Solution Overview

Problem

Information providing devices in public places face security issues due to the need for user input of identification information, which can be compromised by unspecific users.

Innovation Solution

A system where a server communicates with a terminal device to receive device and user identification information, allowing the server to transmit personalized information to the information providing device without requiring user input, using methods like outputting device IDs via sound waves or short-range radio for secure association.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user input of identification information is required for personalized information provision, then information can be personalized for the user, but security is compromised because unspecific users can access the device in public places

Engineering Contradiction:

ImprovesecurityVSAvoiduser input requirement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The terminal device automatically transmits user identification information to the information providing device without requiring manual user input. The device uses acquired device identification information to initiate automatic authentication, allowing the system to serve itself by eliminating the need for users to manually enter credentials.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent introduces device identification information as an intermediary element that enables automatic authentication. This intermediary allows the terminal device to be identified and authenticated by the information providing device without direct user intervention, bridging the gap between automatic operation and secure access.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If device identification information is transmitted automatically, then ease of operation is improved by eliminating user input, but security may be worsened if the transmission method is not secure

Engineering Contradiction:

Improveautomatic transmissionVSAvoidtransmission security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces manual mechanical input (user typing identification information) with automatic electronic transmission of device identification information. This substitution enables ease of operation by eliminating physical user interaction while maintaining security through automated authentication protocols.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An object is to provide an information providing system and an information providing method in which an information providing device can provide information personalized for a user without an input of identification information of the user into the information providing device.A server device receives, from a terminal device that has acquired device identification information identifying the information providing device, the device identification information and user identification information identifying a user. The server device transmits information for the user identified by the user identification information to the information providing device identified by the device identification information. The information providing device receives the information for the user. The information providing device provides information based on the information for the user.
