Solution Overview

Problem

Conventional hearing aid fitting devices require a lengthy process due to the need for repeated recombination and mutation of parameters using interactive genetic algorithms, making the adjustment process time-consuming for both technicians and users.

Innovation Solution

A hearing aid fitting device with a hierarchically classified database that stores adjustment data by similarity, allowing for efficient selection and application of fine adjustment data through a user-friendly interface, reducing the number of listening comparisons needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If interactive genetic algorithm is used to allow users to perform adjustment themselves, then ease of operation is improved, but adjustment time increases significantly

Engineering Contradiction:

Improveease of adjustmentVSAvoidadjustment time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary classification and ranking of adjustment data before the user needs to make adjustments. By pre-organizing the data structure and pre-calculating potential adjustments, the system reduces the time required for actual user interaction while maintaining ease of operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates and presents multiple copies of adjusted hearing aid parameters to the user for comparison. Instead of requiring the user to perform complex adjustment operations, the system generates and displays multiple preset adjustment options that the user can select from, reducing both the complexity of operation and the time required.

Inventive Principle:

Principle #26Copying

2Manufacturing precision

If repeated recombination and mutation operations are performed to converge on optimal parameters, then manufacturing precision of fitting is improved, but adjustment time increases

Engineering Contradiction:

Improvefitting precisionVSAvoidadjustment time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The adjustment process is segmented into discrete, pre-defined categories and levels. Instead of performing continuous recombination and mutation operations, the system divides the adjustment space into manageable segments (classification levels) that can be navigated systematically, reducing the time required to achieve precise fitting.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system replaces the mechanical iterative process of recombination and mutation with a more efficient data-driven approach. By using pre-classified adjustment data and intelligent search algorithms, the system achieves precise fitting without requiring repeated manual or automated trial-and-error operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
