Solution Overview
Problem
Conventional blood glucose detection modules using polarized light are bulky due to the need for a coil structure to generate an induced magnetic field for the Faraday rotator, making them unsuitable for miniaturization and wearable devices.
Innovation Solution
A miniaturized blood glucose measurement module incorporating an electromagnet assembly with a metal base and coil, combined with a light-emitting and light-receiving assembly that uses polarized light, where the electromagnet assembly directly drives the magnetic crystal to change the polarization angle, reducing module size and enhancing the Faraday effect for improved accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a coil structure is used to generate an induced magnetic field for the Faraday rotator, then the blood glucose detection can be performed, but the system becomes bulky and cannot be miniaturized
Solution Approach 1:
The patent merges the coil structure with the metal base to form an integrated electromagnet assembly. The coil is wound around the metal base, combining the magnetic field generation function with the structural support function, thereby reducing the overall module size while maintaining detection accuracy.
Solution Approach 2:
The metal base serves multiple functions: it provides structural support, acts as a mounting platform for the coil, and functions as part of the electromagnet assembly. This multi-functionality reduces the number of separate components needed, enabling miniaturization while preserving the Faraday rotator effect for accurate blood glucose detection.
2Volume of moving object
If the coil structure is integrated with the metal base, then the module is miniaturized, but the complexity of the electromagnet assembly increases
Solution Approach 1:
By integrating the coil with the metal base, the patent reduces the number of separate components and simplifies the overall structure. The coil is wound around the metal base, creating a compact electromagnet assembly that is easier to manufacture and integrate into the blood glucose detection module.
