Solution Overview

Problem

Existing in-ear communication devices face stability and comfort issues due to varying ear sizes and shapes, as they do not adapt effectively to different users, leading to instability and discomfort.

Innovation Solution

An in-ear communication device equipped with a compression strut that fits into the lower concha of the ear and extends across the crus of the helix, exerting pressure under the antihelix to securely hold the device in place, using a mechanical spring mechanism for stability and adjustability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a one-size-fits-all earphone design is used, then manufacturing cost and simplicity are improved, but stability and comfort deteriorate due to varying ear sizes and shapes

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoiddevice stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The earphone system is divided into two separate components: a universal earphone unit and an individualized stabilizer component. The stabilizer is segmented to fit specific anatomical features of the user's ear (antihelix, crus of helix, concha), allowing customization for stability while keeping the main earphone unit standardized for easy manufacturing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stabilizer acts as an intermediary component between the universal earphone and the user's ear. It mediates the connection by adapting to individual ear anatomy and providing the necessary stabilization, while the earphone itself remains a standardized, easily manufacturable unit.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If stabilization devices are added to hold the headset in place, then device stability is improved, but device complexity and comfort deteriorate

Engineering Contradiction:
Improvedevice stabilityVSAvoidstabilization structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The stabilizer incorporates a compression spring that provides dynamic, adjustable stabilization. The spring mechanism allows the stabilizer to adapt to different ear sizes and shapes automatically, providing the necessary stabilization force without requiring complex adjustment mechanisms or multiple size variants.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The compression spring changes its compression parameter based on the individual ear's anatomy, automatically adjusting the stabilization force and position. This parameter adaptation provides effective stabilization across different users without increasing structural complexity.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If current stabilization techniques are used, then some stability is achieved, but user adaptation and comfort deteriorate due to lack of adaptability to different ear sizes

Engineering Contradiction:
Improvedevice stabilityVSAvoiduser adaptation
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The stabilizer is designed with different structural features at different locations to interact with specific anatomical features of the ear. The upper portion engages with the antihelix and crus of helix, while the lower portion engages with the concha, providing localized adaptation to individual ear anatomy for both stability and comfort.

Inventive Principle:
Principle #3Local quality

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution provides a comfortable, secure, and adaptable fit for different ear sizes, ensuring the device remains stable and comfortable, allowing for single-handed insertion and adjustment, enhancing user experience.

Implementation Method 1

The compression spring, when extended across the crus of the helix of the human ear, fits securely under the antihelix in the upper concha of the ear. The compression spring exerts outward pressure against the antihelix of the ear, when under compression, thereby comfortably holding the in-ear device in place through pressure on the lower and upper concha of the human ear.

AI summary

An in-ear stabilizer with a compression strut securely holds an in-ear communications device within the human ear. The in-ear stabilizer comprises an in-ear device housing which fits into the human ear and has a receiver and speaker. Attached to the in-ear device housing is a compression strut which extends, when in the human ear, across the crus of helix and fits securely under the antihelix in the upper concha of the ear. The housing of the in-ear device fits into the lower concha of the human ear. The compression strut exerts outward pressure when compressed, comfortably holding the in-ear device in place through pressure on the lower and upper concha of the human ear.
