Handheld Gimbal Attitude Control for Instant Photo Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld gimbals cannot directly enter down flashlight mode or vertical photograph mode, requiring manual adjustment which is complex and inefficient, often resulting in missed photographing moments.
Innovation Solution
A control method and handheld gimbal system that automatically determines the expected photograph mode based on the handle's attitude, allowing the gimbal to directly enter modes such as up flashlight, vertical, forward, reverse, and down flashlight modes without additional user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment is used to switch photograph modes, then the gimbal can enter down flashlight mode or vertical photograph mode, but the operation becomes complex and inefficient
Solution Approach 1:
The gimbal system automatically detects the handle's attitude through sensors and autonomously determines the appropriate photograph mode without requiring user intervention. The controller compares the detected attitude with predefined mode conditions and automatically switches modes, allowing the system to serve itself rather than requiring manual operation.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated electronic control system. Sensors detect the handle's spatial orientation, and a controller processes this data to automatically select and switch photograph modes, substituting the mechanical manual adjustment process with an electronic sensing and control system.
2Productivity
If manual adjustment is used to switch photograph modes, then mode changes are possible, but the efficiency is low and photographing moments are missed
Solution Approach 1:
The system pre-establishes multiple photograph modes (down flashlight mode, vertical photograph mode, etc.) with predefined attitude conditions. When the handle's attitude matches a predefined condition, the corresponding mode is automatically activated, allowing the system to be prepared in advance for different shooting scenarios and respond immediately when conditions are met.
Solution Approach 2:
The system continuously monitors the handle's attitude through sensors and provides real-time feedback to the controller. Based on this feedback, the controller automatically adjusts the photograph mode to match the current handle orientation, creating a closed-loop control system that responds dynamically to user movements and maintains optimal shooting posture.

AI summary
A control method of a gimbal device includes in response to a gimbal entering a movement status, obtaining an attitude of a support member, and in response to the attitude of the support member being an attitude corresponding to an expected photograph mode, controlling the gimbal to enter the expected photograph mode, including controlling the gimbal to rotate, to cause a specific plane in a coordinate system of an imaging device and a vertical direction to satisfy a position relationship. The specific plane is formed based on a first axis direction and a second axis direction in the coordinate system of the imaging device. In response to the imaging device being positioned substantially upright, the first axis direction and the second axis direction are substantially perpendicular to the vertical direction.
