Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual detection method is used to detect display failures, then the detection process is simple to implement, but the detection accuracy is low and labor cost is high
Solution Approach 1:
The patent replaces manual mechanical detection with an automated image processing system. An image acquisition device captures display screen images, and image processing algorithms automatically analyze the images to detect failures such as black blocks, bright blocks, and blank screens. This substitution of mechanical/manual inspection with automated optical and computational methods resolves the contradiction by significantly improving detection accuracy while managing system complexity through software-based solutions.
2Productivity
If manual detection method is used to detect display failures, then the system structure is simple, but the detection efficiency is low and labor cost is high
Solution Approach 1:
The patent implements a self-service detection system where the display device automatically captures its own display output through an integrated image acquisition device, processes the images through embedded algorithms, and generates failure detection results without external intervention. This self-service approach dramatically improves detection efficiency by enabling continuous automated monitoring while containing system complexity within the display device itself.
Solution Approach 2:
The patent replaces manual inspection processes with automated image capture and processing systems. The image acquisition device continuously captures display screens, and computational algorithms automatically analyze the images to identify failures. This mechanical-to-automated substitution resolves the contradiction by enabling high-speed continuous detection while managing complexity through software-based image processing pipelines.
3Reliability
If remote display screen failures are not detected timely, then the system operation is simple, but the playing effect is negatively impacted
Solution Approach 1:
The patent implements a feedback mechanism where the image processing system continuously monitors display output and provides real-time feedback about detected failures. When abnormalities such as black blocks or bright blocks are detected, the system generates alerts or logs failure information, enabling timely response and maintenance. This feedback loop ensures high reliability by immediately notifying operators of display issues while managing complexity through automated monitoring and reporting systems.
