1Reliability

If manual inspection is used for artifact detection, then detection accuracy can be maintained through human expertise, but processing time increases and productivity decreases

Engineering Contradiction:
Improvedetection accuracyVSAvoidprocessing speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical human inspection system with an automated machine learning system comprising convolutional neural networks and artifact detection models. This substitution maintains detection accuracy through trained algorithms while dramatically increasing processing speed and productivity by automatically analyzing video frames without human intervention.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The artifact detection system performs self-service by automatically detecting, localizing, and classifying artifacts in video content without requiring manual inspection. The machine learning model independently processes video frames, identifies artifacts based on learned patterns, and generates detection results, eliminating the need for human operators while maintaining consistent accuracy.

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If image and video resolutions increase to improve quality, then manufacturing precision improves, but the complexity of detection and measurement increases

Engineering Contradiction:
Improveimage qualityVSAvoidartifact detection complexity
Core Design Contradiction:
Manufacturing precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The patent segments the high-resolution video content into individual frames and further segments artifact detection into multiple processing stages using different convolutional blocks. The first convolutional block processes initial features, the second and third blocks refine bottleneck features, and the fourth and fifth blocks generate final artifact detections. This segmentation makes detecting artifacts in high-resolution content manageable by breaking down the complex task into smaller, parallelizable operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an additional processing dimension by implementing a multi-block convolutional architecture that processes video data through multiple transformation stages. Instead of attempting to detect artifacts directly in high-resolution space, the system transforms the data through multiple convolutional blocks that operate in feature space, effectively adding a dimensional layer to the detection process that simplifies the identification of artifacts regardless of input resolution.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Productivity

If manual inspection is replaced with automated systems, then productivity increases, but device complexity increases

Engineering Contradiction:
Improvedetection throughputVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements a universal artifact detection model that can identify multiple types of artifacts (compression artifacts, noise, distortion, etc.) across different video resolutions and formats using a single multi-block convolutional architecture. This universal system handles diverse artifact types and input conditions through the same five convolutional blocks, reducing the need for multiple specialized systems and thereby managing complexity while maintaining high productivity across various video content types.

Inventive Principle:
Principle #6Universality (Multi-functionality)
