Solution Overview

Problem

Existing audio enhancement methods for hearing impairments are subjective and unstable, failing to provide personalized and effective sound adjustments for individuals with varying degrees of hearing loss.

Innovation Solution

An audio enhancement method that objectively categorizes hearing impairments through big data analysis of hearing test data, determining specific audio enhancement modes to adjust loudness, tone, and clarity, and selecting a target mode based on processed audio quality or user features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If subjective audio enhancement methods are used, then the audio can be adjusted to some extent, but the enhancement is unstable and not personalized

Engineering Contradiction:
Improveaudio enhancement stabilityVSAvoidpersonalization capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system changes audio parameters (loudness, tone, timbre, clarity) based on objective hearing impairment categories derived from hearing test data. Different audio enhancement modes adjust specific parameters according to the user's hearing profile, providing stable and personalized enhancement results.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces subjective manual adjustment with objective automated classification using big data analysis of hearing test data. The system automatically determines hearing impairment categories and selects appropriate audio enhancement modes, eliminating subjectivity and improving stability.

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

2Adaptability or versatility

If multiple audio enhancement modes are provided, then personalized enhancement can be achieved, but the system complexity increases

Engineering Contradiction:
Improvepersonalization capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The audio enhancement system is segmented into multiple predefined modes corresponding to different hearing impairment categories. Each mode is optimized for specific hearing loss patterns, allowing the system to handle diversity through structured segmentation rather than complex unified processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses a universal framework where a single audio enhancement apparatus can serve multiple functions by switching between different enhancement modes. The same hardware processes different audio profiles by applying mode-specific parameter adjustments, eliminating the need for separate devices for different hearing impairments.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If automated mode selection is implemented, then the ease of operation improves, but the measurement and detection difficulty increases

Engineering Contradiction:
Improveuser operation simplicityVSAvoidhearing impairment detection complexity
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The system performs self-service by automatically analyzing hearing test data and selecting appropriate enhancement modes without requiring manual user input. The automated detection and classification processes handle the complexity internally, presenting a simple user interface while managing the measurement and detection challenges through programmed algorithms.

Inventive Principle:
Principle #25Self-service
