In this paper the history of a particular type of product design is analyzed, compared and structured. The analyzed products are all of the type where existing objects are used or even incorporated into the design. This principle is known in the art world as the ready-made. In this research transformational- and composed ready-mades and several variations are described. The design principle of using existing objects in designs is then compared with the relation between novelty and typicality as predictors of aesthetic preference, as researched by Hekkert et al. From there it is argued that the ready- made principle could possibly contribute to designing pleasurable products because the resulting objects incorporate both novelty and typicality in their presence.
