设计 (design) is the process of creating a plan or blueprint for a product, system, or structure. It involves understanding the needs of users and finding solutions that are both functional and aesthetically pleasing. Designers often work in various fields, including graphic design, industrial design, and interior design, to develop innovative ideas that improve everyday life. The design process typically includes research, brainstorming, prototyping, and testing. Tools such as CAD software and sketching are commonly used to visualize concepts. Effective design not only enhances usability but also communicates a message, making it an essential aspect of art and engineering.
