Mobile RFID Reader Tray for Inventory Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual inventory processes in material handling facilities, especially for high retail value items, are time-consuming and prone to human error due to the need for physical counting or barcoding.
Innovation Solution
An RFID reader tray mounted on a mobile cart that detects RFID tags on items using an RFID antenna and communicates with an inventory tracking system to verify item presence and count, reducing human intervention and error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inventory processes are used with physical counting or barcoding, then human operators can verify item presence, but the process is time-consuming and prone to human error
Solution Approach 1:
The patent replaces manual mechanical inventory processes (physical counting, barcoding) with an automated RFID-based detection system. The RFID reader tray with antenna automatically detects RFID tags on items, eliminating the need for human operators to manually count or scan barcodes, thereby reducing both time and human error while maintaining high accuracy
Solution Approach 2:
The patent introduces an RFID reader tray as an intermediary device between the inventory system and items. This tray contains an RFID antenna that acts as a mediator to automatically detect and communicate item information to the inventory management system, replacing direct human interaction and enabling fast, accurate inventory tracking
2Adaptability or versatility
If RFID reader tray is mounted on mobile cart, then inventory verification can be performed at multiple locations, but device complexity increases
Solution Approach 1:
The patent combines the RFID reader tray with a mobile cart, merging the inventory detection functionality with mobile transport capability. This integration allows the system to move to different storage locations while performing inventory verification, enhancing versatility without requiring separate mobile and fixed inventory systems
Solution Approach 2:
The mobile cart with integrated RFID reader tray serves multiple functions: it acts as both a transport vehicle and an inventory verification station. This multi-functional design allows a single device to perform both mobility and automated detection tasks, reducing the need for additional specialized equipment
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
Streamlines inventory processes by accurately identifying and counting RFID-tagged items, reducing time and error, and enabling real-time inventory management.
Implementation Method 1
The reader tray includes at least one RFID antenna disposed under the bottom support structure
Implementation Method 2
a shield disposed on the opposite side of the RFID antenna facing the bottom support structure for reflecting the RFID signals

AI summary
Embodiments herein describe an RFID reader tray which includes a receptacle for detecting RFID tags disposed on physical items. In one embodiment, a sidewall is disposed around the periphery of a bottom support structure and extends away from the bottom support structure to form the receptacle. The reader tray includes an RFID antenna disposed under the bottom support structure on which the items can be placed. The material of the bottom support structure is selected such that RFID signals emitted by the RFID antenna can radiate through the bottom support structure and reach RFID tags placed on items in the receptacle. In one embodiment, the reader tray includes a shield for reflecting the RFID signals so that the most of the RFID signals radiate through the bottom support structure and into the receptacle.
