Information Terminal Personalized Menu Generation for Dietary Restrictions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food ordering systems fail to prevent vegetarian customers from receiving non-vegetarian food items, leading to discomfort and potential health risks, and they also compromise user privacy by transmitting sensitive information to restaurants without consent.
Innovation Solution
A method for controlling an information terminal that acquires a restaurant ID and seat ID through a common operation screen, retrieves menu information, generates a personalized menu based on user classification, and transmits food order information with the seat ID, ensuring accurate food delivery and maintaining user privacy by not sharing classification information with the restaurant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system transmits user classification information (vegetarian status) to the restaurant server, then the restaurant can provide appropriate food recommendations, but user privacy is compromised and sensitive information is leaked
Solution Approach 1:
The patent introduces a matching app as an intermediary layer between the user and the restaurant server. The matching app generates pseudonymous user profiles based on classification information locally, then transmits only these pseudonymous profiles to the restaurant server. This mediator approach enables the restaurant to provide personalized recommendations while preventing direct exposure of sensitive user information.
2Ease of operation
If the system manually processes vegetarian preferences at the restaurant, then service flexibility is maintained, but serving mistakes occur and customer comfort is compromised
Solution Approach 1:
The system performs preliminary processing of vegetarian preference information by generating pseudonymous user profiles before the ordering process begins. The matching app creates these profiles based on user classification information and stores them in advance. When users place orders, the restaurant server can automatically match orders with the pre-generated pseudonymous profiles, eliminating the need for manual verification during service and preventing serving mistakes.
3Ease of operation
If the system uses a standardized ordering interface, then ease of use is improved, but personalized menu generation based on vegetarian classification is not achieved
Solution Approach 1:
The patent segments the ordering system into two distinct interfaces: a common operation screen for basic ordering functions that all users share, and a personalized menu generation feature that activates specifically for users with vegetarian classification. The matching app detects vegetarian users and automatically generates customized menu recommendations, while non-vegetarian users continue using the standard interface without interruption.

AI summary
A method includes acquiring, on a basis of a restaurant ID, menu information indicating one or more foods provided by a restaurant over a network from a second server associated with the restaurant corresponding to the restaurant ID, transmitting identification information stored in an information terminal to a first server and acquiring classification information from the first server on a basis of the identification information, generating a personalized menu for the user corresponding to the classification information on a basis of the menu information and the classification information, and displaying the personalized menu through a second operation screen for accepting an order of a food to be provided by the restaurant, the second operation screen being displayed on a display of the information terminal carried by the user.
