Gimbal Rocker Control for Single-Operator Direction and Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gimbals used in video shooting, photo taking, and surveillance often have a bad hand feeling and are inconvenient to operate due to the use of multiple keypads or remote controllers for wireless control, leading to low accuracy and requiring multiple persons for handheld operation.
Innovation Solution
A gimbal system featuring a rocker with potentiometers for receiving action instructions and sending control instructions to a controlling assembly, which implements directional controls for optical devices, allowing for easy operation and a good hand feeling through a single-person control mechanism with modes like follow and locked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple keypads or remote controller are used for wireless control, then the gimbal can be controlled directionally, but the hand feeling becomes bad and operation accuracy decreases
Solution Approach 1:
The patent combines multiple control functions (pitch control, rotation control, and mode switching) into a single integrated rocker control device. The rocker includes a handle that can be tilted in multiple directions and pressed, replacing the need for separate keypads and remote controllers. This merging of control functions into one device improves hand feeling and operation accuracy while reducing device complexity.
2Ease of operation
If remote controller is used for wireless control, then directional actions can be controlled, but it requires a receiver and multiple persons for operation
Solution Approach 1:
The patent extracts the control function from the gimbal system itself and places it in a separate, handheld rocker device. This allows the control functionality to be independent of the gimbal, enabling single-person operation without requiring a receiver to be integrated into the gimbal structure. The rocker can be wirelessly connected or directly connected, but the control capability is now separated and portable.
3Ease of operation
If multiple keypads are used to control pitch and rotation angles, then directional control is achieved, but hand feeling becomes bad
Solution Approach 1:
The rocker control device is designed with multi-functionality: it can control pitch by tilting forward/backward, control rotation by tilting left/right, and switch operating modes by pressing. This single device performs all control functions that previously required multiple separate keypads, improving hand feeling while maintaining comprehensive control capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The gimbal system provides easy operation and a good hand feeling, enabling single-person control of optical devices with improved accuracy and convenience, as the rocker-based control system simplifies directional adjustments and mode switching.
Implementation Method 1
a potentiometer assembly connected with the rocker handle

AI summary
A gimbal includes a control device configured to receive an action instruction including a press action instruction and, based on the action instruction, generate a control instruction including a switch control instruction for switching operating modes of the gimbal, a controlling assembly configured to receive the control instruction and generate a performing instruction based on the control instruction for controlling an optical device, and a performing assembly configured to receive and implement the performing instruction. The performing assembly is operably connected to the controlling assembly and supported on a top end of a support arm of the control device. The performing assembly comprises a first rotation member, a second rotation member, and a carrying member connected one to another, and first and second motors for driving the second rotation member and the carrying member to rotate relative to the first and second rotation members, respectively.
