Solution Overview

Problem

Existing hearing device filters are small and difficult to exchange, requiring special tools and professional assistance, making it inconvenient for users to replace them.

Innovation Solution

A user-replaceable element with a physical filter that can be attached to the hearing device housing, allowing users to exchange it easily with their fingers without tools, providing protection against earwax, water, and dirt.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If prior art filters are used, then protection against earwax, water and dirt is provided, but the filters are small and difficult to exchange requiring special tools

Engineering Contradiction:

ImproveEase of filter exchangeVSAvoidFilter size and exchange mechanism complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The filter is integrated into a separate exchangeable element that can be independently removed and replaced from the hearing device housing. This segmentation allows the filter to be exchanged without affecting other components and enables users to replace it without special tools by simply detaching and attaching the element.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The filter is extracted from the housing as a separate exchangeable element rather than being permanently integrated. This allows the filter to be removed and replaced independently, making it accessible to users for easy maintenance without requiring professional assistance or special tools.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If prior art filters are used, then protection against earwax, water and dirt is provided, but professional assistance is required for exchange

Engineering Contradiction:

ImproveUser self-exchange capabilityVSAvoidProfessional assistance requirement

Core Design Contradiction:

Ease of operationVSEase of repair

Solution Approach 1:

The exchangeable element is designed with user-friendly attachment and detachment mechanisms that allow users to perform filter replacement themselves without needing professional assistance. The element can be easily grasped and manipulated with fingers, enabling independent maintenance by the user.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If the element is made small to fit the hearing device, then it integrates well, but it becomes difficult to grip and exchange with fingers

Engineering Contradiction:

ImproveFinger grippabilityVSAvoidElement dimensions

Core Design Contradiction:

Ease of operationVSLength of stationary object

Solution Approach 1:

The element incorporates a retention member that extends in a direction perpendicular to the main body of the element. This dimensional extension provides a grip surface that is easily accessible to user fingers while keeping the main body compact enough to fit within the hearing device housing.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
