Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a flexible projection display screen is bent to improve holographic effect, then the holographic effect is enhanced, but it becomes difficult to adjust the bending angle by touching the screen
Solution Approach 1:
The patent introduces gesture recognition technology as an intermediary between the user and the flexible projection display screen. Instead of directly touching the screen to adjust the bending angle, users perform gestures in the air, and the system captures these gestures through cameras and processes them to control the screen's bending angle, thereby resolving the contradiction between enhancing holographic effect and maintaining ease of operation
Solution Approach 2:
The patent replaces the mechanical touch-based adjustment system with an optical gesture recognition system. Instead of using physical contact to adjust the bending angle, the system uses cameras to capture hand gestures, processes these gestures through image processing algorithms, and converts them into control signals for adjusting the screen's shape, thus eliminating the need for direct mechanical interaction
2Ease of operation
If gesture recognition system is added to enable non-contact adjustment, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent makes the gesture recognition system multi-functional by integrating it with the existing flexible projection display screen system. The same camera system used for gesture recognition also serves the projection display function, and the processing module handles both gesture interpretation and screen control, thereby reducing the need for separate dedicated components and minimizing the increase in device complexity
