By using the aesthetic gene network of product form, the paper aims to comprehensively analyze the correlation of exterior contour curve of desk lamp, and identify the key elements of product optimization or innovative design. The cubic Bezier curve is used to encode the exterior profile curve of the lamp, and the coordinates of the control points are adjusted regularly to generate a new curve shape. The visual perception of the curve is carried out to identify the correlation between the curves; Taking the curve gene as the node and the correlation as the edge, the aesthetic gene network of product form is constructed, the topology of the network is analyzed, and the key design knowledge is extracted to assist the designer in product design. Using the theory of product form gene network to find the key nodes of prototype design, the design is optimized to make the product modeling design more in line with the aesthetic habits and preferences of consumers. Through the case study of table lamp contour, it is proved that the product form gene network is practical and reliable in product detail optimization and innovative design, and can help designers find key design nodes and coordinate the design of the gene group.
