Rollo Assembly Aligning Pins for Guide Channel Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing open roof constructions for vehicles do not effectively maximize daylight performance due to limitations in the design of rollo assemblies, which hinder the alignment and guiding of rollo screen edges and operating beam ends during assembly and disassembly.
Innovation Solution
The rollo assembly incorporates aligning means with fixed position channels and translatable aligning pins that ensure proper alignment and smooth guiding of the rollo screen edges and operating beam ends, allowing for a detachable unit that can be assembled and disassembled without obstructing the roof opening, thereby maximizing daylight performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the guide channels are divided into removable first guide channel part and second guide channel part, then the rollo assembly can be disassembled for maintenance and the effective roof opening is maximized, but the alignment precision between parts may be compromised
Solution Approach 1:
The guide channel is divided into a first guide channel part (removable) and a second guide channel part (fixed), allowing the rollo assembly to be disassembled for maintenance while maintaining proper alignment through aligning pins that ensure precise positioning when reassembled
Solution Approach 2:
Aligning pins are provided to preliminarily establish the correct alignment between the first and second guide channel parts before the rollo screen and operating beam are installed, ensuring that the split guide channels will work together seamlessly without requiring complex adjustment procedures
2Ease of operation
If the aligning pins are made translatable between release position and aligning position, then the ease of assembly is improved, but the device complexity increases
Solution Approach 1:
The aligning pins are designed to be translatable between a release position (for easy assembly/disassembly) and an aligning position (for precise positioning), providing dynamic adaptability that simplifies the assembly process while ensuring proper alignment when engaged

AI summary
A rollo assembly intended for use in an open roof construction for a vehicle, comprises a rotatable winding shaft, a rollo screen of which a rear end can be wound on or off said winding shaft and of which an opposite forward end is provided with an operating beam, and opposite guide channels for in a longitudinal direction guiding opposite side edges of the rollo screen and opposite ends of the operating beam. Each of the guide channels is divided into a removable first guide channel part closest to the winding shaft and a second guide channel part further away from the winding shaft, wherein aligning means are provided for, in an assembled position of the rollo assembly, aligning respective ones of the first and second guide channel parts.
