Suitcase-Integrated Foldable Scooter for Micro-Mobility: A Hybrid Mobility Solution for Urban and Transit Use

Abstract

The rapid growth of urban population and infrastructure has led to significant challenges in transportation systems, particularly in terms of traffic congestion, limited parking availability, and inefficient last-mile connectivity. Commuters frequently experience difficulty in covering short distances within transit environments such as airports, metro stations, and educational campuses, especially when handling personal luggage. This highlights the need for an integrated, compact, and efficient mobility solution. This paper proposes a suitcase-integrated foldable scooter, a hybrid system that combines personal transportation with luggage functionality. The system is designed to enable seamless transition between walking and riding modes, thereby enhancing user convenience and reducing physical effort. The design incorporates a foldable scissor mechanism, a telescopic handlebar, and a compact electric drive system consisting of a BLDC hub motor powered by a lithium-ion battery.

The development process involves material selection, structural design, and CAD-based modeling to ensure optimal strength, durability, and portability. Analytical studies, including stress analysis and load distribution, were performed to evaluate the structural integrity of the system. Experimental testing was conducted to assess key performance parameters such as folding time, ride stability, load capacity, and battery efficiency. The results demonstrate that the proposed system effectively improves mobility in congested urban environments while reducing dependency on conventional transport methods. The integration of luggage and mobility into a single unit enhances space utilization and promotes sustainable transportation practices.

In conclusion, the suitcase-integrated foldable scooter represents a promising advancement in micro-mobility solutions. While certain limitations related to structural stability and weight optimization exist, further improvements in material technology and design can enhance its performance and usability. The system has strong potential for application in smart cities and modern transportation networks.
