Motorized Collapsible Shopping Trolley With Multi-Directional Wheels

The patent replaces the purely mechanical manual cart system with an electromechanical system. An electric motor is integrated into the cart to provide automated propulsion, substituting human physical effort with electrical power. The motor is controlled via a handheld remote or integrated controls, allowing users to operate the cart without exerting significant force, thereby resolving the contradiction between ease of operation and force required.

The cart is designed to propel itself autonomously using an integrated electric motor and battery system. The motor automatically drives the wheels based on user input through simple controls, eliminating the need for the user to manually push or pull the cart. This self-service capability allows the cart to perform the propulsion function independently, reducing the physical effort required by the user.

The patent implements a dynamic wheel system where the wheels can change their orientation and function. The rear wheels are equipped with mechanisms that allow them to rotate or pivot, enabling the cart to move not only forward and backward but also sideways. This dynamic configuration allows the cart to adapt to different navigation needs and spatial constraints, increasing versatility while managing complexity through controlled mechanical movement.

The wheel system is divided into independent, controllable units. Each wheel or wheel assembly can be individually actuated or oriented, allowing selective engagement of different movement modes. This segmentation enables the complex multi-directional movement capability to be achieved through coordinated action of separate wheel modules, making the complexity manageable and the adaptability achievable.
