Vehicle Assist Handle Assembly With Concealed Headliner Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional assist handles for vehicles have complex configurations, leading to difficulties in assembly, increased noise due to torsion between components, potential damage from strong forces, and improper assembly or detachment issues, which compromise the comfort and aesthetic quality of the vehicle interior.
Innovation Solution
An assist handle design where the handle is fixed to a roof panel and passes through a headliner, featuring a vessel-shaped body with fixing protrusions and grooves for secure assembly, and a sliding or rotating cover to maintain a built-in state when not in use, reducing the number of components and simplifying assembly while preventing deformation and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the assist handle is assembled integrally with the installation bracket using module clips based on the headliner, then the assembly structure is complete, but the configuration becomes complicated and assembly becomes difficult
Solution Approach 1:
The patent extracts the handle from the complex module clip assembly and directly fixes it to the vehicle body (roof panel). This simplifies the assembly configuration by removing unnecessary intermediate components while maintaining reliable fixation through direct mounting.
2Reliability
If multiple components are used to assemble the assist handle, then the assembly is complete, but torsion occurs between components causing abnormal sounds
Solution Approach 1:
The patent merges the handle and installation bracket into a simplified assembly with fewer components. By reducing the number of connecting portions, it eliminates torsion between multiple components that causes abnormal sounds, while still achieving complete and reliable assembly.
3Reliability
If the assist handle is mounted on the headliner as a module, then the assembly is complete, but strong external forces can damage connecting portions
Solution Approach 1:
The patent performs preliminary action by directly fixing the handle to the vehicle body (roof panel) before headliner assembly. This strengthens the connection to withstand external forces, as the handle is securely anchored to the structural body rather than relying on weaker headliner mounting.
4Ease of operation
If the assist handle components are not sequentially assembled, then assembly flexibility is maintained, but improper assembly or detachment occurs
Solution Approach 1:
The patent segments the assembly into clear sequential steps: (1) fix handle to roof panel, (2) assemble headliner over handle. This segmentation provides assembly flexibility through clear stages while ensuring reliability by establishing a proper assembly sequence that prevents improper assembly or detachment.
5Ease of operation
If the handle is exposed in the vehicle interior, then the assist function is accessible, but the aesthetic sense and appearance are compromised
Solution Approach 1:
The patent applies local quality by making the handle invisible only at specific locations where aesthetics matter. The handle passes through the headliner and remains hidden within the vehicle interior, while still being accessible for use. This local concealment preserves overall aesthetic appearance without compromising assist functionality.

AI summary
An assist handle for a vehicle may be held by hand by mounting the assist handle on a roof panel in advance and then allowing the assist handle to be exposed to an interior by passing through a headliner when the headliner is mounted on the roof panel, thereby safely using the assist handle by firmly fixing the assist handle to a vehicle body and assembling the assist handle simply and conveniently by reducing the number of components. In particular, by forming a cover, which is opened or closed in a sliding manner or rotation manner, on a portion on which the assist handle is mounted of the headliner, the assist handle may maintain a built-in state when not used. In addition, by mounting a body in a vessel shape on a surface of the headliner and allowing the body to be forcibly fitted into the assist handle, it is possible to prevent the headliner portion from being lifted or deformed even when the assist handle is used by being held by hand, thereby conveniently using the assist handle.
