Hearing Device Chassis Attachment System for Sealing Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing devices face issues with leaking gaps when assembling the chassis, which affects the integrity of the sound hook or corda adaptor attachment, and there is a need for a versatile chassis that can be used across different housing designs.
Innovation Solution
A hearing device design featuring a chassis with attachment structures for the first and second shell members, where the chassis is surrounded by these shell members, utilizing pinholes and pins for secure fixation, allowing for easy assembly and use across various designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the chassis is assembled by wedging it into a basis structure so that the chassis is floating, then the assembly process is simple, but a leaking gap is created between the sound hook/corda adaptor and the receiver suspension
Solution Approach 1:
The housing is divided into a first shell member and a second shell member that can be assembled in different configurations. The chassis can be attached to either shell member independently, allowing the system to be segmented and reconfigured without compromising the sealing integrity between components.
Solution Approach 2:
The chassis is designed with a universal attachment structure that can be used with different shell members and configurations. The basis structure with recess and attachment features serves multiple functions: providing structural support, enabling secure attachment, and maintaining sealing integrity across different housing designs.
2Adaptability or versatility
If a sound hook or corda adaptor is attached to the housing and chassis, then the functionality is enhanced, but the chassis and suspension are pushed back creating a leaking gap
Solution Approach 1:
The basis structure is pre-configured with a recess and attachment features that anticipate the attachment of sound hooks or corda adaptors. This preliminary structural preparation ensures that when components are attached, the chassis and suspension remain properly positioned without being pushed back, thereby maintaining sealing integrity.
Solution Approach 2:
The basis structure acts as an intermediary element between the shell members and the chassis. It provides a stable mounting platform with recesses that accommodate the chassis while preventing it from being pushed back during component attachment, thus mediating between the attachment requirements and the sealing requirements.
3Adaptability or versatility
If different housing designs are created, then the adaptability is improved, but the chassis assembly complexity increases
Solution Approach 1:
The chassis and basis structure are designed as universal components that can be used across multiple housing designs. The standardized attachment structures, recesses, and features allow the same chassis to be assembled with different first and second shell members, enabling housing design variety without increasing chassis assembly complexity.
