finger pricking function is extracted and replaced with an alternative sampling method. The sensor obtains glucose measurements through non-invasive or minimally invasive means such as interstitial fluid sampling, eliminating the need for repeated finger pricks while maintaining continuous monitoring capability.
3Manufacturing precision
If sensor carrier with permanent connections is used, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
Electrical connections are pre-established between the sensor electrodes and the carrier contacts during sensor fabrication. This preliminary action ensures precise alignment and reliable electrical connectivity before the sensor is assembled into the final device, simplifying the overall assembly process.
4Ease of manufacture
If temporary mechanical connections are used during manufacturing, then ease of manufacture is improved, but reliability deteriorates due to alignment inaccuracies
Solution Approach 1:
The sensor is pre-assembled with its electrical connections established to the carrier before integration into the monitoring system. This preliminary assembly ensures reliable electrical connectivity is achieved before final device assembly, maintaining both manufacturing ease and connection reliability.
