Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display devices only have basic display functions, then device complexity is low, but functionality and user interaction capability are limited
Solution Approach 1:
The patent combines multiple functional modules (light source, image sensor, photodetector, processing circuit) into an integrated array substrate that simultaneously performs display and three-dimensional imaging functions. This merging approach enables the display device to acquire three-dimensional imaging information and perform gesture recognition while maintaining a relatively compact structure, thus resolving the contradiction between enhanced functionality and device complexity.
Solution Approach 2:
The array substrate is designed as a multi-functional device that can both display images and perform three-dimensional imaging. The light source, image sensor, and photodetector work together to enable the same device to serve multiple purposes: traditional display function and advanced three-dimensional imaging/gesture recognition function, thereby improving adaptability without proportionally increasing complexity.
2Adaptability or versatility
If three-dimensional imaging components are added to display devices, then gesture recognition capability is improved, but device structure becomes more complex
Solution Approach 1:
The patent integrates the three-dimensional imaging components (light source, image sensor, photodetector) directly into the array substrate structure, merging them with the display device rather than adding them as separate external components. This integration approach enables gesture recognition capability while minimizing the increase in overall device structural complexity.
3Adaptability or versatility
If multiple functional modules are integrated in the array substrate, then three-dimensional imaging function is achieved, but manufacturing process becomes more difficult
Solution Approach 1:
The patent merges the three-dimensional imaging function with the existing array substrate manufacturing process. By integrating the light source, image sensor, and photodetector into the same substrate that already exists in display device production, the patent leverages existing manufacturing capabilities and processes, thereby achieving three-dimensional imaging function while minimizing the increase in manufacturing difficulty.
