Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a lancet is used to collect blood for glucose measurement, then measurement accuracy is improved, but user pain and infection risk increase
Solution Approach 1:
The patent replaces the mechanical lancet-based blood collection system with an optical analysis system that uses light to measure glucose levels through the skin. The optical sensor module emits light that penetrates the skin and detects glucose concentration in the underlying tissue, eliminating the need for puncture and blood collection while maintaining measurement capability.
Solution Approach 2:
The patent introduces optical light as an intermediary medium to transfer information about glucose levels from the tissue to the sensor without requiring direct contact with blood. The light acts as a carrier that interacts with glucose molecules in the tissue and conveys this information to the detector, avoiding the harmful mechanical puncture process.
2Measurement precision
If a needle-type sensor is used to extract body fluid, then measurement accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces the complex mechanical needle-type sensor structure with an optical sensor system consisting of light sources, optical waveguides, and detectors. This substitution eliminates the need for precise micrometer-scale needle manufacturing while achieving comparable or superior measurement accuracy through optical interaction with tissue.
Solution Approach 2:
The patent creates an optical copy or representation of the glucose measurement process by using light to probe tissue composition without physically extracting fluid. The optical system captures information about glucose concentration through light-tissue interaction, providing a non-invasive alternative to physical fluid extraction.
3Ease of operation
If optical analysis method is used for blood sugar measurement, then user convenience is improved, but measurement accuracy decreases
Solution Approach 1:
The patent employs dynamic optical analysis by continuously varying the wavelength and intensity of light emitted into the tissue. The system dynamically adjusts measurement parameters and processes multiple wavelength signals to differentiate glucose absorption patterns from other tissue components, thereby improving accuracy while maintaining non-invasive operation.
Solution Approach 2:
The patent changes multiple optical parameters including wavelength, intensity, and polarization state of the emitted light to enhance measurement accuracy. By analyzing glucose absorption characteristics across different wavelengths and processing the spectral information, the system achieves accurate glucose measurement without compromising user convenience.
