Asymmetric Vehicle Assembly Line Support Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle assembly line configurations are inefficient for mounting large components in the lower part of vehicle bodies due to narrow spaces between support columns, leading to reduced working efficiency and potential component deformation.
Innovation Solution
The vehicle assembly line features a supporting unit with upstream and downstream supporting members positioned asymmetrically across the center line, providing a larger entrance for components and reducing the risk of collision, along with a platform design that allows for easier component carriage and reduced walking distance for assembly workers, incorporating base isolation to prevent vehicle instability during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the supporting unit is disposed in a line symmetrical manner with regard to the center line of the platform, then the structural stability is improved, but the space between support columns becomes narrow making it difficult to carry large components
Solution Approach 1:
The patent applies asymmetry by positioning the support columns not symmetrically but rather at positions that create adequate spacing for component carriage. The support columns are arranged to provide sufficient working space while maintaining structural stability, directly resolving the contradiction between symmetric stability and asymmetric accessibility.
2Device complexity
If the support columns are positioned close together to maintain compact platform design, then the device complexity is reduced, but the working space below vehicle body becomes insufficient for mounting large components
Solution Approach 1:
The patent resolves this contradiction by optimizing the spatial arrangement of support columns to充分利用 the available space. The columns are positioned to maximize the working space area below the vehicle body while maintaining a relatively simple platform structure, effectively using dimensional optimization to balance complexity and space requirements.

AI summary
To improve working efficiency of mounting components in a lower part of a vehicle body, a vehicle assembly line includes a supporting unit to support a vehicle body in a position such that the front direction of the vehicle body is perpendicular to the conveying direction. The supporting unit includes an upstream supporting member and a downstream supporting member provided upstream and downstream of the platform along the conveying direction, respectively. The centers of the support columns fixed to a platform, of the upstream supporting member and the downstream supporting member, are located upstream and downstream, respectively, with respect to a center line CLb of the platform extending in a direction perpendicular to the conveying direction of the platform, and located apart from and opposite to each other across a center line CLa of the platform extending in the conveying direction, to provide a working space for mounting below the vehicle body supported by the carrier device.
