Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional invasive glucometer methods are used, then blood glucose levels can be measured, but the method causes discomfort, pain, and requires single-use test strips leading to financial burden
Solution Approach 1:
The patent replaces the mechanical invasive blood extraction system with an electromagnetic field-based measurement system. The device uses electromagnetic waves to interact with glucose molecules in the body, detecting their rotational motion and resonance frequencies to determine glucose concentration without physical contact or blood extraction, thereby eliminating discomfort and pain while maintaining measurement capability
Solution Approach 2:
The patent introduces electromagnetic waves as an intermediary medium to measure glucose levels. Instead of directly extracting and analyzing blood, the system uses electromagnetic fields that can penetrate tissue and interact with glucose molecules, allowing indirect measurement of blood glucose levels through the electromagnetic response of glucose in the body
2Measurement precision
If conventional glucometer methods are used, then blood glucose levels can be measured, but continuous real-time monitoring is not provided
Solution Approach 1:
The patent enables continuous real-time monitoring by maintaining a continuous electromagnetic field that constantly interacts with glucose molecules in the body. The system continuously detects changes in the electromagnetic response caused by glucose rotation and resonance, providing uninterrupted real-time glucose level data rather than discrete periodic measurements
Solution Approach 2:
The patent utilizes the periodic rotational motion and resonance frequencies of glucose molecules as natural oscillating actions. By detecting these periodic electromagnetic responses at specific resonance frequencies, the system can continuously track glucose levels through the rhythmic molecular behavior of glucose in the body
3Measurement precision
If invasive blood sampling is performed, then accurate blood glucose levels can be obtained, but the method carries risk of infection and requires clinical settings
Solution Approach 1:
The patent replaces the invasive mechanical blood sampling process with a non-contact electromagnetic measurement system. By using electromagnetic waves to detect glucose molecular rotation and resonance, the system eliminates the need for needle punctures, blood extraction, and laboratory analysis, thereby removing infection risks and enabling use in non-clinical settings while preserving measurement accuracy
Solution Approach 2:
The patent enables the body's own glucose molecules to serve as the measurement target directly in their natural physiological environment. The glucose molecules themselves provide the electromagnetic signal through their rotational motion and resonance, eliminating the need to extract blood samples for external analysis and allowing measurement in the natural biological context without contamination or infection risk

AI summary
The present invention discloses a state-of-the-art non-invasive blood glucose monitoring system powered by radio frequency (RF) signals to determine glucose levels in the blood. The system consists of a sensor plate, which functions as an antenna, transmitting RF signals through the body and analyzing the reflection coefficient to detect changes in blood glucose concentration. A Voltage Standing Wave Ratio (VSWR) meter is integrated with the device to measure the reflection of the RF signal, which is indicative of the body's impedance mismatch due to glucose variations. The system incorporates a microcontroller, which processes the forward and reverse voltage signals obtained from the VSWR meter to calculate the reflection coefficient. In addition, a Bluetooth system is included for wireless data transmission to a secondary device, such as a smartphone or PC, where a specialized software application processes the VSWR data to estimate the blood glucose level through quadratic interpolation. The efficacy of the system is validated against standard glucometer readings, demonstrating its potential as a convenient and pain-free alternative for diabetes management and monitoring. The device's architecture and its components are designed to ensure user-friendly operation, precise measurements, and seamless integration into the user's lifestyle.
