Two-dimensional code design region segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-dimensional codes face limitations in incorporating arbitrary designs, as design patterns are restricted to specific areas and formats, affecting data storage capacity and recognition accuracy.
Innovation Solution
A two-dimensional code design that includes a separate region for design-embedding information, allowing arbitrary images or designs to be added without interfering with data analysis, using a system with formation information blocks and design-embedding information blocks to determine and position the design region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If design patterns are incorporated into conventional two-dimensional codes, then design properties are improved, but data storage capacity is reduced
Solution Approach 1:
The two-dimensional code is divided into distinct functional regions: a data region for storing coded message data and a design-embedding region for incorporating arbitrary designs. This segmentation allows both data storage and design incorporation to coexist without interfering with each other, resolving the contradiction between maintaining data storage capacity and improving design properties.
Solution Approach 2:
The design-embedding region is extracted as a separate functional area from the data region. By taking out the design elements from the data-carrying cells and placing them in a dedicated region, the patent enables design incorporation without reducing the data storage capacity of the remaining code structure.
2Adaptability or versatility
If design patterns are superimposed on code symbols, then design properties are improved, but error correction capability is weakened
Solution Approach 1:
The patent segments the code into a data region that maintains error correction capability and a separate design-embedding region. By placing designs in their own dedicated region rather than superimposing them on code symbols, the error correction capability of the data region is preserved while still allowing arbitrary designs to be incorporated.
3Ease of manufacture
If design regions are restricted to specific positions, then manufacturing simplicity is improved, but adaptability is reduced
Solution Approach 1:
The patent designates a specific local region (the design-embedding region) with the quality of accommodating arbitrary designs. This localized approach maintains manufacturing simplicity by defining a clear boundary for design placement, while simultaneously improving adaptability by allowing any design to be placed in that region without restricting the overall code structure.
4Adaptability or versatility
If arbitrary images are added to data storage regions, then design properties are improved, but recognition accuracy is reduced
Solution Approach 1:
The patent clearly segments the code into a data region for machine recognition and a design-embedding region for visual design. By separating these functions into distinct regions, arbitrary images can be added to the design region without interfering with the recognition accuracy of the data region, as the analysis device can distinguish between the two areas.

AI summary
Disclosed is a two-dimensional code having improved design characteristics, for which any image can be added. The disclosed two-dimensional code divides data displayed in binary code into cells, arranges same as a pattern in a two-dimensional matrix, and has a position detection pattern. The two-dimensional code has embedded design information that indicates the existence of design areas wherein any design can be arranged and, if a design area exists, the position of the design area.
