Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If established analytical methods such as nuclear magnetic resonance spectroscopy and infrared spectroscopy are used to determine the degree of hydrogenation, then measurement precision is improved, but loss of time and cost increase significantly
Solution Approach 1:
The patent replaces complex spectroscopic methods (nuclear magnetic resonance, infrared spectroscopy) with simple oscillation measurements using a vibration meter. This substitution of measurement principles dramatically reduces analysis time and cost while maintaining sufficient precision for process control applications. The oscillation frequency of a vibrating element changes with the density of the aqueous reaction system, which correlates to the degree of hydrogenation.
Solution Approach 2:
The patent utilizes changes in material properties (density, oscillation frequency) of the aqueous reaction system as the degree of hydrogenation changes. By measuring oscillation frequency at different hydrogenation states and establishing functional relationships, the system enables rapid determination of hydrogenation degree without time-consuming spectroscopic analysis.
2Measurement precision
If established analytical methods are used to determine the degree of hydrogenation, then measurement precision is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces expensive spectroscopic instrumentation with simple, low-cost oscillation measurement devices. The vibration meter used in the invention is significantly cheaper than nuclear magnetic resonance or infrared spectroscopy equipment, enabling cost-effective analysis suitable for industrial process control while maintaining adequate measurement precision.
Solution Approach 2:
The patent employs simple, inexpensive measurement devices (vibration meter, oscillation measurement setup) that can be easily manufactured or acquired, replacing expensive, complex spectroscopic instruments. This approach makes the analysis method accessible for routine industrial use without requiring expensive equipment investment.
3Device complexity
If simple measuring devices are used to determine concentration in multi-component systems, then device complexity is reduced, but measurement precision deteriorates due to inability to distinguish between multiple components
Solution Approach 1:
The patent measures multiple distinct material properties (density, electrical conductivity, oscillation frequency) of the aqueous reaction system and uses these segmented measurements to determine concentrations of different components (formate, bicarbonate, carbonate). By combining multiple simple measurements rather than relying on a single complex measurement, the system achieves precise component analysis using simple devices.
Solution Approach 2:
The patent transitions from single-dimension measurements to multi-dimensional characterization by measuring multiple material properties (density, conductivity, oscillation frequency). This multi-dimensional approach enables differentiation and quantification of multiple components in the reaction system using simple measurement devices, overcoming the limitation of single-property measurements.
