Example Project

A startup medical company based in Alberta, Umay™ Care imagined creating a device for digital eye strain, which afflicts a growing number of people as we spend prolonged periods of time looking at screens. We can use inline links. Knowing that applying heat to the eyes can help to loosen oil in blocked glands to relieve symptoms of Meibomian Gland Dysfunction (MGD) or dry eye, while cooling can reduce puffiness, Umay™ Care was looking for a way to integrate both therapies into an everyday routine.

Tangent took on the development of an alpha prototype, involving work across our teams of mechanical, electrical, firmware, and industrial design. We then put the prototype up against rigorous durability tests while thermal simulation software studied the temperature of a virtual eyeball, all making sure the device was performing as it was meant to. For months, a mannequin head used for testing wore the Umay Rest prototype and made its way around the Tangent office.

Our testing led to an overhaul of the device’s design into a portable single unit, which posed some challenges for the Tangent team. From a mechanical standpoint, managing the heat in such a small device that is entirely enclosed for ingress protection involved some creative problem solving.

Electrically, we reiterated the thermo-electric cooler power control circuit several times to get the best efficiency, and finding the perfect shape to fit different wearers’ orbital sockets also took some trial and error.
