Earphone Hook Design for Stable Attachment Without Ear Canal Blockage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earphones often cover the external ear canal, compromising comfort and increasing the risk of traffic accidents due to restricted hearing.
Innovation Solution
The earphone design features a hook-shaped component that hangs between the ear's rear side and the head, a connecting component that extends from the head, and a holding component that contacts the ear's front side, providing a pressing force to secure the earphone without covering the external ear canal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the earphone covers the external ear canal to secure attachment, then the stability is improved, but the user's hearing of ambient sounds is blocked causing safety issues
Solution Approach 1:
The earphone structure is divided into separate functional components: a hook-shaped component for rear ear attachment, a connecting component, and a holding component for front ear contact. This segmentation allows the earphone to attach securely to the ear's outer structure without needing to cover the ear canal, thus maintaining stability while preserving ambient sound hearing.
2Object-affected harmful factors
If the earphone uses a simple over-ear design, then the ambient sound hearing is maintained, but the attachment stability is insufficient
Solution Approach 1:
The earphone transitions from a two-dimensional planar attachment (over-ear) to a three-dimensional spatial configuration by extending the hook-shaped component along the ear's curvature from the rear side to the front side. This dimensional change enables the earphone to wrap around the ear's轮廓, creating multiple contact points that significantly enhance attachment stability while keeping the ear canal open.
3Stability of the object's composition
If the earphone uses a complex structure to improve attachment stability, then the stability is improved, but the device complexity increases
Solution Approach 1:
The earphone integrates the attachment function into a single continuous structure consisting of the hook-shaped component, connecting component, and holding component. This merged design achieves stable attachment through the integrated three-component system without requiring additional separate fastening mechanisms, thus improving stability while controlling structural complexity.

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.
