Surface Covering Seam Structure With Edge Strip Core Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle interior construction, existing laminating methods for decorative elements on support structures face challenges in achieving reliable, reproducible, and visually appealing seam alignment, particularly with the membrane laminating process which can damage the laminating medium due to permanent pivoting of the seam blade.
Innovation Solution
A multiple-part surface covering system where two individual parts are sewn together with a connecting seam, featuring an edge strip core between the cover and seam overhang, providing secure fixation to the support structure while allowing for a compact and visually appealing design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a permanent pivoted-in seam blade is used in press laminating to achieve reliable seam alignment, then manufacturing precision is improved, but device complexity increases and the laminating medium (gel cloth) is damaged
Solution Approach 1:
The seam blade is divided into a movable segment that can be pivoted into position only when needed, rather than being permanently fixed. This allows the seam blade to be introduced temporarily during the laminating process to ensure precise seam alignment, then removed afterward to avoid damaging the gel cloth laminating medium.
Solution Approach 2:
The seam blade is designed with dynamic movement capability, allowing it to be pivoted into and out of the working position during the laminating process. This dynamic positioning enables precise seam alignment when required while preventing damage to the gel cloth when the blade is not in use, resolving the contradiction between precision and device complexity/damage.
2Reliability
If membrane laminating is used to avoid damage to the laminating medium, then reliability is improved, but manufacturing precision of seam alignment deteriorates due to difficulty in pivoting the seam blade
Solution Approach 1:
The seam blade is pre-positioned or pre-aligned in a ready state before the actual laminating operation begins. This preliminary positioning ensures that when the blade is pivoted into place during membrane laminating, the seam alignment is already optimized, achieving both protection of the gel cloth and precise seam alignment without the difficulties of pivoting during the process.
3Adaptability or versatility
If multiple surface covering individual parts are sewn together with a connecting seam, then adaptability is improved, but device complexity increases due to the need for additional components like edge strip core and cover
Solution Approach 1:
The edge strip core, edge strip cover, and connecting seam components are merged into an integrated assembly that works together as a unified system. The edge strip core provides structural support and fixation, while the cover protects and aestheticizes the seam, and the connecting seam joins multiple surface covering parts. This merging allows customizable surface coverings to be assembled from modular components without requiring separate complex mechanisms for each function.

AI summary
A multiple-part surface covering for the cladding of support structures includes at least two surface covering parts, respective portion of a first and second surface covering parts, and a cover. The at least two surface covering parts are sewn to one another by way of a connecting seam. The respective portion of a first surface covering part and a respective portion of a second surface covering part form a seam overhang. The cover is sewn to the two surface covering parts by way of the connecting seam and covers the seam overhang. An edge strip core is arranged between the cover and the seam overhang.
