Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cladding parts in vehicle interiors face limitations due to material choices and production methods, which restrict their aesthetic and functional applications, particularly in maintaining a high-quality visual appearance and handling structural elements like edges and light transmission.
Innovation Solution
A cladding part featuring a carrier part with a surface covering made of intrinsically stiff knitted-fabric material, which includes a visible layer and a hidden, translucent stiff layer, allowing for edgeless designs and integrated light effects through strategically placed apertures and light sources, and can be adhesively bonded to the carrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional flexible materials are used for surface covering, then ease of manufacture is improved, but visual quality deteriorates due to edge reproduction and deformation
Solution Approach 1:
The patent changes the physical parameter of the surface covering material from flexible to intrinsically stiff, transforming the material properties to eliminate deformation and edge reproduction while maintaining manufacturing feasibility through adhesive bonding processes
Solution Approach 2:
The patent creates a composite structure by bonding the intrinsically stiff knitted-fabric material to a carrier part, combining the aesthetic and structural benefits of stiff material with the manufacturing advantages of composite construction
2Manufacturing precision
If intrinsically stiff knitted-fabric material is used for surface covering, then visual quality is improved by eliminating edge reproduction, but device complexity increases due to material and production requirements
Solution Approach 1:
The intrinsically stiff knitted-fabric material serves multiple functions simultaneously: it provides the visible decorative surface, maintains structural stability without edge reproduction, and enables light transmission when combined with apertures, reducing the need for separate components
3Strength
If the surface covering is made opaque for structural integrity, then strength is improved, but light transmission capability deteriorates
Solution Approach 1:
The patent applies different optical properties to different regions: the intrinsically stiff knitted-fabric material itself remains opaque for structural integrity, while strategic apertures create localized transparent regions that allow light transmission, achieving both strength and illumination requirements in different areas
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 high-quality, edgeless surface with integrated light effects, enhancing the visual appeal and functionality of cladding parts in vehicle interiors while maintaining structural integrity, suitable for various applications including vehicle interiors, transportation, and furniture.
Implementation Method 1
the surface covering does not deform in regions in which it is not supported by the carrier part, even under the action of gravitational force
Implementation Method 2
The intrinsically stiff layer may have a translucent design. This offers the advantage that light striking the intrinsically stiff layer can pass through the layer
Implementation Method 3
The heat needed to activate the adhesive is introduced into the adhesive joint through the skin via a hot press die of the press laminating tool by way of contact heat
Implementation Method 4
by means of IR radiation. This activates the adhesive during the laminating method
