Gimbal Sleep-Mode Angle Holding for Push-Pull Frame Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gimbals require users to manually dismount the mobile terminal for operation, leading to inconvenient handling and potential swinging during use.
Innovation Solution
A control method and gimbal system that allows users to adjust the gimbal's frames to desired positions through push-pull operations, using a processor to determine and maintain target joint angles during a sleeping mode, enabling convenient operation without dismounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the cellphone is tightly clamped by the gimbal to ensure stable mounting, then the mounting stability is improved, but the ease of operation deteriorates because the user cannot quickly dismount the cellphone for operations like making calls or browsing images
Solution Approach 1:
The gimbal system dynamically switches between different operational modes (stabilization mode and sleeping mode) based on user interaction. In stabilization mode, the clamp provides strong holding force for stable mounting. In sleeping mode, the clamp releases to allow easy dismounting. This dynamic mode switching resolves the contradiction between stable mounting and ease of dismounting.
Solution Approach 2:
The clamp force parameter is changed based on the operational mode. In stabilization mode, the clamp force is high to ensure stable mounting. In sleeping mode, the clamp force is reduced or released to enable easy dismounting. This parameter change allows the system to satisfy both stable mounting and ease of operation requirements at different times.
2Productivity
If the gimbal is closed without the cellphone being dismounted to save time, then the productivity is improved, but the stability deteriorates because the motor stops providing power and the frames swing back and forth
Solution Approach 1:
The system performs preliminary action by maintaining the motor's power provision and stabilization function even when the gimbal is being closed. The motor continues to provide power during the closing process, preventing frame swinging. This allows the user to close the gimbal quickly without compromising stability, as the stabilization mechanism remains active during the transition.
Solution Approach 2:
The useful action of motor power provision and frame stabilization continues even during the closing process. The motor does not stop providing power when the gimbal is closed, ensuring continuous stabilization and preventing frame swinging. This continuity allows fast closing while maintaining stability throughout the entire process.
3Stability of the object's composition
If the user holds the cellphone and the gimbal handle simultaneously to prevent swinging during operation, then the frame stability is improved, but the ease of operation deteriorates because it becomes very inconvenient to operate the cellphone
Solution Approach 1:
The system dynamically switches to sleeping mode when the user needs to operate the cellphone. In this mode, the clamp releases the cellphone, allowing the user to hold it freely with one hand. The motor continues to provide stabilization, preventing frame swinging. This dynamic mode change resolves the contradiction by enabling easy cellphone operation while maintaining frame stability through continued motor support.

AI summary
A control method of a gimbal includes in response to the gimbal being in a sleeping mode and receiving a push-pull operation on a frame of the gimbal, obtaining a current target joint angle according to an actual joint angle of a motor arranged at the frame and configured to rotate the frame and controlling the motor according to the current target joint angle. The actual joint angle corresponds to a position where the push-pull operation reaches.
