Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection is used for artifact detection, then detection accuracy can be maintained through human expertise, but processing time increases exponentially with data volume
Solution Approach 1:
The patent replaces the manual mechanical inspection process with an automated machine learning system. The artifact detection model processes video frames and images automatically, substituting human operators with computational algorithms that can handle large volumes of data without proportional increases in processing time.
Solution Approach 2:
The patent generates synthetic artifact data by copying and transforming real artifact patterns. Synthetic artifacts are created by applying transformations to real artifact examples, enabling the model to learn from expanded training data without requiring proportional increases in manual annotation time.
2Manufacturing precision
If image and video resolutions are increased to improve quality, then visual accuracy improves, but the volume of data requiring inspection grows exponentially
Solution Approach 1:
The patent processes video data in temporal sequences rather than as static individual frames. By analyzing multiple frames together and leveraging temporal information, the system can detect artifacts more efficiently across high-resolution video content without processing each frame independently, thus reducing the effective data volume burden.
Solution Approach 2:
The patent performs preliminary processing of video data by extracting key frames and generating synthetic training data before the main detection process. This preliminary action prepares the data in advance, reducing the computational burden during actual artifact detection and enabling efficient processing of high-resolution content.
3Reliability
If more QC operators are hired to inspect increasing volumes of content, then detection coverage improves, but operational costs and complexity increase
Solution Approach 1:
The artifact detection model is designed to handle multiple types of artifacts (hot pixels, compression artifacts, sensor noise, dead pixels) and various media types (video, images) with a single unified system. This multi-functional approach eliminates the need for separate inspection processes for different artifact types, reducing operational complexity while maintaining comprehensive detection coverage.
4Adaptability or versatility
If manual inspection processes are used, then flexibility in handling various artifact types is maintained, but processing speed decreases
Solution Approach 1:
The patent uses synthetic data generation with adjustable parameters to adapt the training process to different artifact types and conditions. By modifying parameters such as artifact intensity, size, and distribution in synthetic training data, the model learns to handle various artifact types efficiently, maintaining flexibility while achieving high processing speeds through automated computation.
