Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If consumer-grade cameras are modified for aerial mapping, then the camera can be used in drone applications, but the camera produces jelly effect and has unstable operation due to incomplete modification
Solution Approach 1:
The patent extracts and removes redundant components from the modified camera system, including the original lens assembly, shutter mechanisms, and other unnecessary parts. By taking out only the essential imaging components (sensor module and housing) and discarding the rest, the system achieves both adaptability for drone use and operational stability through complete modification.
2Adaptability or versatility
If consumer-grade cameras are modified by removing outer shell and peripheral parts, then the camera can be adapted for aerial mapping, but the camera becomes heavy and large due to redundant parts
Solution Approach 1:
The patent extracts and removes the outer shell, peripheral electronic components, and structural parts from the consumer-grade camera. By taking out only the essential imaging components (sensor module and housing) and discarding the rest, the system achieves both adaptability for drone use and reduced weight.
Solution Approach 2:
The patent segments the camera system into essential components (imaging sensor module and housing) and non-essential components (outer shell, peripheral parts). By separating and removing the non-essential segments, the system achieves weight reduction while maintaining core functionality for aerial mapping.
3Ease of operation
If consumer-grade cameras with rolling shutters are used, then the camera can capture images, but the camera produces jelly effect when the drone is in motion
Solution Approach 1:
The patent extracts and removes the rolling shutter mechanism from the camera system. By taking out the problematic shutter component and replacing it with a global shutter implementation, the system maintains image capture capability while eliminating the jelly effect that degrades photography accuracy during drone motion.
