Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hearing aid programming connectors require significant force to engage and often have mechanical details that make it difficult to attach when the hearing aid is in the user's ear, necessitating additional engagement mechanisms.
Innovation Solution
The proposed solution involves a programming interface for hearing aids that allows for easy alignment and retention of a programming connector with minimal force, eliminating the need for additional engagement mechanisms by using a design with a primary and secondary receiving portion that deform to retain the connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional programming connectors are used, then reliable electrical connection is achieved, but significant force is required to engage and mechanical orientation details make it difficult to attach when hearing aid is in ear
Solution Approach 1:
The patent replaces traditional mechanical connector systems with a deformable receiving portion that uses elastic deformation to engage the programming connector. Instead of requiring significant insertion force to overcome mechanical barriers, the receiving portion deforms elastically to accommodate and retain the connector, substantially reducing the force required for engagement while maintaining secure connection.
Solution Approach 2:
The patent changes the physical state and mechanical properties of the receiving portion by using deformable, elastic materials with specific durometer ranges (40-70 Shore A). This parameter change allows the receiving portion to transition from a rigid, force-requiring structure to a compliant, easy-to-engage structure that can deform and recover to secure the programming connector.
2Reliability
If conventional connectors with engagement mechanisms are used, then secure retention is achieved, but device complexity increases due to additional mechanisms
Solution Approach 1:
The patent extracts and eliminates the door or latch mechanism from the hearing aid housing by integrating the retention function directly into the deformable receiving portion. The receiving portion itself provides both the entry pathway and the retention mechanism through its elastic deformation characteristics, removing the need for separate engagement components and simplifying the overall device structure.
Solution Approach 2:
The patent merges the functions of the receiving portion, retention mechanism, and electrical contact into a single integrated component. The deformable receiving portion simultaneously provides mechanical guidance, secure retention through elastic deformation, and electrical connectivity, eliminating the need for separate door mechanisms, latches, and contact elements.
3Manufacturing precision
If traditional programming connectors are used, then electrical connection is established, but alignment difficulty increases when hearing aid is within ear canal
Solution Approach 1:
The patent employs asymmetric design in the programming connector and receiving portion, where the connector has a specific non-symmetric shape that corresponds to the asymmetric geometry of the receiving portion. This asymmetric configuration provides natural alignment cues that guide the connector into the correct orientation during insertion, eliminating the need for complex alignment procedures when the hearing aid is in the ear canal.
Solution Approach 2:
The patent incorporates preliminary alignment features in the programming connector design, such as pre-positioned contact points and guiding surfaces, that automatically align the connector with the receiving portion before electrical contact is made. This preliminary action ensures proper alignment occurs naturally during the insertion process, reducing the skill and precision required by the user.
