Front Trunk Closure Assembly With Dual Deployed Access Positions
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 for this compartment lack flexibility and usability in different deployment positions, limiting access and functionality.
Innovation Solution
A closure assembly with an upper and lower section, where the lower section is independently movable between a closed, intermediate deployed, and fully deployed position, with specific rotational mechanisms and surface area configurations to enhance loading, unloading, and usability, including a table top surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lower section is configured to move between closed, intermediate deployed, and fully deployed positions, then access and usability are improved, but device complexity increases
Solution Approach 1:
The closure assembly is divided into an upper section and a lower section that can move independently. The lower section is further segmented into a closure panel and a table top panel that can rotate relative to each other. This segmentation allows the closure assembly to achieve multiple deployed positions (closed, intermediate, fully deployed) by moving individual segments independently, thereby improving access and usability without requiring a completely complex redesign of the entire closure system.
2Adaptability or versatility
If the lower section provides increased surface area in fully deployed position, then cargo and entertainment functionality are improved, but structural complexity increases
Solution Approach 1:
The lower section of the closure assembly is designed to serve multiple functions through its ability to assume different positions. In the closed position, it provides secure closure. In the intermediate deployed position, it enables cargo access. In the fully deployed position, it creates an extended surface area that functions as both a cargo platform and an entertainment surface (such as a table top). This multi-functionality is achieved by integrating the table top panel into the lower section, allowing a single structural element to fulfill multiple purposes without requiring separate dedicated components for each function.
3Ease of operation
If the first and second panels are moveable independently, then loading and unloading convenience are improved, but mechanical complexity increases
Solution Approach 1:
The closure assembly transitions from a static, fixed structure to a dynamic system where the closure panel and table top panel can rotate independently relative to each other. This dynamic capability allows the panels to adapt their positions during loading and unloading operations, enabling convenient access to the cargo space while maintaining a simplified mechanical connection through rotation axes that allow movement without complex actuation mechanisms.

AI summary
A front trunk includes a closure section configurable into two deployed positions, namely an intermediate deployed position and a fully deployed position. 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 selectively cover and uncover the front trunk, wherein the closure assembly includes an upper section and a lower section moveable independent of the upper section, wherein the lower section is configured to move between a closed position, an intermediate deployed position in which the lower section uncovers a portion of the front trunk, and a fully deployed position in which an upper surface area of the lower section is greater than the upper surface area of the lower section in the intermediate deployed position.
