Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional detection methods are used for inflammatory biomarkers, then detection can be performed, but the detection speed is slow and cannot provide timely results for rapid intervention
Solution Approach 1:
The patent replaces conventional mechanical/chemical detection methods with electrochemical detection. The electrochemical sensor uses electron transfer reactions between the biomarker and electrode, enabling rapid detection within minutes compared to hours or days required by conventional methods. This substitution of detection mechanism directly addresses the speed-time contradiction.
Solution Approach 2:
The patent changes the detection parameter from conventional biochemical assays to electrochemical signals. By measuring electrical current or impedance changes when biomarkers bind to functionalized electrodes, the system achieves rapid real-time detection. This parameter change enables continuous monitoring and fast results critical for timely intervention in cytokine storms.
2Measurement precision
If conventional detection methods are used, then detection can be performed, but the accuracy and sensitivity for early detection of cytokine storms is insufficient
Solution Approach 1:
The patent substitutes conventional detection with electrochemical detection that offers superior sensitivity. The electrochemical method can detect biomarkers at very low concentrations through amplified electron transfer signals, providing accurate early detection of cytokine storms before clinical symptoms manifest, thereby improving both measurement precision and reliability.
Solution Approach 2:
The patent introduces molecular recognition probes (antibodies, aptamers) as intermediaries between the biomarker and electrode. These probes specifically bind to target biomarkers like IL-6 and CRP, concentrating them on the electrode surface and amplifying the detection signal. This intermediary mechanism enhances both accuracy and reliability for early detection.
3Adaptability or versatility
If comprehensive detection of multiple biomarkers is implemented, then complete diagnostic information is obtained, but the device complexity increases
Solution Approach 1:
The patent divides the detection system into multiple independent electrochemical sensor channels, each functionalized with specific molecular probes for different biomarkers (IL-6, CRP, ferritin, etc.). This segmentation allows simultaneous detection of multiple biomarkers through parallel electrochemical measurements, achieving comprehensive diagnostics without requiring a single complex monolithic device.
Solution Approach 2:
The patent creates a universal electrochemical sensor platform that can detect multiple different biomarkers using the same basic electrochemical cell design. By functionalizing electrodes with different molecular recognition elements, the same device structure serves multiple detection functions, reducing overall system complexity while maintaining versatility.
