The assignment asks for a discussion on four popular smart suitcases, focusing on their external appearance. The file contains detailed requirements and specific expectations.
Additionally, we need to cover the design language, product size and functions, materials, and textures of the smart suitcases. Each of these aspects will be divided into four parts, making a total of four parts for each category.
To meet these requirements, we are expected to gather examples of real bags and provide analysis and discussions based on them.
