Multiobjective factors of product modeling design.

Factor	Content
Brand	Brand characteristics and brand gene are the first factors that must be considered and satisfied in product modeling design. A brand’s image and connotation will drive the style of product modeling design. The designer’s main responsibility is to convey the product’s brand connotations and culture through product modeling design so as to accurately and consistently stimulate user cognition
Function	The function is the core service provided by the product itself, which will determine the direction and orientation of product modeling design to a certain extent. The orientation of the product function has an important impact on product modeling design
Business	Product modeling design will eventually reach consumers through commercial marketing, where the ultimate purpose of production is sales for profit. Product business positioning has a significant influence on product modeling design and is also an important constraint factor
Technology	Different processing requirements, materials, and production processes will directly affect the final shape of the product modeling design
Material	The use of different materials involves factors, such as product brand positioning, function consideration, and commercial marketing, and the properties of the materials themselves directly affect the final shape of the product design
Human-machine	Product modeling design ultimately serves humans. Thus, the form, function, usage, and scenario of the product must be compatible with human posture and conform to the fixed range of values and movement of the human body. The stability, safety, comfort, and other human-machine factors of the final use of a product are also important constraints of product modeling design
Others	In the face of sustainable development, product design also needs to consider factors such as environmental protection and life cycle. Changing social, cultural, and fashion trends and consumption habits are also important constraint factors
