Rotary Earhanger Structure With Auto-Reset Wearing Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earphones are inconvenient to operate when worn due to the need for manual adjustment of the earhanger unit, which reduces user experience.
Innovation Solution
A rotary earhanger structure with a movable connection sleeve and elastic member that allows for automatic adjustment and resetting of the earhanger unit, facilitated by inclined surface portions and a sliding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the earhanger unit uses a rotatable connection structure, then the adaptability to different ear shapes is improved, but the ease of operation deteriorates because manual adjustment is required while wearing
Solution Approach 1:
The earhanger unit automatically adjusts and locks into position through the interaction between the inclined surface and elastic member without requiring user intervention. The structure uses the ear's own shape to trigger the automatic adjustment mechanism, eliminating the need for manual operation while maintaining adaptability to different ear configurations
Solution Approach 2:
The elastic member is pre-loaded to store potential energy, and the inclined surface is pre-configured at a specific angle. When the earhanger contacts the ear, these pre-prepared elements automatically engage to adjust the connection angle before the user completes the wearing action, enabling seamless adaptation without requiring subsequent manual adjustment
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
Simplifies user operation by enabling automatic resetting and clamping of the earhanger unit, improving the overall wearing experience.
Implementation Method 1
the movable connection sleeve is connected with an elastic member for driving the movable connection sleeve to move in a direction close to the earhanger unit
Implementation Method 2
one end of the earhanger unit is provided with a first inclined surface portion extending obliquely in a preset rotational direction, and the movable connection sleeve is provided with a second inclined surface portion cooperatively connected with the first inclined surface portion

AI summary
A rotary earhanger structure of a wireless earphone includes an earhanger unit and a movable connection sleeve rotationally connected therewith. One end of the earhanger unit includes a first inclined surface portion extending obliquely in a preset rotational direction. The movable connection sleeve has a second inclined surface portion cooperatively connected with the first inclined surface portion. The movable connection sleeve is connected with an elastic member for driving the movable connection sleeve in a direction close to the earhanger unit. The external force rotates the earhanger unit in the preset rotating direction to adjust the wearing angle. When the earhanger unit is not subjected to the external force, the movable connection sleeve moves in the direction close to the earhanger unit under the force of the elastic member, so that the automatic reset function after the earhanger rotation is realized, thereby simplifying user operation and improving user experience.
