"Da Dai Li Ji · Zeng Zi Tian Yuan" records: "The way of heaven is called round, the tunnel is called square, the square is called secluded and round is called Ming." The philosophy of Tianyuan is well known to every Chinese, and the "cubism" design method of cutting or combining geometric forms has a history of one hundred years since it was advocated in the "Bauhaus" period; it has gradually become the mainstream of design. Geometry makes the product shape more unique. In line with the aesthetic of the present design. My design is a group of small household appliances placed on the desktop, consisting of night lights, fans, humidifiers and speakers. The design is inspired by the geometric element of "circle". The basic shapes of sphere, hemisphere and cylinder are used to create new forms. In terms of materials, simple wood materials are matched with plastic materials with good plasticity, thus forming a seamless turning point and plug-in: in the selection of materials, metal materials and plastics can also be selected, taking into account the original natural beauty and the simplicity and fashion style of modern flavor. Give full play to the characteristics of metal, wood and plastic materials. Color matching "crescent white", "girl powder", "mint green" and "sky blue" are all good choices for young people.
