Convertible Roof Guide Roller Isolator Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current convertible roof designs for SUVs are cumbersome to move between stowed and deployed positions, often resulting in excessive noise and potential damage due to excessive degrees of freedom and inadequate control over guide roller movement, which limits the roof's ability to open fully.
Innovation Solution
A controlled guide roller management system with isolator features to restrict guide roller movement, reducing noise and improving the mechanism's ability to move the convertible roof between closed, sunroof, and further open positions, including an install/release mechanism for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If guide rollers are allowed free movement in guide tracks, then the convertible roof can move between positions, but excessive noise occurs from roller movement
Solution Approach 1:
An isolator component is introduced as an intermediary element between the guide roller and the guide track. This isolator absorbs and dampens the movements and noises generated by the roller, while still allowing the roller to function. The isolator acts as a mediator that permits necessary motion while filtering out harmful noise and excessive movement.
2Adaptability or versatility
If the convertible roof is designed to open fully, then maximum exposure is achieved, but rollers cannot be released from guide tracks
Solution Approach 1:
The isolator component provides dynamic characteristics to the roller-trtrack interface. It allows the roller to move freely within operational limits while automatically restraining it within the guide track boundaries. The isolator's elastic or damping properties enable the system to adapt to different positions (closed, sunroof, fully open) while maintaining roller containment through its restoring force.
3Adaptability or versatility
If excessive degrees of freedom are provided in the mechanism, then the roof can move to various positions, but the roof becomes difficult to move and prone to damage
Solution Approach 1:
The isolator serves as a protective intermediary that limits excessive movements and degrees of freedom. It allows necessary positional flexibility while preventing movements that could lead to damage. The isolator absorbs shock and limits extreme positions, thereby protecting the mechanism from damage while maintaining operational versatility.

AI summary
A panel top assembly for a vehicle including a controlled guide roller management system and install/release mechanism. A pivotal portion, that is rotatable between a closed position and open position, is coupled to guide assemblies slidably connected to guide track assemblies. Each guide track assembly includes a forward isolator assembly that restricts undesired movement/rattling of a roller in a guide track. A rearward isolator assembly restricts undesired movement/rattling of the roller in each guide track, and selectively keeps the roller in the track when the panel top assembly is in a down/open position. The rearward isolator assembly also includes an isolator that selectively allows an opening in the track for releasing the guide assembly from the track to move the panel top assembly to an open/stowed position, and, reinstalling the guide assembly to the track.
