Vehicle Structure Foaming Reinforcement Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle structures with hollow structural members lack sufficient strength and rigidity, particularly where different structural portions are coupled, leading to potential deformation.
Innovation Solution
Incorporating reinforcement members with foaming members within the hollow structural members, specifically connecting foaming members to panel portions using supporting members, enhances the rigidity by limiting deformation and providing additional structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If hollow structural members are used to reduce vehicle weight, then weight reduction is achieved, but strength and rigidity become insufficient
Solution Approach 1:
The patent combines the hollow structural member (metal framework) with foam material to create a composite structure. The foam fills the hollow interior space, creating a composite system where the metal provides structural framework and the foam provides bulk stiffness and strength enhancement, resolving the contradiction between weight reduction and strength requirements
Solution Approach 2:
The patent utilizes foam material (a porous material) to fill the hollow structural member. The foam's cellular structure provides weight reduction while maintaining structural integrity, addressing both the weight reduction goal and the strength requirement simultaneously
2Adaptability or versatility
If additional hollow structural portions are added to couple different directions, then structural coverage is improved, but strength and rigidity remain insufficient
Solution Approach 1:
The foam material is specifically placed to fill junction regions where multiple hollow structural portions connect. This composite approach targets the weak points (junctions) with enhanced material properties, providing localized strength and rigidity reinforcement where it is most needed while maintaining the multi-directional structural coverage
Solution Approach 2:
The patent applies foam filling selectively, with particular emphasis on junction regions where structural portions connect. This local quality approach concentrates reinforcement materials where stress concentrations occur, improving strength and rigidity at critical locations without uniformly increasing weight throughout the entire structure

AI summary
A vehicle structure provided with a hollow structural member includes one or more reinforcement members that are located in the hollow structural member and include a foaming member. The hollow structural member includes a first hollow structural portion that is configured by a first panel portion, a second hollow structural portion that is configured by a second panel portion, and a third hollow structural portion that is configured by a third panel portion and couples the first and second hollow structural portions to each other. The one or more reinforcement members include at least one of first and second reinforcement members. The first reinforcement member includes a first foaming member connected to the first and third panel portions. The second reinforcement member includes a second foaming member connected to the second and third panel portions.
