Combinatorial modeling design method Combinatorial modeling design method mainly includes shape combination and function combination method. It can also be divided into plane combination method and vertical combination method. Plane combination method-the outer packaging box consists of two parts, the outermost room is a beautifully designed paper box, and the inner layer consists of four independent fan-shaped iron boxes. The four sectors are skillfully combined into an organic whole through the design of patterns. Each sector contains a moon cake with different tastes, which makes the moon cake box not only have the artistic conception of enjoying the moon, but also have the characteristics of convenient carrying and use, and is suitable for four moon cake boxes. In addition, the outer packaging box is also composed of two parts, the outermost layer is a beautifully designed iron box or paper box, and the inner layer is composed of seven small sectors and a larger round can, which are integrated through structural design and pattern design. A big moon cake is placed in the round jar, and a small moon cake is placed in each small fan-shaped iron box, which symbolizes the whole family enjoying the moon and respecting the elderly. Vertical combination method-the tank body consists of four independent circular iron cans, and the bottom of each cylindrical small can is convex and rolls with the tank body. The tank body and the bottom of the lowest cylindrical small tank are mutually rolled, and the tank cover adopts a double-layer structure, and the inner layer and the outer layer are formed inside. In this way, after four small cylindrical cans are nested with the lid, an antique cake box with flat appearance is formed, and five parts are connected together with a gold thread. This structure is novel in shape and has secondary utilization. On the other hand, the box is composed of two semi-cylindrical shapes. Moreover, it is designed as a bamboo tube, and the inner layer consists of four independent small round cans. According to the size of the small round can, it can be formed by stamping, or the can body and the can bottom can be rolled inside, and the can mouth can be rolled inside. The small round tank at the top is connected with the inner roller of the tank, and is equipped with a green hand rope, which is seamless. This structure is easy to open, has strong visibility and display, and also has good secondary use performance. The symbolic design of Mid-Autumn moon cakes is not so much a traditional food as a kind of culture, a kind of sustenance to communicate feelings, kindness and friendship, bearing the blessings and expectations of ordinary people from generation to generation. Therefore, the design of mooncake boxes should reflect a culture, such as making mooncake boxes into double hearts or putting four mooncakes in the middle to express love directly, which can be used as holiday gifts for elders and elders far away from home. It echoes China's traditional virtue of "I am old and I am young". Another example is to make the moon cake box into a thick book shape. One end of the tank body is connected with a semicircle block, and the right angle is excessive. The mouth of the tank is rolled inward, and the tank cover is hinged with the semi-circular block. The tank cover adopts double-layer structure, and the inner layer is convex and rolled together with the outer layer. Both the tank cover and the tank bottom extend out of the tank, and like the tank, the four corners are right angles. You can attach some information about moon cake culture to infiltrate the moon cake culture into the atmosphere of enjoying the moon and giving gifts in the Mid-Autumn Festival. At the same time, this pot shape has good secondary utilization and can be used as a pencil case. There are also round iron boxes, which are safe all the year round. The bottom of the tank body is connected with the inner roll of the tank body, and the mouth of the tank body is rolled. When the tank cover is a single layer, the tank body is ribbed or neck-shaped; When the tank cover is a double-layer structure, the tank mouth is slightly flat, the inner layer of the double-layer cover is raised and connected with the outer layer, and the outer edge of the inner layer is punched with several bumps for positioning. The double-lid can has smooth appearance and beautiful and novel shape. At the same time, the overall shape is like ancient copper coins, which means that financial resources are rolling. This can can be combined with a paper box, with the iron box as the inner box, tea and other gifts placed in the central square hole and the paper box as the outer box. Spend a full moon and enjoy the moon under it. "Moon" is one of the central topics of Mid-Autumn Festival. The creative design around the "moon" has a wide range. For example, there is a stepped cover type tank. The tank body and bottom are the same as ordinary cans, but the lid has been creatively improved, which is multi-layered and stepped, showing the moon with windows, with both form and spirit. There are many kinds of packaging materials for moon cakes, such as paper, wood and plastic. All kinds of materials have their own characteristics. As a high-grade gift tin box packaging, it is feasible to absorb the strengths of many experts and improve the printing and processing characteristics of iron sheets. In the past, iron boxes were all round, while cartons were generally folded at right angles. The bottom of cans and cans were made of the same piece of iron, and cans were formed by folding technology. In this way, the four corners of the tank are right angles, the tank mouth is rolled in, and the four corners of the tank cover are also right angles. The mouth of the lid is folded inward and pressed tightly, so that the shape and processing characteristics of the carton are integrated. The shape of a can is like a paper box, which changes the traditional image of an iron box and gives people a refreshing feeling. Another example is a hexagonal deep-cover nested tank. The corner of the tank body adopts a small arc transition, and the tank bottom is rolled with the tank body after being extended. The tank cover is also divided into two parts, and the forming process of the cover body and the tank body is the same. The outer edge of the top cover is pulled to the same height as the inner edge of the cover body. After the cover body and the cover top are rolled up, the cover top is flush with the upper edge of the cover body. The top surface of the lid is flat, and the height of the can purlin is the same as that of the lid body. This kind of tin box combines the appearance characteristics of plastic cake packaging box, with elegant color patterns, giving people a luxurious feeling, and is suitable for making seven-star moon cake boxes. Multifunctional design method Ordinary mooncake tin boxes are discarded after use. While fully ensuring the packaging performance of mooncakes, designing multifunctional tin boxes is an important way to expand the market of mooncake tin boxes. For example, an iron box is shaped like a candy box and consists of six semicircular petals. The bottom of the tank is rolled in and the mouth of the tank is rolled in. The can cover is formed by stamping, and the can cover is slightly convex or stepped. This can shape is suitable for making seven-star moon cans, and consumers can use it as a candy box after use. Another example is the hand-pushed moon cake jar for children, which is rectangular in shape. The outer edge of the tank bottom is concave relative to the outer surface, and the depth of the concave is the same as the height of the curling. After the tank bottom and the tank body are rolled up, the outside of the tank bottom is flat and the tank mouth of the tank body is rolled out. The structure of the tank cover is complex, and the edge of the tank cover is rolled in. Cut off one end of the cover, fold it back and press it, and make a transition with the arc of the cover. Several positioning points are punched out on the cover surface, and the hand push function is realized after the cover is closed. The structure is simple and novel, and it can be used as a pencil case after use, which accords with children's purchasing psychology. Another example is the moon cake bucket, which has no special structure, but can be used to hold tea or other food, which is in line with the housewife's purchasing psychology. Copying design method Copying design is mainly used for the independent packaging of a single moon cake. Some symbolic shapes are selected as models, and the shape design is carried out according to the printing characteristics of iron sheets. This method has a wide range of applications, and many can shapes can be designed, which is deeply loved by consumers. For example, scallop-shaped cans give people a novel and high-grade feeling, and the upper and lower pieces are connected by hinges, which is convenient to open and carry, and is suitable for children's consumer groups. The jar has obvious meaning, and with corresponding patterns, it is suitable for young people to convey their feelings. It can also be used to hold small ornaments after the Mid-Autumn Festival.
