Active-Vent Earpiece Fit for Smaller Ear Canals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing devices often fail to fit properly in smaller ear canals and extend outward, compromising comfort and aesthetics, while also lacking optimal sound quality for both external and internal audio sources.
Innovation Solution
A hearing device with an earpiece design that includes a vent mechanism positioned distally, allowing for reduced size and improved fit in smaller ear canals, and features that enhance sound quality by selectively opening and closing vent paths for different audio environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the vent mechanism is positioned proximal to the receiver, then the device can be made compact, but the device extends outward from the ear canal reducing comfort and aesthetics
Solution Approach 1:
The vent mechanism is repositioned from a proximal location to a distal location along the longitudinal axis of the earpiece, utilizing the length dimension of the ear canal to accommodate the vent without increasing the radial profile or extending outward from the ear. This dimensional rearrangement allows the vent to be positioned deeper in the ear canal where it does not compromise comfort or aesthetics while maintaining compact overall device dimensions.
2Adaptability or versatility
If the device is made smaller to fit smaller ear canals, then fit is improved, but the vent mechanism becomes difficult to position effectively
Solution Approach 1:
By positioning the vent mechanism distally along the longitudinal axis rather than proximally, the design accommodates smaller ear canal dimensions without compromising vent functionality. The distal positioning utilizes the available length of the ear canal to house the vent mechanism effectively, allowing the device to fit smaller ear canals while maintaining proper vent placement and function.
3Device complexity
If the vent mechanism is fixed in position, then the structure is simple, but sound quality cannot be optimized for different audio environments
Solution Approach 1:
The vent mechanism is designed with movable components that can dynamically adjust the vent path opening in response to different audio environments. This dynamic adjustment capability allows optimization of sound quality for various conditions (such as music playback with bass enhancement versus environmental sound) while maintaining a relatively simple overall structure through the use of spring-loaded or diaphragm-based mechanisms that automatically respond to pressure differentials.
