Handheld Gimbal Fold-Position Control for Motor Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handheld gimbal control methods are cumbersome and time-consuming, requiring users to power off and restart the device to temporarily stop operations, which can damage the motor and is inconvenient for tasks like answering calls.
Innovation Solution
A control method that detects the gimbal's mode and position, automatically switching between operating and standby modes by measuring the included angle between connecting arms, allowing the gimbal to be folded without powering off, and quickly restored by unfolding, thus preventing motor damage and simplifying user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the handheld gimbal is powered off to avoid motor damage during temporary stops, then motor protection is improved, but operation convenience deteriorates
Solution Approach 1:
The system performs preliminary detection of the folded position state before motor damage can occur. By detecting the folded position in advance, the control unit proactively stops the motor, preventing damage before it happens rather than reacting after damage occurs
Solution Approach 2:
The system implements feedback through position detection sensors that continuously monitor the gimbal's folded position. This feedback loop allows the control unit to automatically adjust motor operation based on real-time position information, eliminating the need for manual power off/on operations
2Reliability
If the handheld gimbal is powered off and restarted for temporary stops, then motor damage is prevented, but time consumption increases
Solution Approach 1:
The control unit performs preliminary motor stopping based on detected folded position, preventing damage before it occurs. This eliminates the need for time-consuming power cycle operations while maintaining motor protection
Solution Approach 2:
The system serves itself by automatically detecting folded position and controlling motor stop/start operations without user intervention. The gimbal autonomously manages its own power state based on position feedback, eliminating manual power button operations
3Measurement precision
If the handheld gimbal requires APP setup for normal operation, then control precision is improved, but operation complexity increases
Solution Approach 1:
The gimbal performs self-detection of folded position and self-control of motor operations. This autonomous functionality eliminates the need for complex APP setup and configuration, allowing the device to operate normally through built-in intelligence
Solution Approach 2:
The system uses feedback from position sensors to automatically adjust control parameters and motor operations. This closed-loop control enables precise operation without requiring manual APP configuration, as the system self-adjusts based on real-time position information

AI summary
Provided are a handheld gimbal control method and control apparatus. The control method comprises the following steps: step 1) detecting a current mode of the handheld gimbal; step 2) when the handheld gimbal is in an operating mode, detecting whether the handheld gimbal is at a folding position, and when the handheld gimbal is at the folding position, enabling the handheld gimbal to enter a standby mode; and step 3) when the handheld gimbal is in the standby mode, detecting whether the handheld gimbal is at a non-folding position, and when the handheld gimbal is at the non-folding position, enabling the handheld gimbal to enter the operating mode, wherein there is no sequential order for the execution of steps 2) and 3). The control method of the present invention enables a user to rapidly and conveniently operate a handheld gimbal, without damaging an electric motor.
