Front Trunk Multi-Action Closure Assembly for Flexible Cargo Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition to electrified vehicles creates space for a front trunk, but existing closure systems are not optimized for easy access and usability, limiting the convenience of loading and unloading cargo.
Innovation Solution
A multi-action closure assembly featuring a rotatable frame and independently movable first and second panels, which can be powered or manual, allowing for various opening and closing configurations to access the front trunk from different angles, enhancing usability and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional single-panel hood closure system is used, then the structure is simple, but the ease of operation for loading and unloading cargo is poor
Solution Approach 1:
The closure assembly is divided into multiple independent panels (first panel, second panel, third panel) that can move relative to each other. Each panel can be opened independently or in combination with others, providing multiple access paths to the front trunk. This segmentation allows users to open only the necessary portion of the closure assembly, improving ease of operation while maintaining a manageable structural complexity through modular design.
2Adaptability or versatility
If multiple panels are added to improve access configurations, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The closure assembly with multiple panels serves multiple functions: it can be opened in different configurations (first panel only, second panel only, both panels together), providing versatile access to the front trunk from different angles. This multi-functionality is achieved through a unified closure assembly structure where panels are connected via hinges and latches, allowing various opening sequences and combinations without requiring separate mechanisms for each access mode.
3Adaptability or versatility
If independent panel movement is enabled, then the adaptability of access configurations improves, but the mechanism complexity increases
Solution Approach 1:
The closure assembly incorporates dynamic elements including hinges that allow panels to rotate relative to each other, and latches that can be engaged or disengaged to lock panels in different positions. The first panel is hinged to the second panel, and the second panel is hinged to the third panel, creating a kinematic chain that enables flexible movement. Powered actuators provide automated movement capability, while manual operation remains possible, allowing the system to adapt to different user needs and scenarios.

AI summary
A front trunk includes a multi-action closure assembly. In some aspects, the techniques described herein relate to a motor vehicle, including: a front trunk establishing a cargo space; a frame rotatably mounted relative to the cargo space; a first panel rotatably mounted to the frame; a second panel rotatably mounted to the frame; and wherein, when the first and second panels are in closed positions, the frame is rotatable to an open position to uncover the front trunk, wherein, when the frame is in a closed position, the first and second panels are rotatable to open positions to uncover the front trunk.
