Keurig K-Duo — Product Vision Through Research

Integrate two brewing systems into a single, cohesive form. Balance countertop footprint, usability, and manufacturability. Create a design that feels approachable, premium, and intuitive.

The brewer also had to support multiple user scenarios — single cup, carafe brewing, quick weekday use, and social occasions.

Market and customer research established a product opportunity matrix across thermal and glass carafe segments. Concept exploration and sketching then moved into form development and CAD.

Opening-mechanism concepts were evaluated for usability, workflow efficiency, and alignment with the overall component architecture. Lightweight volumetric prototypes — machined high-density foam, finished with real coffee vessels — put the proportions on a real counter early.

The final design demonstrated how a dual-brewing system could feel simple, modern, and approachable rather than complex or oversized, translating brand values and user needs into a production-ready consumer appliance that balances aesthetics, engineering constraints, and real-world use.
