In-Plane Rotating Sign Mechanism for Attention Capture

The patent applies the dynamics principle by transforming the static billboard into a movable one that can rotate in-plane. The sign is mounted on a rotating mechanism that allows it to change orientation periodically, creating motion that captures passerby attention while maintaining the simplicity of the basic billboard structure for easy manufacture and maintenance.

The patent implements periodic action through the rotating mechanism that periodically changes the sign's orientation. The sign rotates back and forth or continuously, creating periodic motion that repeatedly draws attention from passersby, thereby improving effectiveness without complicating the overall system.

The patent uses the dynamics principle to achieve visible change through in-plane rotation of the sign. This rotational movement creates dynamic visual interest that draws attention, while the rotation mechanism itself remains relatively simple, avoiding excessive construction complexity.

The patent applies dimensionality change by introducing rotational movement in the horizontal plane rather than vertical movement. This in-plane rotation adds a new dimension of motion that captures attention effectively while using simpler mechanical components compared to vertical lifting or complex three-dimensional transformations.

The patent implements periodic action by having the sign rotate back and forth between predetermined angular positions rather than rotating continuously in one direction. This periodic motion maintains attention-capturing effectiveness while reducing energy consumption and mechanical wear compared to continuous rotation.

The patent applies partial action by rotating the sign only through necessary angular ranges sufficient to capture attention, rather than full 360-degree continuous rotation. This partial rotation achieves the attention-capturing goal while minimizing energy consumption and mechanical stress.
