Open-Ear Earphone Hook Structure for Stable Canal-Free Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earphones often cause discomfort and instability due to improper fitting, particularly covering the external ear canal and not accommodating the unique anatomical features of individual ears, leading to potential health issues and reduced comfort.
Innovation Solution
An earphone design featuring a hook-shaped component that hangs between the ear and head, a connecting component extending to the head, and a holding component that contacts the front side of the ear, utilizing elastic metal wires and a multi-section structure to provide a pressing force, allowing the earphone to be worn without covering the external ear canal and enhancing comfort and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional earphone designs are used to ensure stable wearing, then the earphone can be securely held, but the external ear canal is covered causing discomfort and potential health issues
Solution Approach 1:
The earphone is divided into three functional segments: a hook-shaped component for rear ear engagement, a connecting component for structural linkage, and a holding component for front ear contact. This segmentation allows each part to perform its specific function independently, enabling the earphone to stabilize without covering the ear canal.
Solution Approach 2:
The design extracts the ear canal coverage function entirely, replacing it with a hook-based suspension system. The holding component contacts only the front side of the ear (concha area), while the hook-shaped component engages the rear side, completely removing the harmful effect of ear canal occlusion while maintaining wearing stability.
2Strength
If a fixed rigid structure is used to ensure structural strength, then the earphone maintains its shape, but it cannot accommodate various ear shapes and sizes
Solution Approach 1:
The connecting component incorporates elastic metal wires that provide flexibility and adaptability. These elastic elements allow the earphone to dynamically adjust to different ear shapes and sizes while maintaining sufficient structural strength for stable wearing. The elasticity enables the structure to deform slightly to accommodate anatomical variations.
Solution Approach 2:
The design changes the physical parameters of the connecting component by using elastic metal wires with specific mechanical properties. This allows the structure to transition between rigid and flexible states, providing both strength for stability and adaptability for different ear anatomies.
3Ease of manufacture
If the earphone structure is simplified to reduce complexity, then manufacturing becomes easier, but the ability to provide even weight distribution and prevent slippage is reduced
Solution Approach 1:
The earphone is segmented into three distinct components that can be manufactured separately using simple processes, then assembled together. This segmentation maintains manufacturing simplicity while enabling complex functionality for weight distribution and slip prevention through the coordinated action of hook-shaped, connecting, and holding components.
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 improves wearing comfort by liberating the external ear canal, increasing contact area with the ear, and distributing weight evenly, reducing the risk of slippage, and accommodating various ear shapes and sizes through adjustable components.
Implementation Method 1
an elastic metal wire may be arranged inside the hook-shaped component
Implementation Method 2
the hook-shaped component may form a lever structure with the first contact point as a fulcrum

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.
