Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fragment detection methods are used, then detection capability is achieved, but device complexity and space requirements increase
Solution Approach 1:
The detection device is segmented into independent light sources and photosensitive elements positioned at opposite edges of the panel, allowing modular configuration and simplified installation while maintaining effective fragment detection capability across the display surface
Solution Approach 2:
The detection function is extracted from complex traditional detection systems and implemented using simple optical components (light sources and photosensitive elements) positioned at panel edges, eliminating the need for complex internal detection structures
2Measurement precision
If comprehensive panel coverage detection is implemented, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The detection approach transitions from one-dimensional linear arrays to two-dimensional edge positioning, where light sources and photosensitive elements are arranged on opposite edges to create cross-panel optical paths that enable accurate fragment position determination through geometric intersection calculations
3Reliability
If timely fragment detection is achieved, then panel damage prevention improves, but detection system complexity increases
Solution Approach 1:
The detection system uses the panel's own edge structures to position the light sources and photosensitive elements, eliminating the need for separate mounting structures and simplifying integration while enabling continuous monitoring for timely fragment detection
