Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printers require time and labor for users to connect and transmit image data from external devices, making the printing process cumbersome.
Innovation Solution
A printer with a built-in RFID tag reader and operation buttons that allows for non-contact reading of identification information from a display medium, enabling simple selection and printing of images without the need for external device connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional printer is connected to an external device in a wired or wireless manner to transmit image data, then printing functionality is achieved, but it requires time and labor for connection and data transmission operations
Solution Approach 1:
The printer performs self-service by automatically reading identification information from RFID tags on display media and autonomously retrieving and printing image data without requiring user connection operations to external devices. The printer's control unit automatically manages the entire process from RFID reading to image printing.
Solution Approach 2:
RFID tags on display media serve as intermediaries between the user and the printer's data system. Instead of directly connecting to external devices, users simply place display media with RFID tags on the printer, which automatically reads the identification information and retrieves corresponding image data for printing.
2Productivity
If a printer uses wired or wireless connection to external devices for printing, then image data can be transmitted, but the operation process becomes cumbersome and labor-intensive
Solution Approach 1:
The patent replaces mechanical connection operations (plugging cables, pairing devices) with electromagnetic field-based RFID communication. The printer's RFID reader automatically reads identification information from tags on display media through electromagnetic fields, eliminating the need for physical connections and complex pairing procedures.
3Ease of operation
If the printer automatically reads RFID tags and prints images without external device connection, then user labor is reduced, but the printer requires built-in RFID reading and image storage capabilities
Solution Approach 1:
Image data is preliminarily stored in the printer's storage unit before printing operations are needed. The control unit reads RFID tags on display media, retrieves corresponding pre-stored image data, and prints it automatically. This preliminary storage approach eliminates the need for real-time external device connections during printing.

AI summary
A printer (2) including a reading part (44), a determination part (94), and a print control part (96) is provided. The reading part (44) reads specific identification information in a noncontact manner from an RFID tag (88) that the specific identification information for identifying a sample image (76) is stored. By referring to a storage part (92) in which plural image data including an image data representing the sample image (76), and a correspondence information data table (98) indicating a correspondence relationship between the plural image data and the specific identification information for identifying the plural image data respectively is stored, the determination part (94) determines, from among the plural image data, the image data associated with the specific identification information read by the reading part (44). The print control part (96) controls printing on a nail (6) based on the determined image data.
