Engineering Contradiction Analysis
1Measurement precision
If traditional biosensors are used to measure biological sample properties, then measurement accuracy can be achieved, but costly equipment and complex pre-treatment are required
Solution Approach 1:
The patent replaces traditional complex biosensor systems with a simplified RF-based measurement system. Instead of using expensive biosensors that require complex pre-treatment, the invention uses radio frequency signals to directly measure biological sample properties through a sensing unit, substituting mechanical and chemical preparation steps with electromagnetic field-based detection
Solution Approach 2:
The patent changes the measurement parameter from traditional biosensor responses to RF signal characteristics (impedance, capacitance, inductance). By measuring changes in RF signal parameters when biological samples contact the sensing unit, the system achieves accurate measurement without requiring complex pre-treatment or expensive equipment
2Measurement precision
If traditional biosensor methods are used, then biological sample properties can be measured, but extensive pre-treatment is required
Solution Approach 1:
The patent eliminates the need for preliminary pre-treatment actions by designing a sensing unit that can directly detect biological samples in their native state. The RF-based detection method is inherently tolerant of sample variability, removing the need for complex preparation steps that would otherwise be required before measurement
Solution Approach 2:
The invention substitutes mechanical pre-treatment processes with RF signal-based detection. Instead of physically or chemically preparing samples before analysis, the system uses electromagnetic fields to directly probe sample properties, dramatically reducing preparation time and procedural complexity
