Abstract

Small devices like hearing aids need battery power to operate. When the battery compartment is open for removing the battery, the battery can fall out in a specific direction. This direction is usually designed pointing up in normal usage. In order to prevent unintended dropping out of the battery, an additional part working as a flexible holder is used in existing solutions.

Battery Fixation

Idea: Volker Goly, DE-Erlangen; Werner Fickweiler, DE-Erlangen; Thorsten Neumann, DE- Nuremberg

Small devices like hearing aids need battery power to operate. When the battery compartment is open

for removing the battery, the battery can fall out in a specific direction. This direction is usually

designed pointing up in normal usage. In order to prevent unintended dropping out of the battery, an

additional part working as a flexible holder is used in existing solutions.

A novel solution uses a soft part working as the sealing for the battery door. This soft part can be

designed in a way that it creates a little undercut for the battery (see Figures 1-3). Hence, the battery

cannot fall out unintended while opening the battery compartment without any additional parts.
