Vehicle Roof Assembly Drive Element Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of assembling a vehicle roof assembly is cumbersome and time-consuming due to the need to thread a flexible drive cable through guides before connecting frame parts, which complicates the assembly process.
Innovation Solution
Divide the drive element into two portions, pre-mounting each in the respective frame parts' guides, and couple them at the connection point between the frame parts, allowing for easier assembly and stable guidance of the drive cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drive cable is threaded through the drive cable guide before connecting frame parts, then the drive cable can be properly positioned, but the assembly process becomes cumbersome and time-consuming
Solution Approach 1:
The drive cable is divided into a first drive cable portion and a second drive cable portion. The first portion is pre-mounted in the first frame part's drive cable guide, and the second portion is pre-mounted in the second frame part's drive cable guide. This segmentation allows frame parts to be connected without threading the entire drive cable through, significantly simplifying the assembly process while ensuring proper positioning of each cable portion in its respective guide.
2Productivity
If frame parts are pre-assembled with drive elements and guides, then assembly efficiency improves, but the drive cable must be threaded through guides after frame connection which complicates the process
Solution Approach 1:
The drive cable is segmented into two portions that can be independently pre-mounted in各自的frame parts. This allows both frame parts to be pre-assembled with their respective drive cable portions already in place, eliminating the need to thread a long flexible cable through the connected frame structure, thus reducing assembly process complexity.
Solution Approach 2:
The drive cable portions are preliminarily mounted in the drive cable guides of the frame parts before the frame parts are connected to each other. This preliminary action ensures that when the frame parts are connected, the drive cable portions are already properly positioned and only need to be coupled together, simplifying the overall assembly process.
3Ease of manufacture
If the drive cable is divided into portions and coupled after frame connection, then assembly is simplified, but additional coupling operations are required
Solution Approach 1:
The drive cable is divided into two portions with coupling elements at their ends. These coupling elements enable simple connection operations after frame parts are assembled, making the coupling process straightforward despite requiring an additional step.
Solution Approach 2:
Coupling elements are provided at the ends of the first and second drive cable portions. These coupling elements act as intermediaries that facilitate the connection between the two drive cable portions after the frame parts are assembled, making the coupling operation simple and efficient.

AI summary
A method of assembling a roof assembly for a vehicle comprises the steps of providing a first frame part (1) having a drive element guide (7), providing a second frame part (8) having a drive element guide (8) and providing a drive element (6) adapted to drive a movable part (4) of the roof assembly and being driven by a drive motor (5). The first and second frame parts (1, 2) are mounted to each other such that the drive element (6) extends from the drive element guide (7) of the first frame part (1) to the drive element guide (8) of the second frame part (2). The drive element (6) is provided as a first drive element portion (6a) and a second drive element portion (6b). The first drive element portion is pre-mounted in the drive element guide (7) of the first frame part (1). The second drive element portion (6b) is pre-mounted in the drive element guide (8) of the second frame part (2). The first and second drive element portions (6a, 6b) are coupled to each other when the first and second frame parts (1, 2) have been mounted to each other.
