Bidirectional Earpiece Stabilizer for Left-Right Ear Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earpieces for left and right ears are mirror-symmetric but not identical, leading to increased manufacturing costs and user confusion due to the need to identify the earpiece's orientation before wearing.
Innovation Solution
A bendable stabilizer element that can be oriented clockwise or counterclockwise to fit either ear, allowing for a single design compatible with both left and right ears, and optionally featuring symmetric apertures and recesses for enhanced flexibility and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mirror-symmetric stabilizer designs are used for left and right ears, then earpieces can be manufactured separately for each ear, but manufacturing cost and complexity increase
Solution Approach 1:
The stabilizer element is designed with bidirectional bendability, allowing a single earpiece design to fit both left and right ears. The stabilizer can be bent clockwise or counterclockwise to accommodate the cymba concha area of either ear, eliminating the need for separate left and right earpiece designs and reducing manufacturing complexity.
2Reliability
If mirror-symmetric stabilizer designs are used for left and right ears, then separate earpieces can be manufactured, but user confusion increases due to the need to identify earpiece orientation
Solution Approach 1:
The stabilizer element's bidirectional bendability allows users to wear the same earpiece on either ear without confusion about orientation. Users can simply bend the stabilizer in the desired direction (clockwise or counterclockwise) to fit their ear, eliminating the need to identify or sort earpieces by ear orientation.
3Device complexity
If a single earpiece design is used for both ears, then manufacturing complexity is reduced, but the stabilizer must be bendable in both clockwise and counterclockwise directions
Solution Approach 1:
The stabilizer element is designed with dynamic bendability, allowing it to change its shape and orientation. The stabilizer can be bent clockwise or counterclockwise to adapt to the anatomical differences between left and right ears, providing versatility while maintaining a single unified design.
Solution Approach 2:
The stabilizer element incorporates asymmetric bend characteristics that allow it to be bent in both clockwise and counterclockwise directions. This asymmetric design enables the stabilizer to adapt to the specific anatomical requirements of either ear while maintaining a single universal earpiece structure.

Function Achieved in This Case
Reduces manufacturing complexity and user confusion by enabling a single earpiece design for both ears, improving ease of use and comfort.
Implementation Method 1
a stabilizer element extending from the body portion, the stabilizer element being bendable in both a clockwise direction and a counterclockwise direction with respect to a central axis of the sound passage

AI summary
A device for transmitting sound to an ear canal includes a body portion, and a stabilizer element extending from the body portion. The stabilizer element is bendable in both a clockwise direction and a counterclockwise direction with respect to a central axis of a sound passage formed in the body portion, so as to contact with a cymba concha area of an ear to stabilize the device to the ear. In this way, an earpiece including the device may be worn on both a left ear and a right ear of a human, thereby reducing manufacture cost and complexity and improving user experience.
