A new design mobile cabin hospital based on the Hoberman sphere

Abstract

Mobile cabin hospitals have been established in many countries and regions to cope with the spread of the new crown epidemic. The feasibility and convenience of the model are analyzed in the context of practical situations. This paper examines and exploits the collapsibility and convenience of Hoberman spheres, their principles and methods of movement, and the dynamics of the scissor structure, which is the basic unit of movement of Hoberman spheres. The effect of changes in angle as well as the length of the scissor-like structure leading to the size of the sphere is analyzed. It was also studied and analyzed through specific model designs, what materials are more suitable for the lining material. The resulting design for the individual wards of the mobile cabin hospital was constructed from half of the Hoberman spherical shell and covered with protective material inside. The final optimization of the combination makes it innovative. The design objectives were simple, easy to install and transport, and reusable.
