The product shape is fused by 2-3 large geometric shapes, such as cylinders, cones, etc. The transition between geometric bodies is directly stacked, the turning surface is rounded and transitioned, the rounded corners on all ridges and the curved surface on the plane are small, and the base adopts soft materials on the basis of meeting the load-bearing requirements to protect the fuselage and the ground. At the same time, it creates a certain "breathable" space, which is light and elastic.
