Flex-Based Connector for Hearing Aid Programming and DAI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical connectors for data transfer in electronic devices, such as hearing aids, are typically large and bulky, requiring multiple connectors that occupy valuable space and complicate user management.
Innovation Solution
A multi-pin flex-based electrical plug and socket system that can function as both a programming and Direct Audio Input (DAI) connector depending on orientation, utilizing a flex circuit wrapped around a structural housing with sculpted flex bumps and a spring feature for secure contact, allowing a single connector to serve dual purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electrical connectors are incorporated into the hearing aid for programming and Direct Audio Input, then the hearing aid can perform multiple functions, but the space inside the hearing aid is consumed and users need to keep track of numerous different plugs
Solution Approach 1:
The patent implements a universal connector design where a single physical connector can serve multiple functions (programming and Direct Audio Input) by changing its orientation. The connector includes contacts that can be electrically connected to different circuits depending on whether the connector is inserted in a first orientation (programming mode) or a second orientation (DAI mode), eliminating the need for multiple separate connectors and reducing internal space requirements.

3Reliability
If traditional large and bulky electrical connectors are used for data transfer, then reliable electrical connection is achieved, but valuable space inside the hearing aid is occupied
Solution Approach 1:
The patent employs a flex circuit as the connector structure, which uses a flexible printed circuit board with conductive traces and contacts. This flexible film-based approach provides reliable electrical connections while occupying significantly less space than traditional rigid connectors. The flex circuit can be configured to make contact with corresponding contacts in the hearing aid housing when inserted, ensuring dependable electrical connectivity for both programming and DAI functions.

AI summary
Described herein is a multi-pin flex-based electrical plug and socket that can be incorporated into a hearing aid and be used to serve two purposes depending on the orientation with which the plug is inserted into the socket. For example, the plug may be inserted into the socket in a first orientation (e.g., right-side up) for programming the hearing aid and inserted in a second orientation (e.g., upside down) for inputting a DAI signal. In an alternate embodiment, the plug and socket forms a both-ways-okay connector such that the plug can be inserted in a either a first orientation or a second orientation (e.g., either right-side up or upside down) and still function.
