Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single gesture detection unit is used, then the device complexity is reduced, but the versatility of gesture commands is limited
Solution Approach 1:
The gesture detection system is divided into multiple independent detection units, each capable of detecting specific gesture types. This segmentation allows the system to handle diverse gestures through modular components, improving versatility while keeping individual unit complexity manageable.
Solution Approach 2:
Each gesture detection unit is designed with multi-functional capability to detect various types of gestures (touch, hover, swipe, pinch, etc.). This universal design allows a single unit to perform multiple detection functions, enhancing system versatility without proportionally increasing complexity.
2Adaptability or versatility
If multiple gesture detection units with different sensible ranges are used, then the coverage of detectable gestures is improved, but the device complexity increases
Solution Approach 1:
The system extends gesture detection into multiple spatial dimensions by deploying detection units with different sensible ranges (close-range and far-range). This dimensional approach allows comprehensive coverage of various gesture types by detecting hand positions and movements from different spatial perspectives.
Solution Approach 2:
The processing unit acts as an intermediary that receives signals from multiple gesture detection units with different sensible ranges. It integrates and coordinates the data from these units, managing the complexity of multiple sensors while enabling comprehensive gesture detection coverage.
3Adaptability or versatility
If conventional input devices like mice are used, then the ease of operation is maintained, but the adaptability to different interaction styles is limited
Solution Approach 1:
The input system transitions from static input methods (keyboard, mouse) to dynamic gesture-based input. The system adapts to different interaction styles by detecting various hand gestures (touch, hover, swipe, pinch) and converting them into corresponding commands, providing both adaptability and ease of operation through natural motion.
Solution Approach 2:
The patent replaces traditional mechanical input devices (mouse, keyboard) with an optical gesture detection system. This substitution eliminates the need for physical contact with input devices, allowing users to interact through natural hand gestures in the air, thereby improving adaptability to different interaction styles while maintaining ease of operation.
