Solution Overview

Problem

Existing music playback systems fail to dynamically adapt music playlists to users' real-time situations and preferences, such as location, activity, time, and environmental conditions, leading to an inadequate music experience.

Innovation Solution

An electronic device with a music play system that includes modules for determining situation and preference parameters, generating a tailored music playlist, and adjusting it based on detected dynamic parameters, using a server to provide relevant audio files and adjusting playback settings like volume and playlist order.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a static music playlist is used for playback, then the device complexity is reduced, but the adaptability to user situations and preferences deteriorates

Engineering Contradiction:

Improveadaptability to user situations and preferencesVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The music playback system transitions from a static playlist to a dynamic playlist that automatically adjusts based on real-time detection of user situation parameters (location, time, activity) and preference parameters (music genre, tempo, volume). The system continuously monitors these parameters and regenerates the playlist to match current user needs, making the playback experience adaptive rather than fixed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements feedback loops where detected situation and preference parameters are continuously fed back to the music playback module. The detection modules monitor user context and music playback effects are fed back to adjust future playback decisions, creating a closed-loop system that learns and adapts to user preferences over time.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If dynamic parameter detection and playlist adjustment is implemented, then the personalized music experience is improved, but the loss of time for processing and generating playlists increases

Engineering Contradiction:

Improvepersonalized music experienceVSAvoidtime for processing and generating playlists

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-detecting user situation parameters and pre-generating playlist options based on predicted user preferences. Instead of waiting for explicit user input, the system proactively prepares multiple playlist candidates and pre-loads audio files, reducing the time required when actual playback decisions need to be made.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes parameters by using simplified detection thresholds and pre-defined preference categories to reduce processing complexity. Instead of analyzing every possible parameter in detail, the system uses key parameters (location, time, activity level) with simplified detection methods, and maps them to pre-established music preferences, significantly reducing processing time while maintaining personalization quality.

Inventive Principle:

Principle #35Parameter changes

3Measurement precision

If multiple detection modules are used to detect situation and preference parameters, then the measurement precision of user context is improved, but the device complexity increases

Engineering Contradiction:

Improvemeasurement precision of user contextVSAvoiddevice complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system applies multi-functionality by using a single integrated detection module that performs multiple detection functions simultaneously. Rather than having separate dedicated modules for each parameter (location detection, time detection, activity detection), the system uses one multi-functional detection module that can measure various situation and preference parameters, reducing the number of components while maintaining comprehensive detection capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If the system dynamically adjusts playlist and playback settings, then the adaptability to real-time conditions is improved, but the use of energy for processing and playback control increases

Engineering Contradiction:

Improveadaptability to real-time conditionsVSAvoiduse of energy for processing and playback control

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic action by updating the music playlist and playback settings at specific intervals rather than continuously. The detection modules sample user situation parameters at predetermined time intervals, and the playlist is regenerated periodically based on accumulated data, rather than making constant real-time adjustments. This reduces processing frequency and energy consumption while still maintaining adaptability to changing user conditions.

Inventive Principle:

Principle #19Periodic action

AI summary

A music play method includes detecting at least one group of dynamic parameters of an electronic device and obtaining detected dynamic parameters. Once a music playlist of the electronic device is determined to be adjusted according to the detected dynamic parameters, the music play is adjusted according to the detected dynamic parameters and an adjusted music playlist is obtained.
