The Problem
“Todays children are spending half the time playing outside than their parents did”
(Scott et al. 2022)
Product Overview
Audio production toy that allows children to use plant surface temperatures to create, edit, modulate, and share their melodies
Mechanical assembly made with off the shelf components, custom PCB's, and custom mounting to prove viability & generate interest.
Top shell is shown, highlighting the bosses for bottom mounted screws, ribs for proper injection molding and component support, and cutaways for the screen, sliders, buttons, and speaker, all with proper drafts.

To prevent ingress, the product was designed with a gasket that fits between the top and bottom shell. As seen in the picture ot the right, the outside wall acts as the exterior retaining feature, keeping the gasket in compression.
As seen on the left, the interior support ribs keep the gasket in compression from the inside, along with the top and bottom shells. Other interesting notes include the thicker bottom bosses (where the screw is mounted into the bottom shell) to account for the greater stresses and support ribs (as opposed to a flat plate) for the battery.

Tolerance analysis was carried out for the following gaps: battery and bottom shell, battery bracket and PCB, PCB and breakout board, slider PCB pin slot, and finally, the top and bottom shell. The tolerance loop for the PCB and breakout board is shown in the picture.
