Solution Overview

Problem

In client/server systems, users face inefficiencies when trying to use content data on multiple devices, as they need to upload and download content data between devices, which is time-consuming and labor-intensive.

Innovation Solution

A client device that includes a storage section for content data, a control section for acquiring and transmitting content identification information, and a transmission section to register and manage user-specific registration information with a server, allowing seamless access to content data across devices without the need for repeated uploads and downloads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the general client/server system is used to transfer content data between devices, then the content data can be accessed on multiple devices, but the user must perform manual upload and download operations which increases time consumption and operational complexity

Engineering Contradiction:

Improvecontent data accessibility across multiple devicesVSAvoiduser operation complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system enables automatic content data sharing between devices without requiring manual user intervention for upload and download operations. The server automatically identifies content data from the first device and transfers it to the second device based on device identification information and user authentication, making the system self-serving and eliminating the need for users to manually perform transfer operations.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary registration of device identification information and content data metadata with the server before actual content transfer is needed. When a user wants to access content on a different device, the system already has the necessary device identifiers and content information pre-registered, allowing for rapid automatic transfer without requiring manual search or upload operations.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If manual upload and download operations are performed for content data transfer, then content data can be shared between devices, but the time required for transfer increases significantly

Engineering Contradiction:

Improvecontent data sharing capabilityVSAvoidcontent data transfer time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system implements automatic feedback loops where the server continuously monitors device identification information and content data status. When content data needs to be transferred between devices, the server automatically detects the source and destination devices, validates user authentication, and initiates transfer without manual intervention, significantly reducing transfer time compared to manual operations.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical operations (user pressing buttons to upload and download) with automated electronic processes. The server automatically handles content data transfer using electronic identification and authentication mechanisms, substituting the manual mechanical process with an automated digital system that operates much faster.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If content data is manually uploaded to server and then downloaded to another device, then content accessibility is achieved, but the operational effort required increases

Engineering Contradiction:

Improvemulti-device content accessVSAvoidsystem operation complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The server device is designed with multi-functional capabilities that include device identification, user authentication, content data storage, and automatic transfer coordination. This universal system handles all operations related to multi-device content access through a single integrated platform, reducing the complexity that would otherwise require multiple separate manual operations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The server acts as an intermediary between client devices, automatically managing the content data transfer process. Instead of direct manual transfer between devices requiring user intervention, the server mediates the process by receiving content from the first device, validating it through authentication, and automatically delivering it to the second device, simplifying the overall system operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

There is provided a client device including a storage section which stores content data, a control section which acquires content identification information for identifying the content data stored in the storage section, and a transmission section which transmits, to a server device, a registration request including user identification information for identifying a user who uses the client device and the content identification information acquired by the control section, and which, when the server device holds the content data identified by the content identification information, causes the server device to hold information obtained by associating the user identification information with the content identification information as user-specific registration information.
