Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a road surface state sensor is used to sense a dried state of a road with applied paint, then the sensor can provide road surface state information, but the sensed information includes a high ratio of error values reducing reliability
Solution Approach 1:
The patent introduces an image processing system as an intermediary to detect paint presence on the road surface. The camera captures images, and image processing algorithms determine whether paint is present. This intermediary detection mechanism allows the system to identify when the road surface sensor is operating on painted sections and generate warnings accordingly, resolving the reliability issue without modifying the sensor itself.
2Reliability
If image processing is used to detect paint presence, then the system can identify painted road sections, but the device complexity increases
Solution Approach 1:
The patent utilizes a camera, which is a common component in mobile devices, to perform multiple functions: capturing images for paint detection and potentially other monitoring tasks. By leveraging an existing multi-functional component rather than adding specialized equipment, the system achieves reliable paint detection while minimizing the increase in device complexity.
