Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If offline analysis methods are used for molecular omics and cell morphology, then measurement precision is improved, but real-time dynamic observation capability deteriorates
Solution Approach 1:
The patent combines multiple detection modalities (fluorescence microscopy, phase contrast microscopy, and bright-field microscopy) into a single integrated observation system, enabling simultaneous acquisition of molecular dynamics and morphological changes in real-time, thus resolving the contradiction between measurement precision and real-time observation capability
Solution Approach 2:
The system implements continuous real-time imaging and monitoring of single cells throughout the entire experimental process, allowing uninterrupted observation of dynamic cellular responses to mechanical and biochemical stimuli, thereby eliminating the time loss associated with offline analysis
2Device complexity
If separate detection systems are used for mechanical signals and biochemical signals, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent designs a multi-functional integrated observation system that can simultaneously detect mechanical signal-induced cell deformation, biochemical factor concentration changes, and intracellular signaling molecule dynamics using a single platform, thereby achieving high-precision multi-parameter measurement without requiring multiple separate detection systems
Solution Approach 2:
The system segments different detection functions into distinct modular components (fluorescence detection module, phase contrast module, bright-field module) that work together in an integrated system, allowing each module to specialize in specific measurements while maintaining overall system coordination and precision
3Reliability
If traditional in vitro research systems are used, then interference factors are excluded, but dynamic interaction observation of intracellular signaling molecules deteriorates
Solution Approach 1:
The patent employs fluorescence labeling and colorimetric indicators to visualize intracellular signaling molecules and their dynamic interactions in real-time, enabling direct observation of molecular events within cells while maintaining the controlled in vitro environment, thus resolving the contradiction between experimental reliability and detection difficulty
