Polyurethane Vehicle Display Coating for Scratch-Resistant Styling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies for vehicles, particularly those using ceramic materials, face challenges such as high development and manufacturing costs, low stability, and limited design freedom due to the need for expensive and time-consuming production methods, as well as unsatisfactory adhesion and scratch resistance.
Innovation Solution
A polyurethane-based display system that includes a decorative element with a recessed printed film coated with a polyurethane layer, providing mechanical stability and scratch resistance, and allowing for various design options without the need for adhesives, using a method that decouples the processing of the decorative element from other components and employs polyurethane layers for fixation and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If ceramic materials are used for display elements in vehicles, then a pleasant feel and high-quality appearance are achieved, but the components become expensive
Solution Approach 1:
The patent combines ceramic materials with polyurethane-based compounds to create a composite display element. The ceramic provides the pleasant feel and high-quality appearance, while the polyurethane-based compound offers cost advantages and additional functional benefits such as flexibility and durability.
2Ease of manufacture
If plastic symbols are introduced into ceramic surfaces by injection molding, then manufacturing costs are reduced, but the visual value is compromised because ceramic bars remain visible
Solution Approach 1:
The patent uses a polyurethane-based compound that can be molded to create a seamless integration with ceramic surfaces. This flexible material allows for complete coverage and customization of display elements, eliminating visible ceramic bars while maintaining aesthetic quality.
3Ease of manufacture
If symbol-shaped recesses are created in ceramic surfaces, then plastic symbols can be embedded, but ceramic material waste increases significantly
Solution Approach 1:
The patent merges the ceramic substrate with the polyurethane-based display elements in a unified structure. By eliminating the need for separate symbol-shaped recesses and using a moldable compound, the process reduces ceramic material waste while achieving the same embedding function.
4Shape
If additional grinding process steps are applied to ceramic surfaces with sharp edges, then surface quality is improved, but tool costs increase
Solution Approach 1:
The polyurethane-based compound inherently provides a smooth, flexible surface that can be molded directly without requiring additional grinding steps. This eliminates the need for expensive grinding tools while achieving high surface quality.
5Reliability
If plate-shaped inlays are used to replace ceramic bars, then adhesion stability improves, but production becomes more costly and time-consuming
Solution Approach 1:
The patent creates a composite structure where the polyurethane-based compound is integrally molded with the ceramic substrate, providing strong adhesion stability throughout the entire display element. This unified approach eliminates the need for separate plate-shaped inlays and their associated high production costs.
6Object-affected harmful factors
If films printed with symbols are glued to ceramic surfaces, then scratch protection is achieved, but expensive special adhesives are required and design flexibility is limited
Solution Approach 1:
The polyurethane-based compound serves as both the protective layer and the display element itself. This flexible, moldable material provides inherent scratch protection and design flexibility without requiring expensive special adhesives, as the compound is integrally formed with the ceramic substrate.
