Solution Overview

Problem

Conventional audio playback systems require manual adjustment of EQ settings by users, which is inconvenient and inefficient, especially when switching between different application programs.

Innovation Solution

An intelligent audio playback system that automatically adjusts EQ settings based on the application program being executed by the computing device, transmitting the appropriate EQ settings to the audio output device for immediate sound output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual EQ adjustment is used in conventional audio playback systems, then users can control sound settings, but user convenience deteriorates and operation time increases

Engineering Contradiction:

Improveuser convenienceVSAvoidtime for manual adjustment

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The audio playback system automatically detects the current application program and retrieves the corresponding EQ settings without requiring user intervention. The system serves itself by autonomously matching applications with their optimal sound profiles, eliminating manual adjustment needs and improving user convenience while reducing time loss

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

EQ settings are pre-configured and stored in the system for various application programs before actual use. When an application is launched, the system has already prepared the corresponding EQ parameters, enabling immediate automatic application without requiring real-time user adjustment, thus saving time and improving ease of operation

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If automatic EQ adjustment is implemented, then user convenience improves, but system complexity increases

Engineering Contradiction:

Improveautomatic EQ adjustmentVSAvoidsystem structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system continuously monitors which application program is currently executing and uses this feedback information to automatically select and apply the corresponding EQ settings. This feedback mechanism enables automatic adaptation without requiring complex user interfaces or manual configurations, achieving automatic adjustment through intelligent system monitoring

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The audio playback system integrates multiple functions into a single unified mechanism: application detection, EQ setting retrieval, and automatic parameter application. This multi-functional approach consolidates what could be separate complex components into one cohesive system, achieving automatic EQ adjustment without proportionally increasing overall system complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An audio playback system includes an audio output device and a computing device. The computing device executes an application program. A sound signal corresponding to the application program and an EQ setting are transmitted from the computing device to the audio output device. After the sound signal and the EQ setting from the computing device are received by the audio output device, the audio output device outputs sound according to the EQ setting.
