Abstract
Designer's drawings could be important clue for understanding the creative thinking process.We prepared experiments to see how drawings devote to creative design.Subjects were assigned tasks to design paperweights by two different keywords. From observation of drawing process, two different thinking types were found : one was who searched as possible as many associations from the given key words, then select one from them.The other was who drew abstracted forms and gradually brush up them to get most fitting image for given key words.Then, the sketches were evaluated and analyzed the relations of the thinking types and their drawing ways.The former type sketches were made by caricaturized and single line drawings, and the latter type sketches were made by elaborated and repeated line drawings. Most of good results were seen in the latter type group. From the results, we became to think that the creative design can be got only when the keyword was once lifted up to high abstracted level concept, which could be fixed after frequent interactions between the concept in mind and drawn images.
