Vehicle Assembly Guide Rail Layout for Long-Range Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle functional assembly adjustment systems face limitations in installation space, particularly with longer guide rails and cable assemblies, which restrict the adjustment range and visibility in autonomous driving applications.
Innovation Solution
The adjustment apparatus features a guide rail with supporting portions on both sides of the adjusting assembly, where the cable assembly is supported and guided, allowing for efficient use of installation space and concurrent movement with the adjusting assembly, utilizing a deformable cable support device and tensioning mechanism to maintain electrical connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If guide rails are made significantly longer to increase adjustment range, then the adjustment range is improved, but the guide rails occupy more installation space and are more visible from the vehicle interior
Solution Approach 1:
The cable assembly is nested within the guide rail structure, with the cable running through the hollow interior of the guide rail. This nesting allows the cable assembly to be accommodated within the existing guide rail volume, eliminating the need for additional installation space while maintaining the extended adjustment range.
Solution Approach 2:
The cable assembly is routed through the longitudinal axis of the guide rail, utilizing the internal hollow space rather than occupying external lateral space. This dimensional reorganization allows the system to achieve extended adjustment range without increasing the footprint or visibility in the vehicle interior.
2Reliability
If cable assembly is designed to move conjointly with adjusting assembly over longer adjustment path, then electrical connectivity is maintained, but the cable assembly requires more installation space
Solution Approach 1:
The cable assembly is nested within the guide rail's hollow interior, allowing it to move conjointly with the adjusting assembly while being contained within the existing guide rail structure. This eliminates the need for separate cable routing space while maintaining continuous electrical connectivity throughout the extended adjustment range.
Solution Approach 2:
The guide rail serves multiple functions: it provides the structural guide for the adjusting assembly, contains the cable assembly within its hollow interior, and maintains electrical connectivity. This multi-functionality allows the cable assembly to move with the adjusting assembly without requiring additional installation space.
3Ease of operation
If drive motor is arranged in the region of vehicle functional assembly to enable concurrent movement, then adjustment functionality is improved, but installation space in the footwell is restricted
Solution Approach 1:
The drive motor is extracted from the footwell region and positioned in the region of the vehicle functional assembly instead. This relocation eliminates the space conflict in the footwell while maintaining the ability of the drive motor to move conjointly with the adjusting assembly during longitudinal adjustment.
Solution Approach 2:
The drive motor is repositioned from the vertical space below the vehicle functional assembly (footwell region) to the horizontal space within the assembly region. This spatial reorganization resolves the conflict between adjustment functionality and footwell space availability.

AI summary
An adjustment apparatus for longitudinal adjustment of a vehicle functional assembly comprises a guide rail which extends along a longitudinal axis, an adjusting assembly which can be adjusted on the guide rail along the longitudinal axis and is assigned to the vehicle functional assembly, and a cable assembly. It is provided here that the guide rail has a first supporting portion which extends along the longitudinal axis and a second supporting portion which extends along the longitudinal axis, wherein, as viewed along a transverse direction transversely with respect to the longitudinal axis, the first supporting portion is arranged on a first side of a portion of the adjusting assembly and the second supporting portion is arranged on a second side of the portion of the adjusting assembly, and the cable assembly is supported with a first portion on the first supporting portion and with a second portion on the second supporting portion.
