Earphone Stabilizer with Pivotable Retention Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless earphones often fall out during exercise due to inadequate fit, and existing stabilizers are prone to damage and loss from repeated use and installation.
Innovation Solution
An adjustable stabilizer integrated into the earphone main body, pivotably or slidably positioned to securely press against the conchal wall, preventing dislodgment and assembled to minimize damage and loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate stabilizer or flexible hook is attached to the earphone, then the earphone can be secured in the ear, but the stabilizer is prone to damage and loss from repeated removal and installation
Solution Approach 1:
The stabilizer is integrated with the earphone main body through a rotatable connection mechanism, merging two previously separate components into a unified structure. This integration eliminates the need for repeated attachment and detachment, thereby preventing damage and loss while maintaining the stabilizing function.
Solution Approach 2:
The stabilizer is designed with rotatable joints that allow it to move between different positions (stored position covering part of the main body contour and sticking out position extending from the main body). This dynamic capability enables the stabilizer to adapt to different wearing conditions while remaining firmly connected to the main body, avoiding the damage associated with repeated assembly and disassembly.
2Reliability
If the stabilizer is integrated into the main body, then damage and loss are reduced, but the earphone size and complexity increase
Solution Approach 1:
The stabilizer is designed to nest against the contour of the main body when in the stored position, with part of the stabilizer covering part of the main body contour. This nesting arrangement minimizes the overall size increase when the stabilizer is integrated into the main body, reducing the visual and spatial complexity while maintaining the integrated structure.
3Force
If the stabilizer extends from the main body, then securing force against the conchal wall increases, but the earphone profile becomes larger
Solution Approach 1:
The stabilizer can dynamically extend from the main body to the sticking out position when securing force is needed, and retract to the stored position when not in use. This dynamic extension and retraction allows the earphone to maintain a compact profile during storage while providing adequate stabilizing force during wear, effectively resolving the contradiction between force and dimension.

AI summary
An earphone includes a main body and a stabilizer. The stabilizer is movably disposed on the main body and has a stored position and at least one sticking out position. When the stabilizer is in the stored position, the stabilizer covers part of a contour of the main body. When the stabilizer is in the at least one sticking out position, part of the stabilizer sticks out the main body and is spaced apart from the main body by a specific distance.
