Abstract
This paper presents the design and validation of a portable coffee-making device tailored to the needs of urban drivers, developed as part of an undergraduate project-based engineering course. The project originated from a real-world problem identified by students: the lack of practical, affordable, and high-quality solutions for consuming freshly brewed coffee during urban commutes. A comprehensive design methodology was employed, encompassing market research, user surveys, thermal and energy analyses, as well as CAD modeling and prototyping. Multiple alternatives were evaluated through a multicriteria decision-making framework using the Analytic Hierarchy Process (AHP). The final concept integrates a stainless-steel body, a fenda-type lid, and a 12V vehicle-powered heating system. The prototype underwent simulations and calculations addressing thermal retention, heating performance, structural stability, and material compatibility. Results indicate that the solution meets key performance and usability criteria, including preparation time, user safety, and manufacturing cost. This study demonstrates the pedagogical effectiveness of using project-based learning to develop not only technical competencies but also critical thinking and innovation in engineering education.
