Automated Label Dispensing via RFID Database Query
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information handling system assembly lines, the rapid pace of production often leads to errors and inefficiencies in manually selecting and affixing labels on systems-under-assembly, resulting in incorrect or missing labels due to the short time available for label selection.
Innovation Solution
An automated system utilizing RFID technology to write and read service tags, search databases for matching parts listings, and control label dispensers to accurately and efficiently attach labels to the systems-under-assembly, ensuring correct association of labels with internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual label selection is used in high-speed assembly, then assembly speed is maintained, but label accuracy deteriorates due to time constraints
Solution Approach 1:
The patent replaces manual mechanical label selection with an automated system that uses RFID readers to identify systems-under-assembly, database queries to determine required labels, and automated label dispensing mechanisms. This substitution eliminates human reaction time constraints while maintaining high assembly speed and improving label accuracy.
Solution Approach 2:
The system performs self-service by automatically identifying systems-under-assembly through RFID tags, querying its own database for required labels, and dispensing labels without human intervention. This autonomous operation eliminates manual selection errors while maintaining production speed.
2Manufacturing precision
If automated label dispensing is implemented, then label accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal labeling system where a single RFID reader, database, and dispensing mechanism handle multiple labeling tasks for different system types. This multi-functional approach improves label accuracy across diverse products while limiting complexity growth through consolidation rather than requiring separate systems for each product type.
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 system significantly improves label accuracy and efficiency, reducing errors and enhancing the assembly line process by allowing for precise and rapid label dispensing, even in high-speed environments.
Implementation Method 1
The RFID writer is located at a first stage of an assembly line and is configured to write a service tag (ST) identifier to an RFID tag associated with a bin on the assembly line
Implementation Method 2
The RFID reader is located at a second stage of the assembly line and is configured to read the ST identifier from the RFID tag

AI summary
A system and method are disclosed for automatically dispensing labels for information handling systems being assembled, in an assembly line that is configured to produce many different types of information handling systems with differing internal components. In some embodiments, a service tag identifier and parts listing are associated with each information handling system-under-assembly. The service tag identifier is written to an RFID tag that can be read at various stages of assembly. In some embodiments, when an assembly bin arrives at a label station of the assembly line, the RFID tag is read and a database is searched for the matching service tag and the associated parts listing. One or more appropriate labels are then automatically dispensed in response to the components in the listing. In this manner, correct association of labels with the components is maintained, and the search and dispensing process is performed in an efficient manner.
