Hearing Device Reversible Frame Lock for Power Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing devices, particularly in-ear hearing aids, face challenges in maintenance and replacement due to the integration of power modules with wireless charging capabilities, which often require complex and bulky designs.
Innovation Solution
The hearing device incorporates a reversible frame lock mechanism that allows for easy removal and replacement of the power module without damaging the device, utilizing an electronic frame and holding fingers to secure components in multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power module is integrated with wireless charging capabilities, then wireless energy reception is enabled, but the device becomes more complex and bulky
Solution Approach 1:
The power module is designed as a separate, removable component that can be detached from the hearing device. This segmentation allows the wireless charging functionality to be added without permanently integrating it into the main device structure, thereby reducing overall device complexity while maintaining adaptability.
Solution Approach 2:
The power module is made dynamically removable and replaceable through a simplified connection mechanism. This dynamic design allows users to attach or detach the power module as needed, providing flexibility without requiring complex permanent integration structures.
2Ease of repair
If the power module is made removable for maintenance and replacement, then ease of repair is improved, but the fixing mechanism becomes more complex
Solution Approach 1:
The complex locking mechanism is extracted and replaced with a simple snap-fit connection system. This allows the power module to be easily removed and reattached without requiring sophisticated locking mechanisms, thereby improving ease of repair while minimizing the addition of complexity.
Solution Approach 2:
Traditional mechanical locking systems with multiple components are replaced with a simplified elastic finger-based snap-fit mechanism. This substitution reduces the number of moving parts and simplifies the overall fixing mechanism while maintaining secure attachment during use.
3Volume of moving object
If miniaturization is pursued to reduce conspicuousness, then device size is reduced, but maintenance accessibility is worsened
Solution Approach 1:
The hearing device is segmented into a main body and a separate power module. This segmentation allows the overall device volume to be minimized for inconspicuous wear, while the separated power module provides accessible maintenance points that can be easily reached and manipulated despite the compact size.
