Electronic Label Integrating RFID Reading for Price Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic label systems for displaying prices and managing data in sales areas are inefficient due to the need for separate RFID reader devices, which are costly and inconvenient for employees, and do not allow information from RFID chips to be displayed on the label screen.
Innovation Solution
An electronic label with integrated RFID reading means, a processing unit, and memory that can read and store information from RFID chips, allowing this information to be displayed on the label screen, with control over reading distance and activation, and the ability to transmit and receive data from a central server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If RFID reading means are integrated into the electronic label, then information access efficiency is improved and employee burden is reduced, but device complexity increases
Solution Approach 1:
The patent integrates RFID reading means directly into the electronic label structure, combining previously separate functions (RFID reading and electronic display) into a single integrated device. This allows employees to scan and display product information simultaneously without requiring separate reader devices, thereby improving information access efficiency while managing device complexity through functional integration.
2Ease of manufacture
If RFID reading means are integrated into the electronic label, then equipment cost is reduced, but device complexity increases
Solution Approach 1:
The electronic label is designed to perform multiple functions: displaying traditional price information from the central server and reading/displaying RFID chip information. This multi-functional design eliminates the need for separate RFID reader equipment, reducing overall system cost while consolidating functionality into a single device that handles both display and reading operations.
3Loss of information
If RFID information is displayed on the label screen, then information completeness is improved, but information management complexity increases
Solution Approach 1:
The processing unit automatically detects when an RFID chip is in proximity, reads the information, and displays it on the screen without requiring manual intervention. The system self-manages the information flow from RFID reading to display presentation, reducing the complexity of information management while ensuring complete product information is available on the label screen.

AI summary
The invention relates to an electronic label (10) of a system for displaying, in particular prices at a sales area comprising a display screen (1), a memory (2) for storing displayable data items, interfacing means (4) provided with a central server (3) of the display system and a processing unit for controlling the storage of data items transmitted from the central server to the memory (2) through the interfacing means (4) and for controlling the display of the data items stored in the memory (2) on the display screen (1). Said label is characterised in that it also comprises reading means (6) for reading the information items contained in an identification chip (7) by means of RFID radio frequency, the processing unit (5) is also used for controlling the reading of the information items contained in the RFID chip (7) by said reading means and for storing said read information items in the memory (2) in such a way that the information items of the chip RFID (7) are displayable on the display screen (1) of the electronic label (10) by the instruction of the processing unit (5).
