为实现企业在短期内产生大量兼具风格继承性和造型创新性的设计方案,以应对产品造型日趋同质化及用户偏好日益多元化的现象,构建了一种在风格约束下的造型文法化推演模型。依据形状文法推演规则的内在机理,提出文法化逻辑演绎规则与物理约束准则相结合共同约束造型的推演过程,以提高造型衍生的科学性、准确性与高效性。该模型采用定量与定性分析相结合的方法提取典型造型,并用符号表征造型特征;经统计分析选取的初始形状,输入文法化推演机制;结合目标产品建立遴选规约,以精简初始方案规模。以新能源载货摩托车造型设计为例推演衍生方案,有效实现风格约束与创新设计的融合,提高产品造型设计开发效率,增强企业的持续创新力。
In order to achieve a large number of enterprises in the short term with both style inheritance and modeling innovative design, in response to the increasingly homogeneous product styling and user preferences increasingly diversified phenomenon, to build a stylistic grammar under the constraints of style Deduction model. According to the inherent mechanism of deducing the rules by shape grammar, this paper puts forward the process of deducing the deduction by combining the deductive rules of grammaticalization with the principles of physical restraints to improve the scientificalness, accuracy and efficiency of modeling derivation. The model uses the method of combining quantitative and qualitative analysis to extract the typical shape and symbolizes the shape features. The initial shape selected by the statistical analysis is input into the grammatical deduction mechanism. The selection criteria of the target product is established to simplify the initial scale. Taking the styling and design of new energy loading motorcycles as an example, the derivative derivation scheme is effectively implemented to achieve the integration of style restraint and innovative design, improve the efficiency of product design and development, and enhance the continuous innovation of enterprises.
