Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a cost-effective and efficient method for healthcare providers without expertise in ear disorders to diagnose hearing loss and refer patients to specialized hearing health specialists, as current tools are expensive, labor-intensive, and often lead to delayed diagnosis and treatment.
Innovation Solution
A system and method that enables healthcare providers to administer a portable, interactive hearing assessment using a computer-readable medium, including a hearing test with pure tone frequencies and a pressure test, which provides a baseline indication of hearing issues and recommends further analysis by qualified specialists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current hearing assessment tools are used, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The hearing assessment is divided into multiple independent tests (pure tone hearing test, pressure test, speech recognition test) that can be administered separately. Each test evaluates a specific aspect of hearing function, allowing the overall assessment to be broken down into manageable components that can be performed by general healthcare providers without requiring complex integrated equipment.
Solution Approach 2:
The patent introduces a computer-readable medium with programmed instructions that acts as an intermediary between the healthcare provider and the complex hearing assessment procedures. This software-based intermediary guides the provider through simplified versions of the assessment, translating complex measurement requirements into straightforward user actions while maintaining assessment accuracy.
2Measurement precision
If comprehensive hearing assessment is performed, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary screening using simple pure tone hearing tests and pressure tests before proceeding to more comprehensive speech recognition tests. This staged approach allows the assessment to adapt its complexity based on initial findings, avoiding time-consuming comprehensive testing when simpler tests suffice for diagnosis.
Solution Approach 2:
The assessment protocol is dynamic rather than static, allowing the healthcare provider to adjust the depth and scope of testing based on preliminary results and clinical judgment. The system can progress from basic hearing threshold measurements to comprehensive speech evaluation only when necessary, optimizing the time spent on each patient.
3Ease of operation
If hearing assessment is made accessible to general healthcare providers, then ease of operation is improved, but measurement precision may worsen
Solution Approach 1:
The computer-readable medium provides self-service guidance for the healthcare provider, with programmed instructions that automatically guide the assessment process, interpret results, and determine when referral is needed. The system performs its own calibration and quality control, reducing the need for provider expertise while maintaining consistent, accurate measurements.
Solution Approach 2:
The system incorporates real-time feedback mechanisms that guide the healthcare provider through the assessment process, providing immediate guidance on proper testing procedures and interpretation of results. This feedback loop ensures that even providers without specialized training can perform accurate assessments by receiving continuous directional input from the system.
4Ease of operation
If simplified hearing assessment is used, then ease of operation is improved, but loss of information increases
Solution Approach 1:
The assessment divides hearing evaluation into distinct functional categories (pure tone thresholds, pressure test results, speech recognition scores), providing detailed information about specific hearing abilities while keeping each individual test simple. This segmentation allows comprehensive information gathering through multiple straightforward tests rather than one complex test.
Solution Approach 2:
The system adds the dimension of multiple assessment dimensions (air conduction, bone conduction, speech, pressure) to provide comprehensive hearing information. By measuring hearing across different dimensions and modalities, the system captures complete hearing status information while keeping each individual measurement simple and easy to administer.
