Solution Overview

Problem

Users face inconvenience in obtaining digital contents as they need to physically visit stores for storage media and require a PC environment for internet-based purchases, which limits access and convenience.

Innovation Solution

A method for content sharing between a mobile terminal and a local server using metadata comparison and transmission, allowing users to request and receive desired content information and files via a wireless LAN, utilizing a client terminal and server terminal with metadata generation, matching, and communication modules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users purchase digital contents through traditional methods (physical stores or PC-based internet sites), then they can obtain digital contents, but they must visit stores personally or use a PC environment which reduces convenience and accessibility

Engineering Contradiction:

Improveconvenience of obtaining digital contentsVSAvoidaccessibility from mobile devices

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The server terminal is designed to provide contents sharing services to multiple types of terminals including mobile terminals and PC terminals through a unified system. The server can receive requests from mobile terminals, compare metadata, and provide contents information regardless of the terminal type, making the system universally accessible and eliminating the need for PC-specific environments

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The server terminal acts as an intermediary between mobile terminals and contents providers. It receives contents requests from mobile terminals, performs metadata comparison with stored contents information, and provides contents information or URIs back to the mobile terminal. This intermediary system enables mobile devices to access digital contents without requiring direct connection to content sources or PC environments

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If users download P2P software on PCs to obtain digital contents, then they can access digital contents via Internet, but they need a PC environment and must log on to Internet sites which increases operational complexity

Engineering Contradiction:

Improveaccess to digital contents via InternetVSAvoidoperational complexity of PC environment setup

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The server terminal automatically performs metadata comparison when it receives a contents request from a mobile terminal. The server compares the requested metadata with stored contents information, automatically identifies matching contents, and provides the contents information or URI back to the mobile terminal without requiring user intervention for complex operations

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical PC-based P2P software system with a wireless communication-based mobile terminal system. Instead of requiring PC hardware, P2P software installation, and internet site logins, the system uses wireless communication protocols between mobile terminals and server terminals to achieve the same functionality of accessing and sharing digital contents

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If mobile terminals store various contents locally, then users have content availability, but the memory capacity is limited and sharing with other users is difficult

Engineering Contradiction:

Improvememory capacity for storing contentsVSAvoidease of sharing contents with other users

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The system segments the contents storage function between mobile terminals and server terminals. Mobile terminals store only metadata and essential contents information locally, while the server terminal stores comprehensive contents information databases. This segmentation allows mobile devices with limited memory to access and share contents through the server's larger storage capacity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent adds a network dimension to local content storage by enabling wireless communication between mobile terminals and server terminals. Instead of relying solely on local memory capacity, the system uses the network dimension to access remote content repositories, effectively expanding the available storage and sharing capabilities beyond physical memory constraints

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

Provided is a contents sharing method between a mobile terminal and a local server. The contents sharing method between a client terminal storing metadata and a server terminal storing the metadata, the method comprising requesting the server terminal for a contents share service; and receiving information on contents corresponding to matching metadata as a result of comparing the metadata stored in the client terminal and the metadata stored in the server terminal, thereby sharing contents desired by the user without the user's intervention. Also, the user can communicate desired contents information with people in a bus, subway, library, etc., which forms a social network, and produces a contents flow between mobile terminals, thereby creating a new business model such as contents resale, promotion, etc.
