Ear-Wing Fixing Stability and Pressure Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional earphones with uniform eartips struggle to securely fit different ear structures, leading to discomfort due to compression on the antitragus and tragus, especially during extended wear.
Innovation Solution
An ear wing design featuring a deformable fixing portion that conforms to the antihelix, a coupling portion rotatably attached to the sound output device, and a variable portion that adjusts shape to minimize pressure on the antitragus and tragus, using elastic materials for improved comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer leg and inner leg are extended to contact the antitragus and tragus for fixing the earpiece, then the earpiece can be securely fixed to the external ear, but the pressure on the antitragus and tragus increases causing discomfort during long wear
Solution Approach 1:
The ear wing is divided into multiple functional segments: a first leg extending to the antitragus, a second leg extending to the tragus, and a bridge connecting them. This segmentation allows each part to independently contact different ear structures, providing stable fixation while distributing pressure across multiple contact points rather than concentrating it on single sensitive areas.
Solution Approach 2:
The bridge portion is specifically designed with a curved shape that locally adapts to the contour of the external ear. This local quality adjustment allows the bridge to conform to the ear's natural shape, providing comfortable pressure distribution in the region between the antitragus and tragus while maintaining overall fixing stability.
2Ease of manufacture
If uniform eartips are used for all users, then the manufacturing is simple, but the earphones cannot be securely fixed to ears with different structures
Solution Approach 1:
The ear wing incorporates flexible legs and a curved bridge that can dynamically adapt to different ear shapes and structures. The flexibility allows the ear wing to bend and conform to various ear contours, providing secure fixation for users with different ear types while maintaining a relatively simple manufacturing process compared to custom-molded solutions.

AI summary
The present invention relates to an ear wing including: a coupling portion coupled to a sound output device; a deformable fixing portion deformed with a curvature to correspond to the shape of the antihelix in such a manner as to be located inside the antihelix and for fixing the position of the coupling portion to an external ear; and a variable portion for connecting the coupling portion and the deformable fixing portion in such a manner as to support the deformable fixing portion thereagainst and having at least one or more variable parts changed in shape according to the deformation of the deformable fixing portion. In addition, according to the present invention, the pressure applied to the surrounding portions of the antitragus and the tragus can be minimized through the structure of connecting the coupling portion and the variable portion, so that wearing comfort becomes excellent, and even if the user wears the ear wing for long hours, he or she does not feel uncomfortable, thus optimizing the conveniences in use.
