Hanger Vibration Module Using Counter-Rotating Eccentrics

The patent applies the counterweight principle by introducing a second eccentric portion that rotates in the opposite direction to the first eccentric portion. The centrifugal forces generated by the two eccentric portions in directions perpendicular to the intended vibration direction are made equal and opposite, causing them to cancel each other out. This eliminates unnecessary vibrations in directions other than the intended vibration direction while maintaining sufficient excitation force in the desired direction.

The patent applies the dynamics principle by making the amplitude of vibration variable rather than constant. The control unit adjusts both the vibration frequency and amplitude dynamically based on the operating mode. When the vibration frequency changes, the amplitude is simultaneously adjusted to prevent excessive stress on items, while still maintaining effective wrinkle removal. This dynamic adjustment allows the system to adapt to different conditions and avoid the harmful effects of constant amplitude during frequency transitions.

The patent applies the dynamics principle by implementing variable amplitude control. The control unit adjusts the vibration amplitude dynamically based on the selected operating mode and current operating conditions. This allows the system to optimize wrinkle removal efficiency by increasing amplitude when needed while preventing excessive stress on items by reducing amplitude when appropriate, particularly during frequency transitions or when handling delicate items.
