Pivoting Hearing Device Earpiece for Even Clamping Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headsets and hearing devices often fail to fit various user ear shapes comfortably, leading to discomfort and instability over time due to uneven pressure distribution.
Innovation Solution
A hearing device with pivotably attached earpieces, allowing a distance of 5-15 mm from the pivot hinge to the primary surface, enabling even clamping force distribution and improved fit, and featuring pivot hinges with stopping elements for controlled rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the earpiece is rigidly attached to the headband, then the structure is simple and stable, but the device cannot adapt to different user ear shapes and angles
Solution Approach 1:
The patent applies the dynamics principle by replacing the rigid attachment with a pivot hinge that enables rotational movement. The earpiece can rotate relative to the headband to adapt to different user ear shapes and angles, transforming the static structure into a dynamic one that adjusts to varying conditions while maintaining structural simplicity.
2Stability of the object's composition
If the clamping force is increased to improve stability, then the device stays in place better, but the user experiences discomfort and pressure on the ear
Solution Approach 1:
The pivot hinge enables the earpiece to dynamically adjust its position and orientation to match the user's ear shape. This dynamic adaptation allows the device to achieve stable positioning through geometric alignment rather than excessive clamping force, thereby reducing pressure and discomfort on the user's ear while maintaining stability.
3Length of moving object
If the distance from the pivot hinge to the primary surface is increased, then the earpiece has more clearance, but the clamping force distribution becomes uneven
Solution Approach 1:
The patent applies parameter changes by optimizing the distance parameter from the pivot hinge to the primary surface within a specific range (5-15 mm). This parameter optimization ensures that the earpiece maintains adequate clearance for rotation and adjustment while achieving even clamping force distribution across the contact surface, balancing both requirements through precise dimensional control.

AMENDMENTS TO THE ABSTRACTPlease amend the Abstract of the Disclosure as follows:Disclosed is a hearing device. The hearing device is configured to be worn on a user's head. The hearing device comprises a first earpiece configured to be worn at an ear of the user. The first earpiece comprises a primary surface . The primary surface is configured to face the user's ear when the user is wearing the hearing device in its intended position. The hearing device further comprises an earpiece support. The earpiece support is configured to rest on the user's head. The earpiece support has a first end and a second end. The first earpiece is pivotably attached to the first end of the earpiece support by means of a first pivot hinge, such that a distance (A) from the first pivot hinge to the primary surface of the first earpiece is in the range of about 5 mm to 15 mm. Thereby an even distribution of a clamping force is applied on the primary surface of the first earpiece when the user is wearing the hearing device in its intended position.
