Barcode Identification Control Using Sequential Type Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In healthcare settings like hospitals and pharmacies, identifying objects using barcodes requires manual specification of barcode types, making the process complex and time-consuming when dealing with multiple objects of different types.
Innovation Solution
An apparatus and process that store article numbers assigned to various types (PCN, EAN, IAN, SAN) in memory, allowing detected barcode information to be compared automatically with these types in a specified sequence, reducing the need for repeated user input and simplifying identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual specification of barcode type is required for each object identification, then identification accuracy can be ensured, but identification efficiency and user convenience deteriorate
Solution Approach 1:
The system pre-stores multiple article number types (PCN, EAN, IAN, SAN) and their corresponding article numbers in memory before identification begins. When a barcode is scanned, the control automatically compares the detected information against all stored types in sequence without requiring manual specification, thus maintaining accuracy while improving efficiency
Solution Approach 2:
The control unit performs automatic comparison and identification without user intervention. The system serves itself by autonomously determining the correct article number type through sequential comparison with stored data, eliminating the need for manual specification while ensuring accurate identification
2Reliability
If manual specification of barcode type is required for each object identification, then correct article matching can be ensured, but operation complexity increases
Solution Approach 1:
The control unit autonomously performs the complete identification process by automatically comparing detected barcode information with stored article numbers across multiple types. The system determines the correct match without user input, ensuring reliability while simplifying operation to merely scanning the barcode
Solution Approach 2:
All possible article number types and their corresponding numbers are pre-loaded into memory before operation. This preliminary preparation enables the control to automatically perform correct matching without requiring the user to manually specify types during operation
3Measurement precision
If repeated manual specification is required for different barcode types, then precise article identification can be achieved, but time consumption increases
Solution Approach 1:
The control continuously and automatically compares detected barcode information against all stored article number types in sequence without interruption or user intervention. This continuous automatic process maintains precise identification while eliminating the time loss associated with repeated manual specifications
Solution Approach 2:
All article number types and their corresponding numbers are pre-stored in memory before the identification process begins. This preliminary preparation enables continuous automatic comparison across multiple types without requiring repeated manual input, thus maintaining precision while reducing time consumption

AI summary
The invention relates to an apparatus (10) and a corresponding process for identifying an object (20) with an article dependently upon a piece of barcode information detected from a barcode (30) with which the object (20) is identified. Here a number of article numbers are stored in a memory (60) which are assigned, on the one hand, to a number of articles and on the other hand to a number of different article number types. According to the invention, the piece of barcode information detected is compared with article numbers stored in the memory (60) dependently upon a specified sequence of article number types. In the case of the piece of barcode information detected corresponding with one of the stored article numbers, the object (20) is identified with the article assigned to this article number.
