Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an invasive sensor is inserted into the skin to measure blood sugar, then measurement accuracy is improved, but user comfort deteriorates due to pain and invasion
Solution Approach 1:
The patent replaces the mechanical invasive sensor with an electromagnetic wave-based measurement system. The measurement device emits electromagnetic waves through the skin to detect analyte concentration changes, eliminating the need for physical tissue insertion while maintaining measurement capability
Solution Approach 2:
The patent introduces electromagnetic waves as an intermediary medium to transfer measurement information through the skin. Instead of direct contact with blood, the system uses electromagnetic wave interaction with tissues and analytes as a mediator to obtain measurement data
2Object-affected harmful factors
If a non-invasive LED-photo diode method is used to measure blood sugar, then user comfort is improved, but measurement accuracy deteriorates due to environmental factors
Solution Approach 1:
The patent changes the measurement parameter from optical (LED-photo diode) to electromagnetic wave-based detection. By using electromagnetic waves with different frequencies and measuring their interaction with tissues and analytes, the system achieves better accuracy while maintaining non-invasive operation
Solution Approach 2:
The patent creates a multi-functional measurement system that can detect multiple analytes and provide both immediate measurements and trend data. The device combines electromagnetic wave emission, signal reception, and processing capabilities in a single integrated system
3Measurement precision
If frequent blood collection is performed to monitor disease, then measurement accuracy is improved, but user convenience deteriorates due to repeated pain and time loss
Solution Approach 1:
The patent enables continuous or frequent measurement without repeated blood collection. The electromagnetic wave-based system can perform multiple measurements sequentially, providing continuous monitoring data that eliminates the need for repeated invasive procedures
Solution Approach 2:
The measurement device performs autonomous measurement and data collection without requiring user intervention for blood collection. The system automatically emits electromagnetic waves, detects signals, and processes data, making the monitoring process convenient and pain-free
