RFID Manufacturing Status Sharing Without Centralized Databases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing processes rely heavily on production execution tracking software, which requires large databases and significant data flows, and there is a need to improve data sharing using RFID tags for enhanced traceability, compliance, and security without fully exploiting their potential.
Innovation Solution
A method and system that utilizes RFID tags attached to sub-products to manage manufacturing status data through aggregation, splitting, and merging operations, ensuring secure data sharing and reduced reliance on tracking software by embedding data directly into the tags, with encryption and blockchain technology for secure transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If production execution tracking software is used to manage manufacturing data, then data traceability and compliance are improved, but system complexity and data storage requirements increase significantly
Solution Approach 1:
The patent divides manufacturing data into discrete packets stored across multiple RFID tags attached to individual components and sub-assemblies. Each tag contains only the data relevant to its specific component, segmenting the overall data storage burden and eliminating the need for a centralized database system.
Solution Approach 2:
The RFID tags autonomously store and transmit their own manufacturing data without requiring external tracking software to manage or coordinate data collection. Each tag independently maintains its data integrity and can be queried by authorized systems, eliminating the need for complex software infrastructure.
2Ease of operation
If centralized database systems are used for manufacturing data management, then data accessibility is improved, but network dependency and vulnerability to outages increase
Solution Approach 1:
Data is segmented and distributed across multiple independent RFID tags rather than centralized in a single database. This distribution allows any authorized system to access relevant data directly from the tags without requiring network connectivity to a central server, eliminating network dependency.
Solution Approach 2:
Each RFID tag locally stores the manufacturing data specific to its component, making the data immediately accessible at the point of need without requiring remote access to a centralized system. This local storage capability ensures data availability even when network connections are unavailable.
3Loss of information
If all manufacturing data is stored in centralized systems, then data completeness is improved, but security risks and vulnerability to unauthorized modifications increase
Solution Approach 1:
Manufacturing data is segmented and distributed across multiple RFID tags attached to different components. This segmentation means that compromising one tag does not expose the entire manufacturing dataset, as each tag contains only a portion of the overall information.
Solution Approach 2:
While data is physically distributed across multiple tags, the system logically merges the information from all tags to reconstruct the complete manufacturing history. This merging occurs only when needed for verification or analysis, maintaining both security through distribution and completeness through logical integration.
4Reliability
If RFID tags are used for component identification, then tracking capability is improved, but the potential of these tags for data storage and sharing is not fully exploited
Solution Approach 1:
The RFID tags perform multiple functions: they serve as component identifiers for tracking purposes and simultaneously function as distributed data storage devices for manufacturing information. This multi-functionality fully exploits the potential of RFID technology beyond simple identification.
Solution Approach 2:
The RFID tags independently store and manage manufacturing data without requiring external systems to actively query or retrieve information from centralized databases. The tags autonomously maintain their data and can be directly accessed by authorized systems, enabling efficient data sharing.
