Solution Overview

Problem

Current methods for producing decorative elements with functional openings, especially in the automotive sector, face challenges in precise alignment and efficient lamination due to the complexity and flexibility of the elements, leading to issues like wrinkling and warping, which increases production time and reduces reproducibility.

Innovation Solution

A method involving the creation of decorative cut-outs with through holes, combined with a functional coating that can be temporarily or permanently attached, filled with a material to form functional openings, and laminated onto a carrier structure using a soft or hard lamination process, ensuring precise alignment and stability without distortion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If flexible decorative cut-outs are used to create complex patterns, then design versatility is improved, but alignment precision deteriorates

Engineering Contradiction:
Improvedesign versatilityVSAvoidalignment precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Alignment marks are printed on the decorative cut-outs before lamination, and the carrier structure is pre-heated to the bonding temperature. These preliminary actions enable precise alignment to be achieved during the lamination process by providing visual references and ensuring the carrier is at the correct temperature for bonding, thereby resolving the contradiction between design versatility and alignment precision.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If decorative elements with openings are laminated onto carrier structures, then functional openings are achieved, but lamination quality deteriorates due to wrinkling and warping

Engineering Contradiction:
Improvefunctional openingsVSAvoidlamination quality
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The lamination process uses controlled temperature and pressure parameters applied uniformly across the decorative element. The carrier structure is heated to a specific bonding temperature range, and pressure is applied through the roller in a controlled manner. These parameter changes enable successful lamination of decorative elements with openings by preventing local overheating and uneven bonding that cause wrinkling and warping, thus resolving the contradiction between achieving functional openings and maintaining lamination quality.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If manual positioning and fixing of flexible decorative elements is used, then lamination is achieved, but production efficiency deteriorates

Engineering Contradiction:
Improvelamination processVSAvoidproduction efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The manual mechanical positioning and fixing process is replaced by an automated lamination system. The decorative cut-outs are fed through the lamination unit, where they are automatically heated, pressed, and bonded to the carrier structure in a continuous process. This substitution of manual mechanical operations with an automated thermal-mechanical system dramatically improves production efficiency while maintaining ease of manufacture, resolving the contradiction between these two parameters.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Manufacturing precision

If precise alignment of decorative cut-outs is achieved, then manufacturing precision is improved, but production time increases

Engineering Contradiction:
Improvealignment precisionVSAvoidproduction time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The lamination process is designed as a continuous operation where decorative cut-outs are fed through the lamination unit without interruption. Alignment marks are printed in advance, and the continuous feeding and lamination process maintains constant motion, eliminating idle time for manual realignment. This continuity of useful action achieves precise alignment through the alignment marks while maintaining high production speed, resolving the contradiction between manufacturing precision and production time.

Inventive Principle:
Principle #20Continuity of useful action
