Interior component for conveyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching a skin material to a vehicle interior component require significant manual effort and time, especially when using adhesive agents or multi-point fixation techniques, leading to difficulties in reducing man-hours and preventing slack wrinkles and aesthetic issues.
Innovation Solution
Incorporating linear locking members at the end portions of the skin material, which are attached to the base material in a non-visible position, allowing for linear pulling and fixation without adhesives, thereby simplifying the attachment process and reducing man-hours while minimizing slack wrinkles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive agents or multi-point fixation techniques are used to attach skin material to base material, then the skin material can be fixed securely, but the work process becomes complex and requires significant manual effort and time
Solution Approach 1:
The invention divides the fixation function into two parts: locking pieces embedded in the base material and engagement holes formed in the skin material. This segmentation allows the skin material to be fixed securely through mechanical interlocking without requiring adhesive agents or complex multi-point fixation techniques, thereby improving work efficiency while maintaining fixation reliability
Solution Approach 2:
The locking pieces are pre-embedded in the base material before the skin material is attached. This preliminary action simplifies the attachment process by providing ready-made engagement points, eliminating the need for complex adhesive application or multi-point fixation operations during assembly, thus improving productivity
2Reliability
If adhesive agents are used to fix the skin material, then the skin material can be securely attached, but the work process complexity increases and additional steps are required
Solution Approach 1:
The invention replaces the chemical bonding mechanism of adhesive agents with a mechanical interlocking system consisting of locking pieces and engagement holes. This substitution eliminates the need for adhesive application steps and drying time, reducing process complexity while maintaining secure attachment through mechanical interlocking
3Reliability
If the skin material is fixed using traditional methods, then the attachment can be achieved, but slack wrinkles occur and the end portion may come off from locking pieces
Solution Approach 1:
The invention forms engagement holes at specific locations in the skin material that correspond to the positions of locking pieces in the base material. This localized quality enhancement at critical fixation points ensures the skin material is securely held without slack wrinkles, improving both fixation stability and surface quality
Solution Approach 2:
The skin material itself is modified by forming engagement holes in it, allowing it to actively participate in its own fixation process. The engagement holes in the skin material work together with the locking pieces to create a self-fixing mechanism that prevents slack wrinkles and coming off, improving both fixation stability and surface quality

AI summary
An interior component for a conveyance having a design surface includes a base material and a skin material covering the base material. The skin material includes linear locking members at end portions of the skin material, and the linear locking members are attached at positions that are not visible from a design surface side of the base material. Since the linear locking members are provided at the end portions of the skin material, the skin material is linearly pulled, so that slack wrinkles of the skin material can be suppressed when the base material is covered with the skin material. In addition, since the linear locking member is attached at a position that is not visible from the design surface side, the skin material can be fixed without using an adhesive agent.
