Optical Faceplate for 3D Vehicle Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies in vehicles are limited to two-dimensional flat surfaces, lacking the perceived value and design flexibility of analog instruments, and are often cost-intensive, making it difficult to create immersive user interfaces for modern vehicle systems.
Innovation Solution
An optical faceplate is used with a two-dimensional display, featuring a contact surface and a three-dimensional display surface connected by an optic light guide material, allowing for the creation of a 3D display surface using conventional 2D display technologies, enhancing both optical and tactile appearance and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional 2D display technologies are used, then cost constraints are satisfied and technological simplicity is maintained, but the perceived value and 3-dimensional detail are insufficient
Solution Approach 1:
The patent introduces an optical faceplate as an intermediary component between the 2D display and the user. This faceplate contains light guide elements that redirect light from the flat display surface to create the perception of depth and 3D detail, allowing conventional 2D displays to achieve the perceived value of 3D displays without the complexity of true 3D display technology
Solution Approach 2:
The optical faceplate adds a third dimension to the light propagation path by using light guide elements that redirect light at various angles. This creates the illusion of depth and 3D detail on an otherwise 2D display surface, effectively adding a perceptual dimension without changing the physical display structure
2Adaptability or versatility
If flexible displays curved across one axis are used, then design flexibility is improved, but cost increases and design limitations remain
Solution Approach 1:
The optical faceplate is divided into multiple segments or zones, each with different light guide patterns and optical properties. This segmentation allows different portions of the display to have different curvatures and design characteristics, enabling complex 3D surface designs while using standard 2D display panels and keeping manufacturing costs manageable
Solution Approach 2:
The optical faceplate uses composite materials combining different optical indices and light guide properties in various layers and zones. This allows the creation of complex 3D surface geometries with controlled light distribution, achieving design flexibility comparable to curved flexible displays without the associated cost and manufacturing complexity
3Shape
If 3D display surfaces are created using optical faceplates, then design flexibility and user perception are improved, but the complexity of the display system increases
Solution Approach 1:
The optical faceplate is designed as a universal component that can be applied to various 2D display types and sizes. It provides multiple functions including light redistribution, 3D surface creation, and viewing angle expansion, thereby managing complexity through a single multi-functional element rather than multiple specialized components
