Solution Overview
Problem
Two-dimensional color codes, which enhance information storage by using color transitions, face slow recognition processing due to sequential processing rather than concurrent recognition of information.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If two-dimensional color codes use multiple colors and color transitions to increase information storage, then information amount per unit area is improved, but recognition processing speed deteriorates due to sequential processing requirements
Solution Approach 1:
The optically-readable symbol is divided into multiple independent cell lines (first cell line with plurality of first cells, and multiple second cell lines with second cells). Each cell line can be recognized independently and concurrently, enabling parallel processing while maintaining high information density through the multi-color encoding scheme.
2Reliability
If color transitions between adjacent segments are used to enhance distortion durability, then reliability is improved, but recognition processing complexity increases
Solution Approach 1:
By segmenting the code into multiple cell lines with distinct spatial arrangements, the patent reduces recognition complexity. Each cell line can be processed independently, and the connection relationships between cells provide robustness against distortion without requiring complex global analysis of color transitions.
Solution Approach 2:
The patent applies different encoding structures to different parts of the symbol. The first cell line and second cell lines have specific connection relationships that provide local redundancy and distortion resistance, while allowing efficient local processing rather than requiring analysis of the entire symbol structure.
