Invisible Sliding Door Trim Concealing Rail System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sliding door structures in vehicles are aesthetically compromised and subject to design restrictions due to the visible rail system, which complicates the vehicle body opening mechanism and limits design flexibility, particularly in narrow spaces.
Innovation Solution
An invisible sliding door trim structure comprising a luggage trim, a sliding trim, and a rotating trim that covers the movement of the invisible slider and rotator, respectively, while maintaining the functionality of the sliding door, with the sliding trim sliding along a slider rail and the rotating trim rotating to facilitate door opening and closing, thereby concealing the rail system and enhancing the vehicle's appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a visible rail system is used for the sliding door, then the door can be opened and closed, but the appearance of the vehicle is deteriorated and design restrictions are present
Solution Approach 1:
The rail system is extracted from the visible exterior and relocated to the interior of the door assembly. The door trim is designed to cover the rail structure, effectively removing the visual element that causes appearance deterioration while preserving the mechanical function of the rail for door operation.
Solution Approach 2:
The door trim acts as an intermediary element that mediates between the functional rail system and the aesthetic requirements of the vehicle exterior. The trim covers the rail structure during normal operation, presenting a clean exterior surface while allowing the rail to function internally.
2Ease of operation
If a visible rail system is used for the sliding door, then the door can be opened and closed, but the structure of the vehicle body opening part becomes complicated
Solution Approach 1:
The rail system and door trim are merged into a unified door assembly structure. The trim is integrated with the door body and works in conjunction with the rail to provide both aesthetic coverage and functional support, simplifying the overall vehicle body opening structure by combining multiple elements into a coordinated system.
3Ease of operation
If the center rail is provided on the outer surface of the vehicle body, then the door can slide, but the appearance of the vehicle is deteriorated
Solution Approach 1:
The center rail is extracted from the vehicle body outer surface and repositioned within the door assembly. The door trim covers the relocated rail structure, removing the visual element from the vehicle exterior while maintaining the sliding function internally within the door mechanism.

AI summary
An invisible sliding door trim structure includes a luggage trim provided at one side of a vehicle body opening part opened or closed by a door and including a reception space extended in a horizontal direction, a sliding trim provided at an inner side of the door and slid along the reception space of the luggage trim according to an opening or closing operation of the door, and a rotating trim provided to be rotatable with respect to the sliding trim according to the opening or closing operation of the door. Therefore, an invisible sliding door trim is capable of improving an appearance and overcoming a design restriction problem of a sliding door according to the prior art.
