Solution Overview

Problem

Existing hearing aid systems require users to visit a hearing professional for adjustments, which is inconvenient for those with limited mobility, in remote areas, or in developing countries, and do not allow for autonomous parameter adjustments based on individual hearing experiences.

Innovation Solution

A system and method enabling users to autonomously adjust hearing aid parameters using artificial intelligence, utilizing a mobile device microphone to record environmental sounds, and conducting hearing tests with headphones or earbuds to determine suitable settings, which can be uploaded to a cloud for processing and downloaded to the user's device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If users visit a hearing professional for adjustments, then hearing aid parameters can be professionally adjusted, but it causes inconvenience, expense and time consumption associated with travel to a remote location

Engineering Contradiction:

Improvehearing aid parameter adjustment accuracyVSAvoiduser accessibility

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The hearing aid system performs self-adjustment of parameters using an integrated hearing test and processing unit. The system conducts a hearing test, processes the results to determine optimal parameters, and automatically adjusts the hearing aid settings without requiring users to visit a hearing professional, thereby enabling autonomous parameter optimization while eliminating travel requirements

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical process of physical visits to hearing professionals with a digital/electronic system. A processing unit analyzes hearing test data and automatically generates parameter adjustments, substituting the manual professional fitting process with an automated electronic system that can be performed remotely

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If hearing tests are conducted with external sounds present, then environmental context is captured, but external sounds interfere with the accuracy of hearing test results

Engineering Contradiction:

Improveenvironmental adaptabilityVSAvoidhearing test accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system converts the presence of environmental sounds from a harmful interference into a beneficial feature. By recording ambient noise levels during the hearing test and using this information to adjust the test parameters and compensate for background noise, the system actually improves the accuracy of hearing assessments conducted in real-world environments rather than requiring silent chambers

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The hearing aid system continuously monitors the environmental sound level during testing and uses this feedback to dynamically adjust test parameters. The processing unit analyzes ambient noise characteristics and modifies the hearing test accordingly, creating an adaptive testing procedure that maintains accuracy despite varying environmental conditions

Inventive Principle:

Principle #23Feedback
