Vehicle Interior Display Panel With Through-Hole Light Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle interior designs fail to display a clear image while maintaining design characteristics, as light transmitted through decorative panels is not effectively utilized to enhance visual clarity within the cabin.
Innovation Solution
A vehicle design featuring a display device with light-emitting bodies covered by an interior material with through holes, allowing light to pass through and create a clear image within the cabin while maintaining design aesthetics, and optionally incorporating a laminate body of thin, bendable sheet-like members for enhanced strength and conformability to the cabin's shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a decorative panel made of resin is disposed at the vehicle cabin inner side of the light-emitting member, then design characteristics of the interior are maintained, but light transmitted through the panel reaches the vehicle cabin interior causing unclear image display
Solution Approach 1:
The invention extracts the light transmission function from the decorative panel by introducing a separate interior material with through holes. This allows the decorative panel to maintain its design characteristics while blocking light, and the interior material to handle light transmission for clear image display.
Solution Approach 2:
The invention introduces an intermediary interior material between the light-emitting member and the decorative panel. This intermediary component mediates the conflicting requirements by selectively transmitting light through controlled openings while allowing the decorative panel to maintain its aesthetic function.
2Strength
If the interior material is configured as a laminate body with multiple sheet-like members, then strength is improved and conformability to three-dimensional shape is enhanced, but device complexity increases
Solution Approach 1:
The invention segments the interior material into multiple thin sheet-like members that can be individually formed and then laminated together. This segmentation allows each layer to conform to complex three-dimensional shapes independently while the combined laminate provides enhanced strength.
Solution Approach 2:
The invention uses composite material construction by laminating multiple sheet-like members together. This creates a composite structure that combines the flexibility and conformability of thin sheets with the strength and rigidity of the multi-layer assembly.
3Loss of information
If through holes are configured as slits with length direction along the vehicle front-rear direction, then light flow in the front-rear direction is visually recognized continuously, but image clarity in other directions may be compromised
Solution Approach 1:
The invention applies local quality by configuring slits with specific orientation (along vehicle front-rear direction) at specific locations (instrument panel and door). This directional slit configuration optimizes visual recognition for the primary viewing direction while maintaining adequate image clarity through proper slit dimension design.
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 enables clear image display within the vehicle cabin while preserving design characteristics, improving the strength of interior materials and ensuring uninterrupted visual recognition of light flow, and providing a clear warning display when necessary.
Implementation Method 1
light emitted from the light-emitting bodies of the display device passes through the through holes of the interior material and reaches a space within the vehicle cabin
Data Source
AI summary
A vehicle includes: a display device that includes plural light-emitting bodies at a vehicle cabin inner side; and an interior material that has plural through holes penetrating in a thickness direction formed therein, and that is disposed at a vehicle cabin inner side of the display device so as to cover the display device.
