1) Safety first principle.
The product is ultimately used by users, so the material selection should ensure its safety in the process of production and use and ensure protect human health and physical and property safety from injury or loss. Designers should first understand the needs of material selection through the analysis of the physiological and psychological characteristics of the target population pay attention to safety factors. Then study the basic properties of relevant materials, especially pay attention to some special situations (low temperature, high temperature, humidity, etc.)
Whether the materials in the will produce substances that are not conducive to safety. For example, children are a special vulnerable group. They are immature in physical and mental development and lack self-confidence. I am aware of safety protection. Therefore, in the design of children’s products, we should try to avoid colorful surface painting and the use of heavy metal materials, because the spraying is too dangerous.
They generally contain lead, and heavy metals may contain arsenic, cadmium, etc. children are prone to poisoning or disease after long-term exposure.
2) Practical and aesthetic harmony.
Realizing the practical function of products is the value of product design, and meeting people’s psychological and aesthetic needs is also excellent product design should have. When selecting materials, we should grasp the relationship between practicality and aesthetics, and make rational use of materials while ensuring practical functions.
Its own surface characteristics, namely texture, color, luster, mechanism and other characteristics, to create the artistic beauty of the product and strive to make the product practical and aesthetic harmony and unity. Stainless steel pot is a successful case. On the one hand, stainless steel has good thermal conductivity, heat resistance, and corrosion resistance. It can transfer heat energy well, achieve the purpose of cooking food and complete the practical function of the pot. At the same time, using the ductility of stainless steel to make a beautiful curve
The pot body with thread makes the shape of the pot more compatible with people and the environment. The color and luster of stainless steel metal highlight the cleanliness of the product. After metal drawing treatment
The surface texture can also increase the modernity and fashion of the pot.
3) High quality, high efficiency and low cost.
Designers are between consumers and producers. On the one hand, they should ensure the function and quality of products, on the other hand, they should, for the consideration of enterprises, control costs and obtain benefits. Therefore, designers should fully understand and analyze the technical factors of materials and the situation of relevant enterprises, and select materials.
To ensure that the material forming process, processing technology, surface treatment and other technical factors adapt to the enterprise’s processing equipment and production technology. In addition, in ensuring excellent on the premise of quality, try to select materials with low technical difficulty and short production time to reduce the cost. At the same time, it is also necessary to analyze the economic factors of materials and give priority to them.
Use materials with rich resources, low price, and low transportation and recycling costs.
4) Environmental protection principle.
Facing the deteriorating living environment, protecting the environment has become everyone’s obligation. Material selection in product design.
It can be carried out from two aspects: saving utilization and reducing pollution. By analyzing and simplifying the types of materials, avoid the use of redundant materials and facilitate the production of products and recycling. Products made directly from raw materials without coating on the surface can also achieve the purpose of easy recycling. Select degradable and recyclable the materials used not only reduce environmental pollution but also save resources.
5) Comply with national policies and regulations.
Whether the products can pass the review and obtain the qualification for circulation in the society depends on whether the products comply with national policies and regulations.
Yes. This requires designers to master the relevant policies and regulations of the designed products, and select materials based on this information.
6) In line with social and cultural characteristics.
Human beings have been influenced by local social culture for a long time, and have common use of bamboo for various materials furniture. People will feel uncomfortable when they give him wooden or metal furniture. Because of this, the same kind of products are in different environments, different regions, and different markets.
There will be some differences in the application of materials in different nationalities. Before product design and material selection, the social environment of the target population shall be evaluated research, as far as possible to select materials in line with the social culture of the target population, so as to facilitate people’s use and be more easily accepted.
In short, the selection of materials in product design requires the designer to comprehensively analyze various influencing factors and select materials through the above principles and methods selection, so that the materials can “make the best use of everything” and make the product design achieve a more satisfactory effect
