Trim Element Integrated Display Luminous Sheet Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle trim elements with integrated display devices require large dimensions to be comfortably visible, increasing footprint and cost, and the transition between the display area and the outer surface detracts from the appearance by being visible.
Innovation Solution
A trim element with a luminous sheet that extends beyond the display area to illuminate the peripheral area, making the transition between the display area and the trim piece invisible and allowing for a reduced display device size while maintaining sufficient visibility for passengers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display area and housing are made large to ensure comfortable visibility for passengers, then the visibility and display quality are improved, but the footprint and cost of the trim element increase
Solution Approach 1:
The patent extends the display area into the third dimension by projecting it onto the outer surface of the trim element through a transparent or translucent housing. This allows the display to appear larger and more visible without increasing the physical footprint within the trim element, as the display images are projected outward rather than requiring a larger internal display area
Solution Approach 2:
The patent uses a transparent or translucent housing (shell) that allows the display area to be seen through the outer surface of the trim element. This thin film approach enables the display to be integrated into the trim element's existing structure without requiring additional space, while maintaining good visibility for passengers
2Shape
If the display area extends in continuity with the outer surface to improve appearance, then the visual integration is improved, but the transition between display area and peripheral area remains visible which detracts from appearance
Solution Approach 1:
The patent illuminates the peripheral area surrounding the display area to match the brightness and color characteristics of the display area. This lighting approach makes the transition between the display area and peripheral area substantially invisible, creating a seamless appearance that enhances visual integration while maintaining manufacturing feasibility
Solution Approach 2:
The patent introduces an illumination device as an intermediary element that bridges the display area and peripheral area. By controlling the lighting in the peripheral area to match the display area characteristics, the illumination acts as a mediator that hides the transition boundary and creates a seamless visual appearance
3Area of moving object
If the display device is made large to provide sufficient display dimensions, then the display quality is improved, but the cost of the trim element increases
Solution Approach 1:
The patent uses a transparent or translucent housing that acts as a window or lens, allowing the display area to be projected onto the outer surface of the trim element. This copying approach enables the display to appear larger than the actual physical display device, providing sufficient display dimensions without requiring a proportionally larger and more expensive display hardware
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 provides a visually integrated display with reduced space and cost requirements, enhancing the appearance by making the transition between the display and peripheral areas invisible, thus creating a seamless outer surface while maintaining sufficient display dimensions.
Implementation Method 1
the illumination device comprises a luminous sheet extending at least facing the display area and the peripheral area of the edge piece
Data Source
AI summary
A trim element having a display area defined by a display device, and an edge piece that includes a peripheral area extending around at least part of the display area, the peripheral area being at least partly translucent, the display area and the peripheral area forming at least a part of an outer surface of the trim element. The trim element further includes an illumination device arranged to illuminate the display device to display images on the display area. The illumination device has a luminous sheet extending at least facing the display area and the peripheral area of the edge piece.
