Information Terminal Order Screen for Dietary Restriction Filtering

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing food ordering systems fail to prevent serving mistakes where food ordered by one customer is mistakenly served to another customer of a different religion, and they also risk leaking sensitive user information to the restaurant.

Innovation Solution

A method for controlling an information terminal that acquires a restaurant ID and seat ID through a common operation screen, extracts compatible foods based on user religion information, and displays them on a customized order screen, ensuring that food order information is transmitted with the seat ID rather than user identification, thereby preventing incorrect serving and information leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system transmits user identification information to the restaurant server, then the restaurant can identify and serve the correct customer, but user privacy information may be leaked

Engineering Contradiction:

Improvecustomer identification accuracyVSAvoiduser privacy leakage

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent extracts and transmits only the necessary seat ID information to the restaurant server, while keeping the user's religion information and other sensitive personal data local on the information terminal. This selective extraction allows the restaurant to identify the correct seat and customer without receiving unnecessary private information, thus resolving the contradiction between reliable identification and privacy protection.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The seat ID acts as an intermediary identifier that connects the user to their seat without exposing sensitive personal information. The system uses this intermediary identifier to transmit order information to the restaurant server, enabling accurate serving while maintaining user privacy, as the server can associate the seat ID with the user's religious dietary restrictions through the customized menu interface.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the system displays the full menu to all users, then the restaurant can offer complete menu options, but users with religious dietary restrictions may be exposed to incompatible food items

Engineering Contradiction:

Improvemenu completenessVSAvoiddietary restriction violations

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by customizing the menu display based on each user's religious dietary restrictions. The system retrieves the user's religion information from local storage and filters the menu items accordingly, so that each user sees a personalized menu that excludes incompatible food items. This allows the restaurant to maintain complete menu data while presenting only appropriate options to each user, preventing dietary restriction violations.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system performs preliminary filtering of menu items based on the user's religious dietary restrictions before displaying the menu. By pre-processing the menu data according to the user's religion information stored locally, the system ensures that only compatible food items are presented to the user, eliminating the need for users to navigate through incompatible options and preventing potential dietary violations.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the system uses customized operation screens for each restaurant, then user experience is improved, but system complexity increases

Engineering Contradiction:

Improveuser experienceVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a universal menu interface design that can adapt to multiple restaurants and dietary requirements through a single standardized system. The customized operation screens are generated dynamically based on the restaurant ID and user's religious restrictions, rather than requiring separate custom interfaces for each restaurant. This multi-functional approach allows the system to provide personalized user experiences while maintaining manageable system complexity through a unified architecture.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method acquires, 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, acquires, from a first server, religion information, extracts one or more first foods compatible with the religion information on a basis of the menu information and the religion information, displays the one or more first foods through a second operation screen for accepting an order of a food to be provided by the restaurant of a user, and transmits food order information indicating a food selected from among the one or more first foods to the second server.
