Portable RFID Terminal Visual Scan Trace Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RFID systems for retail inventory management suffer from incomplete coverage of merchandise on fixtures, leading to inaccurate inventory counts and sub-optimal revenue due to over- or under-stocking, as they lack effective localization of scanned items.
Innovation Solution
A portable RFID reading terminal that provides visual and audible feedback to indicate scanned and uns scanned areas, using a 2D imager and RF signal coverage shape to ensure comprehensive inventory tracking, integrated with existing handheld RFID readers to enhance operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If RFID reading terminal performs inventory scanning, then inventory count speed increases, but coverage completeness deteriorates leading to inaccurate counts
Solution Approach 1:
The patent implements visual feedback through a display showing scan trace overlay on an image of the physical structure. The system provides real-time feedback to the operator about which areas have been scanned and which remain, enabling corrective action to achieve complete coverage while maintaining efficient scanning speed
Solution Approach 2:
The system captures an image of the physical structure and generates a scan trace overlay before completing the inventory process. This preliminary visualization allows operators to plan and execute comprehensive scanning paths, ensuring all areas are covered while maintaining productivity
2Productivity
If RFID reading terminal scans quickly to improve productivity, then scanning speed increases, but scan coverage completeness deteriorates
Solution Approach 1:
The display shows real-time scan trace overlay on the physical structure image, providing immediate feedback to the operator about coverage status. This enables operators to maintain high scanning speed while ensuring complete area coverage by visually identifying and returning to missed regions
Solution Approach 2:
The system prepares the scan trace overlay and physical structure image before the scanning operation begins, allowing operators to understand the complete area to be scanned and plan efficient scanning paths that ensure comprehensive coverage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly improves the accuracy of inventory counts by ensuring over 90% of RFID tags are successfully acquired during the inventory process, reducing the need for rescan and enhancing revenue through precise inventory management.
Implementation Method 1
An RFID reading terminal can be configured to read the memory of an RFID tag attached to an inventory item
Implementation Method 2
capture an image of at least one part of a physical structure sustaining a plurality of inventory items

AI summary
A method of reading RFID tags may include providing a device that can read barcodes and RFID tags. The barcodes may be attached to an object and respectively having a predetermined sequential read order. While reading the barcodes in the predetermined sequential read order, outputting an interrogation signal to RFID tags so that the RFID tags can be read while the barcode reader moves to sequentially read the barcodes in the predetermined sequential order.
