Consumers' different aesthetic experience affects their choice of products, so how to construct product design features space based on consumers' aesthetic experience, especially how to integrate traditional cultural elements into modern product design, has become one of the most effective ways to improve product design quality.Taking the innovative design of traditional Chinese Miao's patterns on canvas bags as an example, this paper constructs the mapping relationship between consumers' aesthetic experience and product feature space on the basis of analyzing the feature elements of Chinese Miao traditional patterns "Jiuqu River flower", as pronounced in Chinese.Using word cloud semantic tool, this paper analyzes the interview results of three consumer groups, namely, fashion youth, intellectuals and housewives, and obtains the aesthetic expression of three consumer groups on the innovative design of traditional patterns on canvas bags. Based on this, the feature elements of traditional pattern extraction and redesign of "Jiuqujiang River Flower" are used. Three canvas bag styles containing traditional cultural elements were constructed for different perceptual word pairs. Finally, the 7-level semantic difference quantization method of Kansei Engineering was used to quantitatively evaluate the effectiveness of the spatial mapping method of aesthetic experience and product features. The final results showed that the modern product quality of creative design can be effectively improved by integrating with the traditional Chinese cultural elements, on the basis of making the mapping from aesthetic experience to product feature space, so that to meet the consumers' aesthetic needs to the most.
