Solution Overview

Problem

Existing earpieces fail to provide a universal fit for ears of varying sizes and shapes, leading to discomfort and instability.

Innovation Solution

A universal earpiece design featuring a retaining body that fits within the concha of the ear and a projection element that extends into the ear canal, allowing rotation for secure engagement with the antihelix, antitragus, or tragus to achieve a stable and comfortable fit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional earpiece designs are used, then the earpiece can be manufactured with simple structures, but the earpiece fails to provide a universal fit across varying ear sizes and shapes

Engineering Contradiction:
Improveuniversal fitVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The earpiece employs a universal retaining body design that can accommodate different ear sizes and shapes through a single standardized structure. The retaining body features a concha-engaging surface and ear canal opening that universally fit various ear anatomies, eliminating the need for multiple sized earpieces while maintaining secure retention across different users.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If the earpiece structure is simplified, then manufacturing becomes easier, but the earpiece becomes unstable and uncomfortable for extended wear

Engineering Contradiction:
ImprovestabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The retaining body is designed to be rotatable within the concha, allowing dynamic adjustment to achieve optimal engagement. This rotational capability enables the earpiece to adapt to slight variations in ear anatomy while maintaining stable retention, and the dynamic engagement mechanism ensures comfortable wear by allowing the user to find the perfect fit position.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The earpiece is divided into distinct functional segments: a retaining body for concha engagement and a projection element for ear canal occlusion. This segmentation allows each component to be optimized independently - the retaining body for stable concha fit and the projection element for effective ear canal blocking - while maintaining overall structural simplicity.

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If the projection element is made longer to block more external sound, then sound blocking effectiveness improves, but the earpiece becomes more prone to slipping and loss

Engineering Contradiction:
Improveexternal sound blockingVSAvoidretention reliability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The projection element extends in a direction perpendicular to the main body axis, projecting outward from the retaining body to occlude the ear canal opening. This dimensional arrangement allows effective sound blocking without increasing the length of the retaining body portion that engages the concha, thereby preventing slipping while maintaining sound blocking effectiveness.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A universal earpiece, and methods of making and using such an earpiece, whereby the earpiece includes a retaining body, and a projection element outwardly extending from the retaining body. When a wearer wears the earpiece, the retaining body is configured to dispose within the concha of an ear of a wearer, and the projection element is configured for projecting into the ear canal opening of the wearer. Upon rotation of the earpiece, the retaining body fixedly engages with the concha to retain the projection element within the ear canal opening.
