Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only touch control technology is used, then short-range interaction is achieved, but remote interaction capability is lost
Solution Approach 1:
The patent combines three distinct functional modules (display module, light-sensing module, and touch control module) into a single integrated display device. The light-sensing units are positioned between pixel units, and antenna loops are formed using data lines and power lines, merging multiple functions into one unified structure that supports both remote and short-range interaction modes.
Solution Approach 2:
The display device is designed to perform multiple interaction functions: the display module provides visual output, the light-sensing module enables remote gesture recognition through photoelectric sensing, and the touch control module provides capacitive touch input. This multi-functional integration allows a single device to handle diverse interaction scenarios without requiring separate components.
2Adaptability or versatility
If light-sensing module is added for remote sensing, then remote interaction is enabled, but device structure becomes more complex
Solution Approach 1:
The light-sensing module is integrated within the display structure by positioning light-sensing units between pixel units of the display module. This shared structural space reduces overall device complexity while enabling remote sensing functionality. The same substrate and layer structure support both display and light-sensing functions.
Solution Approach 2:
The data lines and power lines serving the display module are repurposed to form antenna loops for the light-sensing module. This eliminates the need for separate antenna structures, reducing device complexity while enabling remote gesture recognition through photoelectric sensing and signal transmission.
3Ease of operation
If touch control module is integrated, then short-range touch control is achieved, but remote control capability is not provided
Solution Approach 1:
The touch control module with antenna loops is integrated alongside the light-sensing module and display module. The antenna loops formed by data lines and power lines enable capacitive touch sensing for short-range interaction, while the light-sensing units enable remote gesture recognition, combining both interaction ranges in one unified system.
Solution Approach 2:
The display device provides multiple interaction modes: capacitive touch control for short-range direct contact input, and photoelectric sensing for remote gesture recognition. This multi-functional design allows the same device to adapt to different interaction scenarios, enhancing versatility while maintaining ease of operation for each mode.
