[0002] In the current technological context, the design and manufacture of trolley cases integrate material science, engineering design and human considerations to meet the modern traveler's needs for convenience, durability and versatility. These cases generally use high-strength materials such as polycarbonate, acrylonitrile-butadiene-styrene copolymer and aluminum-magnesium alloy to ensure that the case is both light and strong. The internal structure often uses a honeycomb design to enhance rigidity and reduce weight, while the exterior may be covered with an anti-scratch and waterproof coating. With the development of smart technology, some high-end trolley cases also integrate GPS tracking, smart locks and charging functions to further enhance the travel experience.
