Smart Home Playlist Switching via Network Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In smart home play systems, switching playlists between play groups is inconvenient as it often requires disassembling and reassembling playing devices, disrupting the music experience when users move between rooms.
Innovation Solution
A control method and apparatus that allows seamless playlist switching between play groups by receiving identification changes on a user interface, transmitting acquisition instructions over a local area network, and controlling playing devices to synchronize playlists and progress, eliminating the need for device reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If playing devices are added or removed from play groups to switch playlists, then playlist switching between play groups is achieved, but device reassembly is required which disrupts music playback and reduces convenience
Solution Approach 1:
The patent separates the playlist data from the play group device composition. Each play group maintains its own playlist independently, allowing playlist switching without requiring device reassignment. The control apparatus manages multiple play group playlists separately, enabling users to switch between play group playlists through simple selection rather than device reconfiguration.
Solution Approach 2:
The patent implements playlist copying functionality where the control apparatus can copy playlists between different play groups. When switching playlists, the system copies the playlist data from one play group to another, maintaining the original device groupings while achieving playlist interchangeability without device reassembly.
2Adaptability or versatility
If playing devices are reconfigured to switch between different play groups, then playlist assignment is achieved, but continuous music playback is interrupted
Solution Approach 1:
The control apparatus pre-loads and maintains multiple play group playlists in ready state. When a playlist switch is requested, the system has the target playlist already prepared and available for immediate playback, eliminating interruptions. The system maintains multiple playlist instances simultaneously, so switching is instantaneous rather than requiring sequential reconfiguration.
3Stability of the object's composition
If device reassembly is required for playlist switching, then play group integrity is maintained, but user operation complexity increases
Solution Approach 1:
The control apparatus serves as an intermediary that manages playlist assignments independently of device groupings. It mediates between user playlist selection and play group execution, handling the complexity of playlist management while presenting a simple interface to users. The control apparatus abstracts the complexity of multiple playlist configurations away from the user, requiring only simple selection input.

AI summary
A control method for switching a playlist of a play system and apparatus are provided. The method includes receiving an identification change operation of a graphic label corresponding to a play status of a first play group on a user interface so that the identification change operation of the graphic label corresponding to the first play group is consistent with an identification change operation of a graphic label corresponding to a play status of a second play group; transmitting an acquisition instruction of a playlist to the first play group so that the first play group acquires a current playlist and a current play progress of the second play group via the local area network; and controlling at least one playing device of first play group for playing the play files of current playlist of second play group according to the current play progress of second play group.
