Audio Signal-Based Information Management System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal devices require large storage capacity to store various information for users, such as in exhibition facilities or transport systems, leading to inefficiencies in storage and data management.
Innovation Solution
An information management system that acquires audio signals and related information, associates identification information with the audio signals, and transmits the related information to the terminal device, reducing the need for large storage capacities by using audio signals to convey identification information and providing related information on demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If information is stored in advance in a portable terminal device, then information can be provided to users, but the required storage capacity increases
Solution Approach 1:
The patent extracts the information storage function from the terminal device and relocates it to a server. The terminal device only stores minimal identification information, while comprehensive information is stored externally on the server and retrieved on-demand via network connection, thereby dramatically reducing terminal storage requirements while maintaining full information provision capability
Solution Approach 2:
The patent introduces a server as an intermediary between the terminal device and the information repository. The server acts as a mediator that stores comprehensive information, receives requests from terminal devices, and provides requested information, enabling the terminal to access extensive information without storing it locally
2Adaptability or versatility
If various information is provided to users, then user service quality improves, but terminal device complexity increases
Solution Approach 1:
The patent extracts complex information management functions from the terminal device and places them on the server. The terminal only handles simple identification and request operations, while the server manages information storage, retrieval, and delivery, thereby providing diverse information without increasing terminal complexity
Solution Approach 2:
The server is designed as a universal information provision platform that can handle multiple types of information requests through a standardized interface. This multi-functional server architecture allows diverse information services to be provided without requiring different terminal configurations for different information types

AI summary
An information management system includes: an audio signal acquisitor configured to acquire an audio signal representing a guide voice; a related information acquisitor configured to acquire related information that is related to the guide voice; an association manager configured to associate the related information acquired by the related information acquisitor for the guide voice with identification information that is notified to a terminal device upon emission of the guide voice corresponding to the audio signal; and an information provider configured to receive from the terminal device an information request including the identification information notified to the terminal device and to transmit to the terminal device the related information associated by the association manager with the identification information.
