Retractable Top Tapered Slots Roll Cage Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current retractable top designs for modern Jeeps and similar vehicles are limited, as they do not accommodate the new roll cage configuration, which reduces available mounting space and makes it difficult to achieve a secure, windproof seal due to the roll cage's narrow profile and sharp angles.
Innovation Solution
The retractable top design incorporates tapered slots for attachment mechanisms, side mounting, and a flexible enclosure material to navigate the roll cage's angles, along with sealing brackets and a cable system to maintain tension and prevent sagging, allowing for a narrow profile and windproof fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current retractable top designs are used, then the top can be retracted, but the top does not accommodate the new roll cage configuration and cannot achieve a secure windproof seal
Solution Approach 1:
The retractable top employs dynamic linkage arms that can move between retracted and extended positions, allowing the top to adapt its configuration to fit around the roll cage structure while maintaining a secure seal when extended
Solution Approach 2:
The top is divided into multiple linkage arms and support members that can independently position and adjust, enabling the system to navigate the sharp angles of the roll cage while maintaining overall structural integrity and seal effectiveness
2Length of moving object
If the retractable top is mounted on the floor or wheel wells, then mounting is possible, but the profile is not narrow and space is limited due to the roll cage
Solution Approach 1:
The top transitions from floor-based mounting to side-panel mounting, utilizing the vertical dimension of the side panels instead of the horizontal floor space, thereby achieving a narrower profile that accommodates the roll cage configuration
3Ease of operation
If attachment members protrude from the bow arms, then attachment is possible, but the arms cannot rotate close without being impeded
Solution Approach 1:
The connector is recessed within the bow arm structure, with the attachment member nested inside the tapered aperture, allowing the arms to rotate closely together without protruding elements interfering with the motion
4Ease of operation
If the enclosure material is loose, then installation is simple, but the material sags and becomes snagged in the linkage arms
Solution Approach 1:
A cable system is introduced to actively maintain tension in the enclosure material, changing the material state from loose to taut, preventing sagging and snagging while maintaining relatively simple installation

AI summary
A retractable top for a vehicle having an open top, the vehicle including four doors, the retractable top including a left and a right rear roll bar projecting vertically from the rear floor above the vertical walls, the roll bars projecting forward to join a transverse roll bar forming a roll cage, the retractable top including support members attached to two of the three horizontal sides. The retractable top includes linkage arms attached to support members configured to move from a retracted position to an extended position, the linkage arms including a bow arm having a first tapered interconnection aperture, the first tapered interconnection aperture shaped to receive a first connector and recess the first connector such that an end of the first connector is flush with a first surface of the bow arm. The retractable top includes an enclosure material that covers the open top when extended.
