Jumping out of the original framework, this design seeks a vibrant shape, mainly using organic forms to make different levels grow from the basic shape, so as to achieve a breakthrough in the original shape. The functional area of the equipment grows from the back end, breaking the basic framework of the equipment box. The modeling technique of front and back can add its level to the overall sense of the equipment. The modeling includes many other different interpenetrating relationships, all for cutting the original block modeling. The lower part of the front panel is overhead, which visually weakens the bulkiness of the trolley. The first part is divided by different arc shapes to shorten the area without modeling and enrich the overall details. The armrest on the back naturally cocks up in accordance with the shape and jumps out of the overall shape. It can be grasped with one hand and pushed by the other hand. The shape at the handrail is too downward to occupy too much space.
