suitcase / Suitcase Travel

This suitcase can not only slide standing like a common case, but also be pulled lying down on caterpillar tracks. Users can switch freely between the two methods by turning the trolley. The caterpillar tracks, covering 40% of the surface, guarantee the fluency and convenience for using. Meanwhile, users can open the case as normal since the tracks can be broken.
The purpose of this design is to help users cope more easily with some special road situations, for instance, going upstairs or downstairs, or walking on a slope, etc. Users can even put some light goods on the case.
