Vehicle Trim Display Screen Optical Layer Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle trim solutions fail to combine high perceived quality with ease and economy of manufacture, particularly in incorporating display screens in a way that maintains image sharpness and reduces visibility of the screen when not in use.
Innovation Solution
A vehicle trim design featuring a support, a display screen, and a covering with an optical layer applied directly over the screen, forming a lens to ensure image sharpness and using a translucent aspect layer to reduce visibility, combined with manufacturing methods like overmolding and spraying to integrate the optical and aspect layers effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display screen is incorporated into vehicle trim, then functionality and user experience are improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent merges the display screen integration into the vehicle trim by applying the optical layer directly over the screen with no empty space between them, combining multiple functions (display, optical enhancement, sealing) into a single integrated structure that simplifies manufacturing
Solution Approach 2:
The optical layer serves multiple functions simultaneously: it acts as an optical element to enhance image quality, a sealing element to protect the screen, and an integral part of the trim structure, thereby reducing the need for separate components and simplifying manufacturing
2Reliability
If a covering is applied over the screen, then screen protection and aesthetic quality are improved, but light transmission and image visibility are reduced
Solution Approach 1:
The patent optimizes the optical properties of the covering by carefully selecting materials and adjusting parameters such as thickness and refractive index to achieve the desired balance between protection and light transmission, ensuring images remain visible while the screen is protected
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 achieves a high-quality, economical vehicle trim with sharp image display and reduced screen visibility when not in use, enhancing user experience while simplifying manufacturing processes.
Implementation Method 1
the optical layer forms a lens configured so that an image generated by the screen is sharp on the front face of the covering
Implementation Method 2
the optical layer forms a lens configured so that an image generated by the screen is sharp on the front face of the covering
Implementation Method 3
the aspect layer has a light transmission rate of between 35% and 45%

AI summary
A vehicle trim includes a support, a display screen fixed on the support, and a covering that covers the screen, the covering having a visible front face and a back face turned toward the screen. An image generated by the screen is visible on the front face of the covering. The covering has an optical layer applied on the screen with no empty space between the optical layer and the screen.
