一、 The innovation in product appearance research and development mainly manifests in the following three aspects.

1. Innovative features: Functionality is the foundation of a product, and innovative and practical features often attract the attention and interest of consumers the most.

2. Innovative appearance design: Innovative appearance design and color are essential factors that attract consumers and can affect their choices. Because color has a proactive and captivating infectious power, it can influence people's emotions and psychological changes before styling, thus achieving the goal of attracting consumer attention.

3. The unity of function and appearance: A product with good color matching can move people's hearts and attract attention. The combination of product functional design and appearance design can make the product stand out. Because the appearance design is meaningful only when it conforms to the product's function and structure, the rationality of the internal structure of the product must meet the needs of the product's appearance design, so that the perfect combination and unity of appearance and structure can ultimately stand out.

二、 Product appearance design refers to the combination of product shape, pattern, and color to create a new product design that is aesthetically pleasing and suitable for industrial applications. Product appearance design requires the use of factors such as materials, texture, color, and decoration.

1. Material appearance

By using corresponding production methods to produce physical products, in addition to shape design, product appearance design plays a significant role in the quality of materials. Here, material refers to the appearance of material texture.

Materials are closely related to aesthetic psychology. Aesthetics is a psychological activity, but all psychological activities are based on physiological foundations. The aesthetic psychology of materials first forms physiological sensations through sensory media such as visual, tactile, auditory, olfactory, and gustatory senses, and is constrained by the environment. The same material, at different distances, light, sound, color, temperature, humidity, and speed, people's physiological experiences are different, usually through the joint contact and association of two or more senses with material characteristics.

2. Appearance texture

Texture is a reflection of the surface quality of industrial products and a complex physiological and psychological process. Through psychological analysis of objective and specific physiological and psychological perception processes, the expression medium texture of industrial product appearance quality factors can be established.

Therefore, when designing surface textures for products, we need to consider the image management information such as different forms, colors, rhythms, and rhythms of the designed appearance, which can bring people a certain impression, create a beautiful emotion, and give people a visual sense.

3. Color design

Color design is very important for products. Color can earn customers the first recognition of the product in terms of color. So far, color has been rarely mentioned in research reports on product development as an overall engineering background that occupies a lot of space, and is often considered afterwards without strict inspection systems and standards.
