Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If rheometer or cryogenic transmission electron microscope is used to detect wormlike micelles, then detection accuracy is improved, but device cost and complexity increase
Solution Approach 1:
The patent employs fluorescent probes with short excitation wavelengths that can be easily replaced and are cost-effective. These probes undergo photobleaching after use, similar to disposable objects, but can be regenerated or replaced at low cost, eliminating the need for expensive reusable instrumentation like rheometers or cryo-TEM
Solution Approach 2:
The patent replaces mechanical measurement systems (rheometer for viscosity measurements, cryo-TEM for direct imaging) with an optical detection system using fluorescent probes and fluorescence spectroscopy. This substitution eliminates complex mechanical instrumentation while maintaining detection capability through chemical-fluorescent interaction
