Non intentional design



Non intentional Design is a book by U. Brandes and M. Erlhoff that deals with a phenomenon observable in our daily life. It deals with the creative re-appropriations of objects from the end user, in order to serve new and unforeseen functions. In the cover of the book (here shown) we can witness two Non intentional uses: the lipstick becomes a marker and the mirror a board. Often, it implies a change in the function and not a change in the features of the objects, normally defined as Product Hacking.


By observing such creative uses the designer can always learn how re-appropriations of his/her own design can occur thanks to the creativity of the user.


"Non Intentional Design describes the everyday redesign of designed objects by the user. It does not create a new design, but through use, creates something new or replaces the old." Uta Brandes
