Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-performance liquid chromatography is used to establish a fingerprint method for traditional Chinese medicine compounds, then the quality control and identification accuracy are improved, but the device complexity and measurement process complexity increase
Solution Approach 1:
The complex multi-component traditional Chinese medicine compound is segmented into individual chemical components that can be separately identified and quantified through HPLC fingerprinting. Each component has a characteristic retention time and peak area that contributes to the overall fingerprint profile, enabling precise identification without requiring complex analysis of the entire mixture.
Solution Approach 2:
The HPLC system acts as an intermediary between the complex traditional Chinese medicine compound and the detection system. By using chromatographic separation as an intermediary process, the method simplifies the analysis of complex mixtures into resolvable individual components, improving identification accuracy while managing device complexity through standardized HPLC instrumentation.
2Reliability
If comprehensive quality control methods are implemented for traditional Chinese medicine compounds, then the product quality and consistency are improved, but the manufacturing process complexity and time increase
Solution Approach 1:
The fingerprint method establishes baseline chromatographic profiles of reference standard compounds before actual quality control testing. These pre-established fingerprints serve as reference standards that enable rapid comparison and identification during production, improving product quality consistency without requiring complex real-time analysis procedures.
Solution Approach 2:
The method creates a chromatic fingerprint profile (a type of data copy) of the traditional Chinese medicine compound that can be stored and compared against reference standards. This fingerprint copy contains characteristic peak patterns that identify the compound's composition, enabling quality control through pattern matching rather than complex analytical procedures.
3Loss of information
If multiple chemical components are analyzed in traditional Chinese medicine compounds, then the comprehensive quality information is improved, but the measurement time and analysis duration increase
Solution Approach 1:
The HPLC fingerprint analysis continuously detects multiple chemical components simultaneously as they elute from the chromatographic column. The system continuously records peak areas, retention times, and intensity values for all components in a single continuous run, maximizing the quality information obtained per unit of measurement time through uninterrupted analytical action.
