Earbud Case Electromagnet Release for Easier Device Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional earbuds and hearing aids are difficult to remove from their cases for users with decreased dexterity due to their small form factor and the use of permanent magnets, which restrict movement and require overcoming strong magnetic attractions.
Innovation Solution
An ear worn device system featuring a capacitive, mechanical, or inductive switch that alters the activation state of an electromagnet within the case, reducing magnetic attraction to facilitate easy removal by changing the magnetic coupling between the device and its case.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent magnets are used to restrain the ear worn device in the case, then the device is securely held and movement is prevented, but users with decreased dexterity find it difficult to remove the device due to strong magnetic attraction
Solution Approach 1:
The patent applies the dynamics principle by replacing static permanent magnets with a dynamic electromagnet system. The electromagnet can be activated or deactivated based on user input, allowing the magnetic restraint to be temporary rather than permanent. This enables the device to be securely held during storage while allowing easy removal when needed, resolving the contradiction between reliable restraint and ease of operation.
Solution Approach 2:
The patent applies parameter changes by controlling the electrical current to the electromagnet to adjust the magnetic field strength. By changing the activation state of the electromagnet through a switch, the magnetic attraction parameter can be modified from strong (when activated) to weak or zero (when deactivated), enabling both secure restraint and easy removal of the device.
2Volume of moving object
If the ear worn device is made small to fit comfortably in the ear canal, then it provides good fit and comfort, but users with decreased dexterity have difficulty gripping and removing it from the case
Solution Approach 1:
The patent applies mechanics substitution by replacing the purely mechanical gripping and removal action with an electromechanical system. Instead of relying solely on user manual manipulation of a small device, the system uses an electromagnet actuated by a switch (which can be operated with less dexterity) to assist in the removal process, reducing the mechanical effort required by the user.
Solution Approach 2:
The dynamic electromagnet system allows the case to actively assist in device removal rather than requiring passive user effort. When the user activates the switch, the electromagnet deactivates, and the device can be easily removed or even ejected, compensating for the small size that makes manual gripping difficult.
3Stability of the object's composition
If permanent magnets are used to maintain device position in the case, then device stability is improved, but the magnetic attraction requires excessive force to overcome for removal
Solution Approach 1:
The patent replaces static permanent magnets with a dynamic electromagnet system that can adjust its magnetic field strength. This allows the system to provide strong magnetic attraction for stable device positioning during storage, while enabling easy removal by deactivating the electromagnet through user input, thus reducing the force required for removal.
Solution Approach 2:
By controlling the electrical current to the electromagnet, the magnetic field parameter can be changed from a strong attractive state (for stability) to a weak or zero magnetic state (for easy removal). This parameter control through switch activation resolves the contradiction between maintaining stable position and minimizing removal force.

AI summary
A system, including: an ear worn device configured to provide audio to a user's ear; a switch configured to receive physical contact from the user and, in response, alter an activation state of the switch; and a case configured to receive the ear worn device when not in use, wherein the case includes an electromagnet configured to magnetically attract the ear worn device, wherein changing the activation state of the switch causes the electromagnet to reduce attraction to the ear worn device to allow the user to more easily remove the ear worn device from the case.
