Panel for a vehicle interior and ventilation arrangement for a motor vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle interior panels with lamellas often suffer from disturbing light reflections and highlights due to the reflection of light from the lamellas and support pieces, which can be distracting for drivers.
Innovation Solution
Incorporating a light absorption compartment on the side of the lamellas facing the support piece, which redirects and traps light beams, reducing their intensity and preventing reflections by allowing them to exit only minimally, thus acting as a light trap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If lamellas are arranged parallel to extend from the support piece toward the vehicle interior, then the panel provides a clean visual appearance and integrates vent outlets, but disturbing light reflections and highlights occur when light reflects off the lamellas and support piece back to observers
Solution Approach 1:
The harmful reflective surfaces are extracted and separated from the main panel structure by introducing a light absorption compartment. This compartment is positioned between the support piece and the lamellas, effectively removing the problematic reflection path from the overall panel system while preserving the external aesthetic appearance.
Solution Approach 2:
A light absorption compartment is introduced as an intermediary element between the support piece and the lamellas. This mediator absorbs stray light before it can reflect off the support piece and lamellas, preventing the harmful reflections from reaching observers while allowing the panel to maintain its desired visual appearance.
2Ease of manufacture
If the panel uses a simple structure with lamellas directly attached to the support piece, then manufacturing is simplified, but light reflections create distracting highlights
Solution Approach 1:
The light absorption compartment is nested within the existing panel structure, positioned between the support piece and the lamellas. This nesting approach integrates the light-absorbing function into the existing manufacturing process without requiring completely separate assembly steps, thus maintaining ease of manufacture while eliminating harmful reflections.
3Stability of the object's composition
If lamellas are made rigidly attached for structural stability, then the panel maintains its shape, but light reflections from the rigid surfaces create distracting highlights
Solution Approach 1:
Different parts of the panel are given different optical properties to address the reflection problem locally. The light absorption compartment is positioned specifically in the region where reflections occur (between the support piece and lamellas), while the lamellas themselves maintain their rigid structure for stability. This localized application of light absorption preserves structural integrity while eliminating harmful reflections from critical surfaces.

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 light absorption compartment effectively minimizes or eliminates distracting light reflections and highlights on the panel, enhancing the visual appeal and reducing glare for observers.

AI summary
A panel for a vehicle interior having a plurality of lamellas fastened to a support piece of the panel. At least one of the lamellas is engaged from behind in at least some sections on a side of a light absorption compartment facing away from the support piece. A ventilation arrangement for a motor vehicle is also provided.
