The use of prototypical product shapes allows to structure and support the intuitive aesthetic design process. Prototypicality, a cognitive variable, is the extent to which an object represents a category: it shapes our aesthetic feelings with products, affects usability, makes up the products' look, and affects products' aesthetic evaluations and preferences. A mental prototype is a category's central element. We all have artifacts' prototypical information, however, designers are not aware and do not use it explicitly. These concepts have seldom been applied in design. Consequently, we explored how to use prototypical shapes for the aesthetic design process. 1. We proposed vectorising and interpolating 32 hand drawn Pepper Mills, PMs, to get the prototypical shape. In 2, we found the most innovative, original and typical PMs (n=74, 20 PMs). 3. We then used rules to explore aesthetic design possibilities and to transfer attributes to the prototypical PM shape. PMs' aesthetics, usability, and design pedagogy issues are discussed. We suggest a structured simple way to design the product's aesthetic for non-expert designers and applicable to other aesthetic cognitive variables.
