V-Angled Spinner Wheel Assembly for Quiet, Stable Luggage Rolling

The patent applies asymmetry by configuring the wheels at different angles relative to the direction of travel. The first wheel is angled at a first angle and the second wheel is angled at a second angle, creating an asymmetric V-configuration that provides mechanical advantage for turning while maintaining straight-line tracking stability. This asymmetric arrangement resolves the contradiction by enabling easy maneuverability without compromising tracking or generating noise.

The patent extracts and eliminates the need for heavy ball bearings or bushings by using a simplified strut-based wheel assembly. The invention achieves smooth rolling efficiency through the geometric V-configuration of the wheels and the rotatable strut mechanism, removing the harmful element of heavy bearings while maintaining or improving rolling performance. This resolves the contradiction by achieving high productivity without the weight penalty.

The patent applies dimensionality change by transitioning from a vertical wheel orientation to an angled V-configuration. This angular arrangement in a different dimensional orientation prevents debris from being trapped between the wheels, as the angled surfaces naturally shed debris. The solution maintains mobility while eliminating the debris accumulation problem that reduces rolling efficiency.
