DESIGN SUPPORT OF PAPER PATTERNS FOR TWO PIECE BRASSIERE CUP

Abstract

A method to design the two-dimensional shapes of patterns of two piece brassiere cup is proposed when its target three dimensional shape is given. A brassiere cup consists of several patterns and their shapes are designed by repeatedly making a paper cup model and checking its three-dimensional shape. For improvement of design efficiency of brassieres, such trial and error must be reduced. As a cup model for check is made of paper not cloth, it is assumed that the surface of the model is composed of several developable surfaces. When the two-dimensional shape of an edge of a paper pattern and the target three dimensional shape of the edge are given, the surface of the pattern is uniquely determined. Then, the pattern with two edges can be designed by optimizing both shapes of edges so that determined developable surfaces from individual target edge shapes coincide with each other. It was experimentally verified that the edges of a designed pattern using the proposed method formed the target shapes.
