Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current gel microdrop screening methods are used, then the screening process can be performed, but the accuracy and reliability of identifying bioactive molecules is limited due to lack of efficient detection mechanisms
Solution Approach 1:
The patent employs reporter particles that emit distinct optically detectable signals (color changes) to indicate specific effects of antibodies. Different reporter particles emit different colors or optical signals, allowing accurate detection of antibody-specific effects on target particles without requiring complex analytical equipment.
2Reliability
If multiple reporter particles with distinct signals are used, then the specificity of antibody detection is improved, but the complexity of the composition increases
Solution Approach 1:
The patent divides the detection system into distinct reporter particles, each emitting a specific optically detectable signal. This segmentation allows independent detection of different antibody effects, improving reliability while maintaining manageable composition complexity through modular design.
Solution Approach 2:
The gel microdrop composition serves multiple functions: it encapsulates antibody-producing cells, contains multiple reporter particles for different detection purposes, and provides a controlled environment for screening. This multi-functionality improves detection reliability without proportionally increasing complexity.
3Measurement precision
If control reporter particles are included, then the accuracy of specific effect detection is enhanced, but the quantity of particles in the composition increases
Solution Approach 1:
Control reporter particles act as intermediaries to establish baseline responses and distinguish specific antibody effects from non-specific interactions. These control particles enable accurate detection by providing reference points for comparison, enhancing measurement precision with minimal additional quantity.
