Solution Overview

Problem

Conventional paneling components for passenger transport vehicles face challenges in edge stability and weight reduction, leading to potential damage and increased production complexity due to the lack of sufficient edge rigidity and the need for additional decorative layer application steps.

Innovation Solution

A paneling component with folded sections and predetermined buckling points, where the folded sections are designed to increase edge stability and allow for a decorative layer to be applied before forming, ensuring the layer is not visible from the interior and reducing the risk of damage during operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If the paneling component is made with very low surface weight hybrid lightweight components, then weight is reduced, but edge stability deteriorates

Engineering Contradiction:

Improvesurface weightVSAvoidedge stability

Core Design Contradiction:

Weight of moving objectVSStability of the object's composition

Solution Approach 1:

The paneling component is divided into a face section and an edge section with different structural characteristics. The edge section includes folded sections that create multiple layers, providing enhanced stability without increasing the overall surface weight of the component.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The edge section is extended in the thickness dimension through folded sections, transforming a two-dimensional flat structure into a three-dimensional multi-layer structure. This dimensional change provides structural stability at the edges while maintaining low surface weight.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of manufacture

If the decorative layer is applied only on the interior-facing side, then production is simplified, but visual appearance deteriorates when the separating surface is visible

Engineering Contradiction:

Improveproduction complexityVSAvoidvisual appearance

Core Design Contradiction:

Ease of manufactureVSShape

Solution Approach 1:

The decorative layer is applied to the entire calibrated mat before forming, including areas that will become folded sections. This preliminary application ensures that when the folded sections are created, the decorative layer is already in place and will be visible on the exterior side, eliminating the need for secondary decoration operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The folded sections create curved or angled surfaces that redirect light and visual perception. By applying the decorative layer before folding, the layer conforms to these curved surfaces, making the decorative pattern visible and aesthetically pleasing on the exterior side of the component.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Adaptability or versatility

If the decorative layer has different thermal expansion coefficient than the paneling component, then material selection flexibility is improved, but dimensional stability deteriorates after aging

Engineering Contradiction:

Improvematerial selectionVSAvoiddimensional stability

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The paneling component is segmented into the face section and edge section with folded sections. The decorative layer is applied to both sections, and the folded structure provides mechanical constraint that limits the visible impact of differential thermal expansion, maintaining dimensional stability despite material flexibility.

Inventive Principle:

Principle #1Segmentation

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 enhances edge stability, reduces weight, simplifies production, and maintains a visually appealing interior design by integrating the decorative layer during the manufacturing process without additional steps, thus addressing the issues of edge rigidity and weight reduction.

Implementation Method 1

Before the mat can be further processed, it must first be calibrated, for example to remove any air it contains. For this purpose, the mat is heated and pressed.

Methodology Applied

Scientific EffectHeating: Heating

Implementation Method 2

The molding tool can press the decorative layer with the calibrated mat and create a firm connection.

Methodology Applied

Scientific EffectCompression: Compression

Implementation Method 3

the decorative layer has a different coefficient of thermal expansion or shrinkage than the lining component. The situation can therefore arise in which the decorative layer contracts, in particular after a certain aging of the paneling component

Methodology Applied

Scientific EffectThermal contraction: Thermal Contraction
