Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional generalized analysis techniques are used to determine cannabinoid concentration, then the analysis can be performed on a wide variety of chemical samples, but the process is wasteful, involves extraneous equipment, and requires a trained expert
Solution Approach 1:
The system segments the analysis process into specific modules: a solvent input port for targeted solvent delivery, an extraction cartridge configured for cannabinoid-specific extraction, and a spectroscopy cell for focused detection. This segmentation allows the system to handle diverse samples while maintaining simplicity for cannabinoid analysis.
Solution Approach 2:
The extraction cartridge is designed to selectively extract cannabinoids from the chemical mixture, separating them from other components. This extraction step removes unnecessary substances before analysis, simplifying the detection process and eliminating the need for complex separation equipment.
2Adaptability or versatility
If conventional generalized analysis techniques are used, then various chemical samples can be analyzed, but the process is needlessly wasteful and involves extraneous equipment
Solution Approach 1:
The system uses local quality by implementing cannabinoid-specific detection parameters in the spectroscopy cell. Rather than using broad-spectrum analysis that wastes resources detecting irrelevant substances, the system focuses detection capabilities specifically on cannabinoid signatures, reducing waste while maintaining versatility.
Solution Approach 2:
The extraction cartridge performs partial separation of cannabinoids from the chemical mixture, focusing only on the components of interest. This partial action approach avoids the waste associated with complete separation of all components, achieving efficient analysis with reduced solvent and sample consumption.
3Measurement precision
If conventional generalized analysis techniques are used, then comprehensive chemical analysis can be performed, but a trained expert in chemical analysis is required
Solution Approach 1:
The system incorporates automated features including a pump that automatically delivers precise solvent volumes, an extraction cartridge that performs self-contained separation, and a controller that automatically processes spectroscopy data. This self-service automation eliminates the need for expert manual intervention while maintaining high measurement precision.
Solution Approach 2:
The spectroscopy cell uses specific wavelength parameters (UV at 230 nm and IR at 3000 nm) that are optimized for cannabinoid detection. These parameter changes from conventional broad-spectrum analysis enable automated, expert-free operation while maintaining accurate measurement through targeted detection.
4Quantity of substance
If conventional analysis methods are used, then general chemical composition can be determined, but the process lacks specificity for cannabinoids of interest
Solution Approach 1:
The extraction cartridge performs preliminary extraction of cannabinoids from the chemical mixture before spectroscopy analysis. This preliminary action concentrates the cannabinoids of interest and removes interfering substances, enabling highly precise concentration measurements that general analysis methods cannot achieve.
Solution Approach 2:
The extraction cartridge acts as an intermediary between the chemical mixture and the spectroscopy cell. It selectively isolates cannabinoids and presents them in an optimized state for detection, improving measurement precision while still providing comprehensive quantity data for analysis.
