This study proposes an eco-innovative design and problem-solving process, which is based on TRIZ Su-Field analysis modeling. The Su-Field analysis model can assist designers to diagnose and solve most problems because it possesses an icon-and-symbol system and some transformation rules. The proposed process guides designers to construct a model of design problem through the Su-Field analysis modeling of object, then to rearrange and derive the new developed model by environmental concepts, and finally to obtain a new design prototype. Some design cases successfully demonstrate that the proposed process is conducive to elevate the efficiency of development of eco-innovative products.
