Solution Overview
Problem
Conventional RFID systems lack the functionality to effectively visualize, report, and manage large quantities of RFID data for efficient inventory and supply chain management, leading to inefficiencies in tracking and sourcing critical components across complex logistical supply chains.
Innovation Solution
A hub-and-spoke RFID inventory management system that utilizes cloud services platforms to interconnect hub and point-of-use facilities, enabling comprehensive data visibility, on-demand reporting, and inventory management services through a network of RFID readers and tags, with customizable dashboards and hierarchical access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional RFID readers are deployed to gather RFID tag information throughout the supply chain, then RFID data collection capability is improved, but the ability to visualize, report, and manage the collected data effectively deteriorates
Solution Approach 1:
The patent introduces an intermediary data management platform that sits between the RFID readers and the end users. This platform collects raw RFID data from multiple readers, processes it through centralized algorithms, and presents it in manageable formats through web-based interfaces. The intermediary handles data aggregation, filtering, and presentation, transforming the raw RFID tag information into actionable inventory management insights.
Solution Approach 2:
The system creates virtual copies of the physical inventory data through detailed digital representations. RFID tag information is copied and stored in centralized databases, creating digital twins of the physical supply chain components. These digital copies can be manipulated, analyzed, and visualized without affecting the physical goods, enabling effective data management and reporting.
2Stability of the object's composition
If a centralized system is used to manage all RFID data, then data consistency is improved, but system complexity and cost increase
Solution Approach 1:
The system is segmented into independent modular components: RFID readers at various locations, a centralized data collection server, processing algorithms, and web-based presentation layers. Each component performs a specific function and can be independently configured or replaced. This segmentation allows data consistency to be maintained through centralized coordination while keeping individual components relatively simple.
Solution Approach 2:
The centralized server performs multiple functions: collecting data from diverse RFID readers, processing and filtering information, storing data in standardized formats, and generating various types of reports. This multi-functionality consolidates what would otherwise require multiple separate systems, reducing overall complexity while maintaining data consistency across the entire supply chain network.
3Measurement precision
If multiple RFID readers are deployed at hub and spoke facilities, then inventory tracking coverage is improved, but data integration and centralized management difficulty increases
Solution Approach 1:
The patent merges data from multiple geographically distributed RFID readers into a single centralized database. Readers at hub facilities, spoke facilities, and intermediate locations all feed their collected RFID tag information to the central server, which consolidates it into a unified inventory view. This combining approach maintains comprehensive tracking coverage while simplifying management through centralized access and control.
Solution Approach 2:
The centralized server acts as an intermediary that standardizes and harmonizes data from different RFID reader locations. It implements common data formats, filtering criteria, and processing algorithms that work uniformly across all facilities. This intermediary layer abstracts the complexity of integrating multiple distributed readers, presenting a simplified interface for inventory management while maintaining comprehensive coverage.

AI summary
A hub-and-spoke radio frequency identification (“RFID”) inventory management system includes a distributed information-handling architecture together with consolidated access to system-wide information through cloud services. The system allows each supplier, hub, and point-of-use (“POU”) user interface to have consolidated access, visibility, analysis, and on-demand reporting of RFID data along with inventory management services implemented by one or more cloud services platforms. The cloud services can be provisioned on item-by-item, user-by-user, facility-by-facility bases in accordance with a hierarchical permission-based access system. The cloud services generally include, for example, a system of inventory management dashboards customizable to provide the specific inventory management information most pertinent for each user, supplier, hub, and POU. Item stocking MIN and MAX values for each item at each level are established and changed from time-to-time as deemed appropriate for each item stocked by each supplier, hub, and POU.
