Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The precise installation of door drives on vehicle bodies is complex and time-consuming due to manufacturing tolerances, requiring spacers and additional components, which affects door panel positioning and operational efficiency.
Innovation Solution
A device with detachable brackets and adjustable threaded rods allows for quick, precise, and easy alignment of door drives relative to the vehicle body, enabling adjustment in multiple spatial directions and angles without additional support equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If spacers of varying thicknesses are used to adjust door drive position, then positioning precision is improved, but device complexity and assembly time increase
Solution Approach 1:
The invention extracts and eliminates the need for spacers and intermediate layers by integrating adjustment functionality directly into the bracket system. The threaded rod mechanism allows direct positioning without requiring additional spacer components, thereby reducing device complexity while maintaining positioning precision.
Solution Approach 2:
The bracket system is designed as a universal adjustment mechanism that can position the door drive in multiple spatial directions (longitudinal, transverse, and angular) using a single integrated structure. This multi-functional design replaces the need for multiple specialized components like spacers, reducing overall complexity.
2Manufacturing precision
If multiple spacers and intermediate layers are used for adjustment, then positioning accuracy is improved, but assembly time and labor requirements increase
Solution Approach 1:
The brackets are pre-equipped with threaded rods and adjustment mechanisms during manufacturing, so that positioning can be achieved directly at the installation location without requiring time-consuming on-site assembly of multiple spacers and intermediate layers. This preliminary preparation significantly reduces assembly time.
Solution Approach 2:
The invention merges the functions of multiple separate components (brackets, spacers, intermediate layers) into a single integrated adjustment device. This consolidation allows all positioning adjustments to be made through one mechanism, reducing the number of operations required and thereby reducing assembly time.
3Adaptability or versatility
If traditional adjustment methods with spacers are used, then positioning capability is improved, but the number of components and device complexity increase
Solution Approach 1:
The invention introduces a dynamic adjustment mechanism using threaded rods that allow the door drive position to be modified during assembly. This dynamic capability provides versatility in positioning without requiring multiple static spacer components, as the same mechanism can adjust the door drive in various positions along the longitudinal, transverse, and angular axes.
