## Abstract

A method of operating a portable, foldable, and multifunctional mobility aid apparatus that assists a user in standing, sitting, and/or walking process. The apparatus has an integrated power source and is based on 4 wheels. Users can stand on it and drive it as an electric mobility device, or disable it and use it as a passive walker. The apparatus has a pair of supporting beams with adjustable width to be placed under the user armpits and support the user in standing up, sitting down, and/or moving around. The apparatus can be controlled by a control panel mounted on a pair of handles, and its functions can be controlled by the user with no need for help from another person. The apparatus can be minimized by a combination of multiple telescopic vertical minimization mechanisms and multiple folding mechanisms.

## Claims

### Claim 1

A method of reducing a volume occupied by a multifunctional mobility aid device comprising:
lowering a height of a lifting mechanism mounted to a base frame, by a bi-directional vertical motion of the lifting mechanism, via a control panel mounted to a pair of handles attached to a pair of supporting beams, the pair of supporting beams being mounted to a horizontal beam, the horizontal beam being mounted to a first side of the lifting mechanism, a second side of the lifting mechanism opposite to the first side being mounted to the base frame;
folding the pair of supporting beams to align the pair of supporting beams with the lifting mechanism;
folding a standing plate mounted to the base frame away from the base frame and toward the lifting mechanism via a hinge connecting the standing plate to the base frame;
securing the standing plate against the lifting mechanism via a magnet disposed on the lifting mechanism;
folding the base frame by folding a pair of base frame beams hinged to a central portion of the base frame toward the central portion of the base frame; and
securing the base frame in a folded position by a locking mechanism.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
folding the pair of supporting beams having hollow cavities with square-shaped cross sections by sliding the pair of supporting beams from a pair of first segments of the horizontal beam to a pair of second segments of the horizontal beam, the pair of first segments of the horizontal beam having square-shaped cross sections adapted to be received by the hollow cavity, the pair of second segments of the horizontal beam having cylindrical cross sections.
