Integrated Vehicle Door Portal Assembly for Crash Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for assembling vehicle door portals in road and rail vehicles is labor-intensive and costly, requiring individual assembly of numerous components, which complicates series production and flexibility in design.
Innovation Solution
A door system assembly comprising a door frame, a door leaf attached via a support device, and means for moving the door leaf, designed to be installed as a whole within the vehicle, forming an integrated vehicle door portal that enhances stability and crash behavior, thereby simplifying assembly and reducing component costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual assembly of numerous door components is performed, then assembly flexibility and adaptability are maintained, but assembly effort and production cost increase significantly
Solution Approach 1:
The patent combines multiple door components (door frame, door leaf, support device, moving means) into a single integrated door system assembly that is installed as one unit. This merging of components eliminates the need for individual assembly of multiple parts, significantly reducing assembly effort while maintaining design flexibility through modular assembly at the system level
2Adaptability or versatility
If numerous door components are assembled individually, then component adaptability is maintained, but assembly time and production cost increase
Solution Approach 1:
The door system assembly is pre-assembled with all necessary components (door frame, door leaf, support device, moving means) integrated together before installation in the vehicle. This preliminary assembly action is performed at the manufacturing stage, eliminating time-consuming on-site assembly operations and reducing production cycle time
3Stability of the object's composition
If traditional door portal design is used, then structural integration is maintained, but assembly complexity and cost increase
Solution Approach 1:
The invention segments the door system into a self-contained modular assembly unit that includes all necessary components (door frame, door leaf, support device, moving means). This segmentation allows the complex door system to be managed as a single module with simplified installation procedures, reducing assembly complexity while maintaining structural integration through the unified design of the modular assembly
