What can a remarkable community of 6,000 retired academics living on the campus of Tsinghua University, Beijing, tell us about strategies for ‘ageing well’ in societies around the world? The Ingenuity of Ageing tells the story of an experimental piece of design research carried out by Dr Yanki Lee, a research fellow in the Helen Hamlyn Centre for Design at the Royal College of Art, who spent a year in China investigating new approaches to design for ageing. Supported by a UK-China Fellowship of Excellence funded by the Department of Business, Innovation and Skills (BIS), Dr Yanki Lee’s post-Doctoral study combines the techniques of reflexive ethnography and action research in order to challenge conventional thinking about the designer as expert and propose an alternative, participatory model of social interaction and innovation through which the ingenuity of older people can be revealed.
