Solution Overview

Problem

Conventional auditory prosthesis fitting techniques rely heavily on clinician expertise and are inefficient, as they employ a 'one-size-fits-all' approach, which can lead to suboptimal results and is problematic due to the shortage of trained clinicians, especially in geographic areas with limited resources.

Innovation Solution

An individualized fitting system that uses recipient-specific data to automatically generate and display a tailored fitting interface, reducing the reliance on clinician skill by streamlining the process and focusing on clinically relevant settings and measurements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional one-size-fits-all fitting techniques are used, then the fitting process can be performed by any clinician, but the fitting results are suboptimal and the process is inefficient

Engineering Contradiction:
Improvefitting precisionVSAvoidfitting efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The system performs preliminary analysis of recipient-specific data (audiograms, hearing loss type, residual hearing) before the fitting process begins. This pre-analysis automatically determines the appropriate fitting approach and parameters, so that when the clinician begins the fitting session, the optimal settings and workflow are already prepared, eliminating the need for time-consuming manual assessment and ensuring consistent precision regardless of clinician experience.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts fitting parameters based on the analyzed recipient-specific data. Different hearing loss types (conductive, sensorineural, mixed), degrees of hearing loss, and residual hearing levels trigger automatic modification of fitting parameters and workflows. This ensures each recipient receives a customized fitting protocol rather than a generic one, improving precision while the automation maintains efficiency.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If comprehensive fitting assessments are performed for all recipients, then accurate individualized fitting can be achieved, but the time required for fitting sessions increases

Engineering Contradiction:
Improvefitting accuracyVSAvoidfitting session duration
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system extracts and analyzes recipient-specific data (audiograms, hearing loss characteristics, residual hearing levels) before the fitting session to pre-determine the appropriate assessment protocol. Based on this extraction, the system automatically selects only the necessary tests and measurements required for that specific recipient type, eliminating unnecessary assessments. This ensures fitting accuracy is maintained while significantly reducing the time spent on routine or irrelevant testing.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs exactly the right amount of assessment - no more, no less - based on recipient classification. For example, recipients with certain hearing loss patterns may require full comprehensive assessment, while others with clear-cut patterns may only need targeted measurements. The automation ensures each recipient receives the appropriate level of assessment depth, avoiding both over-assessment (wasting time) and under-assessment (compromising accuracy).

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If automated individualized fitting is implemented, then fitting efficiency and consistency improve, but the system complexity increases

Engineering Contradiction:
Improvefitting throughputVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system introduces an automated software intermediary that handles the complex data analysis and decision-making processes. This software layer sits between the recipient data and the fitting process, automatically interpreting audiograms, classifying hearing loss types, and determining appropriate fitting parameters. This intermediary handles the complexity internally while presenting a simplified interface to the clinician, maintaining high throughput without requiring the clinician to understand or manage the underlying system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs self-configuration and self-optimization based on recipient data. It automatically adjusts fitting parameters, selects appropriate workflows, and adapts to different recipient types without requiring manual programming or complex clinician intervention. This self-service capability handles the system complexity automatically, allowing the system to maintain high productivity while the complexity is managed autonomously rather than requiring complex user management.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If manual fitting expertise is relied upon, then flexible individualized care can be provided, but the shortage of trained clinicians limits access especially in resource-limited areas

Engineering Contradiction:
Improveindividualized care qualityVSAvoidclinician accessibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system replaces the need for manual clinician expertise with an automated computational system. Instead of relying on trained clinicians to manually assess and fit each recipient, the system uses automated algorithms to analyze recipient data, determine hearing loss characteristics, and generate individualized fitting protocols. This substitution maintains high-quality individualized care while making the service accessible to any location with the device, eliminating the barrier of clinician availability and expertise shortages.

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

Solution Approach 2:

The system segments the fitting process into distinct automated stages: data collection, data analysis, recipient classification, parameter determination, and fitting execution. Each segment is handled automatically based on objective criteria rather than subjective clinician judgment. This segmentation allows the system to provide consistent individualized care quality while requiring minimal clinician involvement, making the service accessible in resource-limited areas where trained clinicians are scarce.

Inventive Principle:
Principle #1Segmentation

AI summary

Embodiments of the present invention are generally directed to individualized (recipient-specific) techniques for fitting an auditory/hearing prosthesis to a recipient. In the individualized fitting techniques, a fitting system obtains data/information that is specific to the recipient to which the auditory prosthesis is being fitted. The fitting system is configured to analyze the recipient-specific data and to generate an individualized fitting plan/program that is specifically tailored to the recipient.
