Proximity-Based Playlist Merging via Cloud Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users in confined spaces, such as vehicles, are typically limited to listening to audio from a single device and playlist, unless using headphones, as media playback is confined to the paired device's available content.
Innovation Solution
A method for merging media playlists between mobile devices via a cloud-based media provider, where one device detects a nearby device playing media and sends a notification to the provider to share a portion of its playlist with the other device for merging, using proximity detection and cloud-based communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If media playback is confined to a single paired device, then audio output is simplified and device pairing is straightforward, but users in confined spaces are limited to listening to audio from only one device and playlist
Solution Approach 1:
The system segments the media playback function across multiple devices. Instead of confining playback to a single paired device, the patent allows the first device to detect the second device in proximity and share playlist information, enabling independent playback on both devices simultaneously. This segmentation resolves the contradiction by distributing playback capability while maintaining simple individual device operation.
Solution Approach 2:
The patent introduces an intermediary mechanism through proximity detection and cloud-based media provider coordination. The first device acts as an intermediary that detects the second device and facilitates playlist sharing without requiring complex direct pairing between devices. This intermediary approach enables multi-device playback while keeping the pairing process simple and automatic.
2Adaptability or versatility
If headphones are used to listen to audio from multiple devices, then users can access multiple playlists, but the solution requires additional hardware and reduces convenience
Solution Approach 1:
The patent makes the audio output system universal by enabling multiple devices to function as independent playback sources. Instead of requiring headphones as a special hardware addition, the system allows speakers, audio outputs, or other playback devices to be shared across multiple sources through proximity-based playlist sharing. This multi-functionality approach eliminates the need for additional hardware while maintaining playlist access versatility.
Solution Approach 2:
The system creates a copy of the playlist information from the first device to the second device through cloud-based coordination. Rather than physically sharing audio through headphones, the patent copies playlist data and enables independent playback on the second device. This copying mechanism provides multi-playlist access without requiring additional hardware connections.
3Adaptability or versatility
If playlist sharing between devices is enabled, then users can share and combine playlists in real-time, but requires detection of nearby devices and cloud-based communication infrastructure
Solution Approach 1:
The system performs preliminary actions by establishing cloud-based playlist storage and proximity detection capabilities before sharing is needed. The first device maintains its playlist in the cloud and has detection mechanisms ready, so when a second device enters proximity, the sharing can occur immediately without complex real-time negotiations. This preliminary setup reduces the apparent complexity during actual sharing operations.
Solution Approach 2:
The patent uses cloud-based media providers as intermediaries to facilitate playlist sharing. Instead of requiring direct complex communication between devices, the cloud service acts as a mediator that receives notifications from the first device, manages the playlist data, and enables the second device to access and merge playlists. This intermediary approach simplifies the infrastructure requirements by offloading complex coordination to the cloud service.

AI summary
Merging media in a playlist associated with a cloud based media provider of a first mobile device of a first user with media being played on a second mobile device of a second user within a specific proximity, such that the second mobile device receives at least a portion of a media playlist of the first user from the cloud based media provider for merging with the media currently being played by the second device.
