Solution Overview

Problem

Current audio/visual systems lack the ability to wirelessly transfer media files and media descriptive data between handheld devices and audio/visual systems, and do not allow for seamless wireless control of the audio/visual system from a handheld device, making it inconvenient to manage and play media content across devices.

Innovation Solution

The system enables wireless transfer of media files and media descriptive data between handheld electronic devices and audio/visual systems using Bluetooth technology, allowing for two-way communication to create a synchronized global view of media content and enabling wireless control of the audio/visual system from the handheld device, including features like automatic switching between devices and ambient noise management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless transfer of media files and descriptive data is implemented between handheld devices and audio/visual systems, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of media managementVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a media descriptive data transfer system that acts as an intermediary layer between handheld devices and audio/visual systems. This system automatically transfers metadata (artist, album, title, genre information) alongside media files, enabling seamless integration without requiring users to manually manage complex device connections or data synchronization protocols.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If two-way communication is established to create synchronized global view of media content, then adaptability is improved, but loss of information increases

Engineering Contradiction:
Improvemedia content synchronizationVSAvoiddata transmission errors
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system implements feedback mechanisms where media descriptive data is automatically exchanged between handheld devices and audio/visual systems. The transfer of metadata provides confirmation that communication channels are functional, allowing the system to verify successful data exchange and synchronize media libraries across devices without information loss.

Inventive Principle:
Principle #23Feedback

3Productivity

If automatic switching between devices is implemented, then productivity is improved, but device complexity increases

Engineering Contradiction:
Improvemedia playback efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent enables automatic device switching through self-service mechanisms where the system autonomously determines when and how to switch between handheld devices and audio/visual systems based on proximity detection and media playback state. This eliminates the need for manual user intervention in device switching while maintaining simple operation for the end user.

Inventive Principle:
Principle #25Self-service
