Front Trunk Closure Assembly for Headroom and Shade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition from internal combustion engine vehicles to electrified vehicles creates space for a front trunk, but existing closure systems do not effectively provide increased headroom and shade, limiting the usability of this new cargo space, especially in environments like worksites and tailgating events.
Innovation Solution
A closure assembly for the front trunk comprising a hood section and a grille section that rotates relative to each other, with a powered assembly moving the closure assembly from a closed to an open position while rotating the grille section to increase headroom and adjust its angle, and an electronic visual display that rotates to be perpendicular to the ground, enhancing usability and providing shade.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the closure assembly is opened to access the front trunk, then access to cargo space is enabled, but headroom and shade are reduced
Solution Approach 1:
The grille section is designed to be rotatable relative to the hood section, allowing it to dynamically adjust its position. When the closure assembly is opened, the grille section can rotate to extend upward, creating shade and headroom over the cargo space. This dynamic adjustment resolves the contradiction by enabling the grille to provide protective functions during the open state when these functions would normally be absent.
2Device complexity
If the grille section is fixed relative to the hood section, then structural simplicity is maintained, but headroom and shade adjustment capability is limited
Solution Approach 1:
The grille section incorporates a rotation mechanism that allows it to change its angle relative to the hood section. This dynamic capability enables the grille to adjust its position to provide varying degrees of headroom and shade, significantly enhancing adaptability without adding excessive complexity to the overall closure assembly structure.
3Ease of operation
If the closure assembly is opened fully, then cargo access is maximized, but shade provision is reduced
Solution Approach 1:
The rotatable grille section can be positioned at different angles independent of the closure assembly's open state. Even when the closure is fully opened for maximum cargo access, the grille section can rotate to extend upward and provide shade, decoupling the shade provision function from the closure position and maintaining illumination control regardless of how open the trunk is.

AI summary
This disclosure relates to a front trunk including a closure providing increased headroom and shade. In some aspects, the techniques described herein relate to a motor vehicle, including: a front trunk establishing a cargo space; and a closure assembly configured to move between a closed position and an open position to selectively cover and uncover the front trunk, wherein the closure assembly includes a hood section and a grille section, wherein, when the closure assembly is not in the closed position, the grille section is rotatable relative to the hood section in a direction away from a ground surface.
