Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If indirect methods (mass spectroscopy, liquid chromatography) are used to measure enzyme activity, then measurement precision is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The patent uses fluorescent tags as intermediary molecules that bind to enzymes and emit detectable signals. This intermediary approach allows indirect measurement of enzyme activity through fluorescence intensity, avoiding the need for complex mass spectroscopy or chromatography systems while maintaining measurement capability
Solution Approach 2:
The patent replaces complex mechanical/chemical analysis systems (mass spectroscopy, liquid chromatography) with optical detection systems. By using fluorescent tags and microscopy, the measurement transitions from complex physical/chemical analysis to simpler optical signal detection, reducing device complexity
2Measurement precision
If indirect methods are used to determine enzyme activity, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
Fluorescent tags serve as intermediaries that simplify the measurement process. Instead of complex sample preparation and analysis procedures required by mass spectroscopy or chromatography, the fluorescent tags provide direct optical signals that can be detected through microscopy, making the procedure easier to perform
Solution Approach 2:
The patent utilizes fluorescence (optical property) changes as indicators of enzyme activity. The fluorescent tags emit light at specific wavelengths when bound to active enzymes, providing a simple visual/readable signal that simplifies operation compared to complex analytical procedures
3Measurement precision
If conventional methods are used to measure enzyme activity, then measurement precision is maintained, but productivity deteriorates due to inability to scale
Solution Approach 1:
The fluorescent tagging approach is universally applicable to multiple different enzymes. The same basic methodology (fluorescent tag attachment followed by microscopy detection) can be used across numerous enzyme types, enabling standardized high-throughput screening of multiple enzymes simultaneously without requiring different measurement protocols for each
Solution Approach 2:
The patent enables independent measurement of individual enzyme activities through specific fluorescent tagging of each enzyme of interest. This segmentation allows researchers to study multiple enzymes in parallel by tagging and detecting them separately, significantly increasing productivity compared to sequential analysis methods
