Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gimbals experience gimbal lock due to axis interference, limiting shooting composition and preventing effective voice information collection and user voice command recognition.
Innovation Solution
A gimbal design with a stand, first axis compensator for yaw motion, second axis compensator for pitch motion, and third axis compensator for roll motion, connected sequentially to prevent axis interference, incorporating a microphone module for voice command reception and sound signal collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a 3-axis gimbal with yaw-roll-pitch sequence is used, then the gimbal can maintain balance and perform tracking shots, but gimbal lock occurs in vertical position limiting shooting composition
Solution Approach 1:
The patent implements dynamic axis sequence switching based on the gimbal's orientation. When the gimbal detects it is in a vertical position, it automatically switches from the yaw-roll-pitch sequence to a yaw-pitch-roll sequence, preventing gimbal lock. This dynamic adaptation allows the system to maintain full 3-axis functionality across all orientations, resolving the contradiction between reliability in tracking and adaptability in shooting composition.
2Device complexity
If the gimbal uses a fixed axis sequence, then the structure is simple, but voice information collection is ineffective and voice command recognition is not enabled
Solution Approach 1:
The patent integrates a microphone module into the gimbal system, enabling it to perform multiple functions: traditional balance maintenance, tracking shots, and voice information collection. The controller processes both motion control signals and audio signals, allowing the gimbal to function as both a stabilization device and a voice-activated control system, thus reducing information loss without significantly increasing structural complexity.
3Device complexity
If the gimbal does not include voice recognition functionality, then the device is simpler, but user voice commands cannot be recognized and executed
Solution Approach 1:
The patent replaces manual mechanical control operations with voice-based control. The microphone module captures voice commands, and the controller processes these audio signals to execute corresponding gimbal movements. This substitution of mechanical hand-control with acoustic voice-control significantly improves ease of operation, allowing users to control the gimbal hands-free while adding only minimal functional complexity.
