Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coating identification systems are inefficient, error-prone, and slow, often relying on brute force methods that consume significant processing time and resources, and are inflexible, making it difficult to accurately match target automotive coatings that include complex colorants and effect pigments.
Innovation Solution
A computerized system that processes spectrometric data through a probabilistic colorant analysis to identify potential colorants with high probabilities, which are then added to a formulation engine in order of decreasing probability to generate a coating formulation that matches the target coating within a predetermined threshold, utilizing parallel processing for rapid and accurate results.

Engineering Contradiction Analysis
1Measurement precision
If conventional brute force methods are used to identify target coating composition, then all available colorants can be searched, but processing time is excessive and system efficiency is low
Solution Approach 1:
The system performs preliminary action by using spectrometric data to pre-identify potential colorants present in the target coating before the formulation search begins. This preliminary identification narrows down the search space from all available colorants to only those likely present in the target, dramatically reducing processing time while maintaining identification accuracy.
Solution Approach 2:
The system segments the colorant identification process into distinct stages: (1) spectrometric data acquisition, (2) probabilistic colorant presence determination, and (3) formulation engine search. This segmentation allows each stage to be optimized independently, with the probabilistic analysis filtering candidates before the computationally intensive formulation search.
2Adaptability or versatility
If all available colorants are included in the formulation search, then complete coverage is achieved, but computational complexity and resource consumption increase
Solution Approach 1:
The system determines the presence or absence of each colorant in the target coating before initiating the formulation search. This preliminary determination creates a filtered subset of colorants that are actually present in the target, reducing the formulation engine's search space from all available colorants to only those relevant to the specific target coating.
Solution Approach 2:
The system applies partial action by including only those colorants that are determined to be present in the target coating, rather than exhaustively searching all available colorants. This selective approach reduces computational complexity while maintaining sufficient versatility to achieve accurate color matching.
3Measurement precision
If conventional coating identification systems are used, then basic color matching can be achieved, but accuracy is insufficient for complex automotive coatings with effect pigments
Solution Approach 1:
The system changes the parameter of colorant identification from simple spectral comparison to probabilistic presence determination based on spectrometric data. This parameter change enables the system to handle complex automotive coatings with effect pigments like aluminum flakes by determining whether each colorant is present or absent, rather than attempting to directly match complex spectral signatures.
Solution Approach 2:
The system introduces an intermediary step between spectrometric data acquisition and formulation search: the probabilistic colorant presence determination. This intermediary analysis acts as a mediator that translates complex spectrometric data into a simplified presence/absence profile of colorants, which then guides the formulation engine to achieve accurate color matching.

AI summary
A computer system for seeding a formulation engine receives spectrometric data from a target coating. The computer system processes the spectrometric data through a probabilistic colorant analysis. The probabilistic colorant analysis generates a set of colorants. Each colorant within the set of colorants is associated with a calculated probability that the associated colorant is present within the target coating. Additionally, the computer system adds at least a portion of the colorants within the set of colorants to a formulation engine. The portion of the colorants is added to the formulation engine in order of decreasing probability. Further, the computer system generates, from an output of the formulation engine, a coating formulation that is calculated to match the target coating within a predetermined qualitative threshold.
