Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The blended fabric is segmented into its constituent fabric types (e.g., cotton, polyester), and the absorbance spectrum prediction is performed separately for each fabric type based on its specific dyeing characteristics. The individual predictions are then combined using blending ratios to produce the final prediction for the blended fabric, thereby maintaining accuracy while simplifying the overall process

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The method changes the prediction approach by introducing blending ratio as a key parameter that weights the absorbance spectrum contributions of different fabric types. Instead of treating the blended fabric as a homogeneous entity, the system adjusts the prediction based on the specific proportions of constituent fabrics, improving accuracy without significantly increasing process complexity

AI summary

An apparatus for predicting an absorbance spectrum of a blended fabric including a first fabric and a second fabric includes a memory that stores at least one command, and a processor that performs the at least one command stored in the memory, wherein the processor predicts a first absorbance spectrum, which is an absorbance spectrum for a first dye used for dyeing of the first fabric, predicts a second absorbance spectrum, which is an absorbance spectrum for a second dye used for dyeing of the second fabric, corrects the first and second absorbance spectra based on a blending ratio of the blended fabric, and predicts a third absorbance spectrum, which is an absorbance spectrum of the blended fabric, based on the corrected first and second absorbance spectra.
