Translucent Leather Material for Touch Display Vehicle Dashboards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional synthetic leather materials for vehicle dashboards interfere with image visibility and touch-control characteristics, as they lack transparency and shielding properties.
Innovation Solution
A leather material comprising a foam layer and a fabric layer, where the foam layer provides a leather feel and the fabric layer is color-matched and embossed to present a leather pattern, using base materials like polyvinyl chloride (PVC), polyurethane (PU), or polyolefin (PO), with visible light transmittance between 40% and 70% and resistivity of not less than 1010 Ωcm, allowing image visibility and shielding when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional synthetic leather is attached to the vehicle dashboard, then a leather appearance and feel are provided, but image visibility through the dashboard and touch-control characteristics are affected
Solution Approach 1:
The leather material is divided into multiple functional layers: a foam layer for providing leather feel and light transmission, and a fabric layer for providing leather pattern and appearance. This segmentation allows each layer to optimize its specific function while maintaining overall performance.
Solution Approach 2:
The patent uses composite materials consisting of foam and fabric layers with specific base materials (PVC, PU, or PO) to achieve both leather appearance and desired optical/electrical properties. The composite structure enables simultaneous achievement of aesthetic and functional requirements.
2Object-affected harmful factors
If synthetic leather with shielding property is used, then privacy protection is improved, but image display visibility is reduced
Solution Approach 1:
The leather material's shielding property is made dynamic through the dashboard's display control: when the display is active, light passes through the foam layer to show images; when inactive, the fabric layer provides shielding. This dynamic behavior resolves the contradiction between shielding and visibility.
Solution Approach 2:
Different regions of the leather material have different properties: the foam layer has high light transmittance for display areas, while the fabric layer has shielding properties for privacy protection. This local differentiation allows simultaneous achievement of both functions in different zones.
3Ease of operation
If the foam layer thickness is increased to provide better leather feel, then comfort is improved, but light transmittance decreases
Solution Approach 1:
The patent optimizes the foam layer thickness within a specific range (50-1000 μm) to balance leather feel and light transmittance. By controlling the foaming ratio (105%-130%) and using appropriate base materials, the foam layer provides sufficient cushioning while maintaining adequate transparency for display visibility.
