Design of Digital Moulded Bra Cup Based on Forward Engineering Method

Now, underwear industry has developed rapidly, moulded bra market share has become bigger quickly mainly because of its smooth appearance, crisp styling, better support for breast care effect. Surveys show, that the reverse engineering methods are used in the enterprise to get an ideal moulded cup by trying many times based on experience. It leads to long cycle of development and wastage of resources. This paper is based on the theory of Forward engineering used in designing the digital moulded bra cup shape, namely Modeling Software Constructing virtual 3D female breast datum system, forming a set of control curve with the technology of spline. Then inner and outer surface which can match the female breast shape was generated. Finally the digital moulded bra cup was formed. It has been demonstrated that based on the forward engineering methods the design of digital moulded bra cup can fully embody the human-oriented design concept greatly cut down the develop cycle, save time and resources.
