Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional two-dimensional touchscreen is used, then the device structure is simple, but the user interface variety and three-dimensional interaction capability are limited
Solution Approach 1:
The patent transitions from a two-dimensional touchscreen to a three-dimensional curved display system. The curved monitor creates a concave display surface, and the position input unit detects three-dimensional hand positions in space, enabling users to interact with virtual objects in a three-dimensional environment rather than being constrained to a flat surface.
Solution Approach 2:
The patent employs a curved monitor with a specific radius of curvature to create a concave display surface. This curvature provides a realistic three-dimensional image display and creates a sense of depth, allowing users to stretch their hands into the concave space for more natural air touch interactions.
2Measurement precision
If a flat touchscreen is used, then the manufacturing process is simple, but the spatial interaction and realistic three-dimensional image display are limited
Solution Approach 1:
The patent replaces traditional mechanical touch panel sensing with optical or ultrasonic sensing. The position input unit uses infrared sensors or ultrasonic sensors to detect hand positions in three-dimensional space without requiring physical contact with the display surface, thereby achieving precise three-dimensional position detection.
Solution Approach 2:
The patent introduces an intermediary sensing system between the user and the display. The position input unit acts as an intermediary that detects hand positions in the air and transmits this information to the image control unit, enabling air touch input without direct contact with the curved monitor surface.
3Ease of operation
If a curved display with air touch function is implemented, then the three-dimensional interaction capability is enhanced, but the device complexity increases
Solution Approach 1:
The patent creates a multi-functional display system where the curved monitor serves both as a visual display device and as part of a three-dimensional interaction interface. The position input unit detects various types of air touch gestures, and the image control unit processes multiple types of input signals, providing universal control capabilities for different applications.
Solution Approach 2:
The patent merges the display function and the sensing function into an integrated system. The curved monitor and the position input unit work together as a unified air touch interface, combining visual output with spatial input detection to create a cohesive three-dimensional interaction experience.
