  • the case of the suitcase can be obtained by molding plastics or by connecting flat parts, as well as by combining these methods.
  • the choice of the method of obtaining the case and materials affects not only the technology of the product, but also the modeling and design of the product.
  • the range of luggage is expanded by creating luggage for various functional purposes — for short trips, business trips, light luggage, luggage on wheels, etc.

  • the suitcase contains a handle configured to allow the case to be hung when it is in a collapsible configuration.
  • the product area is the sum of the areas of the two sides (front cover and base), thus the folded product, decreasing in overall dimensions in one plane, it increases in another.
  • the reduction of dimensions in the plane of folding is not so great, due to the fact that the product contains a supporting frame structure, which also takes up some volume.
