Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to measure pungency of red pepper powder, then subjective assessment is possible, but objective and standardized measurement is not achieved
Solution Approach 1:
The patent replaces traditional subjective sensory assessment methods with a near-infrared spectral analysis system. The near-infrared sensor detects spectral characteristics of capsaicinoids in red pepper powder, and a recurrence model converts these spectral data into objective pungency measurements, eliminating human subjectivity while maintaining measurement accuracy.
Solution Approach 2:
The patent introduces a recurrence model as an intermediary between the near-infrared spectral data and the final pungency assessment. This model processes the complex spectral information and translates it into standardized pungency values, serving as a bridge between physical measurement and sensory evaluation.
2Productivity
If near infrared spectral analysis is applied to red pepper powder, then quick and non-destructive measurement is achieved, but preprocessing requirements and measurement accuracy challenges arise
Solution Approach 1:
The patent performs preliminary correction of the near-infrared spectrum using reference material data before conducting the actual pungency measurement. This preprocessing step adjusts for environmental factors and instrument variations, ensuring that the subsequent measurement is both rapid and accurate without requiring extensive sample preparation.
Solution Approach 2:
The patent employs a feedback mechanism where the measured spectrum is compared against reference spectra, and corrections are applied based on the deviation from expected patterns. This feedback loop ensures measurement precision while maintaining the speed advantage of near-infrared analysis.
3Ease of operation
If red pepper powder height is not equalized during measurement, then measurement process is simpler, but measurement accuracy decreases
Solution Approach 1:
The patent controls the physical parameter of powder height to ensure consistent measurement conditions. By equalizing the height of red pepper powder in the measurement cell, the system maintains reproducibility and accuracy without requiring complex sample preparation procedures, achieving a balance between operational simplicity and measurement precision.
