Vehicle Decorative Element Openings for Wrinkle-Free Lamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional decorative elements for vehicle interiors face challenges in achieving high lamination quality and stability, especially with delicate functional openings, leading to inefficiencies and complex designs being omitted due to warping and wrinkling issues during the lamination process.
Innovation Solution
A method for manufacturing decorative elements with functional openings involves creating a composite of a decoration blank and an application material layer, using adhesive to bond them, and then processing this composite with a cutting machine to form precise functional openings, which can be filled with filler materials for illumination or sound applications, ensuring stability and high lamination quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional decorative elements with delicate functional openings are laminated onto a carrier structure, then the decorative element can be applied to the vehicle interior, but the decorative element forms wrinkles or warping during lamination, resulting in poor lamination quality
Solution Approach 1:
The decorative element is pre-assembled with all functional openings and bridges in their correct positions before lamination. This preliminary assembly ensures that delicate bridges are properly positioned and supported before the lamination process begins, preventing warping and wrinkles during application to the carrier structure.
Solution Approach 2:
The invention uses a composite structure where decorative elements with delicate bridges are combined with a supportive carrier structure. The carrier structure provides mechanical support to the delicate bridges during lamination and service, enabling high lamination quality without requiring excessive alignment effort.
2Reliability
If decorative elements are aligned and laminated with great effort to achieve high lamination quality, then lamination quality improves, but production time increases significantly
Solution Approach 1:
By pre-assembling decorative elements with functional openings and bridges before lamination, the alignment process is simplified and standardized. This preliminary preparation enables faster, more consistent lamination operations in serial production, improving productivity while maintaining high lamination quality.
Solution Approach 2:
The invention replaces manual alignment and positioning operations with automated lamination processes. The pre-assembled decorative elements can be applied using automated systems, reducing production time and increasing efficiency while maintaining consistent quality standards.
3Adaptability or versatility
If delicate bridges between functional openings are used to create complex patterns, then design complexity increases, but the bridges are difficult to align and laminate without warping
Solution Approach 1:
The carrier structure acts as a composite support that provides mechanical stability to delicate bridges between functional openings. This composite construction enables complex patterns with fine bridges to be manufactured and laminated with high precision, as the carrier structure prevents warping and maintains alignment during the lamination process.

AI summary
A method for manufacturing a decorative element, includes a functional opening, for a motor vehicle, as well as a decorative element. A decoration blank that includes a visible side and an adhesive side, and an application material layer that includes an adhesive side, and a lamination side are provided. A composite made of the decoration blank and the application material layer is produced by the adhesive side of the decoration blank and the adhesive side of the application material layer being adhered to each other by an adhesive layer. The decoration blank is cut through along a functional opening contour by a cutting element of a cutting machine, and a waste piece is removed, forming the functional opening. The functional opening is filled with a filler material that reacts into a cured state. The opening is at least partially translucent, at least partially transparent, completely transparent, or light impermeable.
