Foldable Phone Gimbal Arm Structure for Compact Carrying

The patent applies the dynamics principle by making the gimbal structure foldable rather than fixed. The second arm can be rotated relative to the first arm, allowing the gimbal to transition between an extended operational state and a compact folded state. This dynamic configuration enables the gimbal to maintain stability during photography when extended, while reducing its volume for portability when folded and stored.

The patent applies segmentation by dividing the gimbal into multiple separable arms (first arm and second arm) that can be independently positioned. The second arm is rotatably connected to the first arm, allowing it to be folded back during storage. This segmentation enables the long arm structure needed for stability to be broken into foldable segments that reduce overall volume when not in use.

The patent uses a rotatable connection between the first arm and second arm, which provides a simple mechanical hinge mechanism. This dynamic joint allows the second arm to be folded back during storage while maintaining structural integrity during operation, achieving volume reduction without requiring complex disassembly or multiple connection mechanisms.

The patent combines the functions of the first arm and second arm into a single integrated gimbal structure that can be folded. Rather than using separate detachable components or complex locking mechanisms, the rotatable connection merges the arms into one unified structure that automatically maintains its configuration during use and folds compactly for storage.
