By researching reading behaviors and reading situations, we can then apply appropriate product functions and product semantics to meet the user's needs.

1. The first mock-up model resulted in lines formed by the structure when scrolled.
2. The second mock-up involved testing materials on the surface and adding more pieces to the structure to reduce creases when rolling the paper. However, some creases remained.
3. The third model reduced the width of each piece. Although the paper rolling process almost resembled a circle, there were still some minor creases.

Based on the results of the previous tests, I redesigned the inside structure as a spiral with a smooth surface for attaching the paper. The outcome demonstrates that it no longer creates creases.

The spacing between each piece can control the scroll's diameter, and we've also added a central structure to secure the paper clip and prevent paper from loosening during rolling.

”簡牘” ( jiǎndú - bamboo and wooden slips)” were the main media for documents in China before the widespread introduction of paper during the first two centuries AD. The long, narrow strips of wood or bamboo typically carry a single column of brush-written text each, with space for several tens of visually complex ancient Chinese characters. For longer texts, many slips may be bound together in sequence with thread (Book).
