2D Barcode with Colored Square Portions for Curved Surface Normalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 2D barcodes struggle with normalization when applied to curved or irregular surfaces, leading to distortion and missed information, which is a challenge for industries relying on accurate data transmission.
Innovation Solution
The creation of a 2D barcode with an array of squares, where at least one square includes portions defined by diagonal lines and additional shape-based identifiers, incorporating distinct color segments to enhance reading accuracy and correct distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional 2D barcodes are applied to curved or irregular surfaces, then the barcode can be displayed on diverse surfaces, but distortion occurs and information may be missed during normalization
Solution Approach 1:
The patent applies color changes by introducing multiple color portions (first color portion, second color portion, third color portion) within each square of the barcode. These different color segments enable the scanning device to distinguish between various parts of the square and accurately identify geometric features even when the barcode is distorted on curved surfaces, thereby maintaining normalization accuracy while adapting to diverse surfaces.
2Measurement precision
If squares in the 2D barcode include additional shape-based identifiers and color segments, then reading accuracy and distortion correction improve, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing each square into multiple distinct color portions (first color portion, second color portion, third color portion) with specific geometric relationships. This segmentation allows the scanning device to independently analyze each portion and accurately determine the square's geometric features even when distorted, thereby improving reading accuracy while managing complexity through systematic division.
Solution Approach 2:
The patent applies local quality by assigning different color characteristics to different portions of each square. The first color portion, second color portion, and third color portion each have distinct color properties that provide localized information about the square's geometry. This local differentiation enables precise measurement of geometric features without requiring the entire barcode structure to be overly complex.
