Printed Matter Content Delivery via Embedded Recognition Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing QR code technologies are underutilized for content delivery, primarily limited to accessing designated web pages without offering advanced features like offline content retrieval and server capacity reduction.
Innovation Solution
A content delivery service method using printed matter, where a service subscriber A edits content, generates a recognition code, and prints it onto an image, allowing subscriber B to decode and access the content offline without storing the image on the server, thereby reducing server capacity load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If QR code is used to store and transmit content information, then content delivery capability is improved, but server storage capacity requirement increases
Solution Approach 1:
The patent extracts the image data from the server storage and replaces it with a QR code containing only the URL link. The server stores only the lightweight URL information rather than the complete image data, significantly reducing server storage requirements while maintaining content delivery capability through the QR code linkage.
Solution Approach 2:
The patent uses a QR code as a copy or reference that points to the actual content stored on the server. Instead of storing the full image content on the server, the system stores a compressed reference (QR code with URL) that can be scanned to access the original content, reducing the storage burden on the server.
2Reliability
If content is stored on server for offline access, then content availability is improved, but server capacity load increases
Solution Approach 1:
The patent extracts essential content information (URL link) from the full image data and stores only this lightweight reference on the server. The complete image data is stored locally on the user's device, ensuring content availability offline while minimizing server capacity load through selective storage of only necessary linkage information.
3Quantity of substance
If QR code is used for content encoding, then information storage density is improved, but content visibility in printed matter decreases
Solution Approach 1:
The patent introduces the QR code as an intermediary element that bridges the printed matter and the actual content. The QR code is embedded in the printed image as a visual marker, and when scanned, it acts as a mediator to retrieve and display the full content, maintaining both high information density in the compact QR code and effective content accessibility through the scanning action.
Data Source
AI summary
Provided is a content delivery service method using printed matter. The content delivery service method using printed matter may include executing, by a first terminal, a service app and selecting an image, editing content on the selected image in an app screen, sending, by the first terminal, the image and information about the edited content to a server, storing, by the server, the image and the information about the edited content and sending information about the storage to the first terminal, generating, by the first terminal, specific recognition code in which the storage information has been recorded and inserting the specific recognition code into the image, and sending, by the first terminal, the image into which the recognition code has been inserted to a printing device so that the image is printed by the printing device.
