Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If expensive autonomous control systems are installed on mobile field devices, then autonomous operation capability is improved, but capital cost increases
Solution Approach 1:
The patent employs a monocular camera as a low-cost sensing component instead of expensive multi-sensor arrays or LiDAR systems. This inexpensive optical sensor captures two-dimensional images that are then processed through AI algorithms to achieve autonomous navigation, dramatically reducing the capital cost while maintaining automation capability
Solution Approach 2:
The patent replaces complex mechanical sensing systems with an optical-based monocular camera system. Instead of using multiple cameras, radar, or LiDAR hardware, the system uses a single camera combined with computational AI methods to extract depth and spatial information, substituting hardware complexity with software intelligence
2Device complexity
If monocular camera is used for autonomous control, then device complexity is reduced, but depth perception accuracy deteriorates
Solution Approach 1:
The patent introduces AI-based image analysis algorithms as an intermediary between the monocular camera and the autonomous control system. These algorithms process the two-dimensional images to infer three-dimensional spatial relationships, acting as a computational mediator that bridges the gap between simple optical input and complex navigation requirements
Solution Approach 2:
The patent transforms two-dimensional image data into three-dimensional spatial understanding through computational processing. The AI algorithms analyze pixel patterns, edges, and features in the 2D images to reconstruct depth information and generate 3D graphical representations of the field environment, effectively adding a depth dimension through software rather than hardware
