Color Harmonization Tolerances for Visually Accepted Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for color harmonization in manufacturing, such as Poland's patent application, fail to account for visual examinations and do not adjust manufacturing parameters based on visual acceptance, leading to labor and machinery inefficiencies, delays, and customer dissatisfaction due to color inconsistencies.
Innovation Solution
An automated method for color harmonization that uses algorithms and visual examination to establish numerical-visual color tolerances, adjusting manufacturing parameters and process variables to ensure client acceptance, incorporating both numerical and visual measurements to manage color variations and improve tolerance definition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If empirical color testing and manual optimization processes are used, then color specifications can be achieved through trial and error, but labor and machinery costs increase, delivery times are delayed, and customer satisfaction decreases
Solution Approach 1:
The patent replaces manual visual inspection and empirical trial-and-error processes with automated optical measurement systems (spectrophotometers, colorimeters) and computer-based algorithms. This substitution enables precise color measurement and automated analysis, eliminating the need for manual optimization while maintaining or improving color accuracy.
Solution Approach 2:
The system enables self-service through automated color measurement, data analysis, and process optimization. The computer automatically processes color data from multiple parts, compares measurements against specifications, identifies deviations, and suggests corrections without requiring manual intervention from operators or extensive interdepartmental coordination.
2Reliability
If multiple color tests and interdepartmental coordination are performed, then color specifications can be validated, but labor costs and operational complexity increase
Solution Approach 1:
The patent creates a universal color management system that can handle multiple functions: measuring color of different parts, storing specifications, analyzing deviations, generating reports, and suggesting corrections. This single integrated system replaces multiple separate testing procedures and coordination efforts across different departments, reducing organizational complexity while maintaining validation reliability.
3Measurement precision
If traditional color measurement devices are used without considering texture variations and base substrate, then color can be measured at a point, but visual examination accuracy decreases due to disparate measurements
Solution Approach 1:
The patent applies local quality by making the measurement process aware of and adaptive to local characteristics of the part being measured. The system considers texture variations and base substrate differences when analyzing color data, allowing accurate color assessment that accounts for local part-specific features rather than treating all surfaces uniformly.

AI summary
The invention relates to a method for the harmonization of color in manufactured items, which allows color tolerances to be established based on pre-defined values and visual observations for the different parts that form the item and the operating conditions for the manufacture of said parts by which means the colors falling within said tolerances can be obtained as well as the acceptance of the color harmonization of the final product by means of the use of algorithms and visual examination by a person or a machine.
