Self-Unlocking Trim Cover for Optional Vehicle Interior Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for providing functional openings in vehicle trim components are inefficient, requiring multiple variants and increasing production costs and logistics effort, as they often necessitate additional assembly steps or compromise on aesthetics.
Innovation Solution
A trim component with a self-unlocking cover that automatically releases the functional opening during assembly, allowing for optional exposure of the opening without additional work steps, using a design where the cover is locked to the component in a force-fitting manner and can be unlocked by applying force perpendicular to the unlocking element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different variants of cladding components are provided (with and without functional openings), then the functional requirements can be met, but logistics effort and production costs increase
Solution Approach 1:
The cladding component is designed with a universal cover that can be locked or unlocked to expose the functional opening. The cover includes a locking element that engages with a locking recess in the default locked state, and an unlocking element that allows the cover to be opened when needed. This universal design eliminates the need for separate variants with and without functional openings, as the same component can serve both purposes through the lockable cover mechanism.
2Adaptability or versatility
If the cover is removed to expose the functional opening, then the functional element can be installed, but additional assembly steps are required
Solution Approach 1:
The cover is designed to be automatically removed during the assembly process when a functional element is present. The functional element itself acts as a tool to unlock the cover by engaging with the unlocking element. When the functional element is inserted into the cladding component, it automatically triggers the cover to open and be removed, eliminating the need for separate manual cover removal steps. This self-service mechanism integrates the cover removal function into the functional element installation process.
3Productivity
If the functional opening remains open without a cover, then no additional assembly steps are needed, but aesthetic appearance deteriorates
Solution Approach 1:
The cover is pre-installed on the cladding component in a locked state before the functional element is installed. This preliminary action ensures that the functional opening is covered and maintains aesthetic appearance during storage, transport, and initial installation. The cover remains in place until the functional element is ready to be installed, at which point the cover is automatically removed. This preliminary covering action resolves the aesthetic concern while maintaining assembly simplicity.

AI summary
The invention relates to a self-releasing cover (14) for a functional opening (24) of a trim component (10) of a vehicle interior. The cover has a lid (16) which can be locked to the functional opening (24) of the trim component (10) such that a front side (16a) of the lid (16) at least partially covers the functional opening (24). Furthermore, the cover (14) has at least one release element (18) which is arranged on a rear side (16b) of the lid (16) facing away from the front side (16a) of the lid (16). The cover (14) is designed such that the release element (18) can be actuated by applying a force to the release element (18) in the direction of the lid (16) and the lid (16) can be deformed and/or displaced by actuating it, and the locking of the lid (16) with the functional opening (24) can be released.Furthermore, the invention relates to a fairing component (10), a vehicle (28) and a method for assembling a fairing component (10).
