Reading Apparatus Embedding Wireless Tag Data in Image Files
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in effectively managing images printed on paper with wireless tags, such as RFID tags, as they require creating and linking tables to associate the printed images with data stored in the tags, which is inefficient.
Innovation Solution
A reading apparatus and method that includes a communication unit, scanner, and processor to communicate with and scan the wireless tag, acquire data, and generate a file embedding the data within the image, allowing for efficient management of the image and data association.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a table is created to link images and wireless tag data, then the association between printed images and tag data can be managed, but the system complexity and processing time increase
Solution Approach 1:
The patent merges the image data and wireless tag data into a single integrated file format. The reading apparatus reads both the printed image and the wireless tag data, then combines them into one file where the tag data is embedded within or associated with the image data structure, eliminating the need for separate table-based linking systems.
Solution Approach 2:
The patent introduces an intermediary file structure that serves as a container for both image and tag data. This intermediary format acts as a bridge between the physical printed document and the digital tag data, allowing efficient association without requiring complex external linking tables or additional data structures.
2Reliability
If a table is created to link images and wireless tag data, then the association between printed images and tag data can be managed, but the processing time increases
Solution Approach 1:
The patent performs preliminary actions by embedding the wireless tag data directly into the image file structure during the initial reading process. Instead of creating associations later through table lookups or external linking, the data association is established upfront when the file is created, significantly reducing subsequent processing time for data retrieval and association operations.
3Ease of operation
If data is embedded within the image file, then the association between image and data is simplified, but the file size increases
Solution Approach 1:
The patent applies the nesting principle by embedding the wireless tag data within the image file structure in a hierarchical manner. The tag data is nested inside the file container alongside the image data, creating a compact integrated structure. This nesting approach simplifies data association while managing file size efficiently through structured organization rather than simple concatenation.

AI summary
A reading apparatus includes a communication unit, a scanner, and a processor. The communication unit communicates with a wireless tag provided on paper. The scanner scans the paper. The processor acquires data from the wireless tag through the communication unit, acquires an image from the paper by using the scanner, and generates a file in which the data is embedded in the image as hidden characters.
