Solution Overview

Problem

Existing audio devices cannot automatically adjust volume to meet the individual hearing conditions of different users, leading to inconvenience and wear on remote controllers due to random environmental noise variations.

Innovation Solution

An audio device and method that obtain user identity information, detect environmental volume, and determine user hearing conditions to adjust volume accordingly, using a relationship between user hearing conditions, environmental volume, and target volume, with optional distance detection for further adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual volume adjustment is used, then users can control audio output, but repeated adjustments cause inconvenience and wear on remote controller

Engineering Contradiction:
Improvevolume adjustment convenienceVSAvoidtime for repeated adjustments
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs self-service by automatically detecting environmental noise levels and adjusting volume without user intervention. The audio device monitors ambient sound through its microphone and autonomously modifies playback volume based on detected noise conditions, eliminating the need for manual remote controller operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback by continuously monitoring environmental noise levels through the microphone and using this information to dynamically adjust volume. The detected ambient sound serves as feedback that triggers automatic volume compensation, creating a closed-loop control system that adapts to changing acoustic environments.

Inventive Principle:
Principle #23Feedback

2Extent of automation

If volume is adjusted according to environmental noise only, then automatic adjustment is achieved, but individual hearing conditions of different users are not considered

Engineering Contradiction:
Improveautomatic volume adjustmentVSAvoidadaptation to individual hearing conditions
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The system applies local quality by customizing volume adjustment parameters for each individual user based on their specific hearing characteristics. Different users can have personalized profiles that account for their unique hearing sensitivities, allowing the same environmental noise condition to result in different volume adjustments for different users.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system implements dynamics by making volume adjustment adaptable and changeable based on both environmental conditions and user-specific factors. The volume control is not fixed but dynamically adjusts according to real-time noise detection combined with stored user hearing profile data, allowing the system to respond differently to the same environmental condition for different users.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If distance between user and audio device is not considered, then volume adjustment is simplified, but users at different distances experience inconsistent audio levels

Engineering Contradiction:
Improvevolume control system complexityVSAvoidaudio level accuracy for different users
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system replaces mechanical distance measurement with acoustic field analysis by using the microphone to detect environmental noise levels. Instead of physically measuring user distance, the system infers distance-related information from the characteristics of ambient sound detection, substituting a mechanical sensing approach with an acoustic sensing approach.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
