Pleated Vehicle Interior Covering for Complex Surface Lamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating a pleated appearance on vehicle interior surfaces fail to securely attach flexible materials to complex shapes, such as concavities and convexities, while withstanding stresses and environmental conditions like cold and humidity.
Innovation Solution
A method involving shaping flexible material strips with right and left flaps, stitching them together, and using hot melt or heat reactive glue to create a pleated appearance that can be securely laminated onto vehicle parts, allowing for matching complex shapes and providing both aesthetic appeal and structural solidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a pleated appearance is created on flexible material for vehicle interior surfaces, then aesthetic appeal and user attraction are improved, but secure attachment to complex shapes and resistance to environmental stresses deteriorates
Solution Approach 1:
The flexible material is divided into multiple strips that are stitched together to form the pleated appearance. This segmentation allows each strip to be independently shaped and attached, maintaining both the aesthetic pleated effect and secure attachment to complex surfaces while accommodating environmental stresses.
2Adaptability or versatility
If flexible material is used to cover complex shapes including concavities and convexities, then adaptability to passenger compartment surfaces is improved, but firm fixation and durability under stress deteriorates
Solution Approach 1:
The material is segmented into strips that can be independently conforming to complex shapes. The stitching lines act as pivot points that allow the strips to adapt to concavities and convexities while maintaining structural integrity and firm fixation through the stitched connections.
Solution Approach 2:
The pleated structure created by stitching strips together provides inherent curvature and flexibility, allowing the material to conform to complex three-dimensional surfaces including concavities and convexities while maintaining firm attachment through the rigid stitching lines.
3Strength
If stitching is used to create pleated appearance by joining flaps, then structural solidity and shape conformity are improved, but manufacturing complexity and process time deteriorates
Solution Approach 1:
The flaps are prepared and positioned in advance before final stitching. The stitching lines are planned as pivot points that will serve both the pleated aesthetic and structural functions. This preliminary preparation simplifies the overall manufacturing process by organizing complex operations into sequential, manageable steps.

AI summary
The invention relates to a method for covering and decorating a vehicle interior part, comprising installing a decorative surface (100A) made of a flexible surface material, and applying a covering sheet comprising said decorative surface (100A) to the interior part. The method includes preparing strips (10, 20,...) of the flexible material, free from one another, creating right and left flaps (13, 22, 23, ...) on the long sides of said strips, placing the strips side by side to form the decorative surface (100A), and joining at least one right flap (13) with a corresponding left flap (22), said flaps being brought together face to face under the decorative surface, until the covering sheet for said interior part is formed from the free strips with a pleated appearance.
