Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch-control panels with floating images lack user feedback, making it difficult for users to confirm if they have successfully interacted with the panel.
Innovation Solution
A floating image generation device comprising a light source, shading unit, and image generation unit that changes light transmissivity states to generate different floating images, combined with a sensing module to provide tactile feedback through touch-control motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a touch-control panel with floating image 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 (such as hovering or approaching movements) and responding by changing the floating image content or providing visual cues. This allows the system to communicate with the user without physical contact, maintaining hygiene while providing interaction confirmation.
Solution Approach 2:
The floating image serves as an intermediary between the user and the control function. It provides visual information about available functions and confirms user intent through image changes, enabling interaction without direct physical contact with buttons or panels.
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 floating image display system that detects gestures and provides visual feedback. This substitution eliminates physical contact surfaces while maintaining clear user feedback through image changes and visual cues.
Solution Approach 2:
The floating image changes its appearance (such as color, brightness, or content) in response to detected gestures, providing visual feedback to the user. This dynamic visual response replaces the tactile feedback of mechanical buttons while maintaining contactless operation.
3Device complexity
If a static floating image is displayed, then device complexity is low, but adaptability and user experience deteriorate
Solution Approach 1:
The patent implements dynamic floating images that change based on detected gestures, selected functions, or system state. This allows the same device to display different images for different purposes without requiring multiple physical buttons or complex mechanical switching mechanisms.
Solution Approach 2:
A single floating image display system serves multiple functions by changing its content dynamically. It can display different control options, provide feedback for various gestures, and adapt to different operational modes, replacing what would traditionally require multiple specialized components.
