Toy Identification Code Color Blending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optically readable identification codes on toys can compromise the appearance of the toy main body, especially when using two-dimensional codes like QR codes on colored surfaces, as they may alter the color scheme and design aesthetics.
Innovation Solution
A toy with an optically readable identification code that incorporates a data matrix two-dimensional code using a CMYK color model, where dark color portions are black and light color portions are cyan, magenta, or yellow, with a lower intensity than the dark colors, ensuring the code blends with the dominant color of the toy, thus minimizing visual impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional optically readable identification code (black and white portions) is provided on a colored toy surface, then the identification code can be read optically, but the appearance of the toy main body is compromised
Solution Approach 1:
The patent applies color changes by using chromatic colors (cyan, magenta, yellow) instead of conventional black and white colors in the identification code. The light color portions use chromatic colors with lower intensity than the dark color portions, allowing the code to blend with the colored toy surface while maintaining optical readability. This resolves the contradiction by changing the color palette to achieve both readability and aesthetic compatibility.
Solution Approach 2:
The patent applies parameter changes by adjusting the intensity parameter of the chromatic colors used in the light color portions. By using chromatic colors with lower intensity than the dark color portions, the identification code maintains sufficient contrast for optical reading while appearing more subtle and harmonious with the toy's overall color scheme, thus resolving the appearance compromise.
2Reliability
If the light color portions use high intensity chromatic colors, then the identification code is more readable, but the toy appearance is more compromised
Solution Approach 1:
The patent applies parameter changes by precisely controlling the intensity parameter of chromatic colors in the light color portions. The intensity is set to be lower than that of dark color portions but sufficient for optical readability. This optimization resolves the contradiction by finding the optimal intensity level that balances readability requirements with aesthetic considerations.

AI summary
A novel optically readable identification code and a toy with identification code with which a toy main body can be prevented from having the appearance compromised as much as possible are provided. A toy with identification code 10 includes a toy main body 11 with a surface provided with an identification code portion 12 including an optically readable identification code 13. The identification code 13 includes a plurality of dark color portions and a plurality of light color portions, and a chromatic color having an intensity lower than an intensity of a chromatic color used for the dark color portions is used for the light color portions.
