Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a front camera is used for facial recognition, then recognition function is provided, but the bezel width increases and device complexity increases
Solution Approach 1:
The patent merges the facial recognition function with the display panel by integrating infrared emitting units and receiving units directly into the display area. This combines two separate functions (display and facial recognition) into a single integrated component, eliminating the need for a separate front camera assembly and reducing overall device complexity.
Solution Approach 2:
The display panel is given multiple functions: it serves both as the visual display interface and as the facial recognition sensor array. The infrared emitting units and receiving units are distributed across the display area, allowing the same physical structure to perform both display and recognition tasks simultaneously.
2Measurement precision
If more infrared emitting units and receiving units are added, then recognition precision is improved, but the display area is reduced
Solution Approach 1:
The patent segments the display area into multiple pixel sub-regions, with each sub-region containing a combination of sub-pixel units and infrared units. This segmentation allows the infrared units to be distributed across the entire display area rather than concentrated in one location, maximizing the number of recognition units while maintaining full display functionality.
Solution Approach 2:
The patent transitions from a two-dimensional display surface to a three-dimensional integration by placing infrared emitting and receiving units at different positions within the pixel sub-regions. This spatial arrangement in multiple dimensions allows more recognition units to be accommodated without reducing the effective display area.
3Length of stationary object
If infrared units are integrated into the display panel, then bezel width is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent applies different functional qualities to different regions of the display panel. Each pixel sub-region is designed with specific combinations of sub-pixel units and infrared units according to local requirements. This localized functional assignment allows for optimized manufacturing processes in each region while achieving the overall goal of reduced bezel width.
