In the conceptual stage the function design process is realized by the computer aided application. After surveying on the function specification methods and the function modeling, a computer aided function design environment is analyzed. Subsequently based on a module library and principle catalogue, a solution finding process as a part of conceptual design is proposed for a creative design. In addition, a search algorithm to find the solution of adaptable function structure is also discussed. The concepts proposed in this paper can support the subsequent design stages, especially simulation for checking the function structure defects. 展开更多

They are efficient and appealing and are employed frequently for dome structures. Data generation for geodesic forms has always been a difficult task, from the days of hand data generation using tables of coefficients to today's specially written computer programs with many limitations and shortcomings. Formex algebra is a mathematical system which is ideally suited for data generation and configuration processing. The objective of the present paper is to introduce the concepts of formex algebra through which data generation for polyhedric and geodesic forms can be handled with ease and elegance. 展开更多

It not only gets the measurement of body, but also analyze the style of body shape. We have discussed the method of woman body fuzzy recognition in another paper and from that we divide woman bodies into thirty-six groups. In each group,bodies have one kind of basic block and there is difference between any two kinds. This paper puts forward thirty-six basic block modes based on various woman bodies. 展开更多
