一.引言产品设计要解决产品的功能、造型和技术条件,这是三个基本要素。造型是产品的实体形态,是功能表现的形式。无论是什么形态都有其共同的造型要素,由这些造型所构成的形态分为有机形态和几何形态,产品的形态呈属几何形态的造型,由多种元素作为造型单元组织成新的形象,通过掌握这种方法来掌握形与形、形与色、形与体、形与空间等关系的构成规律。创造出一个完整的形象,是用多种形式规律展开造型,进而形成了一套符合产品造型设计的构成方法。于是可以分成各个单元来解决形体构成的问题,本文就其中的课题展开对构成方法的研究,以期获得与发现再创造的新造型单元和灵感群的机会。二.曲线结构的形态曲线在平面上的概念有波浪形、锯齿形、流线形和不规则形。由于功能的要求才决定了产品外形的曲线状态。人们对形的认识有一个漫长的历史过程。词源上对“形”的释意为形象、形体,“在天成像,在地成形。”形态是由造型的行为而产生的结果。形态又有两种,一为人为形态,二为自然形态,天造之物,地造之物,人造之物是后天形成的。用木叫 I. Introduction Product design to solve the product’s functionality, modeling and technical conditions, which are the three basic elements. Modeling is the physical form of the product, is the form of functional performance. No matter what form has its own common modeling elements, the shape formed by these shapes is divided into organic forms and geometric forms. The shapes of the products take on the shape of geometric shapes, which are organized into new images by various elements as modeling units, By mastering this method, we can grasp the rules of the relationship between form and form, form and color, form and body, form and space. To create a complete image, is to use a variety of forms of regular shape, and thus formed a set of product modeling design approach. So it can be divided into various units to solve the problem of body composition. In this paper, we will start the research on the constitution methods in order to obtain and discover the new modeling unit and inspiration group again. Two. The curve of the curve The concept of the curve in the plane wave, sawtooth, streamline and irregular shape. Due to the functional requirements of the shape of the product determines the curve of the state. People’s understanding of the shape has a long history. Etymology of the “shape” of the interpretation of the image, body, “image in the sky, the formation of.” Form is the result of modeling behavior. There are two other forms, one for the human form, the second is the natural form, the creature, the creature, the artifact is acquired. With wood called
