Solution Overview

Problem

Existing vehicle roof assemblies compromise head space due to the need for mounting means and sunblind systems that require positioning further away from the roof panel, reducing occupant comfort and space.

Innovation Solution

A vehicle roof assembly design featuring a mounting frame with angled flanges that allow the panel device to be adjusted in position without requiring additional space for mounting means, thereby maintaining head space by integrating the mounting flange between the panel and mounting means levels, allowing for flush mounting and easy access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If mounting means and sunblind systems are positioned further away from the roof panel to enable accessibility and operation, then ease of operation is improved, but head space is reduced

Engineering Contradiction:
Improveaccessibility of mounting meansVSAvoidhead space
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The mounting flange is nested within the space between the roof panel and the mounting means, allowing the mounting structure to be integrated into the existing vertical space rather than requiring additional external space. This nesting approach enables the mounting means to be accessible while maintaining head space by utilizing the space between structural components.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The first flange extends in a direction away from the first main surface (perpendicular to the mounting flange), creating a three-dimensional arrangement where mounting accessibility is achieved through lateral extension rather than vertical displacement. This dimensional change allows mounting operations without compromising head space in the vertical direction.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Volume of moving object

If mounting means are positioned closer to the roof panel to maintain head space, then head space is improved, but ease of operation deteriorates due to reduced accessibility

Engineering Contradiction:
Improvehead spaceVSAvoidaccessibility of mounting means
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The mounting frame is segmented into multiple flanges with distinct functions: the second flange provides the mounting surface close to the roof panel for maintaining head space, while the first flange extends outward to provide accessibility for mounting operations. This segmentation allows each component to fulfill its function without compromising the other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first flange acts as an intermediary element that connects the compact mounting structure (second flange near the panel) with the operational interface (mounting means). It mediates between the space-constrained mounting location and the accessibility requirement, allowing operators to access mounting means without requiring the mounting structure itself to be positioned far from the panel.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If additional space is allocated for mounting means to ensure proper installation and adjustment, then ease of manufacture is improved, but head space is reduced

Engineering Contradiction:
Improveinstallation of panel deviceVSAvoidhead space
Core Design Contradiction:
Ease of manufactureVSVolume of moving object

Solution Approach 1:

The mounting frame integrates multiple functions into a single structure: the second flange provides the mounting surface, the first flange provides operational accessibility, and together they enable easy installation without requiring separate additional space. This merging of functions into a compact integrated structure allows ease of manufacture while preserving head space.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A vehicle roof assembly for covering at least a part of a passenger compartment of a vehicle comprises a mounting frame and a panel device. The panel device comprises a cover panel and a mounting bracket comprising a mounting flange. The mounting frame comprises a first flange and a second flange under an angle. The second flange comprises a mounting means for attaching the mounting flange. The first flange is configured to be extending towards the passenger compartment. The mounting flange is attached to the second flange at the mounting means. In a mounted state, at least a part of the first flange is arranged closer to the cover panel than the mounting means such that head space is preserved.
