Solution Overview

Problem

Conventional earphones often compromise on comfort and stability due to inadequate fitting, leading to discomfort and potential dislodging during use, especially when trying to avoid blocking the external ear canal.

Innovation Solution

The earphone design incorporates a hook-shaped component, a connecting component, and a holding component that work together to provide a pressing force on the ear, utilizing an elastic metal wire and adjustable structures to ensure a secure fit without blocking the ear canal, allowing for comfortable wear and reliable sound transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the earphone uses a simple design without hook-shaped component, then the device complexity is reduced, but the stability and comfort of wearing deteriorate

Engineering Contradiction:
Improvestructure complexityVSAvoidwearing stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The earphone is divided into multiple functional components: a hook-shaped component for stability, a holding component for sound transmission, and a connecting component for flexibility. This segmentation allows each part to perform its specific function optimally while maintaining overall wearing stability without excessive complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hook-shaped component extends into a third dimension by wrapping around the ear, creating a spatial structure that provides stability. This dimensional approach allows the earphone to secure itself on the ear without requiring complex adjustment mechanisms or multiple fastening points.

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

2Stability of the object's composition

If the earphone blocks the external ear canal to improve fit, then the wearing stability is improved, but the sound quality and comfort deteriorate

Engineering Contradiction:
Improvewearing stabilityVSAvoidsound transmission quality
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The earphone structure separates the stabilizing function (hook-shaped component wrapping around the ear) from the sound transmission function (holding component positioned in front of the ear canal). This segmentation allows the earphone to remain stable without blocking the ear canal, preserving both comfort and sound quality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The holding component acts as an intermediary element that provides sufficient contact with the ear for stability while maintaining a non-blocking relationship with the ear canal. It mediates between the need for secure fitting and the need for unobstructed sound transmission.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the earphone uses rigid structure to ensure stability, then the wearing stability is improved, but the comfort and adaptability deteriorate

Engineering Contradiction:
Improvewearing stabilityVSAvoidadaptability to different ears
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The connecting component introduces dynamic flexibility to the earphone structure, allowing it to adapt to different ear shapes and sizes. This flexible connection enables the rigid hook-shaped and holding components to adjust their relative positions, providing both stability and adaptability across different users.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connecting component functions as a flexible element that can bend and conform to different ear geometries. This flexibility allows the earphone to maintain stable contact points while adapting to various ear shapes, improving both comfort and universal applicability.

Inventive Principle:
Principle #30Flexible shells and thin films

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 design ensures a stable and comfortable fit by distributing the weight evenly and using elastic components to clamp the ear securely, preventing the earphone from slipping while allowing for unobstructed ear canal access, enhancing both comfort and sound quality.

Implementation Method 1

an elastic metal wire may be arranged inside the hook-shaped component

Methodology Applied
Scientific EffectElasticity: Elasticity

Implementation Method 2

the hook-shaped component may form a lever structure with the first contact point as a fulcrum. A force directed to the outside of the head and provided by the head at the second contact point may be transformed into a force directed to the head at the first connection point by the lever structure

Methodology Applied
Scientific EffectLever: Lever

AI summary

The present disclosure discloses an earphone. The earphone may include a hook-shaped component, a connecting component, and a holding component. When the earphone is in a wearing state, the hook-shaped component may be configured to hang between a rear side of an ear of a user and a head of the user. The holding component may be configured to contact a front side of the ear. The connecting component may be configured to connect the hook-shaped component and the holding component and extend from the head to an outside of the head to cooperate with the hook-shaped component to provide the holding component with a pressing force on the front side of the ear.
