Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hearing aid fittings are performed by professionals in clinical settings, then measurement precision and reliability are improved, but device complexity and ease of operation worsen due to limited accessibility
Solution Approach 1:
The system enables consumers to perform their own hearing aid fittings at home using a portable OAE measurement device and smartphone application. Users independently complete otoacoustic emissions testing, receive automated fitting recommendations, and adjust their hearing aids without requiring professional audiologist assistance, thus making the service accessible while maintaining measurement quality through standardized protocols and automated analysis.
Solution Approach 2:
The patent replaces the traditional mechanical/clinical fitting system with an automated digital system. Instead of manual audiometric testing equipment in a clinic, the system uses a portable OAE device connected to a smartphone, with automated signal processing, database matching, and fitting parameter generation, eliminating the need for physical clinic visits while maintaining measurement accuracy.
2Ease of operation
If basic adjustments are provided for personal sound amplification products, then ease of operation is improved, but manufacturing precision and adaptability worsen due to limited customization options
Solution Approach 1:
The system incorporates real-time feedback loops where users can test different fitting parameters, evaluate their effectiveness through immediate auditory feedback, and iteratively adjust settings. The system also provides feedback on OAE measurement results and compares user responses against normative data, enabling users to achieve personalized optimizations beyond basic pre-programmed settings.
Solution Approach 2:
The fitting system transitions from static pre-programmed settings to dynamic, user-adapted configurations. Users can modify fitting parameters in real-time based on their specific needs and environmental conditions, with the system providing guided adjustments that adapt to individual hearing characteristics and preferences, enabling continuous optimization rather than fixed configurations.
3Measurement precision
If traditional audiogram-based tuning is used, then measurement precision is improved, but loss of time increases due to required clinical visits
Solution Approach 1:
The system substitutes traditional audiogram-based tuning with otoacoustic emissions measurement. Instead of requiring clinic-based pure-tone audiometry equipment and professional administration, the portable OAE device performs objective hearing threshold assessment at home, with automated signal processing and interpretation that eliminates the need for professional time while maintaining diagnostic accuracy through validated measurement protocols.
Solution Approach 2:
The system performs preliminary hearing assessment and fitting recommendation generation before the user needs to make adjustments. By completing the OAE measurement and generating fitting parameters in advance at home, the system eliminates the need for subsequent clinical visits for initial fitting, saving time while ensuring accurate baseline measurements are obtained before customization begins.
