Interior Component Assembly with Wrapped Edge Insertion Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing combination structures of interior components, such as vehicle door trims, the optical fiber upholstery material is prone to crushing and distortion at acute or obtuse angle portions during manufacturing, leading to defects in the design surface.
Innovation Solution
A combination structure where a protruding portion is provided on the outer edge of the base material, allowing the upholstery material to be wrapped around it, and an insertion portion on the second component to receive this protruding portion, preventing defects by maintaining the design quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the optical fiber upholstery material is wrapped around to the back surface at acute angle portions while strongly pulling the outer edge portion, then the upholstery material can be properly installed on the base material, but the optical fiber upholstery material is partially crushed which reduces the thickness of the sheet or distorts the design surface
Solution Approach 1:
The base material is divided into a front surface portion and a back surface portion that are separated by a stepped portion. This segmentation allows the upholstery material to be wrapped around the stepped portion without requiring strong pulling forces, thereby preventing crushing and distortion while maintaining proper installation.
Solution Approach 2:
The invention introduces a stepped portion that creates a vertical dimension (height difference) between the front surface portion and back surface portion of the base material. This dimensional change provides a physical guide for wrapping the upholstery material, eliminating the need for strong pulling forces and preventing damage to the design surface.
2Area of stationary object
If the upholstery material is wrapped around at obtuse angle portions, then the base material can be fully covered, but the same problem of crushing and distortion occurs
Solution Approach 1:
The base material is segmented into front and back surface portions separated by a stepped portion, allowing the upholstery material to be wrapped around this stepped structure. This ensures full coverage of the base material while the stepped portion prevents the need for strong pulling forces that would cause crushing or distortion.

AI summary
A combination structure is a combination structure of a first interior component and a second interior component. The first interior component includes a base material and an upholstery material covering a surface of the base material. A protruding portion is provided extending from an outer edge of the base material. An outer edge portion of the upholstery material is laid on and wrapped around the protruding portion. The second interior component is provided with an insertion portion configured to receive insertion of the protruding portion.
