Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If instrument analysis methods such as microscope spectroscopy and Raman spectroscopy are used for microplastic detection, then detection capability is provided, but detection sensitivity is low and real-time monitoring is difficult
Solution Approach 1:
The patent introduces monoclonal antibodies as intermediary substances that specifically bind to polystyrene microplastics. These antibodies serve as mediators between the microplastics and detection systems, enabling highly sensitive detection through immunological reactions rather than direct instrumental analysis of the microplastics themselves
Solution Approach 2:
The patent replaces complex instrumental analysis methods (microscope spectroscopy, Raman spectroscopy) with a biological detection system based on monoclonal antibody-antigen recognition. This substitution uses biochemical interactions instead of complex optical and mechanical instrumentation, simplifying the detection system while improving sensitivity
2Measurement precision
If existing polyclonal antibodies are used for microplastic detection, then some detection capability is achieved, but specificity and sensitivity are insufficient for rapid quantitative analysis
Solution Approach 1:
The patent transitions from using polyclonal antibodies (which are heterogeneous mixtures of multiple antibody types) to monoclonal antibodies (which are homogeneous and identical). This segmentation approach isolates a single, specific antibody clone that recognizes one particular epitope on polystyrene microplastics, thereby improving both specificity and sensitivity
Solution Approach 2:
The patent changes the fundamental parameter of antibody homogeneity by using monoclonal antibodies instead of polyclonal antibodies. This parameter change from heterogeneous to homogeneous antibody populations enables more consistent and reliable detection with higher sensitivity and specificity
3Productivity
If conventional detection technologies are used, then qualitative judgment is possible, but quantitative analysis and real-time monitoring are difficult
Solution Approach 1:
The patent employs immunochromatographic techniques that provide visual feedback through color changes proportional to the concentration of polystyrene microplastics. This feedback mechanism enables both qualitative and quantitative analysis, with the intensity of the color response directly correlating to the amount of target analyte present
Solution Approach 2:
The patent uses a step-wise immunochromatographic process with periodic actions (incubation, washing, detection) that enables rapid sequential operations. This periodic action format allows for quick completion of the detection cycle while maintaining quantitative accuracy through controlled timing of each step
