The appearance design and packaging design of the product are very important. Packaging design endows the product with unique personality, establishes a perfect visual image for the product, and enhances the intrinsic value of the product; the appearance design is not simply considering the shape of the appearance, but also needs to be innovated and researched from the aspects of pattern, color, material, man-machine, etc. The shape has novel and unique characteristics, conforms to the public's preference, and is simple and atmospheric. In the process of appearance design, designers need to go through sufficient market research, roughly classify the advantages and disadvantages of existing similar products, find the direction people like, draw sketches according to the direction of investigation, and determine the design ideas and directions. Better positioning the product appearance design accurately, and then modeling, rendering, and P-diagram. In the appearance design, the choice of materials will directly affect the shape of the product. The materials are different and the workmanship is different. Some materials cannot afford excessive bending and polishing. If the material selection of the product is incorrect, there is no way to perfect the shape and cannot achieve the expected effect. Product appearance design needs to pay attention to stability. Designers usually reduce the physical center and visual center of the product by enlarging, widening and weighting the chassis, so as to make the product more stable and reliable. Designers need to have innovative and rich imagination, have their own innovative design ideas, and cannot be imprisoned by existing products, but they are not imagined out of thin air. They need to be based on scientific and reasonable forms, materials, structures, Innovations and improvements in human-machine and other aspects make the product give people a unique and novel feeling, and it is easier and more convenient to use. Product appearance design needs to be feasible and grounded. Art is integrated into the industrial products that can be produced through various processes to ensure that the designed products can be produced and manufactured, which is the real product design. No matter how perfect the design is, if there is no way to complete the landing production without reality, it is just a meaningless fantasy and has no value.
