Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional incubation methods are used, then the incubation process can be performed, but the measurement of molecule attachment number and rate is inaccurate and limited
Solution Approach 1:
The patent replaces conventional biochemical measurement methods with magnetic measurement. Superparamagnetic nanoparticles conjugated to molecules (antibodies) allow detection through magnetic dipolar moment measurements, substituting complex biochemical assays with a more precise magnetic detection system that directly quantifies attachment number and rate.
Solution Approach 2:
The patent changes the physical state and properties of the detection system by using superparamagnetic nanoparticles with specific magnetic properties. The nanoparticles exhibit superparamagnetism at room temperature, allowing them to be manipulated and detected magnetically, providing a new parameter (magnetic dipolar moment) for measuring molecule-cell attachment that overcomes limitations of conventional methods.
2Loss of information
If conventional incubation methods are used, then the process can be completed, but the determination of antibody specificity and effectiveness is insufficient
Solution Approach 1:
The patent implements a feedback mechanism where magnetic dipolar moment measurements are taken at multiple time points during incubation. The attachment rate is determined by fitting the magnetic signal progression to a kinetic model, providing real-time feedback on the number and rate of molecule attachments. This enables accurate determination of antibody specificity and effectiveness for different cancer cell types.
