Item Information Reading Apparatus Automatic Tag Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing item information reading apparatuses require operators to consciously select between reading barcodes and wireless tags, leading to inefficiencies and potential errors when both types of tags are present on an item.
Innovation Solution
An item information reading apparatus equipped with an antenna for wireless tag reading and a scanner for barcode reading, along with a processor that compares and transmits the read information, allowing automatic detection and processing of both types of tags without operator intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator manually selects between reading barcode or wireless tag, then the reading process can be controlled, but the operation efficiency decreases and potential errors increase when both tags are present
Solution Approach 1:
The reading apparatus automatically performs both barcode and wireless tag reading operations without requiring operator selection. The system self-determines which tags are present and executes the appropriate reading sequence, eliminating the manual selection step while maintaining full reading capability.
Solution Approach 2:
The apparatus performs preliminary detection to identify whether a barcode or wireless tag is present on the item before executing the reading operation. This advance identification allows the system to prepare and execute the optimal reading sequence automatically, improving efficiency without losing operator control options.
2Productivity
If the apparatus automatically reads both barcode and wireless tag, then reading efficiency improves, but the device complexity increases
Solution Approach 1:
The reading apparatus integrates both barcode reading and wireless tag reading capabilities within a single device. By combining multiple reading functions into one universal apparatus, the system achieves improved reading efficiency without proportionally increasing device complexity, as shared components and integrated control reduce overall system burden.
Solution Approach 2:
The apparatus merges the barcode reading function and wireless tag reading function into a unified reading system. The control unit coordinates both reading operations, and the information output unit handles data from both sources, consolidating what could be separate devices into one integrated system that improves efficiency while managing complexity through unified architecture.
3Measurement precision
If the apparatus compares code information from both reading methods, then data accuracy improves, but the processing time increases
Solution Approach 1:
The control unit implements a feedback mechanism where code information from barcode reading and wireless tag reading is compared and verified against each other. This cross-validation process improves data accuracy by identifying and correcting potential reading errors, while the automated feedback loop manages processing time through efficient comparison algorithms.

AI summary
An item information reading apparatus includes an antenna; a scanner; a network interface connectable to an external device; and a processor configured to cause the antenna to wirelessly read code information for uniquely identifying an item from a wireless tag, cause the scanner to read code information for uniquely identifying an item from a code symbol, compare the code information read by the antenna with the code information read by the scanner, and cause the network interface to transmit to the external device one or both of the code information read by the antenna and the code information read by the scanner based on a comparison result of the code information read by the antenna with the code information read by the scanner.
