The paper aims to separate the radical innovative design from the radical innovation and innovative design as an independent design method for thematic analysis. The basic method for study is interdisciplinary literature search both in technological innovation management and design. The first, three topics is divided from the studies of the technological innovation management. Then, the analysis is carried out for the studies of the design, engineering design and innovative design. The innovative design is divided into three types and the radical innovative design is one of them. The opportunities, key implement methods for radical technologies and process models for radical innovative design is analyzed. Some conclusions are drawn from the literature analysis. The first is that the three features of radical innovations given by Leifer can be the key features for radical innovative designs. The second, the radical innovative design is a kind of innovative design in which interdisciplinary knowledge and technologies are searched and applied. The topics for the radical innovative design are opportunity identification, radical technology implementation and design process model development. Under C-TRIZ framework a few design models for radical innovation have been developed. The last, the both studies in the technological innovation management and the design for radical innovation can be reference each other. This view is a new thinking for interdisciplinary study of innovative designs.
