Combined RFID Barcode Reader with Rotating Antenna Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems require separate RFID and image code readers, leading to inefficiencies in product identification due to the need for selective use based on different identification methods, and existing solutions do not provide a reader capable of reading both RFID tags and image codes.
Innovation Solution
A combined reading apparatus with a plate panel for RFID tag recognition, an image code reader, a connection bar, a grip, and a control unit, which includes a wrist support to distribute the weight and rotate the plate panel for improved recognition rates, and extends the antenna for increased recognition range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate RFID reader and image code reader are used, then product identification can be performed using different identification methods, but device complexity increases and operational efficiency decreases
Solution Approach 1:
The patent combines the RFID reader and image code reader into a single integrated device. The housing contains both an RFID antenna for wireless communication and an image code reader with camera for optical scanning, allowing both identification methods to be performed by one device rather than requiring separate readers.
Solution Approach 2:
The integrated reading apparatus is designed to perform multiple functions: it can read RFID tags using the antenna and can scan image codes (barcodes, QR codes) using the camera. The control unit manages both reading mechanisms, making the device universal for different product identification methods.
2Weight of moving object
If RFID reader size is maintained, then portability is preserved, but integration of image code reader may increase weight
Solution Approach 1:
The image code reader components (camera, processing unit) are nested within the existing RFID reader housing structure. The antenna is integrated into the plate panel, and the camera is positioned to share the same operational space, allowing dual functionality without proportionally increasing overall device size or weight.
3Measurement precision
If plate panel is rotated based on RFID tag signal, then recognition rate increases, but device complexity increases
Solution Approach 1:
The plate panel is made rotatable around a vertical axis based on the direction of the RFID tag signal received by the antenna. The control unit processes the signal direction and automatically rotates the plate panel to optimize the antenna's orientation toward the tag, dynamically adapting to the tag's position to improve recognition rates.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simultaneous recognition of RFID tags and image codes while maintaining the size and weight of an RFID reader, distributing the load on the wrist, and optimizing RFID tag recognition rates by rotating and extending the antenna.
Implementation Method 1
an antenna adapted to transmit and receive an RF signal to and from an RFID tag is included therein
