RFID Allergen Data Filtering for Retail Product Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems that provide allergen information through RFID tags in supermarkets display unnecessary allergen information for products not intended for purchase, making it difficult for customers to grasp relevant information.
Innovation Solution
An information processing apparatus with a wireless tag reader, storage device, and processor that reads tag information from products, filters allergen data based on customer designations, and outputs only the allergen information for designated products, allowing customers to focus on relevant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless tag reader reads tag information from all products on the display shelf, then the system can provide allergen information for all products, but the customer is presented with excessive allergen information including products they do not intend to purchase
Solution Approach 1:
The system segments the complete allergen information set by dividing it into two parts: all allergen information read from the product database, and the subset of allergen information for products containing the searched allergen. This segmentation allows the system to manage and present information in a controlled manner, showing only relevant information to the customer while maintaining access to complete information for verification purposes.
Solution Approach 2:
The system extracts and displays only the allergen information relevant to the customer's search criteria (products containing the searched allergen) while separating out the complete allergen information for all products. This extraction principle ensures that customers receive only the necessary information without being overwhelmed by data for products they are not interested in.
2Loss of information
If the system displays allergen information for all products, then no relevant information is missed, but customers cannot easily grasp the allergen information for products they intend to purchase
Solution Approach 1:
The display interface is segmented into distinct sections: one showing allergen information for the searched allergen across relevant products, and another showing complete allergen information for all products. This segmentation enables customers to easily access and understand the most relevant information first, while still providing access to complete information if needed.
Solution Approach 2:
The system applies local quality by providing different information presentations in different parts of the interface: summarized allergen information for products containing the searched allergen is prominently displayed, while complete allergen information for all products is available in a separate section. This allows each part of the interface to serve its specific purpose effectively.
3Quantity of substance
If the wireless tag reader reads information from multiple products, then the system has comprehensive data, but the customer is overwhelmed by unnecessary data for products not intended for purchase
Solution Approach 1:
The system extracts the essential allergen information for products containing the searched allergen from the complete dataset, presenting only this extracted information prominently to the customer. The complete allergen data for all products is maintained in the background but not displayed unless specifically requested, thereby reducing information presentation complexity while preserving data completeness.
Solution Approach 2:
The system performs partial action by displaying only the necessary subset of allergen information (for products containing the searched allergen) rather than all available information. This partial display approach reduces complexity for the customer while the system maintains the capability to access and display complete information when needed.

AI summary
According to an embodiment, an information processing apparatus acquires, on the basis of tag information read by a wireless tag read from a wireless tag attached to a product, allergen information indicating an allergen contained in the product. Further, the information processing apparatus accepts an input of designation information for designating a product whose allergen information is to be output. Further, the information processing apparatus outputs the acquired allergen information for a product designated on the basis of he accepted designation information.
