Billboard with Distributed Color Blocks for Scannable Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional billboards with small two-dimensional codes are inconvenient for users to scan, especially from a distance, and cannot serve as effective index means due to low definition when captured in images.
Innovation Solution
A billboard with a front face divided into color blocks that function as color geometric graphic code elements, allowing optical identification and decoding at a normal viewing distance, enabling users to capture and retrieve encoded information associated with the advertisement content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the size of the two-dimensional code is enlarged to be recognizable at normal viewing distance, then the code can be scanned from a distance, but the valuable advertisement area is compromised
Solution Approach 1:
The billboard front face is segmented into multiple color blocks that collectively form the encoded information. Each color block represents a portion of the overall code, and together they create a distributed encoding system that covers the entire billboard surface rather than concentrating the code in one location.
Solution Approach 2:
The color blocks serve dual functions: they display advertisement content while simultaneously encoding information. The entire billboard surface becomes both the advertisement medium and the encoding medium, eliminating the need for separate code areas and maximizing space utilization.
2Reliability
If a traditional two-dimensional code is placed on a billboard, then it provides a scanning function, but it cannot serve as an effective index means when captured in images due to low definition
Solution Approach 1:
The encoding system transitions from a small, concentrated two-dimensional code to a distributed pattern across the entire billboard surface. By spreading the encoded information across multiple color blocks throughout the advertisement area, the system ensures that captured images contain sufficient code information regardless of capture distance or angle.

AI summary
A billboard containing encoded information comprising: a billboard body comprising a front face presenting an advertisement content; and a plurality of color blocks being distributed in a preset mode on the front face and each of which individually covering a part of the front face, wherein the plurality of color blocks are encoded as color geometric graphic code elements and the entire front face can be optically identified and decoded to obtain the encoded information when captured by a mobile terminal, and the encoded information or the information decoded by the mobile terminal and imported to a web page is associated with the advertisement content. The billboard containing the encoded information allows a user, at a normal viewing distance, to scan, identify and decode the billboard to obtain the encoded information and to perform an image indexing, thereby further improving the publicity effect of the advertisement.
