Patent 9221397 was granted and assigned to Google on December, 2015 by the United States Patent and Trademark Office.
Aspects of the present disclosure relate to an apparatus providing a first component having a circular opening with an interior chaffered edge and a second component positioned within the circular opening. The apparatus also provides a magnetic feature at a circular bottom surface of the first component, where the magnetic feature provides a magnetic pull force in a first direction to secure the second component within the circular opening. The second component is configured to break away from the circular opening when a contact force to the breakaway component causes a force in a second direction opposite of the first direction and greater than the magnetic pull force.
