Solution Overview
Problem
Diabetes patients face a financial burden and inconvenience due to the need for a separate, expensive device to regularly measure blood glucose levels, which involves a complex and costly manufacturing process for strip modules.
Innovation Solution
A strip module integrated with a portable terminal using a dye pad that changes color in response to samples, coupled with a light source and camera, allowing for convenient and economic measurement of blood glucose levels without the need for a separate device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate blood glucose measuring device with a transparent film and punched hole is used, then blood glucose measurement function is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent extracts the essential measurement function from the complex existing system. Instead of using a dedicated measuring device with transparent films and punched holes, the invention uses only the dye pad portion that contains the blood sample, eliminating unnecessary structural elements while preserving the core measurement capability through colorimetric analysis
Solution Approach 2:
The portable terminal camera serves multiple functions: it captures images for blood glucose measurement, and the same camera can be used for other diagnostic purposes. The dye pad also serves dual purposes by changing color for both glucose detection and providing a visual reference for the camera to analyze, reducing the need for separate specialized components
2Measurement precision
If a separate blood glucose measuring device is used, then accurate blood glucose measurement is achieved, but economic burden on patients increases
Solution Approach 1:
The invention uses a disposable dye pad that is inexpensive to manufacture compared to traditional measuring devices. The dye pad is discarded after single use, eliminating the need for expensive reusable components while maintaining measurement accuracy through colorimetric analysis captured by the portable terminal camera
Solution Approach 2:
The portable terminal camera creates a digital copy of the dye pad color change, allowing the measurement function to be performed through image analysis rather than requiring specialized optical sensors. This copying approach significantly reduces manufacturing costs while preserving measurement precision
3Ease of operation
If a transparent strip with punched hole and transparent film is used, then sample measurement is enabled, but device complexity and cost increase
Solution Approach 1:
The invention extracts only the essential dye pad portion from the complex transparent strip structure with punched holes and films. The dye pad alone is sufficient for sample application and colorimetric measurement, eliminating unnecessary structural elements while maintaining ease of sample application
Solution Approach 2:
The dye pad is designed with localized color-changing properties at the specific region where blood is applied. This local quality change is captured by the camera, eliminating the need for extensive transparent films and punched holes while preserving the ease of sample application and measurement capability
