In product design, the selection of materials plays a vital role, and whether the material selection is reasonable or not will affect the artistic style of products and people's feelings about products. Excellent product design is inseparable from beautiful materials. Different materials contain different emotions and tell different stories to people.

Usually, the toothbrush handle is mostly made of plastic, but 1 this product is not all made of plastic, and rubber will be designed at the part where the toothbrush handle is held, because rubber is an elastic, wear-resistant, cold-resistant and aging-resistant polymer material, which can play a role in anti-slip and aging, especially when the hands are covered with water, the toothbrush made of plastic will slip from the hands because of the smoothness of the water, causing certain troubles to people; The toothbrush with rubber will be firmly held in your hand to ensure the safety and comfort during use.

Third, from the perspective of color.

Any design is inseparable from color, and different colors give people different feelings; Different TINT will form different beautiful pictures, which will have an impact on people's psychology. As brummer, a contemporary American visual art psychologist, said: "Color evokes all kinds of emotions, expresses feelings, and even affects our normal physiological feelings." Therefore, color is endowed with emotional factors. At the same time, the emotional effect of color is also related to people's experience and association, which has certain symbolic significance in a certain cultural environment.

Fourthly, from the point of view of modeling.
