The process of making the transformer model was not very smooth at the beginning. It needs to be strong so that people can read and rest on it. It needs to be powerful, with blueprints, coffee cups, handouts, and umbrellas. It needs to be light and convenient for people to carry around.

The first prototype is just a simple framework, so it can be split and put in the package. However, in order to make it easy for people to split and assemble, the nodes are not very stable. At the same time, it fails to meet more needs and functions of users.

The second prototype added a lot of details and functions and added layers to divide the storage space of different sizes. A small space can be used to store manuals and stationery, a larger space can be used to store books and sundries, and a separate storage board can be used to store coffee or mineral water bottles.

The third prototype is optimized and improved again for portability. The set handle is convenient for people to move and carry at any time. At the same time, the handle can be hung with a rope, similar to the shoulder strap of a schoolbag, so it is very convenient for people to carry and travel.
