Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods (simulation using CCM colorimetry system or AI model) are used to calculate dye mixing recipes, then the calculation process can be completed, but significant errors remain in the dye mixing recipe leading to color differences during field dyeing
Solution Approach 1:
The patent implements a feedback mechanism by measuring the actual absorbance of the mixed dye solution and comparing it with the target absorbance values. The system calculates correction values based on the differences between measured and target absorbance, then adjusts the dye mixing recipe accordingly. This closed-loop feedback process continuously refines the recipe accuracy until the color matches the target specification.
Solution Approach 2:
The patent changes the parameter approach from using simulated absorbance values to using actual measured absorbance values. By measuring the real absorbance characteristics of the mixed dye solution and using these empirical data to calculate correction values, the system transitions from theoretical prediction to experimental verification, significantly improving recipe accuracy and color reproduction reliability.
2Productivity
If dye mixing recipes are calculated through simulation, then the process can be completed efficiently, but scale-up issues and environmental factors cause color differences during field dyeing
Solution Approach 1:
The patent performs preliminary measurement of the actual absorbance characteristics of the mixed dye solution before finalizing the recipe. By measuring the real absorbance values and calculating correction values in advance, the system prepares adjusted recipe parameters that account for scale-up effects and environmental factors, ensuring color consistency when the dye is applied in field conditions.
Solution Approach 2:
The patent replaces the purely computational simulation approach with an experimental measurement approach. Instead of relying solely on computer simulations to predict dye behavior, the system uses actual spectroscopic measurements to characterize the mixed dye solution's absorbance properties, providing empirical data that accurately reflects real-world performance and enables precise recipe adjustment for field applications.
3Measurement precision
If absorbance data for electronic color value and monochromatic dyes are compared to calibrate the dye recipe, then color difference can be reduced, but the calibration process requires multiple measurement and calculation steps
Solution Approach 1:
The patent segments the calibration process into distinct sequential steps: (1) measuring absorbance of the mixed dye solution, (2) measuring absorbance of individual monochromatic dyes, (3) calculating correction values based on the differences, and (4) adjusting the dye mixing recipe. This segmentation breaks down the complex calibration task into manageable, systematic operations that can be performed in a structured manner using standard spectroscopic equipment.
