Detachable Hearing Aid Holder for Secure Fit and Mic Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hearing aids worn between the auricle and the head are less conspicuous but lack versatility in appearance and functionality for different situations, limiting user engagement and comfort.
Innovation Solution
A hearing aid design featuring a detachable holder with a fitting portion that attaches to a stepped portion on the main body, allowing for interchangeable holders made of various materials and designs to suit different activities and aesthetics, ensuring secure attachment and unhindered sound collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hearing aid is worn between the auricle and the head, then it is less conspicuous and can be used with relatively little resistance, but it lacks versatility in appearance and functionality for different situations
Solution Approach 1:
The hearing aid is divided into two separate components: a main body and a holder. The holder can be detached and replaced with different types (e.g., hooks, clips, bands) to adapt to different wearing situations and personal preferences, while the main body remains unchanged. This segmentation allows versatility without complicating the core device structure.
Solution Approach 2:
The main body is designed with a universal interface (stepped portion) that can accommodate multiple types of holders. This allows a single main body to serve multiple functions by simply changing the holder, enabling the same device to be worn in various ways (over-the-ear, behind-the-ear, on-the-go) without requiring multiple different hearing aid units.
2Adaptability or versatility
If a detachable holder is provided to enable easy exchange for different situations, then versatility is improved, but the risk of loss or misplacement increases
Solution Approach 1:
The holder is designed to fit over the main body in a nested configuration, with the attaching portion extending from the holder and wrapping around or securing to the main body. This nested structure ensures that the holder remains firmly attached during use but can be easily removed when needed, balancing security with ease of exchange.
Solution Approach 2:
The holder is configured to wrap around the main body or follow its contours, creating a secure fit through curved geometry. This curvature ensures the holder stays in place during movement while still allowing simple attachment and detachment actions.
3Reliability
If the holder is designed to wrap around the main body, then secure attachment is achieved, but the area covering the microphone increases
Solution Approach 1:
The holder is designed to wrap around specific portions of the main body that do not interfere with the microphone opening. The attaching portion secures to areas such as the housing edges or non-microphone surfaces, ensuring secure attachment while leaving the microphone area completely exposed and accessible for sound collection.

AI summary
A sound processing apparatus includes: a main body in which one side surface comes into contact with an ear when worn; and a holder which is detachable from the main body, wherein, the main body is provided with a stepped portion on an outer peripheral edge of an other side surface different from the one side surface in contact with the ear, and the holder includes a fitting portion fitted in the stepped portion and an attaching portion attached to the ear.
