Convertible Trunk Assembly With Tilting Spoiler for Vertical Cargo Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Convertible vehicles face challenges in integrating active spoilers due to limited trunk space and difficulty in opening and closing the trunk lid, especially with a short rear overhang, which affects aerodynamics and usability.
Innovation Solution
A trunk apparatus with a tiltable spoiler cover and a vertically movable trunk assembly, including a lift actuator, link mechanism, and tilt actuator, allowing the spoiler to adjust for aerodynamics and the trunk to expand vertically for increased space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an active spoiler is applied to the rear of the convertible vehicle, then aerodynamic performance is improved, but the difficulty of opening and closing the trunk lid increases
Solution Approach 1:
The spoiler is designed as an active, dynamically adjustable component that can tilt between different angles (including a first angle for aerodynamic performance and a second angle for trunk access). The tilt actuator enables the spoiler to change its configuration based on operational requirements, resolving the contradiction between aerodynamic performance and trunk lid operation ease.
2Shape
If the rear overhang of the convertible vehicle is kept short for aesthetic purposes, then the side profile is improved, but the trunk space is narrowed
Solution Approach 1:
The trunk assembly is designed to move vertically in the height dimension rather than extending horizontally. This vertical movement capability allows the trunk to provide sufficient storage volume despite the short rear overhang, while maintaining the desired aesthetic side profile.
Solution Approach 2:
The trunk assembly is configured as a dynamic, movable structure that can transition between stowed and deployed positions. This dynamic capability enables the trunk space to be expanded when needed while maintaining a compact appearance when not in use, resolving the contradiction between aesthetic profile and functional volume.
3Volume of moving object
If the trunk depth is increased to provide sufficient storage space, then the trunk volume is improved, but the ease of accessing luggage deteriorates
Solution Approach 1:
The trunk assembly is designed as a movable structure that can be deployed upward to bring the storage compartment within easy reach of the user. This dynamic positioning capability allows deep storage volume while maintaining ease of access, as the trunk can be raised to an optimal height for loading and unloading luggage.

AI summary
A trunk apparatus can include a spoiler cover configured to be tiltable at a rear end of a vehicle, and a trunk assembly located below the spoiler cover and configured to move vertically at the rear end of the vehicle. The trunk assembly is configured to move between a stowed position in which the trunk assembly is stowed in an interior space of the rear end of the vehicle and a deployed position in which the trunk assembly is deployed upward from the interior space of the rear end of the vehicle.
