Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a floating image touch-control panel is used to avoid physical contact, then hygiene is improved, but user feedback and interaction confirmation deteriorate
Solution Approach 1:
The patent implements feedback by detecting touch gestures on the floating image and generating corresponding feedback images that display the detected gesture type. This allows users to visually confirm their touch actions without physical contact, resolving the contradiction between hygiene and user feedback.
Solution Approach 2:
The patent uses color changes in the feedback images to indicate different touch gesture types and states. The floating image and feedback images utilize color variations to provide visual information about user interactions, maintaining engagement without physical contact.
2Loss of information
If conventional mechanical buttons are used, then user feedback is clear, but hygiene and contactless operation deteriorate
Solution Approach 1:
The patent replaces mechanical buttons with a touch-sensitive floating image system. The mechanical contact interface is substituted with optical display and gesture detection technology, eliminating physical contact while maintaining clear user feedback through visual feedback images.
Solution Approach 2:
The patent creates visual copies of button functions through floating images and feedback images. Instead of physical buttons, the system uses displayed image representations that replicate button functionality, providing clear feedback without mechanical contact surfaces.
3Device complexity
If a single floating image is displayed, then device complexity is low, but adaptability and user experience deteriorate
Solution Approach 1:
The patent segments the floating image into multiple controllable regions corresponding to different functional buttons. Each region can be independently detected and responded to, allowing multiple functions within a single visual element without increasing overall system complexity.
Solution Approach 2:
The patent implements dynamic behavior where the floating image and feedback images change based on detected gestures. The system adapts its visual output in real-time based on user interaction, providing versatility while maintaining a relatively simple image generation structure.
