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 3-dimensional detail of analogue instruments, and are often cost-intensive and restrictive in design due to technological and cost constraints.
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, enabling the creation of a 3D display surface using conventional 2D display technologies, which can be more flexible and cost-effective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional 2D display technologies are used, then cost-effectiveness is maintained, but the display lacks 3-dimensional detail and perceived value
Solution Approach 1:
An optical faceplate with light-guiding material is introduced as an intermediary component between the 2D display and the user. This faceplate contains optical elements (such as microlenses or light guides) that redirect light from the flat display surface to create a perceived 3D effect, allowing conventional 2D displays to achieve analogue instrument appearance without requiring expensive 3D display technology
Solution Approach 2:
The optical faceplate adds a third dimension to the light propagation path by using vertical light guidance structures within the faceplate. Light from the 2D display is redirected through the optical elements in the faceplate to create depth perception and 3D visual effects, effectively transforming a 2D display into a 3D visual experience
2Adaptability or versatility
If flexible 3D display surfaces are created using other concepts, then design flexibility is improved, but cost increases significantly
Solution Approach 1:
The optical faceplate is designed as a separate, modular component that can be independently manufactured and then integrated with various 2D display types. The faceplate contains segmented optical elements (such as arrays of microlenses or light guide structures) that can be configured in different patterns to achieve different display geometries and designs, allowing flexibility without requiring the entire display system to be custom-built
Solution Approach 2:
The optical faceplate serves multiple functions: it creates 3D visual effects, provides mechanical support, enables different display geometries (circular, rectangular, curved), and can be integrated with various 2D display technologies. This multi-functionality allows a single component design to achieve design flexibility across different applications without requiring expensive custom 3D display systems for each configuration
