Solution Overview

Problem

Users experience unclear and muffled sound during prolonged Bluetooth headset calls due to individual hearing losses at specific frequency points, affecting the call experience.

Innovation Solution

A Bluetooth headset with earphone components that generate a monaural hearing loss curve for each ear based on a hearing loss test, compensating the original audio signal to improve clarity and adjust volume according to personal hearing profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standard audio signal is used for Bluetooth headset calls, then general audio broadcasting is achieved, but users with hearing loss experience unclear and muffled sound

Engineering Contradiction:
Improvecall audio clarityVSAvoidpersonalized hearing compensation
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by customizing audio compensation parameters according to each user's specific hearing loss characteristics at different frequency points. The system generates personalized compensation curves that adjust audio signals locally at frequencies where the user has hearing deficiencies, rather than applying uniform audio processing to all users.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements parameter changes by modifying audio signal parameters (gain, frequency response) based on measured hearing loss data. The system dynamically adjusts compensation parameters according to the user's hearing profile, transforming the standard audio signal into a customized compensated signal that accounts for individual hearing variations.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If personalized audio compensation is implemented, then auditory experience is improved, but system complexity increases due to hearing loss testing and curve generation

Engineering Contradiction:
Improveauditory experienceVSAvoidhearing loss test and compensation system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies self-service by enabling the system to automatically perform hearing loss testing, generate compensation curves, and adjust audio parameters without requiring external intervention. The Bluetooth headset autonomously completes the entire process of hearing assessment and audio customization, reducing the need for manual configuration or professional audiologist involvement.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements preliminary action by conducting hearing loss testing and generating compensation curves in advance before actual audio communication occurs. The system prepares personalized audio profiles beforehand, so that when calls or audio playback occurs, the compensation is already in place, eliminating the need for real-time adjustment during usage.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If monaural hearing loss testing is performed for each ear, then accurate personalized compensation is achieved, but testing time and process complexity increase

Engineering Contradiction:
Improvehearing loss measurement accuracyVSAvoidhearing loss test duration
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies segmentation by dividing the hearing loss measurement process into separate monaural tests for each ear. Instead of attempting to measure bilateral hearing simultaneously, the system isolates and tests each ear independently, generating separate hearing loss curves for the left and right ears. This segmentation improves measurement accuracy while allowing the testing to be conducted in manageable stages.

Inventive Principle:
Principle #1Segmentation
