Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electrochemical measurement methods (glucose oxidase electrode or glucose dehydrogenase electrode) are used, then blood glucose values can be obtained through test strips, but the test strips are not easy to preserve, easily deteriorate due to preservation environment influence, and require invasive blood sampling
Solution Approach 1:
The patent replaces the electrochemical measurement system with an optical measurement system. Instead of using electrochemical reactions between test strips and blood glucose, the invention uses light sources to illuminate the measurement area and optical sensors to detect light absorption or scattering changes that correlate with glucose concentration. This substitution eliminates the need for test strips and their associated preservation issues, while maintaining measurement capability through a different physical principle.
2Measurement precision
If invasive blood sampling is performed using blood sampling needles, then blood glucose can be measured, but the needles can only be used once and need to be discarded, resulting in resource waste
Solution Approach 1:
The patent replaces the mechanical invasive sampling system with a non-invasive optical measurement system. Instead of using needles to extract blood samples, the invention uses light to probe the measurement area (likely through tissue or fluid) and detect glucose concentration optically. This eliminates the need for disposable needles and blood collection, thereby preventing resource waste while achieving the same measurement objective.
3Measurement precision
If phase modulator groups with 180° phase difference are used in blood glucose spectrum testing, then testing can be performed, but phase difference adjustment is required and the optical path structure becomes complicated
Solution Approach 1:
The patent extracts and removes the complex phase modulator groups from the optical measurement system. Instead of using multiple light sources with phase modulators requiring 180° phase difference adjustment, the invention employs a simplified optical path that achieves blood glucose spectrum testing without these complex components. This extraction of unnecessary elements directly reduces device complexity while preserving the core measurement function.
