Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional touch screen technology is used with physical contact input, then the device can perform basic input operations, but the interaction method lacks versatility and intuitiveness for 3D content display
Solution Approach 1:
The patent extends the input space from 2D touch screen surface to 3D space above the screen by detecting hovering objects and their movement trajectories. This allows users to interact with 3D content by moving objects in three-dimensional space, providing more intuitive and versatile interaction methods while maintaining ease of operation through natural hand gestures.
2Adaptability or versatility
If the space above the touch screen is utilized for input detection, then interaction versatility is improved, but the detection complexity increases
Solution Approach 1:
The patent makes the touch screen serve multiple functions: it acts as both a display device and a proximity sensor for detecting hovering objects. By utilizing the existing capacitive properties of the touch screen for dual purposes, the system achieves versatile input detection without adding separate complex detection hardware, thus improving input diversity while controlling device complexity.
3Ease of operation
If proximity detection is implemented to detect hovering objects, then contactless interaction is enabled, but the detection precision requirements increase
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors the position and movement of hovering objects, providing visual feedback on the display to confirm detection accuracy. This feedback loop allows the system to adjust detection parameters and maintain high precision in identifying hovering objects and their trajectories without requiring overly complex detection hardware.
