Solution Overview

Problem

Current systems do not allow users to transfer and synchronize digital content, such as music and videos, from a personal computer to a mobile handset over a wireless network, limiting user access to their own content on mobile devices.

Innovation Solution

A method and system that enables users to download digital content from a personal computer to a mobile handset via a wireless network, synchronizing the content, file structure, and metadata, using a server that connects the devices over the internet, allowing for seamless transfer and organization of digital content across devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users transfer digital content from PC to mobile handset through direct hardwired connection (USB cable), then transfer reliability is improved, but ease of operation deteriorates due to physical connection requirements

Engineering Contradiction:

Improvetransfer reliabilityVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical USB cable connection system with a wireless communication system. The personal computer and mobile handset establish a wireless connection (e.g., Wi-Fi, Bluetooth) to transfer digital content, eliminating the need for physical cable connections while maintaining transfer reliability through structured wireless communication protocols.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If users access digital content through wireless network via server, then ease of operation is improved, but content catalog size is limited to provider offerings

Engineering Contradiction:

Improveease of operationVSAvoidcontent catalog size

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent introduces a server as an intermediary component that enables the personal computer to share its digital content library with mobile handsets over a wireless network. The server acts as a mediator that allows users to access their own extensive content catalogs (music, videos, etc.) stored on their PC through the wireless network, rather than being limited to pre-provided content.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables the personal computer to serve multiple functions: it acts as both a content storage device and a content distribution server. The wireless communication capability allows the same PC to be accessed by multiple mobile handsets, providing universal access to the user's digital library across different devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If users download content over wireless network, then ease of operation is improved, but transfer speed is reduced compared to direct connection

Engineering Contradiction:

Improveease of operationVSAvoidtransfer speed

Core Design Contradiction:

Ease of operationVSSpeed

Solution Approach 1:

The patent implements dynamic adaptation of content transfer parameters based on wireless network conditions. The system adjusts transfer speed, buffering, and content prioritization according to the available wireless bandwidth and network state, optimizing the balance between ease of wireless operation and actual transfer speed.

Inventive Principle:

Principle #15Dynamics
