Preassembled Roller Shutter Drive for Cargo Separators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of separating devices in motor vehicles is often complex and requires numerous assembly steps due to the need for precise alignment of guide rails, transmission means, and drive components, which can lead to functional impairments and increased assembly time.
Innovation Solution
A separating device with a channel component that includes guide channels for excess transmission lengths and a preassembled assembly of the drive device and roller blind arrangement, allowing for easier installation by reducing the number of fastening points and simplifying the alignment of components, along with a cassette-free roller blind design and pivotable guide tubes for space-saving transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the separating device is installed with separate guide rails and drive components, then the device can be installed in the vehicle, but the assembly process becomes complex and requires numerous assembly steps
Solution Approach 1:
The patent combines the guide rails, drive device, and roller blind arrangement into a preassembled unit. This merging of previously separate components into an integrated assembly reduces the number of assembly steps required during vehicle installation, directly addressing the contradiction between ease of manufacture and device complexity.
Solution Approach 2:
The guide rails and drive device are preassembled and prepositioned in the correct relative positions before installation in the vehicle. This preliminary action ensures that components are already aligned and connected during the manufacturing phase, eliminating the need for complex alignment and multiple assembly steps during vehicle installation.
2Ease of operation
If the transmission means are guided in guide tubes, then the transmission means can be displaceably guided, but excess lengths of transmission means can cause functional impairments and contamination
Solution Approach 1:
The guide tubes are designed to receive and contain the transmission means, including any excess lengths, within their internal space. The transmission means are nested within the guide tubes, which protects them from contamination and prevents functional impairments caused by loose or improperly guided cables.
Solution Approach 2:
The guide tubes act as protective enclosures that accommodate the flexible transmission means while preventing contamination. The tubular structure provides a controlled environment that maintains reliability while allowing the transmission means to move freely during operation.
3Manufacturing precision
If the guide rails are firmly attached to the side panels in correct positions, then the separating device can function properly, but the installation process becomes difficult and time-consuming
Solution Approach 1:
The guide rails are prepositioned and firmly attached to the side panels in the correct positions during the preassembly phase. This preliminary action ensures precise alignment is achieved before the final installation, eliminating the need for time-consuming adjustment and alignment work during vehicle installation.
Solution Approach 2:
The guide rails are combined with the drive device and roller blind arrangement in a preassembled unit, where the relative positions and alignments are already established. This merging allows the entire assembly to be installed as a single unit, significantly reducing installation time while maintaining the required precision through pre-established geometric relationships.
