Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing music playback systems fail to personalize audio piece arrangements according to user preferences, leading to a lack of user satisfaction in music playlists and streams.

Innovation Solution

A method for determining the sequence of audio pieces based on user profiles, which includes rules related to metadata and acoustic parameters, allowing for personalized arrangement that matches individual user tastes by using a music playback device and server system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If music pieces are selected based on user likings, then user acceptance is improved, but the arrangement order of music pieces is not optimized for user pleasure

Engineering Contradiction:

Improveuser acceptanceVSAvoidplaylist arrangement

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system pre-determines optimal arrangement patterns for playlists before playback. User profiles and preference rules are established in advance, and arrangement patterns are calculated beforehand based on these profiles, so that when a playlist is created, the pieces are automatically arranged in the optimal sequence without requiring real-time computation or user intervention.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically arranges music pieces in playlists based on pre-established user profiles and preference rules without requiring manual user input. The arrangement process is autonomous, using the stored user information to self-determine the optimal sequence of music pieces for each playlist.

Inventive Principle:

Principle #25Self-service

2Device complexity

If the same playlist is played for different users, then system simplicity is maintained, but user-specific preferences are not satisfied

Engineering Contradiction:

Improvesystem simplicityVSAvoiduser-specific customization

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The system creates locally optimized playlists for each user by applying user-specific arrangement patterns to the same music content. Each user receives a personalized arrangement of music pieces based on their individual profile and preferences, while the underlying music library and system structure remain unchanged and simple.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system changes the arrangement parameter (sequence of music pieces) based on user profiles while keeping the music content itself unchanged. By varying only the order parameter according to user preferences, the system achieves personalization without complicating the overall system architecture or requiring different music libraries for different users.

Inventive Principle:

Principle #35Parameter changes

AI summary

Method for determining a sequence of audio pieces, comprising receiving a set of audio pieces, and determining the sequence of audio pieces by arranging audio pieces from the set in an order; wherein a position of a respective audio piece within the order is determined based on a user's personal profile, the user's personal profile includes rules descriptive of the user's preferences, the rules relating to attributes including meta data attributes and/or acoustic parameters of audio pieces, and wherein the position of the respective audio piece is determined depending on one of the attributes of the respective audio piece according to one of the rules.
