Color Measurement Data Comparison for Component Boundary Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for comparing colors of components in assembly manufacturing are subjective and lack a quantified approach, leading to potential visual recognition of color differences at boundaries between components.
Innovation Solution
A color measurement data processing device and system that enables quantified comparison of colors between first and second components via a networked system, allowing component manufacturers to measure and compare colors independently, with an assembly manufacturer performing the final comparison.

Engineering Contradiction Analysis
1Ease of operation
If visual comparison method is used to compare colors of components, then the comparison process is simple, but the comparison result is subjective and may lead to visual recognition of color differences at boundaries
Solution Approach 1:
The patent replaces the mechanical/visual comparison method with an optical measurement system. Colorimeters or spectrophotometers objectively measure color values (L*a*b* coordinates) of components, converting subjective visual assessment into quantifiable data that can be precisely compared and analyzed.
Solution Approach 2:
The patent introduces color measurement data as an intermediary between the components and the comparison process. Instead of directly comparing visual appearances, the system measures and compares colorimetric parameters (L*, a*, b* values), providing an objective basis for determining color compatibility at boundaries.
2Measurement precision
If assembly manufacturer conducts visual comparison between colors of first and second components, then the comparison can be performed, but the burden on assembly manufacturer increases and efficiency decreases
Solution Approach 1:
The patent implements preliminary color measurement and evaluation by component manufacturers before components are supplied to the assembly manufacturer. Color compatibility is assessed in advance, and only components meeting color specifications are supplied, eliminating the need for time-consuming comparisons at the assembly stage.
Solution Approach 2:
The patent divides the color comparison task into separate segments: component manufacturers perform color measurement and self-evaluation of their components, while the assembly manufacturer receives pre-evaluated components. This segmentation distributes the workload and improves overall manufacturing efficiency.
3Productivity
If component manufacturers measure colors independently and provide data to assembly manufacturer, then the burden on assembly manufacturer is reduced, but the system complexity increases
Solution Approach 1:
The patent employs universal color measurement standards (CIE L*a*b* color space) and common instrumentation that can be used by any component manufacturer. The same measurement principles and data formats apply across different manufacturers and component types, simplifying the overall system despite multiple independent measurements.
Solution Approach 2:
The patent transforms color information into standardized parametric form (L*, a*, b* coordinates) that can be easily transmitted, stored, and compared. This parameter transformation simplifies data exchange between component manufacturers and the assembly manufacturer, reducing system complexity.

AI summary
A color measurement data receiving section (45) receives, via the Internet (3), first color measurement data representing a color exhibited by a first component constituting a product, and second color measurement data representing a color exhibited by a second component different from the first component and constituting the product. A comparative data generation section (47) generates comparative data capable of enabling the color exhibited by the first component and the color exhibited by the second component to be compared with each other, using the first color measurement data and the second color measurement data received by the color measurement data receiving section (45).
