Flex Connector for Hearing Aid Receiver Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing assistance devices face challenges in achieving precise alignment and repeatable performance due to anatomical variations, making it difficult to create a reliable connector scheme for receivers.
Innovation Solution
A flex connector system, including a bendable flex tab connector and a receptacle connector with a laminated epoxy glass stiffener, enables quick and reliable connection and disconnection of the receiver module to the hearing aid circuitry at various degrees of vertical axial alignment, eliminating the need for solder pads and allowing for customization and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional connectors with solder pads are used, then precise alignment is required, but manufacturing complexity and production time increase
Solution Approach 1:
The patent changes the physical parameters of the connector by replacing rigid solder pads with a flexible printed circuit board that can bend and deform. This flexibility allows the connector to accommodate anatomical variations in ear canal shapes without requiring precise alignment, thereby resolving the contradiction between manufacturing precision and device complexity
Solution Approach 2:
The flexible printed circuit board introduces dynamic capability to the connector system. The PCB can dynamically adjust its shape and position to match different ear canal anatomies, eliminating the need for fixed precise alignment while reducing manufacturing complexity
2Reliability
If custom connectors are designed for each anatomical variation, then repeatable performance is achieved, but production time and costs increase
Solution Approach 1:
The flexible printed circuit board serves as a universal connector that can adapt to multiple different anatomical configurations. Instead of designing custom connectors for each variation, the single flexible PCB design can accommodate all ear canal shapes, achieving repeatable performance across different users while maintaining high productivity
Solution Approach 2:
The patent employs a flexible printed circuit board as the connector medium. This thin, flexible film can be bent and shaped to match various ear canal anatomies, providing a universal solution that maintains reliable electrical connections without requiring custom manufacturing for each case
3Stability of the object's composition
If rigid connectors are used, then structural stability is maintained, but adaptability to anatomical variations is reduced
Solution Approach 1:
The flexible printed circuit board replaces rigid connectors with a flexible thin film that can bend and conform to different ear canal shapes. This maintains structural stability for electrical connections while providing the necessary adaptability to various anatomical variations
Solution Approach 2:
The flexible printed circuit board is typically constructed from composite materials that combine flexibility with electrical conductivity and structural integrity. This composite structure enables both stability for reliable connections and adaptability for different anatomies
