Retractable Vehicle Roof System with Nested Panel Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle closure systems require storage space for closure panels when in the open position, increasing vehicle height or reducing interior space, and external storage risks damage and complicates user operation.
Innovation Solution
A closure system with movable support members and flexible panels that fold into a recessed position, allowing the panels to be stored within the support members when open, maintaining a sleek design and preventing debris entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If closure panels are stored between the outer panel and headliner when in open position, then the panel is protected and easily accessible, but the vehicle height increases and/or interior compartment size is reduced
Solution Approach 1:
The closure panel is nested within the support member structure when in the open position. The support member contains a cavity or recess that receives and stores the closure panel, allowing the panel to be housed within the existing structural envelope of the vehicle rather than requiring additional external storage space.
2Ease of operation
If closure panels are removed from the vehicle to expose the passenger compartment, then adequate exposure is achieved, but storage complexity increases and utility is diminished
Solution Approach 1:
The support member serves multiple functions: it provides structural support for the closure panel, acts as a storage container for the panel when open, and integrates with the vehicle body structure. By combining these functions into a single integrated component, the system eliminates the need for separate storage mechanisms.
3Volume of stationary object
If closure panels are stored in external spaces such as a garage, then storage space within the vehicle is preserved, but the panels may become damaged and user convenience is reduced
Solution Approach 1:
The closure panel is nested within the protected environment of the support member, which is itself integrated into the vehicle structure. This nested arrangement ensures the panel remains protected from external damage while maintaining easy access, eliminating the need for external storage.

AI summary
A closure system for a vehicle includes a closure member movable relative to the vehicle between an open position and a closed position. The closure member includes a flexible panel and a plurality of support members supporting the flexible panel. A first support member is attached to and is movable with the closure member between the open position and the closed position. The first support member includes a recess receiving the flexible panel and the plurality of support members therein when the closure member is in the open position.
