Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users face challenges in transferring playlists between personal media devices due to differences in operating systems, memory architectures, and hardware, making playlists from one device unusable on another.

Innovation Solution

A method is implemented to select and convert playlists on a first personal media device to a common format, allowing for transfer to a second personal media device, establishing communication and transferring the converted playlist.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If playlists are transferred directly between different personal media devices, then transfer speed is improved, but compatibility is worsened due to different operating systems, memory architectures, and hardware

Engineering Contradiction:

Improvetransfer speedVSAvoidcompatibility

Core Design Contradiction:

SpeedVSAdaptability or versatility

Solution Approach 1:

A common format playlist is introduced as an intermediary representation between source and target devices. The conversion module transforms device-specific playlists into this intermediate common format, which then serves as the basis for transfer to the target device. This mediator resolves the incompatibility between different device architectures while enabling efficient transfer.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the format parameters of playlists by converting them from device-specific representations to a common format. This parameter transformation involves mapping different operating system formats, memory architectures, and hardware specifications to a unified representation that can be universally interpreted across diverse personal media devices.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If playlists are converted to a common format before transfer, then compatibility is improved, but processing time is worsened due to the conversion step

Engineering Contradiction:

ImprovecompatibilityVSAvoidprocessing time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The conversion to common format is performed as a preliminary action before the actual transfer process. By completing the format transformation in advance, the system ensures compatibility is established upfront, allowing the subsequent transfer operation to proceed efficiently without repeated conversion overhead during the transfer itself.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If device-specific playlists are used, then device optimization is improved, but transferability is worsened across different personal media devices

Engineering Contradiction:

Improvedevice optimizationVSAvoidtransferability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The playlist data is segmented into two distinct components: the device-specific optimized representation and the universal common format representation. This segmentation allows each component to serve its specific purpose - the device-specific format maintains optimization for local playback, while the common format enables cross-device transferability.

Inventive Principle:

Principle #1Segmentation

AI summary

A method, computer program product and computing device for selecting at least one playlist for transfer, the at least one playlist being stored on a first personal media device. The at least one playlist is converted to a common format, thus generating a first common format playlist. Communication is established with a second personal media device. The first common format playlist is transferred to the second personal media device.
