Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld gimbals face challenges in effectively tracking various sports activities due to limitations in controlling movement to capture stable and smooth images or videos, especially during rapid rotations.
Innovation Solution
A handheld gimbal control method and device that includes an input device, a processor, and axis assemblies with electric motors, allowing users to select from multiple follow modes with different speeds to control the gimbal's movement, ensuring the camera maintains a stable attitude and follows the movement of the input device or handheld member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the handheld gimbal uses a single follow mode with fixed following speed, then the control system is simple, but it cannot effectively track rapid movements during sports activities
Solution Approach 1:
The patent applies dynamics by making the following speed adjustable rather than fixed. The control system dynamically switches between multiple follow modes (first follow mode with first following speed, second follow mode with second following speed) based on the movement characteristics of the sports activity being tracked. This allows the gimbal to adapt to different tracking scenarios without requiring a completely complex control system.
Solution Approach 2:
The patent changes the parameter of following speed to have multiple discrete values instead of a single fixed value. By providing at least two different follow modes with different following speeds, the system can select appropriate speed parameters matching different sports activities, thereby improving tracking capability while maintaining relatively simple control logic.
2Speed
If the handheld gimbal uses high following speed to track rapid movements, then the tracking responsiveness is improved, but the image stability and smoothness deteriorate
Solution Approach 1:
The system dynamically adjusts the following speed based on the tracking scenario. For rapid sports movements, it switches to higher following speed modes to maintain responsiveness. For normal or slow movements, it uses lower following speed modes to maintain image stability. This dynamic adjustment resolves the contradiction between speed and stability.
Solution Approach 2:
By providing multiple follow modes with different following speed parameters, the system can select the appropriate speed parameter for each scenario. This parameter variation allows the gimbal to optimize between tracking responsiveness and image stability rather than being constrained to a single fixed speed value.
3Stability of the object's composition
If the handheld gimbal uses low following speed to maintain image stability, then the image smoothness is improved, but the tracking responsiveness to rapid movements deteriorates
Solution Approach 1:
The control system dynamically selects between multiple follow modes based on the detected movement characteristics. When rapid movements are detected during sports activities, it switches to higher following speed modes to improve tracking responsiveness. During normal or slow movements, it uses lower following speed modes to maintain image smoothness.
Solution Approach 2:
The system changes the following speed parameter according to different operating conditions. By having at least two different follow modes with different speed parameters, the gimbal can optimize tracking responsiveness when needed while maintaining image smoothness during normal operation, resolving the contradiction between these two requirements.

AI summary
A method of controlling a handheld gimbal includes obtaining an input instruction, and selecting one follow mode from a plurality of follow modes for following movement of an input device or a handheld member of the handheld gimbal based on the input instruction. The plurality of follow modes have different following speeds. The method further includes controlling movement of the handheld gimbal using the selected follow mode to follow the movement of the input device or the handheld member.
