Design methodologies, usually versatile, often need tailoring for specific industries. Medical product design is one such field with distinct challenges. Whistle Design Group in Melbourne, Australia, adept in various industries, eyes MedTech as an expansion avenue. This project explores the medical industry and design processes in-depth, synthesising knowledge to curate a custom design methodology. It‚ tailored for Whistle but can serve broadly. The project‚ second phase applies this methodology by designing a phototherapy light system for neonatal jaundice, testing its practical utility and showcasing the research's value. The experience paves the way for Whistle's potential foray into MedTech or might even birth a new specialised entity in medical product design. This is the convergence of research and hands-on application, fostering innovation in the healthcare domain.
