Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed control method is used for the gimbal, then the control system is simple and easy to operate, but the image stability deteriorates when the focal length changes
Solution Approach 1:
The patent applies dynamics by transitioning from fixed control parameters to dynamic control parameters that adapt to changing focal lengths. The control system now adjusts gimbal speed, acceleration, and dead-zone parameters based on the current focal length, making the control characteristics variable rather than static. This resolves the contradiction by maintaining ease of operation through automated adaptation while improving image stability through context-aware control adjustments.
Solution Approach 2:
The patent implements parameter changes by modifying control parameters (speed, acceleration, dead-zone) according to the focal length. When focal length changes, the system automatically adjusts these parameters to maintain optimal image stability. This directly addresses the contradiction by allowing the control system to adapt its parameters dynamically, ensuring reliable image output across different focal lengths without complicating the user interface.
2Device complexity
If the gimbal control system and camera control system are independent, then the device complexity is reduced, but the image stability deteriorates due to inability to coordinate movements
Solution Approach 1:
The patent applies merging by integrating the gimbal control system with the camera control system through focal length coordination. While the systems remain physically separate, they are functionally coupled through shared focal length information and coordinated control parameters. This resolves the contradiction by achieving image stability through system coordination without creating a fully integrated complex control architecture, maintaining relative simplicity while improving reliability.
Solution Approach 2:
The patent implements feedback by using focal length information from the camera to adjust gimbal control parameters. The system continuously monitors focal length changes and feeds this information back to the gimbal controller, which then adjusts speed, acceleration, and dead-zone parameters accordingly. This feedback mechanism ensures image stability without requiring a fully merged control system, balancing complexity and reliability.
3Device complexity
If fixed speed and acceleration control is used, then the control method is simple, but the image stability deteriorates when focal length varies
Solution Approach 1:
The patent applies dynamics by making control speed and acceleration variable based on focal length. Instead of fixed values, the system now uses dynamic parameters that automatically adjust when focal length changes. This resolves the contradiction by maintaining simple control methodology through automated parameter selection while improving image stability through focal length-adaptive speed and acceleration control.
Solution Approach 2:
The patent implements parameter changes by modifying speed and acceleration parameters according to focal length variations. The system stores multiple sets of control parameters corresponding to different focal lengths and automatically selects the appropriate parameters when focal length changes occur. This approach maintains control simplicity through automated parameter management while ensuring image stability through context-appropriate parameter selection.
