Two-Dimensional Symbol Second Modules Color Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In two-dimensional symbols like QR codes, it is challenging to ensure easy color identification between center and outer peripheral modules, leading to difficulties in distinguishing between easily identifiable and harder-to-identify colors, which affects data recording and reading efficiency.
Innovation Solution
The introduction of second modules placed between first modules, allowing for greater freedom in size and shape, enabling easier color identification and equalizing the recording capacities and ease of identification between first and second data areas, while using error correction codes and encryption for enhanced data security and authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If modules are divided into center portions and outer peripheral portions to record two types of data, then additional data can be recorded, but it becomes difficult to make sizes and shapes of the center portion and outer peripheral portion resemble each other, leading to difficulty in color identification
Solution Approach 1:
The patent divides the two-dimensional symbol into two independent module systems: first modules arranged vertically and horizontally for primary data, and second modules placed in intermediate points between adjacent first modules for additional data. This segmentation allows each module type to maintain uniform size and shape characteristics, enabling easy color identification while recording multiple types of data simultaneously.
Solution Approach 2:
The patent introduces second modules at intermediate points between diagonally-adjacent first modules, effectively utilizing the spatial dimension between the primary module grid. This dimensional approach allows additional data to be recorded without interfering with the primary module structure, maintaining uniform appearance and color identification for both module types.
2Difficulty of detecting and measuring
If the two-dimensional symbol is enlarged to make colors of difficult-to-identify modules more identifiable, then color identification improves, but the overall size of the symbol increases
Solution Approach 1:
The patent applies local quality by ensuring that both first modules and second modules have uniform size and shape characteristics within their respective roles. The second modules are specifically designed to have comparable visual properties to first modules, allowing both to be easily identified at the same scale without requiring enlargement of the entire symbol.
3Quantity of substance
If second modules are placed in outer peripheral portions of first modules, then additional data can be recorded, but the number of second modules is limited and recording capacity is restricted
Solution Approach 1:
The patent utilizes the intermediate points between diagonally-adjacent first modules as placement locations for second modules. This approach effectively adds a second layer of module arrangement in the spaces between the primary grid, significantly increasing the number of available second modules and thus the capacity for additional data recording while maintaining full arrangement flexibility.

AI summary
The present invention facilitates, in a two-dimensional symbol in which a region where additional data is recorded is provided in addition to a region where normal data is recorded, identification of colors of the regions where the respective data are recorded. Vertically and horizontally arranged first modules are provided, and by the coloration patterns of the first module, a finder pattern for detecting a symbol position, a timing pattern for specifying the center position of the first module, and a first recording region where first data can be recorded are formed. In at least a partial region, a second module is disposed in a portion that does not overlap the first module and includes an intermediate point between the first modules adjacent to each other, and a second recording region where second data can be recorded is formed by the coloration pattern of the second module.
