Lemberg's hardware engineering team was challenged with strict ("on the edge") design requirements for the device casing. The project required incorporating a round display with a specific communication interface and custom UI implementation.
The Lemberg team delivered a finished prototype that was near 1:1 to the original sketches and could be used for further market research and a fundraising campaign. The client valued cooperation with a single team of hardware and software engineers, mobile developers and testers.
Initially, the client provided us with a product idea, industrial design sketch and mobile app UI/UX.
Unlike software projects, hardware development should be executed in a specific order; mistakes during the initial phases are quite expensive to fix later on (or even not possible to fix).
We started with electrical components selection. Round displays seem to be easy and obvious; however, it was not easy to find a display of such size (3.4 inches) with an ultrathin bezel display and no square-frame around it.
At that point, we started two parallel streams of engineering: mechanical design and software development (firmware, mobile app).
During the mechanical design phase, product design was slightly adjusted to fit the electrical components and prepare the device case for 3D printing. Several design iterations were required to get to the point where all components fit the desired internal space.
Once printed, all plastic parts and electrical components were assembled to make sure they all fit and work as expected. All plastic parts were refined and painted to achieve the proper look and feel of the product and then reassembled. By that time, the mobile app and firmware were ready, and the prototype was tested as a whole.
