Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional detection methods are used, then detection can be performed, but analytes present in low concentrations cannot be detected and signal-to-noise ratios are insufficient
Solution Approach 1:
The detection system is segmented into multiple polymer pairs, each specific for a different analyte. Each polymer pair operates independently to detect its target analyte, allowing parallel detection of multiple analytes simultaneously. This segmentation enables sensitive detection of low-concentration analytes by distributing the detection load across multiple independent detection channels, each optimized for its specific analyte.
Solution Approach 2:
The patent introduces a conformational dimension to the detection process. Polymers transition from linear forms to complex forms upon analyte binding, creating a detectable dimensional change. This conformational transition provides an additional detection dimension beyond simple concentration measurement, enabling differentiation between bound and unbound states and improving signal-to-noise ratios.
2Adaptability or versatility
If multiple analytes are detected simultaneously, then profiling of conditions is enabled, but detection complexity increases
Solution Approach 1:
The detection system is divided into multiple polymer pairs, with each pair specific for a different analyte. This segmentation allows simultaneous detection of multiple analytes in parallel, enabling condition profiling without requiring complex sequential analysis. Each polymer pair operates independently, simplifying the overall assay design while maintaining multiplexed capability.
Solution Approach 2:
The polymer pair system provides universal applicability across different analytes. The same basic detection mechanism (polymer conformational change) is used for all analytes, from proteins to nucleic acids. This multi-functionality reduces the need for analyte-specific detection methods, simplifying the overall system while enabling broad spectrum analysis.
3Measurement precision
If polymer pairs are used to form complexes, then signal-to-noise ratios improve, but manufacturing complexity increases
Solution Approach 1:
The analyte itself serves as an intermediary that mediates the formation of polymer complexes. When the analyte is present, it binds to multiple polymer pairs simultaneously, facilitating complex formation. This intermediary mechanism simplifies the manufacturing process by eliminating the need for complex in-silico design and testing, as the analyte-driven complex formation occurs naturally during the detection process.
