Innovative method for creating fitted brassiere wire prototype based on transformation matrix algorithm

It has been difficult to obtain the fitted bra wire shape for women’s breasts, since the under breast root shape extracted from 3D bodyscan breast images is three dimensional. A detailed matrix algorithm for the geometric relation is firstly introduced and presented for transferring the 3D bra wire shape to one that is 2D to create a fitted bra underwire shape prototype. In this paper, the under breast root shape was extracted from a medium average avatar, then the curve line was exported as a point format. Points were taken as research subject, then the transformation matrix algorithm was applied to the spatial coordinates of the points to fulfill the transformation. Thereby a detailed program was operated in MATLAB for obtaining the coordinates of points to create the contour for the 2D wire shape. The matrix algorithm method was a useful, simple and straightforward method to implement. In addition, it works well for various kinds of breast shapes.

Parametric design and process parameter optimization for bra cup molding via response surface methodology

Seamless and traceless undergarments have rendered foam sheet molding as an important manufacturing technique for the intimate apparel industry. Seamless bra cups are made by one-step forming technology. The three-dimensional (3D) cup shape is formed by using high temperatures and pressures with flexible polyurethane foams. Nevertheless, the mold head design process and control of the bra cup molding process are highly complicated and error prone. There is limited knowledge about the effects of foam properties, molding parameters and foam cup geometric parameters on molding process optimization. This research presents a response surface methodology as the approach for parametric design and process parameter optimization of bra cup molding. The proposed approach integrates 3D scanning via reverse engineering, parameterized-based remeshing and registration algorithm, non-linear mathematical prediction models for cup shape conformity, a model of foam shrinkage and example-based bra cup design and grading to optimize the bra cup development and production process. The experimental results show that this method is highly effective and more timesaving in the design and development of new products, as well as providing consistent quality control of the bra cup molding process.     

Baroque Exuberance: Frivolity or Disquiet

Robert Harbison defines the Baroque in the 17th and early 18th centuries, which is so often characterised in contrast with the Renaissance by its excess and drama. In doing so, he challenges the reader to consider whether this artful style of subversion, tension, movement, gravity-defying feats and freedom was really one of whimsical frivolity or subversive disquiet.
