Hearing Aid Plug Connector Receiver Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Behind-the-ear hearing aids with receivers firmly connected to the housing present difficulties in replacement and versatility, as the receiver's size limits options and makes changing configurations cumbersome.
Innovation Solution
A plug connector system where the receiver is securely attached to the plug connector rather than the housing, allowing for easy removal and replacement, enabling the hearing aid to function as both a behind-the-ear and receiver-in-canal device by switching modules, thereby increasing user flexibility and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the receiver is firmly connected to the housing, then the structural stability is improved, but the ease of replacement and versatility deteriorates
Solution Approach 1:
The hearing aid is divided into separate modular components: the housing and the receiver assembly (plug connector + receiver). The receiver is firmly connected to the plug connector, while the plug connector connects to the housing via a releasable connection. This segmentation allows the receiver to be stably mounted while enabling easy replacement by disconnecting the plug connector from the housing.
2Reliability
If the receiver is firmly connected to the housing, then the reliability is improved, but the adaptability and versatility deteriorates
Solution Approach 1:
The connection between the plug connector and housing is designed to be dynamically changeable - firmly connected during operation for reliability, but easily disconnectable for replacement or configuration changes. This dynamic connection state allows the system to switch between stable operation and flexible reconfiguration.
Solution Approach 2:
The plug connector is designed as a universal interface that can connect to different housing types or configurations. The same receiver assembly with plug connector can be used with different housings or sound tube configurations, enabling the hearing aid to function in multiple modes (behind-the-ear, receiver-in-canal) and increasing versatility.
3Stability of the object's composition
If the receiver is accommodated in the housing, then the structural integrity is improved, but the ease of operation and handling deteriorates
Solution Approach 1:
The receiver assembly is segmented from the housing as a separate module connected via plug connector. This allows the receiver to be handled and replaced independently without manipulating the entire housing, significantly improving ease of operation while maintaining structural integrity when connected.
4Ease of manufacture
If the receiver is firmly connected to the housing, then the manufacturing simplicity is improved, but the loss of time for replacement increases
Solution Approach 1:
The modular design with plug connector creates a standardized interface that simplifies both manufacturing (standardized components) and replacement (quick connect/disconnect). The releasable connection enables rapid replacement without complex assembly/disassembly procedures, reducing replacement time while maintaining manufacturing simplicity through standardized parts.

AI summary
A hearing aid, in particular a behind-the-ear hearing aid, has a housing to be worn behind an ear of a user, and a receiver which, in order to transmit sound to the ear, is connected to a sound tube having a housing-side end on which a plug connector is arranged. The plug connector is connected releasably to the housing. The hearing aid is characterized in that the plug connector contains a holder for the receiver, and the receiver is a component part of the plug connector.
