Solution Overview
Problem
Existing vehicle user interfaces with two-dimensional touchscreens face challenges in user-friendly interaction, high manufacturing costs, and optical losses due to multiple layers, which affect image quality and distract drivers with lack of haptic feedback.
Innovation Solution
A user interface integrating a two-dimensional display with an optical faceplate and optic light guide material between the contact surface and a three-dimensional display surface, reducing the number of layers and providing a physical affordance while improving light transmission and appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a two-dimensional touchscreen display is used to provide multiple functions, then the functionality is improved, but the ease of operation deteriorates due to lack of haptic feedback and increased driver distraction
Solution Approach 1:
The patent merges a physical button with a touchscreen display into a hybrid component. The physical button provides tactile feedback and familiar interaction, while the touchscreen overlay adds digital functionality. This combination allows the system to maintain the ease of physical buttons while gaining the versatility of touchscreen capabilities.
Solution Approach 2:
The patent transitions from a purely two-dimensional touchscreen interface to a three-dimensional hybrid interface by adding a physical button element. This dimensional addition provides haptic feedback and physical affordance, improving ease of operation while maintaining touchscreen versatility through the overlay layer.
2Adaptability or versatility
If multiple layers are used in the touchscreen display, then the functionality and touch sensitivity are improved, but the light transmission deteriorates causing image quality loss
Solution Approach 1:
The patent extracts and eliminates unnecessary intermediate layers from the touchscreen structure. By removing redundant adhesive layers and optimizing the layer stack, the design maintains touch functionality while reducing optical boundaries that cause reflection and refraction losses, thereby improving light transmission and image quality.
3Strength
If a bezel is used to conceal the display border, then the structural integrity is improved, but the appearance deteriorates due to visible black mask and reduced display area
Solution Approach 1:
The patent uses a thin, flexible faceplate that can be shaped to follow the contour of the physical button while maintaining structural integrity. This thin film approach allows the display to extend closer to the edges without requiring a thick bezel, improving appearance while maintaining strength through the button's structural support.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances user interaction with reduced optical losses, improved image quality, and cost-effectiveness, offering a seamless and visually appealing interface that minimizes driver distraction by combining tactile feedback with visual information.
Implementation Method 1
an optical faceplate comprising a contact surface, a three-dimensional display surface for displaying information, and an optic light guide material provided between the contact surface and the three-dimensional display surface
Implementation Method 2
Between any two layers, an optical boundary exists at which reflection and/or refraction can occur. This can cause light transmission losses
