The number of skyscraper buildings is increasing mainly in big cities. The delay of elevators in these skyscrapers has become a major problem during busy times when commuting to work or returning home. In this study, a new type of elevator operation method is proposed to reduce this subject. An elevator car (‘kago’ in Japanese) that carries passengers is lifted up with a cable and only moves up and down in an ordinary elevator. However, the elevator car can move up and down, left and right, and forward and backward in this proposed elevator system. And, the car has electric gear wheels attached to the four corners (left and right, front and back of the car). It can run on electricity. Elevators dedicated to ascending and descending (these are called main elevators in this paper) and elevators capable of normal vertical movement are installed. The main elevators are fast (high-speed elevator) and these elevators are configured to stop only on floors with many users (for example, the 1st floor, 10th floor, 20th floor, etc.). Low-speed elevators will be operated between the floors where the high-speed elevators do not stop for both ascending and descending. Though there is one elevator car in a common elevator, there are multiple elevator cars in the proposed system. When it is crowded, those elevator cars can be moved from the left and right or front and rear, and it consists of multiple cars per unit (elevator) and can move for ascending and descending. When the number of passengers of an elevator decreases, the number of cars is adjusted by evacuating the car to the left and right, front and rear areas. The multiple cars in the left/right elevator or front/back elevator on the 1st floor can be stored. And, these cars can be stored in the left/right elevators or in the front and rear elevators on the top floor. With this three-dimensional elevator system, an elevator car that reaches the top floor in an elevator that only goes up is moved to an elevator for only going down. An elevator car that has reached the bottom floor in a down-only elevator is similarly moved to an up-only elevator (like drawing a loop). In addition, cameras are installed at each top front of ascending and descending elevators (main elevator) and they can count the number of people waiting. The number of elevator cars in operation is adjusted according to the number of passengers. This method can improve the time efficiency of the elevator.
