基于权重化特征与形状文法的产品识别设计
|
摘要
为提升企业产品形象、提高产品识别度,提出基于权重化特征与形状文法的产品识别设计流程。首先运用多元统计方法萃取符合企业风格意象的关键词汇,然后对企业代表性产品进行形态分析得到外形部件和其对应的造型特征,建立产品造型特征与企业风格意象的映射模型。以方太抽油烟机为例,计算了外形部件在企业风格意象中所占权重和各造型特征的贡献率,随后对外形部件要素执行造型文法的修改规则,对修改结果评估后发现,对于权重高、贡献率大的部件特征要减少修改,对于权重低、贡献率小的部件可进行适度修改,使产品设计具有一定变化并符合企业风格意象。该设计流程可用于企业产品设计管理,指导企业产品识别设计。
In order to improve enterprise products image and increase products identification, a product design process is put forward based on the weight of the features and shape grammar. Using multivariate statistics method it extracts the key words and conforms to the enterprise style image. Based on the morphological analysis of the enterprise representative products, it obtains the shape of components and their corresponding modeling features appearance, builds the product modeling features and enterprise style image mapping model. Taking "Fang Tai" range hood as an example, it calculates the shape parts style and image in the enterprise of the weighting of the contribution of each form features, executes the modify rules of shape grammar to the shape component elements. The results show that the high weight and high contribution rates for components feature reduce the change, but the small contribution rate and low weight components may be appropriately modified to make product design changes and comply with certain corporate style images. This design process can be applied to enterprise product design management, corporate product identity design guide.
