Bulkhead Section Cross-Linking Vehicle Body Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle body assembly, the uncoupled portion between the front side inner panel and the side outer reinforce complement creates a closed space that prevents effective shock absorption during side collisions, leading to potential tearing without deformation, and requires a complex assembly of multiple reinforcing parts.
Innovation Solution
The implementation of a bulkhead section that cross-links the front side inner panel and the side outer reinforce complement using a first bulkhead with cross-linking holes and a second bulkhead in the form of a square pillar, which acts as a resistance element to absorb shocks and prevent tearing, reducing the number of parts and assembly processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple reinforcing parts are mounted on the inner surface of the side outer reinforce complement to prepare for side collision, then impact energy can be absorbed, but the number of parts increases, weight increases, and the number of assembly processes increases
Solution Approach 1:
The patent combines multiple reinforcing parts into a single integrated bulkhead structure that includes a bulkhead body, bulkhead ribs, and bulkhead coupling sections. This merging eliminates the need for multiple separate reinforcing components while maintaining the ability to absorb impact energy during side collisions, thereby reducing part count and assembly complexity.
Solution Approach 2:
The bulkhead structure serves multiple functions simultaneously: it reinforces the side outer reinforce complement, couples the front side inner panel to the side outer reinforce complement, and absorbs impact energy during collisions. This multi-functionality replaces the need for multiple specialized components, reducing overall device complexity while maintaining strength.
2Stability of the object's composition
If the internal portion between the front side inner panel and the side outer reinforce complement forms a closed section, then the structure is complete, but welding means cannot enter the internal portion to couple the uncoupled portion
Solution Approach 1:
The bulkhead coupling section acts as an intermediary element that extends from the bulkhead body through the closed internal portion to couple the front side inner panel to the side outer reinforce complement. This intermediary structure allows coupling to be achieved through the closed section without requiring direct access to the internal portion for welding, as the coupling is established through the bulkhead's external mounting points.
3Ease of manufacture
If the uncoupled portion remains between the front side inner panel and the side outer reinforce complement, then assembly is simpler, but the uncoupled portion may be torn without deformation for shock absorption during side collision
Solution Approach 1:
The bulkhead coupling section is pre-configured with coupling holes and mounting structures that enable preliminary coupling of the front side inner panel to the side outer reinforce complement. This preliminary action ensures proper coupling is established before collision events, preventing the uncoupled portion from tearing while maintaining assembly simplicity through the pre-designed coupling interfaces.
