Solution Overview
Problem
The vehicle body of purpose-built vehicles (PBVs) requires enhanced connection robustness and structural strength, particularly for side collisions, while maintaining the integrity of the fixed glass application.
Innovation Solution
A side body structure for a vehicle that includes a center pillar with an outer flange part and a joint member connected to the side sill, providing increased structural strength and connection robustness through a reinforced coupling system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed glass is applied to the side body structure, then connection robustness of members is improved, but structural strength for side collisions deteriorates
Solution Approach 1:
The side body structure is divided into multiple functional components: center pillar, outer flange part, joint member, and side sill. This segmentation allows each component to be optimized for its specific function - the center pillar and outer flange part provide glass mounting stability, while the joint member and side sill configuration enhance side collision resistance independently.
Solution Approach 2:
The side body structure employs composite construction with the center pillar, outer flange part, joint member, and side sill forming an integrated composite structure. This composite design combines the strengths of different structural elements to simultaneously achieve connection robustness for fixed glass and structural strength for side collision protection.
2Device complexity
If the center pillar and side sill are directly connected, then device complexity is reduced, but connection robustness deteriorates
Solution Approach 1:
The joint member serves as an intermediary component between the center pillar and side sill. This mediator enhances the connection robustness by providing a dedicated interface for force transmission and structural integration, while the outer flange part acts as another intermediary that facilitates the fixed glass connection to the center pillar. These intermediary elements add controlled complexity that significantly improves overall connection reliability.
