innovative suitcase design with hanger system and vertical expansion

"Create a concept image of a suitcase with an innovative design featuring: A built-in hanger system at the top for neatly organizing clothes. Foldable tray storage inside the suitcase, allowing users to sort items like shirts, pants, and undergarments. A vertical expansion mechanism: when the handle is pulled, the suitcase extends upward into a two-story structure. This should show panels rising from the internal compartments, creating a compact wardrobe with a sleek, modern aesthetic. Highlight the transformation process, focusing on the handle being pulled and the suitcase expanding into a wardrobe-like shape. Include details like smooth materials, metallic accents, and a person interacting with the suitcase."
