Dual Wheel Mouse Module for Multi-Directional Control

The patent applies multi-functionality by enabling a single wheel to perform multiple functions through different rolling directions (forward, backward, lateral) and combinations with button presses. The wheel serves as both a scrolling mechanism and a function selection interface, eliminating the need for separate function keys while maintaining operational convenience.

The patent merges the scrolling function and function selection into a single wheel component. By combining rotational movement in multiple directions with button press combinations, the design consolidates what would traditionally require separate keys and wheel mechanisms into one integrated control element.

The patent implements multi-functionality where the single wheel and button combination can execute multiple functions through different operational modes (forward roll, backward roll, lateral roll, combined rolls). This eliminates the need for additional function keys and reduces structural complexity while maintaining versatile functionality.

The patent segments the functional capabilities into different rolling directions and combinations rather than using separate physical keys. The wheel's rotational freedom is divided into distinct motion patterns (forward, backward, lateral) that correspond to different functions, achieving versatility through motion segmentation rather than component multiplication.
