Handheld Gimbal Handle Attitude Sensing for Direct Photo Mode Entry
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 opportunities.
Innovation Solution
A control method for a handheld gimbal that determines the expected photograph mode based on the handle's attitude by calculating included angles between different directions and the vertical direction, allowing the gimbal to automatically enter modes such as up flashlight, vertical, down flashlight, forward, or reverse modes when it enters a movement status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment is used to switch photograph modes, then the gimbal can enter desired modes, but the operation becomes complex and inefficient
Solution Approach 1:
The gimbal system automatically determines photograph modes based on handle attitude without requiring user intervention. The controller detects the handle's orientation using sensors, calculates the included angles with vertical direction, and autonomously switches between photograph modes (up flashlight, down flashlight, vertical, forward, reverse), making the system self-serve the mode switching function.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automatic control system. Sensors detect the handle's spatial orientation, the controller processes this data to determine attitude angles, and actuators automatically adjust the gimbal to the correct photograph mode, substituting the mechanical manual operation with an automated sensing-control-actuation system.
2Productivity
If automatic mode switching is implemented, then operation efficiency is improved, but device complexity increases
Solution Approach 1:
The controller serves multiple functions: it manages gimbal stabilization, processes sensor data for attitude detection, calculates included angles with vertical direction, determines the appropriate photograph mode, and controls mode switching. By making the controller a multi-functional universal component, the patent avoids adding separate dedicated hardware for each function, thereby limiting the increase in device complexity while achieving automatic mode switching.
Solution Approach 2:
The patent introduces an intermediary computational layer between sensor detection and mode execution. The controller acts as a mediator that receives raw attitude data from sensors, processes this information through angle calculation algorithms, and translates it into mode switching commands. This intermediary processing simplifies the overall system architecture by centralizing the decision-making logic in a single control unit rather than requiring complex direct coupling between multiple specialized components.

AI summary
A control method of a handheld gimbal includes, in response to a gimbal of the handheld gimbal entering a movement status, obtaining an attitude of a handle of the handheld gimbal that carries the gimbal, determining an expected photograph mode from a plurality of photograph modes according to the attitude of the handle, and controlling the gimbal to enter the expected photograph mode. The plurality of photograph modes comprise an up flashlight mode, a vertical photograph mode, a forward photograph mode, a reverse photograph mode, and a down flashlight mode.
