Hearing Aid Parameter Adjustment via Memory Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hearing aid adjustment methods require individual parameter adjustments for each ambient setting, leading to inefficiencies and difficulties in equipping small hearing aids with volume controls, as they do not allow for collective changes or easy switching between settings.
Innovation Solution
A hearing aid adjusting apparatus with an input device, storage, controller, and display that enables selection and collective conversion of parameters across multiple settings using a memory switching button, allowing for duplication, movement, and volume adjustments without individual parameter changes, improving convenience and wear comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual parameter adjustments are made for each ambient setting, then each setting can be precisely optimized, but adjustment time increases significantly
Solution Approach 1:
The system pre-configures multiple ambient settings (e.g., quiet place, noisy place, car interior) with optimized parameters in advance. During fitting, the practitioner can select from these pre-prepared settings rather than creating them from scratch, significantly reducing adjustment time while maintaining precision.
Solution Approach 2:
The system allows copying of parameter sets between ambient settings. A practitioner can duplicate a base setting and modify it for specific conditions, or copy successful settings between patients. This eliminates redundant adjustment work while preserving precise parameter configurations.
2Ease of operation
If a volume switch is added to the hearing aid body for individual volume adjustment, then user convenience improves, but the device size increases making it difficult to equip small hearing aids
Solution Approach 1:
The volume control function is extracted from the hearing aid body and implemented as a separate wireless communication module in the fitting apparatus. The hearing aid receives volume control commands wirelessly, eliminating the need for a physical volume switch on the device while maintaining user convenience.
Solution Approach 2:
A wireless communication intermediary (practitioner's computer or mobile device) mediates between the user's volume adjustment needs and the hearing aid. Volume commands are transmitted wirelessly through this intermediary, allowing volume control without physical buttons on the hearing aid itself.
3Adaptability or versatility
If multiple ambient settings are configured with different gain parameters, then hearing performance across different environments improves, but the complexity of managing and switching between settings increases
Solution Approach 1:
The ambient setting system serves multiple functions simultaneously: it stores gain parameters, provides setting names for easy identification, enables rapid switching between environments, and allows copying/modification of settings. This multi-functionality reduces the perceived complexity by consolidating various management tasks into a unified system.
Solution Approach 2:
The system dynamically adapts to user needs by allowing flexible switching between predefined ambient settings based on current environment. The settings can be activated on-demand rather than requiring manual configuration each time, making the system adaptable without increasing operational complexity.
