Abstract

Today, the current trend for Behind-The-Ear (BTE) hearing instruments is to have a customizable color changing concept to emphasize individual design options. For example, the outer shell or housing of the BTE hearing instrument can be changed to other colors by the end user. This is made possible by a so called top-down housing design. The top and bottom housing shells of the BTE hearing instrument are attached to the main hearing instrument corpus via so called axles. However, insertion of these axles into the respective holes is often problematic, because the small axle sizes hinder an easy handling. Currently, these axles are inserted by a pair of tweezers or a removal tool. The user has to manually place the fine axles on the tip of the tool to subsequently carefully insert the axle into the BTE hearing instrument housing.

Axle Insertion Tool for Hearing Instruments

Idea: Julin Teo, SG-Singapore; Chua Miang Tze, SG-Singapore

Today, the current trend for Behind-The-Ear (BTE) hearing instruments is to have a customizable color changing concept to emphasize individual design options. For example, the outer shell or housing of the BTE hearing instrument can be changed to other colors by the end user. This is made possible by a so called top-down housing design. The top and bottom housing shells of the BTE hearing instrument are attached to the main hearing instrument corpus via so called axles. However, insertion of these axles into the respective holes is often problematic, because the small axle sizes hinder an easy handling. Currently, these axles are inserted by a pair of tweezers or a removal tool. The user has to manually place the fine axles on the tip of the tool to subsequently carefully insert the axle into the BTE hearing instrument housing.

In the following a novel tool, the so called axle insertion tool, is proposed which allows a quick and easy solution for users to remove, store and insert the axles of hearing instruments. The axle insertion tool consists of an internal holding chamber which stores the axles. This chamber provides a storage space for these axles to avoid a misplacement of the axles. An internal mechanism guides and pushes one axle at a time from the holding chamber into the BTE by means of activating a button at the top of the tool. The internal mechanism that pushes each axle forward is similar to that of known mechanical pencils. If an axle has to be inserted into the BTE, the axle is gripped at the right spot by a spring- holder placed at the dispensing tip. (see Figure 1). The movements of the holders are controlled by a button at the top end of the proposed axle insertion tool. When the button is pressed, the spring compresses, the holder opens up and releases the axle. When the button is released, the spring causes the holders to close up, thus gripping the axle in place. The pressing and releasing movement of the button pushes the axle gradually forward and thereby the axle is aligned and inserted into the BTE.

The proposed axle insertion tool allows for asse...
