Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If irreversible analysis methods such as inverse Laplace transform are used to calculate diffusion coefficients and reaction states, then measurement precision is improved, but analysis time and computational complexity increase significantly
Solution Approach 1:
The patent applies periodic action by cyclically changing the flow rate or fluid pressure of the introduction target fluid in a periodic manner. This periodic modulation transforms the analysis from requiring complex irreversible methods to using frequency analysis, which can be performed more efficiently. The periodic flow rate changes create corresponding periodic variations in the discharged fluid composition that can be analyzed through frequency domain methods.
Solution Approach 2:
The patent substitutes the mechanical/computational process of irreversible analysis (inverse Laplace transform) with frequency analysis methods. By transforming the time-domain problem into the frequency domain through periodic excitation, the complex computational mechanics of irreversible analysis are replaced with more efficient spectral analysis techniques that yield the same measurement precision with reduced computational burden and time.
2Measurement precision
If irreversible analysis routines based on exponential response are used to analyze the state inside the flow reactor, then analysis accuracy is improved, but device complexity and computational requirements increase
Solution Approach 1:
By implementing periodic changes in flow rate or pressure, the system transforms the analysis approach from requiring complex irreversible analysis routines to using frequency analysis. This periodic excitation method simplifies the analytical framework while maintaining accuracy, as frequency domain analysis is more straightforward to implement and interpret than time-domain irreversible analysis.
Solution Approach 2:
The patent changes the operational parameters by cyclically modulating the flow rate or fluid pressure. This parameter change strategy transforms the system's response characteristics, enabling the use of frequency analysis instead of complex irreversible analysis routines. The periodic parameter modulation creates a system response that is more amenable to simplified analytical methods while preserving the accuracy needed for flow reactor state analysis.
