Abstract: A stabilization mechanism for luggage is provided. The stabilization mechanism can be disposed on the bottom of a compartment of luggage and in spaced relation to wheels that are also disposed on the bottom of the compartment. The stabilization includes at least one foot that is retractable within the compartment, so that in the retracted position the volume of the luggage is substantially the same as the luggage compartment. When the at least one foot is deployed, the likelihood of tipping of the luggage is decreased, as the foot, in conjunction with the wheels, maintain the luggage in a substantially vertical position.

Abstract: Systems (102) and methods (600) for adjusting a volume of an article of manufacture (AOM). The methods involve displacing a first actuator (FA) in a first direction along tracks (308, 310) until FA (312) disengages a first track (308) and abuts a first stop mechanism (504) formed at an end (510) ofa second track (310). A first flexible insert (FFI) is unfolded so as to adjust the volume of AOM by a first amount defined by geometrical dimensions of FFI (306). A second actuator (SA) is displaced in a second direction along tracks until SA (424) abuts a second stop mechanism (432) formed at ends (454) of the tracks (420, 422). A second flexible insert (SFI) is unfolded so as to further adjust the volume of AOM by a second amount defined by geometrical dimensions of SFI (406).
