Bakers Delight Reset Button

Designed & Built by Lachlan Mackie
Bakers Delight required the fabrication of a new mechanism to restart their point of sale (POS) terminals within their stores. The POS terminals comprise of a tablet housed within a metal case, periodically the terminals need to be reset manually. This had to be done by opening up the case and pressing the reset button on the tablet. Unfortunately this manual handling of the tablet would cause breakages between connecting wires and the tablet. To limit breakages and increase ease of use for the operator it was decided that a mechanical push button set in to the case housing was needed to assist in resetting the POS terminals.

In the original design of the terminal case there was an access hole that was intended to be used to press the reset button on the tablet. This hole was found to be unsuitable for direct manipulation of the reset button, the offset was too far away from the tablet to be reached by a pen and direct access to the button was blocked by a mounting bracket for the tablet.

This presented some design challenges such as how to have a button that operated sufficiently well whilst being easy enough for a retail worker to install. How to design a button that would operate around the mounting bracket for the tablet whilst being small enough for the case, and how to secure the button

To tackle these challenges first a CAD model of the metal case and tablet were constructed from measurements taken of terminals from the field. These models were used to inform and test prototype buttons before they were rapid prototyped using 3D Printing. From this process a design was settled on by Bakers Delight and the button was manufactured using injection molding.

Currently the reset button is installed in over 700 Bakers Delight stores in Australia and New Zealand.
