Modular Hearing Aid Faceplate with Detachable Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing aid faceplates are not versatile enough to accommodate different microphone types and are typically designed for specific ear sides, limiting flexibility in production and user compatibility.
Innovation Solution
A modular faceplate arrangement with a receiving portion and a detachable faceplate module housing that includes an electronic circuit, allowing for adjustable microphone positioning and easy swapping of microphone types, enabling the same faceplate to be used for both ears and accommodating various ear canal shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed faceplate design is used, then manufacturing is simple, but versatility for different microphone types and ear sides is limited
Solution Approach 1:
The faceplate is divided into two separate components: a base faceplate and a detachable faceplate module. The module can be removed and replaced to accommodate different microphone types and ear configurations, enabling versatility without permanently complicating the overall structure.
Solution Approach 2:
The faceplate transitions from a static, fixed design to a dynamic, reconfigurable system. The detachable module allows the faceplate configuration to change based on requirements, providing adaptability while maintaining structural simplicity when not in use.
2Adaptability or versatility
If different faceplates are used for different microphone types, then microphone requirements are met, but production costs increase
Solution Approach 1:
By separating the microphone-containing module from the base faceplate, the system allows standardized mass production of the base faceplate while enabling customization through interchangeable modules. This reduces overall production costs compared to manufacturing entirely different faceplates for each microphone type.
Solution Approach 2:
The base faceplate is designed as a universal platform that can accommodate multiple types of faceplate modules. This multi-functionality allows a single base design to support various microphone configurations, reducing the need for multiple unique faceplate designs and lowering production costs.
3Adaptability or versatility
If the microphone position is fixed on the faceplate, then manufacturing is straightforward, but adaptability to different ear canal shapes is limited
Solution Approach 1:
The microphone position is made adjustable through the detachable module design. The module can be positioned at different locations on the base faceplate or oriented in different directions, allowing adaptation to various ear canal shapes without requiring a completely fixed, complex positioning mechanism built into the base structure.
