Solution Overview

Problem

Conventional handheld gimbals require continuous user input to maintain rolling and flipping movements of the imaging device, leading to inflexible and inconvenient operation.

Innovation Solution

A method and system for a handheld gimbal that allows the imaging device to start and continue a rolling rotation automatically upon detection of a predetermined trigger signal, eliminating the need for continuous user button pressing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If continuous button pressing is required to maintain rolling and flipping movements, then the imaging device can perform controlled rotations, but the user operation becomes inflexible and inconvenient

Engineering Contradiction:

Improveuser operation flexibilityVSAvoidcontrol operation complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies periodic action by using intermittent trigger signals to control the imaging device's rolling and flipping movements. Instead of requiring continuous button pressing, the system responds to periodic trigger signals that activate motors for specific durations, enabling controlled rotations through discrete, rhythmic input rather than sustained pressure.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system implements self-service by automatically maintaining rolling and flipping movements once initiated by a trigger signal. The control mechanism continues to operate without requiring continuous user input, allowing the imaging device to perform sustained rotations autonomously after the initial trigger, thereby improving operational flexibility and reducing user burden.

Inventive Principle:

Principle #25Self-service

2Duration of action of moving object

If a control button is pressed continuously to maintain rolling and flipping, then the imaging device remains in motion, but the user must maintain constant physical input

Engineering Contradiction:

Improveduration of rolling rotationVSAvoiduser input requirement

Core Design Contradiction:

Duration of action of moving objectVSEase of operation

Solution Approach 1:

The patent uses periodic action by implementing a control system that responds to intermittent trigger signals rather than continuous pressure. The motor receives pulsed control signals that initiate and maintain rolling rotations for specific time intervals, allowing the imaging device to perform sustained movements through periodic rather than continuous user input.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system applies self-service by automatically maintaining the rolling and flipping movements once triggered. The control mechanism continues operating the motor without requiring the user to hold the button down, enabling the imaging device to sustain its motion autonomously after the initial trigger signal is received.

Inventive Principle:

Principle #25Self-service

AI summary

The present disclosure provides a handheld gimbal control method and a handheld gimbal. The method includes: acquiring an input signal (S301); and performing a first control operation triggered by a first trigger signal in response to the input signal being a predetermined first trigger signal, where the first control operation is used to control the yaw axis motor disposed on the handheld gimbal to start and continue to work so as to enable the imaging device carried by the handheld gimbal to start and continue a rolling rotation (S302). The control method relieves a user from pressing the control button on the handle at all times, thereby improving the flexibility of user operation and user experience.
