Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional displays with light-resistant materials and invisible holes are used, then high resolution display is achieved, but the display lacks enhanced functionalities for receiving and processing external information
Solution Approach 1:
The display device integrates multiple functions into a single system: it can display images through invisible holes, scan objects using optical sensors, perform biometric identification, and receive external optical signals. The light-resistant material structure with integrated sensors enables the display to serve both as an output device and an input device, achieving multi-functionality without compromising display quality.
Solution Approach 2:
The patent combines the display function with sensing functions by integrating optical sensors and light sources directly into the display panel structure. The sensing elements are positioned within the light-resistant material, merging the display and sensing capabilities into a unified device that can simultaneously display information and process external optical signals.
2Adaptability or versatility
If optical sensors and light sources are integrated into the display panel, then scanning and biometric identification capabilities are enabled, but device complexity increases
Solution Approach 1:
The optical sensors and light sources are nested within the light-resistant material structure of the display panel. The sensing elements are positioned in the spaces between the invisible holes or integrated into the base layer, creating a compact nested arrangement where multiple components occupy the same spatial envelope without significantly increasing the overall device footprint.
Solution Approach 2:
The display panel features local variations in structure: light sources and optical sensors are positioned specifically at certain locations (within or below the base layer), while other areas maintain the light-resistant material structure for display purposes. This localized integration allows sensing functions to be added only where needed, minimizing overall complexity.
3Measurement precision
If multiple light sources and sensors are positioned within optical paths, then accurate scanning and high contrast are achieved, but power consumption increases
Solution Approach 1:
The optical sensors and light sources operate in periodic or pulsed modes rather than continuously. During scanning operations, light sources emit light in sequences corresponding to different colors or wavelengths, and sensors activate periodically to detect reflected light. This periodic operation maintains measurement precision while significantly reducing average power consumption compared to continuous operation.
Solution Approach 2:
The display maintains its display function continuously while sensing operations are performed intermittently. The light-resistant material structure allows the display to operate independently of the sensing function, enabling the useful display action to continue without interruption while power-consuming sensing operations are performed only when needed for scanning or identification.
