• Resumen

  • The authors have developed a method/computer tool to assist (student) engineering designers in generating concept designs. The method is based on the chaining of physical laws and complementary basic schemata (BS). The tool generates chains which serve as an aid in the development of concept designs. In this paper, the authors compare concept designs generated by a control group (which used functional structure and morphological matrix) with those from an experimental group that used computer-generated chains. The experimental group was found to have generated a greater number of different solutions than the control group; the generation of different solutions indicates a high level of variety and a better chance to find potentially innovative solutions. The established difference in the number of different solutions is statistically significant and the results indicate that the BS facilitate greater variety of concept designs.
