Double-Cross-Section Vehicle Reinforcing Member for Torsional Stiffness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle reinforcing members with single cross sections struggle to effectively suppress deformation and improve torsional stiffness of vehicle partitions and bodies, limiting their ability to enhance stiffness and strength.
Innovation Solution
A vehicle reinforcing member with a double cross section design, featuring first and second extension portions spaced apart along various axes of the vehicle body, along with upper and lower mounting portions and connection portions, to enhance torsional stiffness and prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a reinforcing member with a single cross section is used, then the structure is simple and easy to manufacture, but the torsional stiffness of the partition and vehicle body is insufficient and deformation cannot be effectively suppressed
Solution Approach 1:
The reinforcing member is divided into multiple extension portions (first extension portion and second extension portion) that are spaced apart from each other. This segmentation creates a multi-cross-section structure that increases torsional stiffness while maintaining manufacturing simplicity through modular design
Solution Approach 2:
The reinforcing member transitions from a single cross-section design to a multi-cross-section design by adding extension portions in different spatial dimensions. The first and second extension portions are arranged at different positions along the longitudinal axis, creating a three-dimensional structure that enhances stiffness without excessive complexity
2Stability of the object's composition
If a reinforcing member with a single cross section is used, then the manufacturing process is simple, but the ability to suppress deformation of the partition and vehicle body is limited
Solution Approach 1:
The reinforcing member is segmented into multiple extension portions (first extension portion and second extension portion) spaced apart along the longitudinal axis. This segmentation provides multiple mounting points and creates a more stable structure that resists deformation while allowing for simplified modular manufacturing
Solution Approach 2:
Different extension portions are positioned at specific locations along the partition to address local deformation needs. The first extension portion and second extension portion are arranged to provide targeted reinforcement at different sections of the partition, improving overall deformation suppression
