Sliding Side Door Anchor Plate Positioning for Rail Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for aligning sliding side doors on vehicles are not standardized, making them inefficient for mass production, as adjustments are customized and made manually after the door is attached, leading to variations in alignment and aesthetics issues.
Innovation Solution
A method involving a jig and anchor plates to secure and adjust the position of the sliding side door, ensuring proper alignment with the vehicle body by determining a desired position for the anchor plate before attachment, allowing for consistent alignment across multiple vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual customization is used for door alignment adjustment, then alignment accuracy can be achieved, but production efficiency deteriorates due to non-standardized processes
Solution Approach 1:
The patent applies preliminary action by pre-determining the anchor plate position on the door before the door is attached to the vehicle body. The desired position is calculated based on prototype vehicle measurements and alignment requirements, then this predetermined position is used during production to ensure proper alignment without requiring manual adjustment after assembly. This resolves the contradiction by establishing precision through advance planning rather than post-assembly customization.
Solution Approach 2:
The patent changes the parameter of anchor plate position from a variable requiring manual adjustment to a fixed predetermined value. By calculating the desired position using the formula that incorporates prototype door alignment measurements and applying this as a standard, the system transforms the alignment process from customized manual work to a standardized parameter-based approach, thereby improving both precision and productivity.
2Productivity
If standardized positioning is implemented for anchor plates, then production efficiency improves, but adaptability to individual vehicle variations deteriorates
Solution Approach 1:
The patent uses copying by measuring the alignment characteristics of a prototype vehicle and door assembly, then replicating these measurements as the desired position parameters for production vehicles. The prototype serves as a template that captures the optimal alignment configuration, which is then copied and applied标准化 to all subsequent vehicles. This allows standardized production while maintaining adaptability to the specific vehicle design through the prototype-based parameter determination.
3Manufacturing precision
If anchor plate position is determined after door attachment, then alignment accuracy can be achieved, but production time increases due to post-assembly adjustments
Solution Approach 1:
The patent eliminates post-assembly adjustment by performing the position determination action beforehand. The desired anchor plate position is calculated and established before the door is attached to the vehicle body, using prototype measurements and predetermined formulas. This preliminary determination of parameters ensures that when assembly occurs, the correct position is already known and can be directly applied, thereby achieving both accuracy and time efficiency.

AI summary
A method of properly aligning a sliding side door on a vehicle includes first preparing a prototype vehicle and determining how far out of alignment the door is to the body of the prototype vehicle. This amount of misalignment is then used to adjust the attachment position of an anchor plate to a sliding side door of the vehicle, so that the anchor plate is attached at a desired position to the production vehicle, which causes there to be no misalignment between the sliding side door and the body of the production vehicle. A jig is used to hold the anchor plate at the desired location while welding the anchor plate to the door. A roller assembly is then attached to the anchor plate and to a rail on a body of the vehicle.
