Abstract

Disclosed is a magnet design that includes a girdle positioned at the center of polarity of the magnet. This design enables the use of one type of magnet for both positive and negative poles, which reduces manufacturing costs.

Title

Magnet Girdle

Abstract Statement

Disclosed is a magnet design that includes a girdle positioned at the center of polarity of the magnet. This design enables the use of one type of magnet for both positive and negative poles, which reduces manufacturing costs.

Problem Addressed 

Auditory prosthesis sound processors use magnets for retention. The magnets come in different strengths. Reverse polarity magnets are also used for rare cases in which a corresponding implanted magnet has flipped.

To avoid re-surgery, a reverse polarity magnet is typically used. But the cost of having such reverse polarity magnets manufactured in low volume is high. A design is needed to reduce manufacturing cost of reverse polarity magnets.  

Novelty Statement

The novel solution is a magnet design that includes a girdle.

Description (Components, Process)

The girdle is positioned at the center of polarity of the magnet. The girdle incorporates locking features that allows the magnet to be inserted in the sound processor in any polarity.

Benefits and Advantages

The girdle enables the use of one type of magnet for both positive and negative poles; therefore, manufacturers do not need to keep separate ‘reverse polarity magnets’, which reduces costs.
