Roof Hinge Cover Bracket and Locator Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle roof hinge cover mounting systems lack a robust and aesthetically appealing method to securely locate and fixate roof hinge covers onto vehicle roofs, often resulting in inadequate flushness and increased risk of water leakage.
Innovation Solution
A vehicle roof assembly featuring a roof hinge cover with a locator that fits into a locating hole of a roof component, supported by a bracket with multiple sections and clips, ensuring secure attachment and alignment, while maintaining an aesthetically pleasing appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing mounting systems are used to attach roof hinge covers, then the attachment process is simple, but the mounting is inadequate and increases water leakage risk
Solution Approach 1:
The mounting system is divided into multiple functional components: a bracket with multiple sections (first section extending into roof rail, second section establishing beam surface, third section transverse to first and second), multiple clips (first, second, third clips) at different locations, and a locator with locating hole. Each segment performs a specific function - the bracket provides structural support, clips provide attachment points, and the locator ensures proper positioning. This segmentation allows the system to achieve robust mounting while maintaining manufacturability through modular assembly.
Solution Approach 2:
The mounting system employs a nested arrangement where the bracket extends inside the roof rail or roof ditch ornamentation cover, creating a nested structure. The first section of the bracket is received inside the roof rail, while the second section extends outward to support the roof hinge cover. This nesting approach allows the mounting system to be integrated within the existing roof structure without adding excessive external complexity.
2Object-affected harmful factors
If a robust attachment strategy is implemented with multiple clips and locators, then water leakage is minimized and craftsmanship is enhanced, but assembly complexity increases
Solution Approach 1:
The attachment system applies local quality by positioning multiple clips and locators at specific critical locations on the roof hinge cover. The first clip is attached to a first clip housing, the second clip to a second clip housing, and the third clip to a third clip housing, each at different locations. The locator is received through the roof hinge cover and into a locating hole of the roof component. This distributed localization of attachment points ensures comprehensive sealing and structural support at key areas, preventing water leakage without requiring complete coverage that would excessive complexity.
3Strength
If multiple clips and locators are used to secure the roof hinge cover, then mounting strength is improved, but assembly time increases
Solution Approach 1:
The mounting system incorporates preliminary action by pre-positioning the locator with its locating hole to establish the correct position and orientation of the roof hinge cover before the clips are installed. The bracket is also pre-configured with multiple locating openings that guide the placement of clips. This preliminary positioning ensures that when the clips are attached, they engage with pre-aligned features, reducing the time and complexity of the assembly process while maintaining strong mounting.
4Shape
If the bracket extends inside the roof rail or roof ditch ornamentation cover, then aesthetic appearance is improved, but manufacturing complexity increases
Solution Approach 1:
The bracket is segmented into three distinct sections: a first section that extends inside the roof rail or roof ditch ornamentation cover to provide aesthetic integration, a second section rearward of the first section that establishes the beam surface for support, and a third section transverse to the first and second sections. This segmentation allows each portion to be optimized for its specific function - the first section for aesthetics, the second for structural support, and the third for additional attachment points - while simplifying the manufacturing of each individual section.

AI summary
Mounting strategies for locating and securing roof hinge covers to vehicle roofs. An exemplary roof hinge cover may be mounted relative to a roof component (e.g., roof panel, body side panel, bracket, etc.). A locator may be received through the roof hinge cover and into a locating hole of the roof component. One or more clips that are connected to the roof hinge cover may be received within locating openings of a bracket. The bracket supports at least a portion of the roof hinge cover.
