Smart Speaker Design
2021-2021
The Smart Speaker Design showcased here was my work done during my time in the Google Hardware Product Sprint program which is a selective 12 week program led by Google. The design is made for injection molding taking into account DFM/DFA, tolerances, and fastener solutions, as well as other factors. The program was great because it was not hands on guidance but rather allowed me to completely work and design my product on my own.​
​
The main focus below is my design iterations for the smart speaker model.
Product Description
The smart speaker is designed to be a stand for Funko Pop action figures. The idea behind the design is that it would be minimalistic and have a supporting factor so that users can display their collectibles on top of the speaker and eventually there would be an interactive software that allows the collectible to connect to the speaker.
