This issue of diid talks about design through narratives and illustrations of approaches, experiments, and projects. It proposes a mapping useful for re-reading the design complexity, exploring its boundaries, and tracing its evolutionary lines. The invention here represents the identification of a possible solution that the designer “discovers” within the available knowledge. In fact, the research of design “disrupts to reformulate” through the discussion of consolidated paradigms and schemes. The inclination to experimentation and the tendency to contamination thus makes it possible to define design as an inventor, a privileged place for the search for new behaviors, new material, and sensorial universes in the relationship between man and artifacts.
