Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a physical camera platform with motors is used to enable two-dimensional movement of the camera, then image capture capability is improved, but device weight and volume increase
Solution Approach 1:
The patent merges the camera platform, motors, and image processing functions into a single integrated controller chip. This consolidation eliminates the need for separate mechanical components while maintaining image capture and stabilization capabilities, directly reducing UAV weight without sacrificing imaging functionality
Solution Approach 2:
The patent replaces the mechanical camera platform system with motors and gears with an electronic solution implemented in a controller chip. Image stabilization is achieved through electronic processing rather than mechanical movement, eliminating heavy mechanical components while preserving image quality
2Measurement precision
If a physical camera platform with motors is used to enable two-dimensional movement of the camera, then image capture capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple separate modules (camera platform control, image processing, flight control) into a single integrated controller chip. This consolidation simplifies the overall circuit structure by reducing the number of separate components and their interconnections, while maintaining all necessary functionalities
Solution Approach 2:
The controller chip is designed to perform multiple functions including image capture, image stabilization processing, and flight control. This multi-functionality eliminates the need for dedicated separate modules for each function, thereby reducing circuit complexity while enhancing overall system capability
3Ease of operation
If a camera platform control module is used to control the motors, then camera movement control is improved, but power consumption increases
Solution Approach 1:
The patent replaces the motor-driven mechanical camera movement system with an electronic image stabilization system controlled by a controller chip. This substitution eliminates continuous motor operation, significantly reducing power consumption while maintaining the ability to control and stabilize camera imaging
Solution Approach 2:
Instead of continuous motor operation to maintain camera position, the system uses periodic image capture and electronic processing to achieve stabilization. This approach consumes energy only during image capture intervals rather than continuously, reducing overall power consumption
