Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the height difference method is used to measure screen wrinkles, then the measurement is simple and objective, but the detection result does not match human visual perception
Solution Approach 1:
The patent introduces a beam splitter as an intermediary optical component to redirect detection light vertically onto the screen surface. This allows the detection system to simulate human frontal observation without requiring direct access to the back of the screen, resolving the contradiction between measurement simplicity and visual perception accuracy
Solution Approach 2:
The patent replaces the conventional mechanical height difference measurement method with an optical reflection-based detection system. By using light reflection angles and image analysis, the system achieves visual-perception-aligned wrinkle detection without complex mechanical measurement apparatus
2Ease of operation
If conventional measurement methods are used, then the detection process is straightforward, but the results do not align with frontal visual observation
Solution Approach 1:
The patent changes the detection dimension by observing light reflection from the screen surface at vertical incidence. This dimensional change in light propagation direction enables the system to capture wrinkle information that correlates with human frontal visual perception while maintaining operational simplicity
Solution Approach 2:
The patent changes the detection parameter from direct height measurement to light reflection angle analysis. By measuring how wrinkles affect reflected light patterns, the system achieves results that match visual perception while keeping the detection process straightforward
